Embodiment Construction

[0099] figure 1 and figure 2 It shows the configuration of the first embodiment of the ratchet clamp proposed by the present invention including the clamp mechanism and the ratchet mechanism. Wherein, the clamp mechanism 10 is connected with the first clamp arm 11 and the second clamp arm 12 through the connecting shaft 13, and the connecting sleeve is provided with a torsion spring 131, and the two ends of the torsion spring 131 are respectively pressed against the first clamp arm 11 and The second clamping arm 12 , and the first clamping arm 11 and the second clamping arm 12 control the opening or closing of the jaws 14 with the connecting shaft 13 as the rotation center. Specifically, when the first clamp arm 11 and the second clamp arm 12 are operated to be relatively close together, the jaw 14 can be gradually reduced, and the torsion spring 131 can be elastically deformed under force, and then the position of the jaw 14 can be fixed by the ratchet mechanism. , so that...

Abstract

The invention discloses a ratchet wheel clamp. The ratchet wheel clamp comprises that a first clamping arm and a second clamping arm are mutually pivoted to be opened or closed relative to each otherthrough a connecting shaft, and a ratchet component, a swinging component and a control component are arranged between the first clamping arm and the second clamping arm; the ratchet component is provided with a plurality of first ratchets and a plurality of second ratchets which are arranged side by side and are staggered with one another; the swinging component and the ratchet component are relatively far away from or close to each other by taking the connecting shaft as a rotating axis; a clamping part of the control component is provided with at least a first pawl and at least a second pawl, a pulling part of the control component is used for shifting the clamping part to move; when the clamping part moves to a meshing position, the first pawl and the second pawl are correspondingly meshed with the corresponding the first ratchets and the second ratchets; and when the clamping part moves to a release position, the first pawl and the second pawl are correspondingly far away from thecorresponding first ratchets and the second ratchets. Through the design of ratchets which is arranged in a staggered mode, the ratchet shape cannot be reduced, so that the structural strength is increased, and the overall clamping force is greatly enhanced.

Description

technical field [0001] The invention relates to the field of hand tools, in particular to a ratchet mechanism for misalignment locking and release and a ratchet clip. 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 carrying. Pliers are a type of commonly used hand tools 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 pliers or clips is generally V-shaped, and usually consists of two clips with symmetrical structures and shapes, which are partially overlapped and fixed by riveting. The clamp can be flexibly opened and closed with its riveted connection point as the fulcrum. Its design includes the principle of leverage, so that a...
