In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: the utility model provides a manual hydraulic special pulp locking device, which aims to simplify the manual locking step of a servomotor.

1. When the servomotor is required to be locked, the locking rod is inserted into the outer wall of the servomotor, at the moment, the locking protruding block enters the annular groove formed in the outer wall of the servomotor, and the bolt penetrates through the bolt hole and is screwed, so that the locker is fixedly mounted on the outer wall of the servomotor, the manual locking step is finished, the screw rod is not required to be rotated, the manual locking step is simplified, and the locking efficiency is greatly improved.

2. When the locking device is installed, a gap exists between the locking device cap and the outer wall of the connector, and when the locking device needs to be removed, the locking device cap can be quickly lifted through the gap, so that quick disassembly is facilitated.
