Force releasing mechanism and ratchet wheel clamp with same

Abstract

The invention discloses a force releasing mechanism and a ratchet wheel clamp with same. The force releasing mechanism comprises a first ratchet part, a second ratchet part, a locking part, an actuating part and a restoring part, wherein the first ratchet part with a first ratchet group is fixedly arranged on a first clamping arm of the ratchet wheel clamp; the second ratchet part with a second ratchet group is connected to a second clamping arm through a second shaft and can rotate relative to the second ratchet part; a first hole is formed in the second ratchet part; the locking part passes through the first hole and can rotate and translate in the first hole; the actuating part can perform the first actuating and the second actuating for the locking part in a sequence so as to separate the second racket group and the second racket group which are engaged with each other. With the adoption of the ratchet wheel clamp with the force releasing mechanism, the operation of separating the two engaged ratchet groups can be stably carried out by the two actuating. The force releasing mechanism and the ratchet wheel structure with the force releasing mechanism are simple in structure, simple and easy to process, and convenient to use; a user can smoothly operate, and the force can be saved.

Description

technical field [0001] The invention relates to the field of hand tools, in particular to a force relief mechanism and a ratchet clip with the force relief mechanism. Background technique [0002] Hand tools refer to small tools that are held by hand and act on objects with manpower or other power controlled by people. They are used for manual cutting and auxiliary decoration, and generally have handles for easy portability. Pliers are a class of commonly used hand tools for clamping, fixing workpieces or twisting, bending, and cutting wires. Among them, the pliers used to clamp and fix the workpiece are also called clamps or clamps. [0003] The shape of the clamp or clamp is generally V-shaped, and usually consists of two clamp bodies with mutually symmetrical structures, which are partially overlapped and fixed by riveting. The clamp can be opened and closed flexibly with its riveted connection point as the fulcrum, and its design includes the principle of leverage, so ...

Problems solved by technology

[0006] However, since the actuating part of the clip of the prior art is arranged on the outside of one of its clamp arms, the user needs to press the actuating part when releasing the clamped object. It can be known that the user presses the actuating part When it is necessary to apply a force directed to the other clamp arm on the clamp arm where the actuating part is located, the direction of this force is opposite to the direction of the force exerted by the clamp arm on the hand holding it during the two actuation processes, Therefore, such an operation is not smooth and more laborious.
