Problems solved by technology

Therefore, when opening the pliers, it crosses the straight line in the opposite direction and destroys the self-locking structure of the pliers. However, the existing self-locking destruction is directly realized by external force, and the handle needs a lot of force to open, Ms. Or it is difficult for ordinary men to operate, and in the process of opening, the handle is easy to bounce, which is easy to hurt the hand, and sometimes it can't even hold the pliers and falls, which poses a safety hazard

example 1

[0030] Such as Figure 1 to Figure 5 As shown, a kind of fast forceps comprises a fixed handle 2 and a movable handle 7, the end of the movable handle is hinged with a movable pliers head 5 through a second pin shaft 6, the fixed handle end is connected with a fixed pliers head 4, and the movable pliers head and The fixed handles are hinged and connected with an elastic member 3, and a brace is connected between the movable handle and the fixed handle. Under the action of the elastic member, the movable pliers head has a tendency to rotate relative to the fixed pliers head and open the jaws. Both the movable handle and the fixed handle have groove-shaped cross-sections, and the brace has a sheet structure. One end of the brace is inserted into the movable handle and is hinged to the movable handle through the third pin 8, and the other end of the brace is inserted into the fixed handle. In the handle, the tail end of the fixed handle is screwed with an adjusting screw 1, and ...

example 2

[0034] Such as Figure 6 to Figure 8 As shown, a kind of quick vise is different from Example 1 in that: the unlocking between the control handle and the movable handle is different. The movable handle is a groove structure, the control handle is inserted into the movable handle and hinged by the first pin shaft, the side wall of the connecting groove at the lower end of the movable handle is provided with a button hole 24, the upper end of the control handle is provided with a pin hole 23, and the pin hole is inserted into the There is a stop pin 22, the stop pin is cylindrical, the stop pin is provided with a blind hole, one end of the opening is inserted into the pin hole, and the closed end faces the button hole side, the axial length of the stop pin is less than or equal to the axial length of the pin hole length. A return spring is arranged in the blind hole of the retaining pin, and the return spring is connected to the closed side of the movable handle connection groo...

Abstract

The invention relates to quick vise grip pliers which comprise a fixed handle and a movable handle. A movable plier head is hinged to the end of the movable handle, and the end of the fixed handle isconnected with a fixed plier head. The movable plier head is hinged to the fixed handle and connected with an elastic part, and a stay pin is connected between the movable handle and the fixed handle.The quick vise grip pliers further comprise a control handle hinged to the movable handle and an unlocking button. After the unlocking button is unlocked, the control handle can rotate relative to the movable handle, and a two-linked lever structure is formed by the control handle and the movable handle. At this moment, the movable handle can be made to expand relative to the fixed handle throughsmall force, and the effect of saving labor is achieved.

Description

technical field [0001] The invention relates to a tool pliers, in particular to a fast pliers which can be opened stably and labor-saving. Background technique [0002] Vigorous pliers, English name locking pliers, are mainly used for clamping parts. The jaws can be locked and generate a large clamping force so that the clamped parts will not loosen. The clamped parts are riveted, welded, ground, etc. processing. [0003] The clamping of the pliers is to form a self-locking structure by crossing the position of the straight line formed by the three pivot points on the so-called force line when the movable handle is rotated. Therefore, when opening the pliers, it crosses the straight line in the opposite direction and destroys the self-locking structure of the pliers, but the existing self-locking destruction is directly achieved by external force, and the handle requires a large force to open, Ms. Or it is difficult for ordinary men to operate, and in the process of openin...
