The chain 4 is used to cooperate with the clamping block 3 to lock the oil filter 9.

[0026] In this embodiment, the oil filter removal and installation tool adjusts the locking length of the chain 4 through the cooperation of the locking device 5 and the adjusting device 6, and adjusts the position of the clamping block 3 through the cooperation of the adjusting rod 2 and the connecting seat 1. Therefore, when the oil filter removal and installation tool is fitted over the oil filter 9, the chain 4 and the clamping block 3 can fit against the outside of the oil filter 9, thus achieving the effect of locking the oil filter 9 with the cooperation of the chain 4 and the clamping block 3. After the oil filter 9 is locked, only... Centered on the oil filter 9, the oil filter removal and installation tool can be used to remove and install the oil filter 9 by rotating it. The operation is simple and convenient, solving the problem of the oil filter 9 being difficult to remove and install, and greatly improving the removal and installation efficiency of the oil filter 9. At the same time, since the locking length of the chain 4 and the position of the clamping block 3 can be adjusted, it is possible to lock and remove oil filters 9 of different sizes, thus greatly improving the scope of use and utilization rate of the oil filter removal and installation tool.

[0027] In this embodiment, the clamping block 3 is arc-shaped to fit the oil filter 9, and an anti-slip structure 31 is provided on the clamping side of the clamping block 3. By setting the clamping block 3 to an arc shape and providing the anti-slip structure 31 on the clamping side of the clamping block 3, the friction between the clamping block 3 and the oil filter 9 is increased, preventing the oil filter 9 from slipping during the disassembly and assembly process, thereby improving the disassembly and assembly effect.

[0028] In this embodiment, the anti-slip structure 31 is preferably a plurality of convex ridges spaced apart. Of course, a structure with multiple convex dots can also be used. The choice is made according to actual needs, and this embodiment does not limit this.

[0029] In order to support the clamping block 3 and the adjusting rod 2 and reduce the coefficient of mechanical load friction between them during rotation, a first bearing 8 is provided between the clamping block 3 and the adjusting rod 2 in this embodiment.
