Abstract

The utility model provides a pair of tree clamping pliers. The tree clamping pliers comprise a plier body, a clamping portion is arranged at the front end of the plier body, and is composed of two semicircular iron rings, inward sawtooth-shaped cutting edges are arranged at the front ends of the two iron rings respectively, the rear ends of the two iron rings are connected together through a screw to be fixed in the plier body, a groove is formed in the position, corresponding to the screw, on the plier body, the screw can move up and down in the groove, the plier body is formed by welding two thin cylinders to one end of a thick cylinder, the clamping portion is arranged at the thick cylinder end of the plier body, a hook is arranged in one thin cylinder of the plier body, and the front ends of the hooks are connected to the screw. An insulation rope and an insulation rod are connected to the tail end of the annular clamping pliers, ground working is achieved, security risks are reduced, meanwhile, power supply reliability is improved, and according to the tree clamping pliers, time and labor are saved, and tree obstacle cleaning efficiency is improved.

Description

A kind of folder tree pincers

Technical field

The utility model relates to tree barrier cleaning tool, relates in particular to a kind of for clearing up the folder tree pincers of roadside trees.

Background technology

In the erection process of power transmission line field, often need to clear up the trees of its periphery, in case branch trolley wire affects power transmission efficiency and security incident occurs.Existing tree barrier cleaning tool is mainly handsaw and chain saw, while using this instrument, easily cause trees to fall on wire, this just needs staff in circuit scale removal process, first climbing is entangled trunk to trees higher position with rope, then the opposite direction of its guiding line is pulled, then cut down.

This process, the personnel that easily cause fall, and have potential safety hazard; Meanwhile, for live wire, must trees be dialled and be left with insulating tool, waste time and energy.

Summary of the invention

In order to solve, power circuit screen of trees scale removal process wastes time and energy, the problem of poor stability, the utility model proposes a kind of for clearing up the folder tree pincers of screen of trees.

For this reason, the technical solution of the utility model is: a kind of folder tree pincers, comprise caliper, front end at caliper is provided with sandwich part, described sandwich part is comprised of two semicircle annular iron rings, at the front end of two iron rings, is respectively equipped with inside zigzag cutting edge, and the rear end of two iron rings is linked together and is fixed in caliper by a screw, it is characterized in that: on caliper, be provided with groove with the correspondence position of screw, described screw can move up and down in groove; Described caliper is that one end of a thick cylinder is welded with two thin cylinders, and described sandwich part is positioned at thick cylinder one end of caliper; In a thin cylinder of described caliper, be provided with a hook, the front end of this hook is connected on above-mentioned screw.

While using this instrument, on the hook of caliper, bind an insulating cord, in another thin cylinder of caliper, insert insulating bar; Then the branch position that needs cleaning sent into these pincers by hand-held insulating bar, allows two annulus of sandwich part entangle this branch; Pull the insulating cord on hook, the screw that is connected in hook front end is moved down, thereby drive sandwich part to move down, the cutting edge closure of two annulus front ends is intersected, cut off branch, reach the object of cleaning screen of trees.

Beneficial effect:

The utility model, connects insulating cord and insulating bar by the end at an annular clamp, realizes Ground Operation, during the higher screen of trees of cleaning, need not climb in high-altitude, has reduced security risk; Meanwhile, can in the situation that circuit does not have a power failure, clear up the trees nearer apart from electric wire, avoid having a power failure, improve power supply reliability.Use this instrument, time saving and energy saving, improved screen of trees cleaning efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Number in the figure is: 1, caliper; 2, sandwich part; 3, zigzag cutting edge; 4, screw; 5, groove; 6, hook.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, a kind of folder tree pincers, comprise caliper 1, at the front end of caliper 1, be provided with sandwich part 2, described sandwich part 2 is comprised of two semicircle annular iron rings, the rear end that is respectively equipped with inside 3, two iron rings of zigzag cutting edge at the front end of two iron rings is linked together and is fixed in caliper 1 by a screw 4; On caliper 1, be provided with groove 5 with the correspondence position of screw 4, described screw 4 can move up and down in groove 5; Described caliper 1 is that one end of a thick cylinder is welded with two thin cylinders, and described sandwich part 2 is positioned at thick cylinder one end of caliper 1; In a thin cylinder of described caliper 1 lower end, be provided with a hook 6, the front end of this hook 6 is passed through to a chain connection on above-mentioned screw 4, the tail end of hook is used for fastening insulating cord.

Claims
