Description

Limiting hand vice

Technical Field

The utility model relates to a hand tool field specifically is a spacing pincers.

Background

A pliers is a hand tool for clamping and fixing a workpiece to be machined or twisting, bending and shearing materials, is generally V-shaped, comprises a handle, a pliers cheek and a pliers mouth, and is generally applied to metal plates, cylinders, wires and the like. The clamping capacity of the pliers acts as a positioning and twisting aid when acting on the screw and the nut. However, since the two side handles need to be kneaded by the hands of the operator for a long time during the clamping of the pliers, if the two side handles are fixed for a long time or twisted, the operator needs to keep the kneading posture in the whole process, which is very laborious, and because some materials have a certain shape due to low hardness, or the surfaces of the materials are provided with threads, a part of the acting force applied by the operator on the handles of the pliers can be used as the kneading force during the twisting process, so that the clamping piece is squeezed, and the strength and the shape of the clamped object are damaged. Therefore, a clamping structure capable of controlling clamping force inconvenience in the use process is needed, so that the force of the pliers is kept unchanged during clamping, and the clamping force of the clamping piece is not too large.

Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

The embodiment of the utility model provides a, according to the spacing pliers that fig. 1-3 show, the electric iron comprises a handle, the handle about divide into long handle 1 and short handle 2, long handle 1 with short handle 2 at the cheek portion amalgamation of pliers, 5 departments of pincers mouth be provided with the frictional force when bellied line is used for increasing the centre gripping, press from both sides tight object.

The handle on be provided with screens mechanism, screens mechanism include ratchet 31, ratchet 31 profile of tooth direction do: the direction from the clamping end of the ratchet bar 31 to the rotating end is along the tooth direction, otherwise, the direction is the clamping direction. One end of the long handle 1 is provided with a positioning hole penetrating through the surface of the long handle 1 and the accommodating groove 11, a positioning shaft 33 is fixed in the positioning hole, the positioning shaft 33 is perpendicular to the accommodating groove 11, the positioning end of the scroll spring 32 is fixed on the positioning shaft 33, and the tightening end of the scroll spring 32 is sleeved with the rotating end of the ratchet rack 31.
