[0011] As a preferred solution of the present invention, the motor cover is mounted on the outer wall of the housing by bolts, and the button switch, the motor, and the first circuit board and the second circuit board are all connected electrically.

[0012] As a preferred solution of the present invention, the manual lever is designed as an L-shaped structure, and the button switch and the manual lever penetrate and extend outside the housing.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a self-priming and tightening lock is designed, and the locking mechanism in the device is used to lock the lock catch. The box door or cabinet door is gently pushed to insert the lock catch into the shell. The lock catch entering the shell will push the lock hook to rotate downward, and the lock hook is inserted into the lock catch. The lock hook is engaged with the lock rod in the first gear. The second circuit board receives the first gear position signal of the lock hook, and the second circuit board controls the motor. The motor drives the worm wheel to rotate through the worm, and the rotating worm wheel drives the transmission gear to rotate through the left gear. The transmission gear drives the double gear to rotate through the middle gear. The rotating double gear drives the tooth plate to rotate upward, and the tooth plate rotating upward drives the lock hook to continue to rotate downward through the sliding pin. The lock hook rotating downward will be completely inserted into the lock catch. At this time, the lock hook is stuck by the lock rod. After the second circuit board receives the signal, the second circuit board starts the motor to start reversing. The motor drives the worm wheel to rotate in the opposite direction through the worm, and the reversely rotating worm wheel drives the gear to rotate in the opposite direction through the left gear. The transmission gear rotates in the opposite direction, and the transmission gear drives the double gear to rotate in the opposite direction through the middle gear. The reversely rotating double gear drives the tooth plate to rotate downward, and the downward rotating tooth plate drives the sliding pin back to its original position, and the second circuit board stops the motor operation. When closing the box door or cabinet door, there is no need to push the box door or cabinet door hard to close it. You only need to push the lock into the shell to lock it. The structural design is simple, and the motor is controlled to rotate forward and reverse to achieve locking and unlocking. The product runs more stably, which solves the problem that the existing locks require the staff to push the box door or cabinet door hard to lock it. When the force to push the box door or cabinet door is small, the large box door mechanical tightening lock with a sealing strip is difficult to compact and have a good sealing effect. The box door or cabinet door cannot be locked and the safety is poor. At the same time, the self-priming lock is always consistent after the tightening force and position are installed and debugged, which solves the problem that the mechanical lock is not operated consistently each time and is not sealed and breathable after locking.
