Problems solved by technology

[0002] All kinds of wrenches are needed to strengthen or disassemble various mechanical parts. Adjustable wrenches are widely used because of the adjustable engagement with bolts. The precision requirements of the wrench are high, so it is easy to slip. The contact surfaces of the traditional adjustable wrench and the bolt are two opposite surfaces. Slipping or scrapping the bolts, the structure between the slider and the main body of the traditional adjustable wrench is weak, and the root of the slider will break when a large amount of force is applied, so the traditional adjustable wrench is not suitable for use with large torque

Embodiment Construction

[0008] according to figure 1 It can be seen that the adjustable wrench is composed of a fixed block, a bracket, a slide block, a handle and an adjusting cap, the upper end of the handle (1) is provided with a support (2), the top of the support (2) has a fixed block (3), and the slide block (4) It can slide up and down under the limitation of the bracket (2). There is a groove on the contact surface between the fixed block (3) and the slider (4). The angle of the groove matches the angle of the hex nut. The handle ( The lower end of 1) is provided with an adjustment cap (5), and when the adjustment cap is rotated, the slider (4) can be raised through the push rod inside the handle (1).

[0009] according to figure 2 It can be seen that when the adjusting cap (5) is turned, the slider (4) can be lifted up under the push of the push rod (6) inside the handle, and when the slider (4) and the fixed block (3) are closed, the middle The two opposite corners on the nut can be clam...

Abstract

The invention relates to a bolt untightening tool, in particular to an adjustable wrench. The high-strength loosening prevention adjustable wrench comprises a fixed block, a sliding block, a handle, an adjusting cap and the like, wherein grooves are formed in the fixed block and the sliding block; when the wrench is combined to a bolt, the grooves are matched with the bolt angularly; a pushing rod is arranged in the handle and is connecting with the sliding block; the adjusting cap is arranged at the bottom of the handle; a bolt is arranged on the adjusting cap; threads are arranged on a surface, which is in contact with the bolt, of the handle; when the adjusting cap rotates clockwise, the pushing rod can be pushed to enable the sliding block to ascend; when the adjusting cap rotates anticlockwise, the pushing rod can be pushed to enable the sliding block to descend; when the adjustable wrench is used, the adjusting cap rotates to enable the sliding block to ascend, and then the sliding block is matched with a nut or a bolt which requires to be untightened or tightened; and then the wrench moves to operate. When the high-strength loosening prevention adjustable wrench is used, the grooves in the sliding block and the fixed block are matched with the nut angularly, therefore, the degree of deformation is quite small when the wrench is gripped with the nut, and slipping during stress can be prevented; and the fixed block and a support are formed integrally, so that the high-strength loosening prevention adjustable wrench can bear large working force.

Description

Technical field [0001] The invention relates to a tool for loosening bolts, in particular to an adjustable wrench. Background technique [0002] All kinds of wrenches are needed to strengthen or disassemble various mechanical parts. Adjustable wrenches are widely used because of the adjustable engagement with bolts. The precision requirements of the wrench are high, so it is easy to slip. The contact surfaces of the traditional adjustable wrench and the bolt are two opposite surfaces. Slipping or scrapping the bolts. The structure between the slider and the main body of the traditional adjustable wrench is weak. When a large amount of force is applied, the root of the slider will break. Therefore, the traditional adjustable wrench is not suitable for use with large torque. Contents of the invention [0003] In order to solve the shortcomings of the existing adjustable wrench, the invention provides a high-strength anti-loosening adjustable wrench, which is composed of a f...
