Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0030] like figure 1 , figure 2 As shown, the fastener loosening and tightening tool of the present invention includes a handle and a sleeve locking belt 4, the sleeve locking belt 4 is sleeved to lock the fastener 3, and the sleeve locking belt 4 is driven by the handle. And loosen or tighten the fastener 3 .

[0031] In the present invention, the handle specifically includes a support handle 1 and a locking handle 2, and the end 11 of the support handle 1 and the end 21 of the locking handle 2 are pivotally connected together through the shaft 10, so that the support handle 1 and the locking handle 2 are relatively rotatable relative to the shaft 10 .

[0032] One end 41 of the lock belt 4 is connected and fixed to the front end 12 of the support handle 1 , and the other ...

Abstract

The invention discloses a fastener unscrewing and tightening tool. The tool comprises a handle and a locking belt, the locking belt locks a fastener, and the handle drives the locking belt to unscrewor tighten the fastener. The handle comprises a supporting handle body and a locking handle body, and the tail end of the supporting handle body is pivoted to the tail end of the locking handle body.One end of the locking belt is connected and fixed to the front end of the supporting handle body, and the other end of the locking belt bypasses the fastener, penetrates through the portion between the front end of the supporting handle body and the front end of the locking handle body and is clamped and fixed by the front end of the supporting handle body and the front end of the locking handlebody. In the fastener unscrewing and tightening tool, by means of the strong clamping force between the front end of the supporting handle body and the front end of the locking handle body, the locking belt is pressed on the surface of the fastener so that the locking belt can be completely prevented from moving relative to the fastener, and smooth detachment of the fastener is facilitated.

Description

technical field [0001] The present invention relates to a tool, in particular to a fastener loosening and tightening tool. Background technique [0002] Fasteners are common connection functional parts in production and life. [0003] Fasteners may include hex bolts, round head bolts, and the like. For fasteners such as hexagonal bolts, the corresponding hexagonal wrench can be used to tighten or loosen, while for round head bolts or similar round head fasteners, a special wrench is required for disassembly. [0004] Since the outer contour of the round head fastener itself is circular, it is very easy to slide relative to the tool during the disassembly operation, thereby affecting the smooth progress of the disassembly work. SUMMARY OF THE INVENTION [0005] Aiming at the disadvantages of the prior art, the present invention provides a fastener loosening and tightening tool. [0006] The fastener loosening and tightening tool of the present invention includes a handle...
