What should I do if the knife holder of roller skates slips, and what should I do if I can t get it

Nail slip can be done in the following ways.

Use a hammer to hammer a larger screwdriver into it, and then screw it.

In addition, there is a special tool for handling slippery wires, called broken wire extractors. It is possible to break the nail and take it out.

There is no way to slip the knife holder, so you can only change the tool holder. Even if you use tapping to do the thread again, the diameter is not the same as the original.

I didn't see it a few days ago, it's late, sorry! You're flat shoes, right? If so, can the nails be removed?

If you can't take it out, as the second floor said, hit it with an electric drill first (beware of hurting the knife holder). If you can take it out but can't tighten it, you can go to find a pair of casual shoes (that is, the kind of plastic knife holder roller skates that children play with), the nails on this kind of shoes are threaded on both sides of the thread (the nails of the flat flower are different), you can not rely on the thread of the original knife holder to tighten the nails; But it's best to put a spring washer in the middle or something, so as not to loosen and cause danger. Casual shoes are studded, many ** are sold, go search for it yourself, and you won't give the link. Hope!

If it is a nail slippery wire, you can use an electric drill to pierce the nail, take out the nail, and replace it.

Re-tapping, buy 8mm taps (the original nails are 6mm), and then buy 8mm nails, when tapping, it must be vertical, that is, to ensure that it is on a line with the original nails!

I suggest you change the knife holder.

There are two ways to wear spikes on roller skates and not get them down:

If the roller skates are rusty, you can soak them in engine oil for a few hours before trying them with various tools, and try to lengthen the arm as much as possible, such as the handle of an extension wrench. If there is rust in the erection accidentally, but there is a problem with the wide acacia in the mechanical aspect, it can only be solved by manually making corners, such as using a file to grind out a parallel straight line on both sides of the screw and then unscrew it down with a wrench, or making a horizontal line in the middle of the screw and then screwing it with a screw cutter.

Hardware store, buy a slippery wire extractor, a small one, a set of more than ten yuan.

How do you use a wrench? Isn't there a knife change? Could it be that the direction is wrong?

Let's use two knives to get it! If it's smooth, it should be more troublesome to change the wheel, but it won't be impossible to take it out...Dude, if you really can't do it, just call a professional to help you get it...Have a nice day. I also like roller skating.

The wheels were sawed off with a hacksaw, and then the rotors and nails inside were sawed off as well. As long as he can make it, you can saw it down. I used to do this a lot. No problem for sure. You try

There are two ways to do this:

1. If it is rusty, soak it in engine oil for a few hours and then try it with various tools, and try to lengthen the arm as much as possible, such as the handle of an extension wrench.

2. In the machine, it can only be taken by manually making corners, such as using a file to grind out parallel straight lines on both sides of the screw and then unscrew it with a wrench, or screwing it with a screwdriver after making a horizontal line in the middle of the screw.

Buy a professional nail extractor online, it's not too expensive, but it's very easy to use, much better than a wrench, or you have to try a violent way, it's too easy to damage your shoes.

Dude, you're so unlucky. I'll sympathize with you first! Then tell me about my experience.

1. In the best case, your nail hole has not been twisted round, in the hardware store, buy a thicker wrench to unscrew it, the original wrench is too thin to give force.

2. If it is more miserable, the nail is twisted round, and the car repairer will knock it down with a tool, or drill it down with an electric drill (the latter may destroy the thread).

3. There seems to be a broken wire extractor on the Internet, and I won't evaluate it if I haven't used it.

Go to Lao A and buy a 25 yuan one, it's super powerful.

You can remove Minshan's old shoe buckle with a tool, and then install the newly bought shoe buckle.

Roller skating, commonly known as roller skates, originated in the Netherlands, is a kind of competition that uses special roller skates as a competition tool, and is also a kind of life and leisure. Most of today's skaters mainly use inline wheels, also known as yo-yo bridge cha medium, 66. (Inline skaters are nicknamed for the sport, the sound of wheels rubbing against the ground during skating, as well as skating on the road as "brushing").

The origins of roller skates are interesting. It is said that as early as 1100, hunters put bones under the soles of long leather shoes in order to hunt even in winter, which is considered to be the earliest style of ice skates. In 1760, a London-based musical instrument maker, Josif Marin, invented a pair of skates with wheels, which were small and made of metal.

Re-tapping, buy 8mm taps (the original nails are 6mm), and then buy 8mm nails, when tapping, it must be vertical, that is, to ensure that it is on a line with the original nails!

The main points of tapping are as follows:

Aluminum alloy tapping lubrication, can be brushed on the tap with some 10-20% concentration of lubricating coolant, which is conducive to the tap cutting.

The position of the workpiece clamping should be correct, and the center line of the threaded hole should be placed in the horizontal or vertical position as much as possible, so that it is easy to judge whether the axis of the tap is perpendicular to the plane of the workpiece, so as to prevent the tapping thread from being skewed due to improper threading.

At the beginning of tapping, try to put the tap in the right place, then slightly press the tap and rotate the wringer, when cutting into 1-2 turns, carefully check and correct the position of the tap. Generally, when cutting into 3-4 turns of thread, the tap position should be correct. In the future, it is only necessary to turn the winch and no more pressure should be applied to the tap, otherwise the thread shape will be damaged.

When tapping, every time the winch is turned 1 2 1 turns, it should be reversed about 1 2 turns, so that the chips are easy to discharge after breaking, and can reduce the phenomenon that the cutting edge rolls the tap due to sticky chips. When encountering a screw hole (blind hole) that cannot be reached, it is necessary to withdraw the tap frequently and use a brush to remove the chips in the hole.

When tapping the screw hole of plastic material, lubricating coolant should be added. For steel, oil or emulsion with a large concentration can generally be used to prevent the tap from breaking.

If the slippery wire is used, it can be taken out with a broken wire extractor, but if it still doesn't work, you can only saw the wheel.

What is tapping?

OK. Speed skates are taller than flat shoes**, but I've heard that the knife holder of speed skates is not strong enough.

In addition to the fact that the speed is fast, the wheels are large, and you can't do fancy styles, what is the difference between speed skates and roller skates, I hope it will be more specific.

Is there a figure-eight when the speed skates brake? Will it be easy to fall?

If you wear speed skates to brush the street, the asphalt road, will it cost a lot of shoes?

I was just groping for the flat flowers by myself, and I didn't know much about the specifics, hoping that a professional would give the little girl a literacy. The main reason is why speed skates are so expensive? Any kind of shoe is one or two thousand!

It would be nice if I could talk about maintenance and so on.

Speed skating shoes pursue lightness and speed, no one will use speed skates to play the limit, the requirement for strength naturally gives way to the requirement for lightness;

Speed skating shoes are a kind of roller skating shoes (roller skates are mainly divided into casual shoes, speed skating shoes, flat shoes, extreme shoes, each type of shoes has its characteristics), the obvious difference between speed skating shoes and other shoes in appearance is in addition to huge wheels and knife holders, and speed skating shoes are without uppers and cuff;

Due to the long knife holder and large wheels, the stability of speed skating shoes is the best among all roller skating shoes, and it is more stable than other shoes in terms of the same braking action, but due to lack of flexibility, high-level fancy brakes are difficult to do;

Brush the street is second only to the brake fee wheel project, if the road is good (the asphalt road is also good and secondary), the wheels are good, not very expensive (the so-called cost shoes, mainly the cost of the wheel), the bearing is the same;

In order to pursue lightness and maintain the right strength, the material will definitely be more expensive, and the sales of speed skates are low, and the inability to produce them on a large scale is also one of the reasons;

As with other roller skates, don't wiper if it's not a ceramic bearing or the technology isn't very good.

For example, we all have experienced toddlerhood, but none of us will give up walking because of multiple falls. That's a kind of sportsmanship.

The Olympic Games, the Continental Games, the National Games, and the sports competitions carried out by individual sports organizations should not belong to the category of non-governmental sports because they are all highly organized and institutionalized sports competitions.

Sports are a cultural activity. Of course, the development process of our physical education from ancient times to the present has changed from simple to perfect, from immaturity to maturity, and in the process of exploration, our country has comprehensively introduced the Soviet sports system, thus realizing some shortcomings, so it is necessary to build its own sports theory system in order to be enriched and developed.

At the same time, sports not only affect a person, but also a team, which is what we commonly call team spirit. Because the sportsmanship of a team is not completed by the strength of one person, it requires everyone to train hard to make a team strong, and at the same time, everyone is working together at the same time, they are constantly giving each other positive energy and cheering for their teammates, because at this time they are a team and are integrated.

In addition to the physical fitness and basketball skills of the students, the use of tactics is also an important factor in determining the outcome of the game. In the course of a basketball game, the two sides fight for a ball, just like the enemy and us attacking a city, whether it is the attacking side or the defending side, we must pay attention to the use of tactics.

The occasional sports behavior of the people belongs to the category of folk sports, such as several young people who love football and meet to play a football match on a football field by chance, then the sports behavior of these young people is folk sports.

It is also necessary to actively organize and carry out football games in schools, and at the same time, we can also innovate the form of basketball games, such as three-on-one basketball, so that students can constantly use and master various tactics in actual combat and strive to achieve better results in basketball games.

Do horizontal bars, pull-ups every day, hang for 30 minutes a day, plus Jordan is also very careful in the diet, eat more food to promote growth, nutrition is not lacking, physical training is enough, plus adolescence growth training, Jordan's height exceeds the family genetic height, height is very important for basketball players, a lot of basketball tactics, height has an advantage in order to operate.

Some scholars believe that the concept of national sports is usually used to describe traditional folk sports activities as opposed to modern sports competitions that are widely spread around the world. [[331 7118]]
