The utility model can efficiently assemble the protective shell without the aid of tools, and is easy to use.

[0004] However, the above method still has the following defects: while rotating the handle, the staff also needs to stretch the horizontal plate installed in the handle area. This additional step undoubtedly significantly increases the complexity of the operation, seriously hinders the smooth rotation adjustment of the handle, and thus slows down the overall progress of the protective shell disassembly and assembly work to a certain extent, affecting the work efficiency. Utility Model Content

[0014] Compared with the related art, the hydraulic motor valve body with a protective housing provided by the present invention has the following beneficial effects:

[0015] 1. Through the set limit assembly, pulling the pull cap can drive the pull rod and the rack plate to move upward smoothly, thereby realizing the engagement and separation between the rack plate and the gear. This operation allows the user to directly operate the adjustment handle to drive the support rod and the worm to rotate synchronously. Due to the precise engagement of the worm and the worm wheel, the rotating rod and the card block on its surface also rotate synchronously, so that the card block can be easily inserted into or out of the slot, thereby greatly facilitating the rapid disassembly and assembly of the shell. At the same time, this design does not cause any obstruction to the smooth rotation of the adjustment handle while ensuring the disassembly and assembly efficiency, effectively improving the overall progress and work efficiency of the protective shell disassembly and assembly.

[0016] 2. Through the mutual cooperation between the worm and the worm wheel, the two have the function of self-locking, which can tightly limit the movement of the rotating rod and the block. At the same time, the limit assembly ensures the stable engagement between the rack plate and the gear, and further implements an effective limiting effect on the support rod and the worm. This design not only realizes the primary limiting of the rotating rod and the block, but also enhances the fastening effect between the shell and the base plate through the secondary limiting mechanism, ensuring the overall stability and reliability.
