The invention provides a manual unlocking device which comprises a gear and a spindle. A center sliding block is arranged in a center hole of the spindle. The spindle is provided with at least one sliding groove through which the center hole and the outside of the spindle are communicated in the radial direction. A sliding key is arranged in the sliding groove correspondingly. When the gear and the spindle are in the locked state, the sliding key is located in a sliding key slot, and the gear is circumferentially limited relative to the spindle. When the gear and the spindle are in the unlocked state, the center sliding block, a push rod and the sliding key are in axial linkage until the sliding key is disengaged from the sliding key slot in the gear, the circumferential limitation of the gear relative to the spindle is released. The manual unlocking device can be widely applied to occasions where the driving mode is changed to the follow-up mode and high reliability is required. The manual unlocking device is simple in structure, easy to operate and low in weight, can improve the system reliability remarkably, and can also realize reverse operation for mechanism locking. The reverse operation provides an effective solution for various occasions needing manual unlocking.
