Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, connecting rod 1 including the left and right directions, the flowing liquid hole 2 that link up about seting up on connecting rod 1, both ends are equipped with the joint pipe 3 with flowing liquid hole 2 intercommunication respectively about connecting rod 1, axial annular knurl dish 4 about threaded connection has on connecting rod 1, it has the bull stick 5 that runs through its left end to rotate to be connected with on the annular knurl dish 4, bull stick 5 left end articulates through the connecting rod 6 that the low right side is high in a left side has the dead lever 7 that can reciprocate, dead lever 7 lower extreme is equipped with can with left joint pipe 3 contact and arc 8 that the arc is down, connecting rod 1 right side sliding connection has about the direction and the gag lever post 9 that can reciprocate, set up the spacing groove 10 that the opening link up down and around and on the gag lever post 9, the bulge loop on the medical tee bend interface can block into in the spacing groove 10.

In order to enable the fixing rod 7 to move up and down, an L-shaped groove 11 with an opening facing to the right and an upper side communicated with the outside is formed in the fixing rod 7, an L-shaped sliding rod 12 is arranged at the left end of the connecting rod 1, and the upper side of the sliding rod 12 is in sliding connection with the L-shaped groove 11.

In order to increase the friction force between the arc-shaped plate 8 and the drainage tube, a silica gel pad 13 is arranged on the lower side of the arc-shaped plate 8.

In order to facilitate the up-and-down movement of the limiting rod 9, the upper end of the limiting rod 9 is fixedly connected with the connecting rod 1 through a spring 14, and the right end face of the limiting rod 9 is an inclined plane which is low at the left and high at the right.

In order to achieve a better fixing effect, the lower side surface of the limiting rod 9 is an arc-shaped surface with a downward arc opening.

In order to increase the air tightness of the device, the right joint pipe 3 is provided with a sealing gasket 15.

When the utility model is used, the silica gel pad 13 is arranged to be separated from the joint pipe 3 in the initial state, the left joint pipe 3 is inserted into the drainage pipe, the knurling disc 4 is rotated clockwise, the knurling disc 4 rotates and simultaneously drives the rotating rod 5 to move leftwards, the rotating rod 5 drives the fixed rod 7 to move downwards through the connecting rod 6, the fixed rod 7 drives the silica gel pad 13 to move downwards through the arc-shaped plate 8, and the sliding rod 12 moves upwards relative to the fixed rod 7;

when the silica gel pad 13 is contacted with the drainage tube, the drainage tube is fixed on the left connector tube 3 by the silica gel pad 13, and the connection between the drainage tube and the connecting rod 1 is completed;

after the drainage tube is connected with the connecting rod 1, the connecting rod 1 is moved rightwards, the connector tube 3 on the right side is inserted into the medical tee joint, when the inclined surface of the limiting rod 9 is contacted with the convex ring of the medical tee joint, the medical tee joint pushes the limiting rod 9 to move upwards along with the penetration of the connector tube 3 into the medical tee joint, and the spring 14 is compressed;
