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 tool for loosening bolts, especially an adjustable wrench. The high-strength anti-loosening adjustable wrench is composed of a fixed block, a sliding block, a handle and an adjusting cap. The groove matches the angle of the bolt. There is a push rod inside the handle, and the push rod is connected with the slider. The bottom of the handle is provided with an adjusting cap. The adjusting cap is provided with a bolt. The contact surface between the handle and the bolt is threaded. When rotating, the push rod will be pushed to make the slider rise, otherwise, the slider will fall. When the adjustable wrench is used, rotate the adjusting cap to make the slider rise to match the nut or bolt that needs to be loosened or tightened, and the plate wrench can be operated. , When in use, the groove on the slider and the fixed block matches the angle on the nut, so the deformation degree when the wrench and the nut are engaged is extremely small, which can prevent slipping when the force is applied. The fixed block and the bracket are integrally formed, so they can withstand greater work 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...
