The scheme is preferably as follows: the diameter of the upper disc is the same as that of the lower disc.
The scheme is preferably as follows: the upper disc and the lower disc can be fixedly connected through a stud, and the sealing mode is compression sealing or coating sealing.
The scheme is preferably as follows: the axis of the through hole is positioned at the central position of the concentric annular groove.
The scheme is preferably as follows: the valve control mechanism comprises a plug and a push rod; the plug is fixedly connected with the push rod; the plug can seal the exhaust pipe; the push rod can drive the plug to move in the branch exhaust tube.
The beneficial effect of this scheme can learn according to the statement to above-mentioned scheme, because adopt the split type structure of upper and lower wall in this scheme, the hanging wall bottom surface sets up a plurality of concentric ring channels, corresponds in the groove and sets up the through-hole, sets up the exhaust duct in the lower wall, and the position that corresponds concentric ring channel on the pipeline sets up the gas pocket to set up the state that the state of bleeding of gas pocket can be controlled to valve control mechanism, thereby realize controlling the state of bleeding of through-hole in the hanging wall, realize the quick adjustment of the absorption diameter of suction tool.
Therefore, compared with the prior art, the invention has prominent substantive features and remarkable progress, and the beneficial effects of the implementation are also obvious.

Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
Example (b):
as shown in fig. 1-4, after the upper disc and the lower disc are relatively attached, the upper disc connecting hole corresponds to the lower disc connecting hole, the upper disc and the lower disc are locked by a stud to realize sealing, and the lower surface of the upper disc is provided with a plurality of concentric annular grooves with different radiuses; a plurality of through holes are formed in each concentric annular groove; an air exhaust pipeline is arranged inside the lower disc; a plurality of air holes are formed in the air exhaust pipeline and penetrate through the upper surface of the lower disc; at least one air hole is correspondingly arranged at the central position of each concentric annular groove; the air extraction pipeline comprises a main air extraction pipe and branch air extraction pipes; the branch exhaust pipes are arranged along the diameter direction of the lower disc and penetrate through the lower disc; the main exhaust pipe is vertical to the branch exhaust pipes and is communicated with the branch exhaust pipes at the center of the lower disc; the two ends of the branch exhaust pipe are correspondingly provided with valve control mechanisms; the valve control mechanism can seal the branch exhaust pipe and can move in the branch exhaust pipe; the diameters of the upper disc and the lower disc are the same; the axis of the through hole is positioned at the central position of the concentric annular groove; the valve control mechanism comprises a plug and a push rod; the plug is fixedly connected with the push rod; the plug can seal the exhaust pipe; the push rod can drive the plug to move in the branch exhaust tube.
