Since grooves 8 are provided on both sides of the thicker end of the mounting tube 5 and springs 9 are fixed in the grooves 8, when the two limit blocks 11 are opened and leveled, they can be abutted against the through hole 2 of the disk body 1 and pushed into the groove 8 accordingly, and the mounting tube 5 continues to penetrate the through hole 2 of the disk body 1 until the groove 8 passes through the through hole 2 and the limit block 11 is not abutted. The spring 9 restores the limit block 11 to push the limit block 11 out of the groove 8 and keep the limit block 11 level, and the mounting tube 5 is lifted toward the outside of the disk body 1 until the limit block 11 abuts against the inner surface of the disk body 1, and the installation of the mounting tube 5 is completed, so that the mounting tube 5 cannot be pulled out of the disk body 1. At this time, the threaded connecting tube 12 is connected, and the air nozzle 13 of the connecting tube 12 is connected to the pneumatic component for extracting vacuum; in summary, the entire installation process only requires the end of the mounting tube 5 with the limit block 11 to pass through the through hole 2 of the disk body 1 and then lift it up.

[0020] In this embodiment, specifically, a section with a larger diameter of the mounting tube 5 matches the size of the through hole 2 of the disc body 1, and grooves 8 are provided at the bottom of both sides of the section with a larger diameter of the mounting tube 5, and the limit blocks 11 are hinged in the grooves 8, and springs 9 are vertically fixed to the inner sides of the two grooves 8. When the limit blocks 11 are turned toward the grooves 8, the springs 9 can be compressed and completely placed in the grooves 8, and when the springs 9 are restored, the limit blocks 11 can be completely pushed out of the grooves 8;

[0021] The disc body 1 is a common existing suction cup, with a concave inner surface and a convex outer surface.

[0022] In this embodiment, specifically, a mirror-image abutment block 10 is fixed to one end of the mounting tube 5 close to the groove 8. When the limit block 11 flips out of the groove 8, the inner surface can be flush with the bottom end surface of the mounting tube 5, and one side abuts against the abutment block 10.
