The sliding ring 417 is convenient for rotating and opening and is sleeved on the output end of the torque motor body 2. The rotating block 416 drives the sliding ring 417 to slide on the output end of the torque motor body 2 under the attraction of the electromagnet 415, and at the same time, the sliding ring 417 drives the first elastic plate 47 to slide on the first steering block 48 and the second steering block 49, and at the same time, the first elastic plate 47 slides on the sliding roller 411. An electromagnet 415 is fixedly installed on the inner wall of the rectangular through hole 414 near the base 1. When the torque motor body 2 is powered off, the electromagnet 415 adsorbs the rotating block 416 when it is powered on, so that the rotating block 4 16 slides in the rectangular through hole 414, and the first elastic plate 47 is rotatably installed on the side of the sliding ring 417 away from the rectangular through hole 414. The first elastic plate 47 drives the slide rod 45 to slide in the groove 44 under the steering of the second steering block 49, so that the slide rod 45 drives the second gear chain plate 43 to move toward the first gear chain plate 42, so that the second gear chain plate 43 and the first gear chain plate 42 are staggered and meshed with each other, which is convenient for limiting the first gear chain plate 42. Two support blocks 410 are fixedly installed on the side of the torque motor body 2 close to the second gear chain plate 43, and a sliding roller 411 is fixedly installed between the two support blocks 410.

The triangular plates on the first and second toothed discs 42, 43 are tilted at an angle. The rotating block 416 is installed above the sliding ring 417. The side of the first elastic plate 47 slides in contact with the inclined surfaces of the first and second steering blocks 48, 49, facilitating locking of the connector after the torque motor body 2 is powered off. During plug-in locking, the inertia of the connector can easily damage not only the connector but also the output end of the torque motor body 2. Since the electromagnet 415 attracts the rotating block 416, after the rotating block 416 is separated from the connector, the first and second toothed discs 42, 43 are used to cooperate and limit the self-locking, thus minimizing the need to manually pull the connector apart. This is beneficial to improving the elastic self-locking ability of the device, the service life of the self-locking parts, the automaticity of the self-locking device, and the user experience of the device.
