A plurality of locking holes 112 are arranged on the outer circle of the support device body 110, if necessary, the support device body 110 can be connected and pressed with the workbench through a connecting piece.

[0031] The support device body 110 is provided with an air channel 113 in the vertical direction (the vertical direction is horizontal with the axis), the air channel 113 is through with the air nozzle hole 111;And the air channel 113 is through on the side of the central axis, and is closer to the air nozzle hole 111 to avoid air source waste;The upper surface and the bottom surface of the support device body 110 are symmetrically provided with adsorption surfaces 114 based on the position of the air nozzle hole 111, both surfaces are provided with the same adsorption surface 114, either surface can be used (the other surface is connected with the table surface through the connecting screw rod 150) or both surfaces are used (the other surface is connected with the table surface through the adsorption mode), and the adsorption surface 114 does not need to be distinguished in use, so that the use mode is more free, and the use limitation is less.

[0032] Specifically, the adsorption surface 114 includes a first annular groove 1141, a second annular groove 1142, a third annular groove 1143 and a threaded hole 1144 arranged from outside to inside in sequence, and a plurality of annular grooves are combined to form a stable support surface, avoiding deformation of the thin-walled part during adsorption.

[0033] Wherein, see Fig. 3 , the shadow part is the adsorption surface A. The first annular groove 1141 is a closed annular groove, and an O-shaped sealing ring 140 is assembled in the first annular groove 1141, which ensures effective adsorption of the device. The inner groove wall of the second annular groove 1142 is provided with a first notch 1145 penetrating the second annular groove 1142 and the third annular groove 1143, the bottom of the first notch 1145 is an air passage 113, when the adsorption surface 114 is not used, a plug 130 is clamped in the first notch 1145 to avoid waste of air source; the inner groove wall of the third annular groove 1143 is provided with a second notch 1146 penetrating the threaded hole 1144 and the third annular groove 1143, the first notch 1145 and the second notch 1146 are arc notches, which facilitate the clamping of the plug 130 in the form of a bolt, and the position of the first notch 1145 and the position of the second notch 1146 are oppositely arranged, thereby designing a stable air flow passage to further improve the adsorption effect.
