Description

Technical Field

[0001] This utility model belongs to the field of wrench technology, specifically relating to a multi-functional wrench for mechanical repair. Background Technology

[0002] A wrench is an indispensable basic tool in mechanical maintenance, widely used in the installation, disassembly, and repair of various mechanical equipment. It typically consists of a handle, a jaw, and a connecting part, and is usually made of high-strength alloy steel or chrome vanadium steel to ensure its durability and ability to withstand large torques. Depending on the application, wrenches come in a variety of designs.

[0003] Most wrenches on the market today feature a one-piece design. While this structure offers simplicity, it reveals limitations when faced with diverse and complex assembly and disassembly tasks. Especially when dealing with bolts and other connecting parts located at different positions and angles, workers often need to adjust their bodies to accommodate the wrench's fixed operating angle. This means that to assemble or disassemble a single bolt, workers may need to constantly change body postures or find a suitable stance to allow the wrench to accurately contact the bolt head for effective operation. This method is not only time-consuming and laborious, increasing workload, but also potentially creating safety hazards due to frequent body adjustments, thus reducing work efficiency. For workers who perform bolt assembly and disassembly for extended periods, this repetitive body adjustment poses a severe test of their physical strength and endurance. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional wrench for mechanical repair, so as to solve the problem mentioned in the background art that the existing wrenches are limited by their own structure and have many inconveniences in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional wrench for mechanical repair, including a wrench head; a connecting component, one end of which is rotatably connected to the wrench head; and a tail end of the wrench head, which is rotatably connected to the other end of the connecting component. The connecting component consists of a first connecting rod and a second connecting rod, which are rotatably connected. The first connecting rod rotates with the wrench head in one plane, and the second connecting rod rotates with the tail end of the wrench head in another plane. The first connecting rod and the second connecting rod rotate in yet another plane, and the planes of rotation of the first connecting rod and the second connecting rod are perpendicular to the planes of rotation of the wrench head and the first connecting rod, and the second connecting rod and the tail end of the wrench head, thereby achieving omnidirectional rotational adjustment of the entire wrench and satisfying locking and disassembly operations in different directions.

[0006] Preferably, the top end of the first connecting rod extends outward and forms a joint, while the bottom end of the first connecting rod is recessed inward and forms a groove. The joint is connected to the wrench head, and the groove is connected to the second connecting rod.

[0007] Preferably, the top of the second connecting rod has an integral locking pin that is inserted into the slot, and a bolt passes through the connection between the two. Nuts are screwed into both ends of the bolt to limit the connection between the two and prevent separation. The bolt can also rotate around the bolt and is tightened by tightening the nuts on the bolt to ensure locking after angle adjustment. The bottom of the second connecting rod extends downward to form a second connector, which is rotatably connected to the tail of the wrench.

[0008] Preferably, the end face of the wrench head and the end face of the wrench head facing the direction of the connecting component is provided with a groove. The first connector and the second connector are respectively inserted into the corresponding groove. The connection between the first connector and the second connector and the groove is also provided with a bolt for locking and providing rotation. A nut is also provided on the bolt.

[0009] Preferably, the first connector and the second connector are of the same shape and size, thereby facilitating assembly with the wrench head and the tail of the wrench head.

[0010] Preferably, the end of the wrench head is formed with an open plier head, and the tail end of the wrench head is formed with an annular collar. The inner wall of the annular collar is formed with a protrusion. In use, the protrusion is used to abut against the outer surface of the nut, thereby enabling the nut to be rotated.

[0011] Preferably, the widths of the wrench head, connecting rod one, connecting rod two, and the tail of the wrench head are equal; the length of the locking pin is less than the inner depth of the locking groove, thereby ensuring that the normal rotation of the locking pin is not affected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the interlocking structure allows the wrench to be flexibly combined to form various shapes and angles according to actual needs. This feature enables users to easily find the most suitable operating angle when facing complex and varied nut assembly and disassembly tasks, thereby significantly improving work efficiency. More importantly, this interlocking wrench is more convenient to operate. Users only need to simply rotate each surface to the desired position to quickly complete assembly, without any additional tools or complicated operating steps. This intuitive and easy-to-use design not only reduces the difficulty of operation but also greatly enhances the user experience. Attached Figure Description
