Problems solved by technology

In the field of electric power, it is often encountered that thicker cables are cut. If the existing bolt cutters with shorter handles are used for cutting, it is time-consuming and laborious, and it is not conducive to operation. For some cables in higher places Clipping cannot be achieved, the cable needs to be placed in a lower place to achieve clipping

Embodiment 1

[0020] Such as Figure 1-2 As shown, the present invention includes a movable knife edge 1, a fixed knife edge 2 installed on the pliers handle 3, a pliers handle 3, a handle 4 and a pull rod 5, and the pull rod 5 is connected between the pliers handle 3 and the handle 4, and the pull rod 5 can Completely extend into or out of the handle 4; one end of the movable knife edge 1 is suspended in the air, and the other end is movably connected with the end of the fixed knife edge 2 through a pin shaft. When it is necessary to cut a thicker cable or the cable is located at a higher position, the pull rod can be pulled out from the inside of the handle to an appropriate length to increase the length of the power arm composed of the handle and the pull rod. With a small external force, the cutting operation of thicker cables can be realized, which is more labor-saving than ordinary bolt cutters.

Embodiment 2

[0022] In this embodiment, on the basis of Embodiment 1, the preferred specific structure is as follows: two parallel pull rods 5 are installed on the bottom of the pincer handle 3, and each pull rod 5 is connected to a handle 4. Two pull rods are set, which is more conducive to the simultaneous operation of both hands during the force application operation, and the operation is more convenient.

Embodiment 3

[0024] In this embodiment, on the basis of any one of the above embodiments, the preferred specific structure is as follows: the surface of the handle 4 is set as a concave arc surface, and the surface of the handle 4 is set with uniform stripes. Let the handle fit closely with the hand, increasing the comfort of hand feeling during use. In order to increase the friction force on the surface of the handle to prevent slipping off during use, which is not conducive to the wire cutting operation of the cable.

Abstract

The invention discloses a pair of wire clippers with the adjustable length. The wire clippers comprise a movable cutting edge (1), a fixed cutting edge (2), a clipper handle (3), a handle (4) and a pull rod (5), wherein the fixed cutting edge (2) is arranged on the clipper handle (3), the pulling rod (5) is connected between the clipper handle (3) and the handle (4) and can completely extend into or extend out of the handle (4), one end of the movable cutting edge (1) is suspended, and the other end of the movable cutting edge (1) is movably connected with the end part of the fixed cutting edge (2) through a pin shaft. Through the structure, the wire clippers have the advantages that the length between the handle and the pulling rod is adjustable on the basis of a pair of ordinary wire clippers, when the wire clippers are used for cutting thick cables, the total length of the handle and the pulling rod is increased, and more labor is saved.

Description

technical field [0001] The present invention relates to tools for use in electrical operations, and in particular to adjustable length bolt cutters. Background technique [0002] Bolt cutters are widely used in hardware, construction and other industries to cut iron wires, steel bars and other objects. Traditional bolt cutters are mainly composed of a pair of cutter heads and a pair of handles. The cutter heads and handles are connected to each other through connecting pins. Hinged, the connecting plate and the connecting plate pin shaft are movably connected together with the two cutter heads, and the two handles are also hinged to each other by the handle pin. However, the length of the handles used now is fixed and the length of the handles is designed to be relatively short. At the same time, the length cannot be adjusted. For some thicker cables that need to be cut in the power field, it is more laborious to cut. Through the principle of leverage, we know that to make ...
