Detailed Description

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

By figure 1 to 4, axial sleeve 1 around including, both sides are coaxial respectively around in the sleeve 1 are equipped with baffle 2, the coaxial first connecting pipe 3 that is equipped with in 2 front ends of baffle of front side, the coaxial second connecting pipe 4 that is equipped with in rear end of the baffle 2 of rear side, the internal diameter of first connecting pipe 3 is greater than the internal diameter of second connecting pipe 4, axial push-and-pull rod 5 about sliding connection respectively has in both sides around sleeve 1, the inner of every push-and-pull rod 5 all runs through sleeve 1 and is equipped with

arc cardboard

6, 6 relative openings of arc cardboard are relative and lie in its baffle 2 outsides that correspond the side about per two, the arc cardboard 6 dismantlement connection that per two openings are relative.

For better use effect, the outer edge surface of each push-pull rod 5 is sleeved with a tension spring 7 positioned between the arc-shaped clamping plate 6 and the sleeve 1.

In order to prevent the arc-shaped clamping plates 6 from damaging the pipeline, the inner surface of each arc-shaped clamping plate 6 is provided with a silica gel sheet 8.

In order to enable every two arc-shaped clamping plates 6 with opposite openings to be detachably connected, the upper ends and the lower ends of the two left arc-shaped clamping plates 6 are respectively provided with a limiting hook 9 in the left-right direction, the upper ends and the lower ends of the two right arc-shaped clamping plates 6 are respectively provided with a rectangular groove 10 in the left-right direction, and a limiting block 11 capable of being clamped in the limiting hook 9 is arranged in each rectangular groove 10.

In order to facilitate the medical staff to pull the push-pull rods 5, the free ends of the push-pull rods 5 are respectively provided with a pull ring 12.

In order to prevent dust from entering the device, the first connecting pipe 3 and the second connecting pipe 4 are respectively detachably connected with a dustproof plug 13.
