When the locking cover 300 is in the locking position, the button 800 corresponds to the sleeve 400, and at this time, the button 800 is pressed downward, so that the button 800 drives the upper ratchet 500 to drive the lower ratchet 600 to move downward and compress the elastic element 700, when the upper end of the lower ratchet 631 moves downward to the bottom end C of the guide rib, the button 800 is released, the lower ratchet 600 and the upper ratchet 500 move upward under the restoring force of the elastic element 700, the lower ratchet 631 passes over the upper ratchet 510 and slides and rotates along the bottom surface of the guide rib, so that the guide rib 440 is clamped in the lower ratchet 631, as shown in fig. 9, the self-locking assembly is in the low position self-locking, and in the process, the lower ratchet 600 extends downward to press the upper coupler 240 downward, so that the upper coupler 240 and the lower coupler 110 are coupled and kept energized. When the key 800 is pressed downwards again, the key 800 drives the upper ratchet 500 to drive the lower ratchet 600 to move downwards and compress the elastic element 700, when the upper end of the lower ratchet 631 moves downwards to the bottommost end C of the guide rib, the key 800 is loosened, the lower ratchet 600 and the upper ratchet 500 move upwards under the restoring force of the elastic element 700, the lower ratchet 631 crosses the upper ratchet 510 and slides and rotates along the bottom surface of the guide rib, so that the guide rib 440 is clamped in the lower chute 640, the self-locking assembly is in high self-locking at the moment, the lower ratchet 600 retracts upwards and loses pressing force on the upper coupler 240 in the process, the upper coupler 240 resets under the restoring force of the spring and is disconnected from the lower coupler 110, at the moment, a user can rotate the locking cover 300 to the unlocking position to open the cover, and the key 800 and the sleeve 400 are arranged in a staggered.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
