AI Technical Summary

Problems solved by technology

Existing wrenches are generally only suitable for one type of nut. If there are different types of nuts, you need to use wrenches of different specifications to work, which makes the operation cumbersome and inconvenient to carry.
The length of existing wrenches is generally fixed due to design defects. During use, it is difficult to unscrew tighter bolts, screws, nuts, etc. because the lever arm is not long enough. The tail end is sleeved with an auxiliary rod that can increase the lever arm of the wrench, but it is generally difficult to easily find a suitable auxiliary rod during use. Therefore, the existing wrench device brings a lot of inconvenience to the user

Abstract

The invention discloses a wrench device which comprises a wrench body. A wrench head is arranged at one end of the wrench body. An opening capable of clamping a bolt or a nut is formed in one end of the wrench head. The wrench device is characterized in that an adjusting mechanism for adjusting the size of an opening inner cavity is arranged in the wrench body, and a handle mechanism capable of adjusting the length is arranged at the other end of the wrench body. The wrench device which is simple in structure, can adjust the size of the opening inner cavity to adapt to the bolts, nuts and the like of different sizes, and can adjust the length is provided for overcoming the defects in the prior art.

Description

technical field [0001] The invention relates to a wrench device. 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 an opening or a sleeve hole for clamping a bolt or a nut at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction to twist the bolt or nut. Existing wrenches are generally only suitable for one type of nut. If there are different types of nuts, wrenches of different specifications are required to work, which makes the operation cumbersome and inconvenient to carry. The length of existing wrenches is generally fixed due to design defects. During use, it is difficult to unscrew tighter bolts, screws, nuts, etc. because the lever arm is not long enough. The tail end is sle...
