Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the drawings.

The utility model provides a by fig. 1 to 4, including interior sleeve pipe 1, interior sleeve pipe 1 front end coaxial dismantlement is connected with insert post 2, insert post 2 front end stretches out interior sleeve pipe 1 and coaxial be equipped with carousel 3, coaxial be equipped with swivel 4 on the carousel 3, swivel 4 and interior sleeve pipe 1 front end outer fringe face laminating, interior sleeve pipe 1 upper left and right sides sliding connection has guide post 5 respectively, open outwards's guide way has been seted up respectively to the left and right sides on insert post 2, the guide way comprises inverted L-shaped groove 6, chute 7, cross slot 8 intercommunication, inverted L-shaped groove 6 rear end and outside intercommunication, chute 7 is the shape of downside backward slope and its lower extreme and inverted L-shaped groove 6 intercommunication, chute 7 upper end and cross slot 8 intercommunication.

In order to plug the front end of the sleeve, the rear end of the turntable 3 is made of elastic materials.

In order to facilitate the movement of the guide post 5, rectangular grooves 9 are respectively formed in the left side and the right side of the front end of the inner sleeve 1, rectangular plates 10 positioned in the rectangular grooves 9 are arranged on the guide post 5, and two rectangular opposite ends are connected with the rectangular grooves 9 through pressure springs 11.

In order to facilitate the control of the movement of the guide posts 5, the opposite end surfaces of the two guide posts 5 are inclined planes with the front sides inclined towards the axis of the inner sleeve 1.

In order to facilitate the rotation of the swivel 4, a plurality of damping rods 12 are uniformly distributed along the circumferential direction of the swivel 4 on the outer edge surface of the swivel.

In order to facilitate the insertion of the guide post 5 into the guide groove, the length of the swivel 4 is greater than the length of the spigot 2.

When the utility model is used, the inserted post 2 is not inserted into the front end of the inner sleeve 1 in the initial state, at the moment, the guide post 5 is not inserted into the inner sleeve 1, the normal use of the inner sleeve 1 is not affected, when the inner sleeve 1 is required to be plugged, the turntable 3 is moved, so that the plug post 2 is inserted into the inner sleeve 1, and meanwhile, the inner sleeve 1 is inserted between the plug post 2 and the swivel 4;

the swivel 4 is in inclined surface contact with the guide posts 5 and pushes the two guide posts 5 to move relatively, the two guide posts 5 drive the rectangular plate 10 to move and squeeze the pressure spring 11, meanwhile, the guide posts 5 move to the rear of the inserting posts 2, the inserting posts 2 are in contact with the guide posts 5 along with the continuous backward movement of the rotating disc 3, at the moment, the rotating disc 3 rotates to enable the guide posts 5 to move to the inverted L-shaped grooves 6 relative to the inserting posts 2, then the rotating disc 3 is continuously moved backward, the rotating disc 3 is enabled to move from the inverted L-shaped grooves 6 to the chute 7, at the moment, the rotating disc 3 is rotated anticlockwise, and the guide posts 5 pass through the chute 7 and move into the transverse grooves 8;
