[0011] Preferably, the multiple groups of buffer rods are all arranged in an arc shape.

[0012] Preferably, the bottom ends of the multiple connecting tubes are connected to the adsorption tubes, and a pump body is provided on the base, and the pump body is connected to the bottom ends of the adsorption tubes.

[0013] Preferably, the multiple rotating plates have the same specifications and form an arc-shaped whole.

[0014] Preferably, the adsorption head is positioned at the middle portion of the inner rod and never exceeds the upper end of the inner rod.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:
