Description

Technical Field

[0001] This utility model relates to the field of wrench technology, specifically to an electric wrench. Background Technology

[0002] An electric wrench is a wrench powered by an electric source or battery. It is a tool for tightening high-strength bolts, hence it is also called a high-strength bolt gun. It is mainly divided into impact wrenches, torque shear wrenches, torque-controlled wrenches, angle wrenches, and corner wrenches.

[0003] Existing electric wrenches have a one-piece wrench head, which is a consumable part. The hexagonal head is prone to wear and tear and is easily scrapped. Moreover, since this wrench head is a non-standard part, it is not available on the market and the mail order price from manufacturers is expensive. If it is processed by oneself, it is labor-intensive and material-intensive. Therefore, we propose an electric wrench that changes the connecting head and connecting rod from a one-piece structure to a detachable structure, which facilitates subsequent maintenance and replacement operations. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide an electric wrench in which the positioning hole cooperates with the positioning bolt and the locking hole to fix the connecting rod inside the connecting head, changing the connecting head and the connecting rod from an integral structure to a detachable structure, which facilitates subsequent maintenance and replacement operations. In addition, the positioning pin and the positioning groove are engaged to connect the corrugated pipe between the mounting head and the connecting head, providing full protection for the connecting rod and effectively preventing the connecting rod from being contaminated by foreign objects.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An electric wrench comprising:

[0008] The wrench holder serves as a connecting base, and a connecting seat is connected to the end of the wrench holder;

[0009] The connecting component is attached to the connecting seat and serves as the connecting middle part to connect the wrench holder and the connecting rod component;

[0010] The connecting component includes a connector that connects to the connector seat, the connector having a positioning hole and a positioning bolt connected to the corresponding positioning hole.

[0011] Protective components, connected to connecting components, provide auxiliary protection for the connecting rod components;

[0012] The connecting rod assembly connects to the connecting assembly and acts as a power output shaft to drive the mounting head to rotate.

[0013] In a preferred embodiment of the electric wrench described in this utility model, the protective component includes a bellows connected to the connecting head, and the other end of the bellows is connected to the connecting rod component.

[0014] In a preferred embodiment of the electric wrench described in this utility model, the outer side of the connector is integrally formed with two sets of positioning posts, and the outer side of the corrugated tube is provided with a positioning groove that engages with the positioning posts.

[0015] In a preferred embodiment of the electric wrench described in this utility model, the connecting rod component includes a connecting rod connected to a connecting head, the connecting rod having multiple sets of locking holes, and the front end of the connecting rod being connected to a mounting head.

[0016] In a preferred embodiment of the electric wrench described in this utility model, multiple sets of locking holes are arranged linearly and equidistantly from left to right along the outer side of the connecting rod, and the locking holes are adapted to the positioning holes and positioning bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The positioning hole, positioning bolt, and locking hole mate to fix the connecting rod inside the connector, transforming the connector and connecting rod from a single integrated structure into a detachable structure. This facilitates subsequent maintenance and replacement. Furthermore, the positioning pin and positioning groove engage to connect the bellows between the mounting head and the connector, providing full protection for the connecting rod and effectively preventing contamination from foreign objects. Additionally, adjusting the positions of the locking hole and positioning hole allows for easy modification of the connecting rod's extension length, facilitating subsequent operation.
