[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded fastening bolts or nuts through openings or holes. When the crusher equipment fails or needs to be inspected to check the roller spacing, it is necessary to open the crusher side cover to expose the crusher pulley and inspect the pulley. This process is completed using the corresponding disc roller wrench tool.

[0003] For example, an anti-falling disc roller wrench with application number CN202321896247.7 and authorization announcement date 20240123 includes a handle and a fixing assembly, one end of the handle is provided with a fixing assembly, the fixing assembly includes a fixing seat and a latch bolt, a clamping groove is formed on the fixing seat, a latch bolt is inserted and connected in the clamping groove, the inner wall of the clamping groove is provided with a wear-resistant layer, and the other end of the handle is connected with a telescopic rod. The utility model is an anti-falling disc roller wrench with a fixing assembly, which can fix one end of the wrench on the disc roller under the action of the latch bolt, so that it is convenient for the staff to pull down the disc roller for maintenance, and the wrench is not easy to fall off after being fixed, and it is easy to use. The telescopic rod is provided to adjust the length of the handle, which is convenient for the staff to hold, and the whole wrench has a simple structure and low cost, and can be mass-produced and used. The wear-resistant layer is provided to improve the wear resistance of the connection between the wrench and the disc roller and improve its durability.

[0004] In order to facilitate the use of the disc roller wrench, the handle of the disc roller wrench generally uses a telescopic rod with a telescopic function. However, the telescopic rod is mostly composed of a nested tube body, and the force resistance is poor. The telescopic rod is very easy to break when using the disc roller wrench. Therefore, it is urgent to design an anti-falling disc roller wrench to solve the above problem. Utility Model Content
