Technical Field

The invention relates to the technical field of bolt clippers, in particular to a mechanical bolt clipper.

Background

The wire clipper is a tool for cutting off wires. Wire clippers are tools used to cut thick wires. Generally, there are insulated handle wire clippers, iron handle wire clippers and also a pipe handle wire clipper. Among them, electricians often use insulated handle bolt clippers, and the working voltage is 1000V, and the bolt clippers can be used for live working of wires below 380V of low-voltage electrical equipment. Wire clippers are commonly used to cut wires and cables.

The existing mechanical bolt clippers are heavy and complex in structure, labor-consuming to use and prone to abrasion of a knife edge, and after abrasion, the bolt clippers can only be replaced integrally, so that resources are wasted.

Disclosure of Invention

Aiming at the problems of the existing mechanical bolt clippers, the invention provides the mechanical bolt clipper which realizes the purposes of replaceable shearing blades, simple structure, convenient operation and labor saving.

The technical scheme provided by the invention is as follows: the utility model provides a mechanical bolt clipper, the bolt clipper contains the arm of force of two middle parts cross rotation connection, arm of force one end is insulating handle, and the other end is the cut, the shearing blade of cut is detachable connection, be equipped with helping hand spring between the insulating handle.

Furthermore, the shearing openings are rhombic, the shearing blades are inserted into the shearing opening positions of the force arm, and the two shearing blades are matched with each other.

Furthermore, the shearing blade is a blade matched with the shape of the shearing opening, notches are formed in two surfaces of the shearing blade, and a clamping boss is arranged on one side of the shearing blade.

Furthermore, the screens boss is wider than shear blade, the screens boss with shear blade be the cross section that integrated into one piece made for T type structure.

Furthermore, the power-assisted spring is arranged at one end of the insulating handle and close to the middle part of the force arm, and the power-assisted spring is elastically connected with the insulating handle to close the insulating handle and the shearing opening.

Further, the insulating handle is sleeved with the groove type insulating sheath.

Compared with the prior art, the invention has the advantages that: the shearing blade inserted in the shearing opening is designed, and can be replaced in time after the cutting edge is worn, so that the waste of resources is reduced. And the power-assisted spring promotes the insulating handle to be closed, so that the shearing opening is closed, and the operation is more labor-saving when the mechanical bolt cutter is used for shearing.
