What is the best vice for electricians

Vice, also known as wire pliers, pinyin: lǎo hǔ qián, English plier, like a vice, translates as a pair of pliers. Explanation: Hand tools with bladed jaws, mostly used to pick up nails or clip nails and wires.

Hardness requirements. Pliers HRC42-48, rivets HRC45-48, cutting edge HRC54-62, head HRC44-48

Use. The tooth mouth can be used to tighten or loosen the nut;

The knife edge can be used to cut the rubber or plastic insulation layer of soft wires, and can also be used to cut wires and wires;

The guillotine can be used to cut hard metal wires such as wires and steel wires;

The insulating plastic pipe of the pliers has a voltage resistance of more than 500V, with which it can cut wires with electricity.

It is mostly used to pick up nails or clip nails and wires.

Detect good and bad. Detecting the quality of a wire cutter is mainly from the following aspects:

1) Hold the handle tightly, facing the bright light, the cutting edge shall not transmit light, otherwise it will be unqualified, and the gap shall not be larger.

2) The angle of the pliers shall not be less than 22°

3) The gills must not be jammed, and the hard steel wire can be cut.

4) The tail rubber sleeve should not be significantly loose.

5) The surface plating layer can not have obvious scratches.

Precautions. 1) It is strictly forbidden to use ordinary pliers to work with electricity, please use telecommunication tongs for live work;

2) Protective measures should be taken when cutting the tight metal wire to prevent the cut metal wire from being injured;

3) The wire cutter cannot be used as a percussion tool.

The best vise for electricians is not what the brand is, but the quality and use are different and the brand is different.

Stanley, Star, it's all good, but it's expensive.

Xingma's is good** and cheap, and the foreign brand is easy to use** high.

You're all too amateurish for Kennypak to know?

Leverage principle. Because the moments at both ends of the fulcrum are equal, and the moment = force * the vertical distance from the force to the fulcrum. So vise.

The handle is long and the mouth is short, that is, the clamp wire is close to the fulcrum, and the force is far away from the fulcrum, which is a labor-saving lever

The vice uses the lever principle, where the hand holds the arm more than the place where the object is clamped. It is a labor-saving lever.

Hope, thank you.

The pliers part of the vise increases friction by reducing the contact area and improves the bite force. The handle part of the vise uses the lever principle to lengthen the handle to reduce the grip force required for use.

The shape of a vise is similar to that of a pair of scissors, and it is a combination of the lever principle and the shear force.

The lever principle, the screw in the middle of the pliers is the fulcrum, and the grip is the force arm.

The principle of a vice is actually a lever primordial. The handle is longer, so the vise is a low-effort lever.

The lever principle, the power arm is larger than the resistance arm.

The principle of leverage, all pliers are based on this principle.

A vise is the most common kind of tool for home use, generally 6-8 inches. The wire cutter is a special tool for cutting steel wire in the factory, which is relatively large, generally 14-40 inches, see the following two **.
