[0029] In this embodiment, after adjusting the drive frame 42 by rotating the screw 43, the gear 48 can be driven to rotate by the rack 46 on the drive frame 42, so that the transmission block 47 is driven by the gear 48 to slide out of the protective shell 2 and separate from the fixing ring 45, thereby facilitating the operator to disassemble the protective shell 2 and the hydraulic motor 3 together, thereby improving the convenience of overall disassembly and assembly.

[0030] The inner wall of the protective shell 2 and the interior of the support plate 41 are both provided with through holes located outside the transmission block 47 , so that the sliding transmission block 47 can extend into the protective shell 2 through the through holes, and the support plate 41 is arc-shaped.
