[0022] The disassembly tool includes a supporting mechanism for supporting the lower working cylinder 2 and a disassembly mechanism for disassembling the compression valve 4 and the lower working cylinder 2 in cooperation with the supporting mechanism.

[0023] The support mechanism comprises a base 7 and two vertically and oppositely arranged positioning pins 6 on the base 7, a plurality of through holes 3 are uniformly arranged on the side wall of the lower working cylinder 2 in a circle, the lower working cylinder is hung to the positioning pins 6 through the through holes 3, and the positioning pins 6 extend into the inner cavity of the lower working cylinder 2, and the outer diameter of the positioning pins 6 is matched with the through holes 3 on the lower working cylinder 2.

[0024] At least one of the positioning pins 6 is slidably connected with the base 7 through a sliding mechanism, one of the positioning pins can be fixedly connected with the base 7, and the other positioning pin can be slidably connected with the base 7, or both of the positioning pins can be slidably connected with the base 7, the spacing between the two positioning pins 6 can be adjusted according to the positions of the through holes on different working cylinders, various models of working cylinders can be adapted, the application range is wide, and the cost is reduced, when the spacing between the two positioning pins 6 is adjusted, long handle screws can be screwed in the fixing holes on the positioning table to achieve quick installation and locking.

[0025] Specifically, a groove 9 is arranged on the base 7 in the transverse direction, the bottom of the positioning pin 6 is nested in the groove 9, the bottom of the slidably arranged positioning pin is further connected with a positioning table 10, at least one of the positioning pins 6 is slidably arranged in the groove with the corresponding positioning table 10, the positioning table 10 is provided with a fixing hole 11 for fixing a screw, and the positioning pin 6 and the positioning table 10 are made of 40Gr material and have good rigidity to avoid breakage during screwing.
