Clamping force limited clamp

Abstract

The invention provides a clamping force limited clamp. The clamping force limited clamp comprises a jaw, a knife edge, a force limiting handle and an auxiliary handle, wherein the force limiting handle and the auxiliary handle are of symmetrical structures and are respectively integrally connected with the jaw and the knife edge by a hinging shaft; the force limiting handle comprises a handle tail and a handle head of which the inner side surfaces are hinged to each other; magnetic blocks of which the opposite poles are opposite to each other are respectively assembled on the contact surfaces of the handle tail and the handle head; the contact surfaces of the handle tail and the handle head are also connected in a tensioned manner by a spring. The clamp is similar with a common clamp in structure and can be held by a palm; if a holding force applied to the handle tail is too large, the handle tail and the handle head can rotate along a hinged position, so that the close contact surfaces of the handle tail and the handle head are separated, and thus too large force is prevented from being applied to the clamp during work so as not to cause damage to the jaw or the knife edge.

Description

Technical field [0001] The invention belongs to the technical field of hardware tools, and in particular relates to a type clamp with limited clamping force. Background technique [0002] Pliers are a hand tool used to clamp and fix workpieces or to twist, bend, and cut wires. The shape of the pliers is V-shaped, and usually includes three parts: handle, pliers jaw and pliers mouth. When using the pliers, the principle of leverage can be used to exert a clamping force on the object that is much greater than the force of the palm of the hand. This can facilitate people to carry out various operations on clamping objects, but in real production and life, many objects or parts cannot be clamped with a large clamping force, otherwise the objects will be easily damaged. In addition, when using pliers When the knife edge cuts the metal wire, the strength of the metal wire that can be cut by the knife edge corresponding to different materials is also different. If the cut metal ...

Problems solved by technology

This can facilitate people to carry out various operations on clamping objects, but in real production and life, many objects or parts cannot be clamped with a large clamping force, otherwise it is easy to clamp the object. In addition, when using pliers When the knife edge cuts the metal wire, the strength of the metal wire that can be cut by the knife edge corresponding to different materials is also different.

If the cut metal wire is too hard, it is easy to cause damage to the cutting edge of the pliers during the forcible pinching operation
