Specific embodiment one:

[0030] like Figure 1-3 As shown, a torque-limited hydraulic coupler disassembly and removal device comprises a top shaft rod 1, the top shaft rod 1 is detachably connected to a coupler connector 2, one end of the top shaft rod 1 is provided with a mating end head mating with a motor shaft, the mating end head is an arc-shaped head structure, and a movable end 3 is fixedly provided on the top shaft rod 1 away from the mating end head;

[0031] The coupler connector 2 is detachably connected to the torque-limiting hydraulic coupler;

[0032] The coupler connector 2 is a sleeve structure, an internal and external thread structure is arranged on the coupler connector 2, and the coupler connector 2 is connected to the drawing coupler thread section 4.

[0033] The coupler connector 2 is in contact with the corresponding end surface of the movable end 3 .
