Embodiment Construction

[0027] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] It should be noted that relative terms such as "first", "second" and so on may be used to describe various components, but these terms do not limit the components. These terms are only used to distinguish one component from another. For example, without departing from the scope of the present invention, a first component may be called a second component, and a second component may similarly be called a first component. The term "and / or" refers to any one or more combination of related items and described items.

[0029] refer to figure 1 , Figure 5 , figure 1 It is a disassembled view of the structure of the wrench that facilitates the adjustment of the caliber size of the present invention, Figure 5 It is a partially enlarged schematic diagram of a wrench for adjusting the diameter of the present invent...

Abstract

The invention discloses a caliber adjustable wrench. The caliber adjustable wrench comprises a first rack provided with a twentieth locating column, a first connecting rod and a second rack fixed to the first rack. A caliber adjusting mechanism and a trigger are arranged between the first rack and the second rack. One end of the first connecting rod is connected with the trigger. The other end ofthe first connecting rod is connected with the caliber adjusting mechanism. The trigger is provided with a twentieth locating hole. The twentieth locating column is inlaid into the twentieth locatinghole. After being hooked and pressed, the trigger rotates around the twentieth locating column to drive the first connecting rod to push the caliber adjusting mechanism to adjust the caliber. The technical problems that the cost is increased and the labor force is wasted due to the fact that rotation between a chuck and a rack has quite high precision requirements in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of wrench tools, and in particular relates to a wrench which is convenient for adjusting the size of the caliber. Background technique [0002] At present, most wrenches can adjust the caliber size. For example, the patent application number is 201711191984.6, and the application name is a wrench with adjustable caliber. The disclosed wrench structure can adjust the caliber of the caliber adjustment mechanism by rotating the chuck. In fact, the chuck rotation has extremely high requirements for the accuracy of the curved groove and positioning parts, and the insufficient precision will affect the chuck rotation, which greatly increases the production cost, and the wrench structure utilizes the relative movement between a frame and the chuck to realize the accuracy of the caliber. Driven by the adjustment mechanism, the actual rotation of the chuck needs to waste more power of the user, and there is a problem...
