The manual unlocking device comprises a lock body arranged on a panel of the sliding door, and a handle installed on the lock body. The manual unlocking device is characterized in that the middle of the handle is provided with an installation hole allowing the lock body to penetrate through; the head of the handle is hinged to the panel of the sliding door through a pin shaft; a lock rod capable of moving reciprocally relative to a lock cylinder of a door frame is further hinged to the head of the handle through the pin shaft; besides, the free end of the lock rod is provided with an elastic member capable of keeping the free end of the lock rod always in a trend to be disengaged from the lock cylinder of the door frame when the sliding door is in a locked state. Compared with the prior art, the manual unlocking device for the sliding door has the advantages that the handle in linkage with the lock body drives the lock rod to act, and the free end of the lock rod is made to move upwards along with the rotation of the lock body and abut against the lock cylinder of the door frame, so that the unlocking of the sliding door is achieved. An unlocking body is arranged on the side of a platform of the sliding door and the sliding door can be opened through a key, and thus workers can take part in rescue conveniently and the mistaken opening by other people can be prevented. The manual unlocking device has the characteristics of being high in practicability and convenient to operate.
