The adsorption assembly 11 is provided with a first exhaust pipe 113 extending in the left-right direction. The piston member 12 is movably arranged in the first exhaust pipe 113. When the piston member 12 moves towards the exhaust groove 111, the air in the exhaust groove 111 can be compressed, so that the air is discharged from the exhaust groove 111 under pressure. More specifically, the piston member 12 is provided with a second exhaust pipe 121 extending in the left-right direction. The right side of the second exhaust pipe 121 is provided with an exhaust hole 1211. The piston member 12 and the first exhaust pipe 113 form a negative pressure space 100 communicating with the exhaust groove 111. The negative pressure space 100 is provided with a first spring 122. The first spring 122 can maintain the negative pressure state of the negative pressure space 100. The one-way valve 15 is at least partially arranged in the second exhaust pipe 121, which can limit the flow of air from the exhaust hole 1211 into the first exhaust pipe 113. The pressing member 13 is at least partially arranged on the right side of the piston member 12, and the pressing member 13 abuts against the piston member 12. When the pressing member 13 drives the piston member 12 to move to the right, the piston member 12 compresses the air in the negative pressure space 100, and the air pressure is greater than the resistance of the one-way valve 15, so that the air can be discharged from the negative pressure space 100 through the one-way valve 15. The housing 14 is at least partially arranged on the adsorption assembly 11 and the pressing member 13, and the outer peripheral wall is provided with an anti-dropping member 141 for limiting the separation of the to-be-hung member.

[0025] The adsorption device realizes rapid adsorption and stable fixation of the hanging member by arranging the exhaust groove 111 and the suction cup adsorption part 112 in the adsorption assembly, and driving the piston member 12 to discharge air to form the negative pressure space 100 by the pressing member 13. The device does not need complex rotation or locking operation, and only needs simple pressing to complete adsorption, which greatly reduces the use difficulty and improves the use efficiency. At the same time, the device avoids air backflow to the negative pressure space 100 by arranging the one-way valve 15 and the spring structure, which further improves the air tightness and adsorption stability of the device.

[0026] As shown in Figure 2 The piston member 12 includes a piston ring 123 and a connecting ring 124.

The second spring 154 is at least partially sleeved on the supporting piece 152, one end of the second spring 154 abuts against the bracket 151, and the other end abuts against the plug 153, and is used for maintaining the plug 153 to close the exhaust hole 1211. Through the above arrangement, the one-way valve 15 has compact structure and reliable performance, and can effectively control the one-way flow of air. The second spring 154 provides stable return force, so as to ensure that the exhaust hole 1211 is quickly closed after the exhaust is completed, and avoid the problem of pressure relief of the negative pressure space 100.
