Multi-specification pliers with an easily replaceable clamping head

Abstract

A multi-specification pliers with an easily replaceable clamping head includes a handle and a detachable clamping head connected to the handle; the handle comprises a handle insert arranged at the front end; a limit counter bore is processed on the handle insert, with the first bevel on the one side and the second bevel on the other side of the limit counter bore; the clamping head includes the third bevel arranged at the rear end; a limiting boss is processed on the clamping head side; the first bevel is matched to the third one; and the limit counter bore is matched to the limiting boss. The clamping head and handle can be connected quickly and stably for realizing multiple use of the handle, saving materials and costs, and solving the problem of the existing circlip pliers with a replaceable clamping head for not compatible with large-torque pliers.

MODE OF CARRYING OUT THE INVENTION

[0026] The multi-specification pliers with an easily replaceable clamping head in the present invention is introduced in detail combining with the attached figures.

[0027] As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7 and FIG. 8, the multi-specification pliers with an easily replaceable clamping head consists of a handle 1 and a detachable clamping head 2 connected to the handle; the handle 1 comprises a handle insert 1.1 arranged at the front end; a limit counter bore 1.2 is processed on the handle insert 1.1, with the first bevel 1.3 on the one side and the second bevel 1.4 on the other side of the limit counter bore 1.2; the clamping head 2 includes the third bevel 2.1 arranged at the rear end; a limiting boss 2.2 is processed on the clamping head side 2; the first bevel 1.3 is matched to the third one 2.1; and the limit counter bore 1.2 is matched to the limiting boss 2.2; a location hole 1.5 is processed at the handle 1; the location hole 1.5 is matched to the limit counter bore 1.2; a fastener 1.6 is available between the location hole 1.5 and the limit counter bore 1.2; the handle 1 is connected to the handle insert 1.1 by fastener 1.6. The handle 1 is connected to the said handle insert 1.1 by welding. The handle 1 consists of the upper handle 1.7 and the lower handle 1.8; the said upper handle 1.7 and the lower handle 1.8 are flexibly connected by two handle fasteners 1.9. The handle insert 1.1 consists of the upper handle insert 1.1.1 and the lower handle insert 1.1.2; an arc 1.1.3 is processed on the side of the upper handle insert 1.1.1 and a semi-arc 1.10 is processed on the front side of the lower handle 1.8; the clamping head 2 is provided with an independent torsion spring 2.3;

[0028] The clamping head 2 consists of a scissors 2.4, an oblique-mouth component 2.5, a sharp-mouth component 2.6, a wire-cutter 2.7 and a wire stripping pliers 2.8.

[0029] In actual operation, the user only needs to take the required clamping head 2 and insert the front end of the handle 1 to complete clamping head installation; during the insertion, the second bevel 1.4 plays a guiding role, enabling the clamping head 2 to be inserted more quickly. The first bevel 1.3 fits the third bevel 2.1 properly in the handle insert 1.1. Through double limiting of fitting the limit boss 2.2 to the limit counter bore 1.2, the clamping head 2 and handle 1 can be connected quickly and stably.
