[0029] Specifically, as shown in Figure 1 , 2 , the wrench tool of the present embodiment mainly cooperates with the dismounting groove on the oil return filter core through the dismounting tooth, so as to rotate and dismount the filter core cover. As shown in Figure 3 , 4 , the dismounting tooth is designed to be of a cross-shaped structure, which is adapted to the distribution of the dismounting groove, can be engaged in the dismounting groove and fixed. Among them, the size relationship between the tooth width of the dismounting tooth and the groove width of the dismounting groove can ensure that the dismounting tooth can be smoothly inserted into the dismounting groove and rotate the filter core cover. As shown in Figure 3As shown, the oil return filter element includes the filter element body 7 and the upper filter element cover 5, and the outer end face of the filter element cover is provided with a disassembly groove 6, and the upper end of the filter element body is externally fixed with an oil return interface 4, which is in communication with the internal core body and is used for flowing out filtered oil. Meanwhile, one side of the upper part of the filter element body is also provided with an electric signal acquisition point, which adopts a sensor structure and functions to monitor the pressure change in real time, judge whether the filter element is blocked, and remind timely replacement of the filter element. Figure 1 As shown, the center of the disassembly tooth is a hollow structure.

[0030] Specifically, the wrench tool is held by the wrench handle, and the disassembly tooth is fixed on the wrench handle through the bottom plate tooth seat. As shown, Figure 1 、 2 As shown, the bottom plate tooth seat is fixedly arranged at the middle part of the wrench handle, so that the disassembly tooth is installed at the middle of the length direction of the wrench handle, the balance and uniform force application during use can be maintained, and the installation and disassembly efficiency is improved. In the embodiment, the wrench handle and the bottom plate tooth seat are connected by welding, and the bottom plate tooth seat and the disassembly tooth are connected by welding. The disassembly tooth is made of Q355B steel, and the material of the bottom plate tooth seat is Q355B steel.
