the bottom of the suction cup 20 is attached to the adsorption plane 90, the first peripheral sealing edge 207 is attached to the adsorption plane 90, and a gap of 0.5mm is left between the first air sealing ring 206 and the adsorption plane 90. When the movable handle assembly 30 is driven by external force to move upwards to drive the middle part of the sucker 20 to move upwards until the clamping tongue 311 is not clamped with the clamping plate 401, the size of the circular adsorption groove 204 is increased, air in the outer ring adsorption groove 205 flows into the circular adsorption groove 204 in a one-way mode through a gap between the first air sealing ring 206 and the adsorption plane 90, the outer ring adsorption groove 205 generates negative pressure, the arc surface 2062 of the first air sealing ring 206 is attached to the adsorption plane 90, the bottom of the first air sealing ring 206 is driven to bend towards the inside of the circular adsorption groove 204, and therefore the attachment of the first air sealing ring 206 and the adsorption plane 90 forms a check valve structure similar to a duckbill valve.

Then, the external force applied to the movable handle assembly 30 is released, and under the action of the restoring force of the pressing spring 12, the movable handle assembly 30 drives the middle portion of the suction cup 20 to move downward to press the circular suction groove 204, but due to the check valve structure between the first air sealing ring 206 and the suction plane 90, the air in the circular suction groove 204 cannot flow back to the outer ring suction groove 205, so that the outer ring suction groove 205 maintains the negative pressure, and the circular suction groove 204 is pressed, so that a part of redundant air is discharged from the one-way exhaust valve 60.

And the movable handle component 30 is driven by external force to move upwards again, and the middle part of the sucker 20 is driven to move upwards until the clamping tongue 311 is not clamped with the clamping plate 401, part of air left in the outer ring adsorption groove 205 continuously flows into the circular adsorption groove 204 through the space between the first air sealing ring 206 and the adsorption plane 90, the vacuum degree of the outer ring adsorption groove 205 is improved, and the negative pressure is increased. The external force applied to the movable handle assembly 30 is released again, and likewise, a part of the surplus air is discharged from the one-way exhaust valve 60 as the circular absorption groove 204 is pressed by the pressing spring 12.

Repeating the above operations, the negative pressure of the outer ring adsorption groove 205 is increased, the arc-shaped surface 2082 of the second air sealing ring 208 is attached to the adsorption plane 90, the groove surface 2050 is also attached to the adsorption plane 90, at this time, the outer ring adsorption groove 205 has less air and high vacuum, and when the movable handle assembly 30 is driven by external force to move up, the remaining air flows from the ring groove 2051 and the radial groove 2052 to the second air sealing ring 208, and flows into the circular adsorption groove 204 through between the arc-shaped surface 2082 of the second air sealing ring 208 and the adsorption plane 90, and between the arc-shaped surface 2062 of the first air sealing ring 206 and the adsorption plane 90. The radial wedge grooves 2053 serve to facilitate the flow of gas into the largest ring groove 2051. Then, the movable handle assembly 30 is driven to drive the middle portion of the suction cup 20 to move upward until the latch 311 and the clamping plate 401 form a clamping connection, so that the movable handle assembly 30 can be fixed, that is, the generated adsorption force is maintained.

The carrier eliminates the vacuum degree and releases the adsorption process: as shown in fig. 5, the shift lever 50 is shifted to rotate the shift lever 50 toward the movable transverse plate 40 until the latch 311 and the latch plate 401 are separated from the latching constraint, and the control rod 55 is pulled up to separate the rubber plug 53 and the air inlet 203, the outer ring adsorption groove 205 is communicated with the outside atmosphere through the air inlet 203, and the push-down spring 12 pushes down the movable handle assembly 30 and drives the inner circle 201 of the suction cup 20 to move down to the initial position, so that the negative pressures of the circular adsorption groove 204 and the outer ring adsorption groove 205 are both eliminated, and the adsorption is released.
