Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a split multi-purpose wrench. Background Art

[0002] A wrench is a commonly used installation and disassembly tool, which mainly uses the lever principle to twist bolts, screws, nuts and other threaded fasteners. The working principle of the wrench is based on the lever principle. By applying an external force on the handle, the bolt or nut is moved along the thread rotation direction, so as to achieve the effect of tightening or loosening. When in use, the opening or socket hole of the wrench needs to be aligned with the head of the bolt or nut, and then force is applied in the correct direction.

[0003] The use of a manual wrench is relatively simple. Just select the appropriate model and apply force. When in use, select a wrench of the corresponding size according to the size of the bolt or nut to be operated, ensure that the size of the wrench matches that of the bolt or nut, hold the handle part of the wrench with the hand, firmly grasp it with the thumb and other fingers, and maintain a stable holding force. Apply force through the strength of the arm or other auxiliary tools (such as an extension rod). Tighten the bolt in the clockwise direction or loosen the bolt in the counterclockwise direction. Pay attention not to use too much force to avoid damaging the bolt or the wrench.

[0004] However, in the prior art, although the wrench for sink and bathroom is equipped with two clips of different sizes, these two sizes may still not cover all possible pipe diameters, resulting in poor clamping effect or inability to clamp for some pipes with special sizes or unconventional designs. The design of the clip may not be stable enough. Especially when dealing with pipes with wet, slippery or irregular surfaces, it is easy to slip or loosen, affecting work efficiency and safety. Summary of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a split multi-purpose wrench to solve the technical problems that the clip size of the existing wrench for sink and bathroom is limited and difficult to cover all pipe diameters, resulting in poor clamping effect on pipes with special sizes; and the clip design has insufficient stability and is easy to slip when dealing with pipes with wet, slippery or irregular surfaces, affecting work efficiency and safety.

[0016] The present utility model is further configured such that an activity groove for cooperating with the main body is provided in the activity block.

[0017] By adopting the above technical solution, the provided activity groove is beneficial for the activity block to cooperate with the button, enabling the activity block to slide flexibly on the outer side of the main body, thereby adjusting the sizes of the movable jaw and the fixed jaw.

[0018] The present utility model is further configured such that a convex block is fixedly installed in the activity groove, and a sliding groove for cooperating with the convex block is provided on the outer side of the main body.

[0019] By adopting the above technical solution, the mutual cooperation between the provided convex block and the sliding groove is beneficial for the slider to slide smoothly on the outer side of the main body.

[0020] In summary, the present utility model mainly has the following beneficial effects:

[0021] The present utility model makes the locking block tilt up and not contact the first caliper by pressing the button, and then slides the activity block according to the size of the pipe sleeve. When the activity block slides downward, the movable jaw will also move accordingly, thereby achieving the effect of flexibly adjusting the distance between the movable jaw and the fixed jaw, so as to adjust the size of the jaw according to the actual situation. After the jaw clamps the pipe sleeve, rotate the main body to achieve the effect of tightening or loosening. And through the mutual cooperation between the first mounting head, the second mounting head and the third mounting head, it is beneficial for the wrench to have a certain flexibility, enabling it to adapt to different sizes and types of pipe connection tasks, thereby realizing its versatility and improving the practicality and flexibility of the entire split multi-purpose wrench;
