Before insertion, the operating rod 507 is used to drive the second bevel gear 5063 to rotate, during the rotation process, the first bevel gear 5062 rotates, because the thread direction of the first guide rail 504 is opposite to the thread direction of the second guide rail 505, when the first bevel gear 5062 rotates to drive the sleeve 5061 to rotate, the first guide rail 504 and the second guide rail 505 can move relatively close to each other, at this time, the guide rod 5051 on the second guide rail 505 is inserted into the guide groove 5041, the second bevel gear 5063 continues to rotate, the spherical protrusion 5052 at the end of the guide rod 5051 is clamped in the arc-shaped groove 5042, and meanwhile, an operator feels the vibration of the spherical protrusion 5052 clamped in the arc-shaped groove 5042, and stops the rotation of the operating rod 507. The bayonet 501 can then be inserted into the bayonet hole. After the plugging is completed, the operating rod 507 is rotated in the direction, the first guide rail 504 and the second guide rail 505 are away from each other, the first limiting sliding block 502 and the second limiting sliding block 503 are driven to be away from each other, at this time, the spherical protrusion 5052 slides out from the arc-shaped groove 5042, and when the first limiting sliding block 502 and the second limiting sliding block 503 slide to a certain distance, the rotation is stopped. At this time, the first limiting sliding block 502 and the second limiting sliding block 503 can limit the plugging rod 501 from sliding out of the plugging hole, so that the safety in the transportation process is ensured.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
