Problems solved by technology

There are many types of wrenches, which can be divided into double-ended wrenches, dual-purpose wrenches, live-end wrenches, etc. The openings of these wrenches usually pass through up and down for the convenience of processing, so that the head of the wrench must be held by hand when tightening bolts or nuts. It is on the same plane as the bolt head or nut. When people use the wrench, if they accidentally move it along the threaded axis, it may cause the wrench to break away from the bolt head or nut, so that people have to reposition the wrench, which is very troublesome.
Moreover, when people use a wrench to remove screws or nuts, when the bolts or nuts are suddenly separated from the thread, the force is suddenly changed, and the bolts or nuts are very easy to fall.

Embodiment Construction

[0011] Below in conjunction with embodiment the present invention is further described:

[0012] like figure 1 As shown in the embodiment, the anti-jamming wrench includes a wrench body 1 and a clamping plate 2; the wrench head part of the wrench body 1 is designed with a bayonet structure 11, and the bayonet structure 11 is designed with an arc edge , the clamping plate 2 is designed with a semicircular groove 21, and the clamping plate 2 is attached to the wrench head part of the wrench; the semicircular groove 21 of the clamping plate 2 and the bayonet structure 11 The arcs have the same center, and the opening directions of the two are corresponding. The wrench body 1 is a double-ended wrench structure or a dual-purpose wrench structure or an adjustable wrench structure. In this embodiment, the wrench body 1 adopts a double-ended wrench structure, and both ends of the wrench are designed with clamping plate 2 structures.

[0013] The anti-jamming wrench is mainly used f...

Abstract

The invention provides a fall-prevention wrench which comprises a wrench body and a clamping plate. The head part of the wrench body is designed to be provided with a bayonet structure. An arc side is designed to be arranged on the bayonet structure. A semi-circle groove is designed to be formed in the clamping plate. The clamping plate adheres to the head part of the wrench body. The semi-circle groove of the clamping plate is concentric with the arc of the bayonet structure. The directions of the openings of the clamping plate and the bayonet structure correspond to each other. The fall-prevention wrench is simple in structure, convenient to use, not prone to falling when being used for screwing, higher in assembling efficiency and capable of being supported by the clamping plate when a bolt or a nut is detached and preventing the bolt or the nut from falling.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to an anti-jamming wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. There are many types of wrenches, which can be divided into double-ended wrenches, dual-purpose wrenches, live-end wrenches, etc. The openings of these wrenches usually pass through up and down for the convenience of processing, so that the head of the wrench must be held by hand when tightening bolts or nuts. It is on the same plane as the bolt head or the nut. When people use the wrench, if they accidentally move alo...
