Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] Such as figure 1 As shown, the wrench according to the present invention includes: a bayonet assembly 10; a gear set 20; the output gear of the gear set 20 drives the bayonet assembly 10 to rotate; a handle 30; the handle 30 is made of a metal material and drives the gear set 20 The input gear turns. The handle 30 of the present invention drives the bayonet assembly 10 through the gear set 20, that is, the gear set 20 changes the force direction of the conventional adjustable wrench, thereby reducing the space requirement, and is suitable for use in narrow spaces.

[0018] Preferably, the bayonet assembly 10 includes a fixed claw 11 and an adjustable claw 12, the adjustable claw 12 is adjustably arranged on the fixed claw 11, and a bayonet is formed between the fixed claw 11 and the adjustable claw 12 13, that is, adjust the width of the bayonet 1...

Abstract

The invention provides a wrench, comprising: a bayonet assembly; a gear set; an output gear of the gear set drives the bayonet assembly to rotate; a handle is made of metal material and drives an input gear of the gear set to rotate. According to the wrench of the present invention, the handle drives the bayonet assembly through the gear set, that is, the force direction of the conventional adjustable wrench is changed by using the gear set, thereby reducing the space requirement and being suitable for use in narrow spaces.

Description

technical field [0001] The field of fastening tools of the present invention, in particular, relates to a wrench. Background technique [0002] In the prior art, the connecting pipe of the air conditioner needs to be firmly connected with the air conditioner. In some cases, due to the insufficient space reserved for the installation of the air conditioner, the ordinary wrench cannot be installed normally, and the connecting pipe is prone to rupture due to uneven force. , or the connecting pipe is not tightened enough to cause refrigerant leakage. Contents of the invention [0003] The present invention aims to provide a wrench with reduced space requirements. [0004] The invention provides a wrench, comprising: a bayonet assembly; a gear set; an output gear of the gear set drives the bayonet assembly to rotate; a handle is made of metal material and drives an input gear of the gear set to rotate. [0005] Further, the bayonet assembly includes a fixed claw and an adjust...
