As shown in Figure 13, when the solenoid is in a power-off state, the mandrel 11 moves away from the solenoid under the action of the magnetic field, thereby pushing the connecting rod 3 to move away from the mandrel 11, and the connecting rod 3 It is fixedly connected with the adjusting rod 7, and the connecting rod 3 drives the rack 71 provided on the adjusting rod 7 to move away from the solenoid. Since the rack 71 is meshed with the brake block 4, the rack 71 drives the brake block 4 along the Turn clockwise to make the lock unlocked. At this time, after the power is cut off, the magnetic field generated by the solenoid disappears, and the action of the return spring 9 makes the connecting rod 3 and the adjusting rod 7 move toward the direction of the solenoid under the action of the return spring 9, so that the adjustment rod 7 moves to the direction of the solenoid. The set rack 71 drives the brake block 4 to rotate counterclockwise, so that the brake groove 42 returns to the position shown in the figure, so that the lock catch 5 and the brake block 4 abut, and the lock catch device returns to the power-off and locked state.
