Detailed Description

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

By figure 1 to 6, axial circular plate 1 about including, set up a plurality of round holes 2 that link up from top to bottom along its circumferencial direction equipartition and on the

circular plate

1, 2 upper ends of every round hole are all coaxial to be equipped with first arc 3, U-shaped groove 4 has all been seted up to 3 outer ends of every first arc, 3 inner hinges of every first arc have second arc 5, every second arc 5 all is relative rather than 3 openings of articulated first arc, the free end of every second arc 5 all is rather than the U-shaped groove 4 dismantlement connection of corresponding side, the coaxial drum 6 that is equipped with of circular plate 1 lower extreme, be equipped with a plurality of spiral plates 7 with round hole 2 one-to-one in the drum 6.

In order to make every second arc 5 all with rather than 3 dismantles connections of articulated first arc, 5 outer ends of every second arc all set up the spacing hole 8 that link up from top to bottom, the through-hole 9 that link up from top to bottom is all seted up to 4 upsides of every U-shaped groove, all be equipped with gliding gag lever post 10 from top to bottom in every through-hole 9, every gag lever post 10 all can insert rather than the spacing downthehole 8 that corresponds, through-hole 9 and coaxial bumping post 11 that is equipped with are all stretched out to every gag lever post 10 upper end.

In order to enable the limiting rod 10 to reset automatically, the upper end of each blocking column 11 is coaxially provided with a cylindrical block 12, the diameter of each cylindrical block 12 is larger than that of each blocking column 11, and the outer edge surface of each blocking column 11 is sleeved with a tension spring 13 between each cylindrical block 12 and the first arc-shaped plate 3.

In order to block up the round holes 2 which are not used, the upper end of the round plate 1 is hinged with a plurality of round cover plates 14 which are in one-to-one correspondence with the round holes 2 through a pin shaft, and each round cover plate 14 can block the round hole 2 on the corresponding side.

In order to facilitate the opening of the circular cover plates 14, each circular cover plate 14 is provided with a pull ring 15.

For better fixing effect, the upper and lower sides of the outer edge surface of the cylinder 6 are respectively provided with an annular trapezoid block 16.

When the utility model is used, firstly, the cylinder 6 in the device is inserted into the sewer pipeline of the dental chair, so that the lower end face of the circular plate 1 is contacted with the upper end face of the sewer pipeline of the dental chair, the two trapezoidal blocks 16 clamp the cylinder 6 in the sewer pipeline of the dental chair, then the cylinder block 12 is pulled upwards, the cylinder block 12 drives the limiting rod 10 to slide upwards in the limiting hole 8 through the stop post 11, meanwhile, the tension spring 13 is pulled upwards by the cylinder block 12, after the limiting rod 10 is completely separated from the limiting hole 8, the second arc-shaped plate 5 is opened and the cylinder block 12 is loosened, the cylinder block 12 moves downwards under the pulling of the tension spring 13 until the lower end face of the stop post 11 is contacted with the upper end face of the first arc-shaped plate 3;

the pull ring 15 is pulled outwards, the pull ring 15 drives the circular cover plate 14 to swing outwards around the axis of the pin shaft, when the circular cover plate 14 is completely opened, the pull ring 15 is stopped to be pulled, the saliva suction pipe sewer pipeline is inserted into the opened circular hole 2, then the cylindrical block 12 is pulled upwards, the cylindrical block 12 drives the limiting rod 10 to slide upwards through the stop post 11, the lower end face of the limiting rod 10 is aligned with the upper end face of the U-shaped groove 4, at the moment, the second arc-shaped plate is closed, the limiting hole 8 is aligned with the limiting rod 10, the cylindrical block 12 is loosened, the limiting post slides into the limiting hole 8 under the action of the tension spring 13, the second arc-shaped plate 5 is fixed at the current position, and the saliva suction pipe sewer pipeline is fixed at the current position through the second arc-shaped plate 5 and;
