The boss 2411 can be located on the central axis of the spring, that is, the part of the spring is arranged around the boss 2411. Preferably, the diameter of the boss 2411 is equal to or slightly smaller than the inner diameter of the spring. At this time, an elastic end of the spring can be clamped and fixed with the boss 2411 .

The boss 2411 is provided with a through hole coaxially corresponding to the first through hole 2211 , and the boss 2411 here may be, but not limited to, a circular boss. The limiting plate 2441 may include a short plate 2443 and a long plate 2444 respectively located on both sides of the pin shaft 245 to form a lever structure to save labor.

When the suction member 23 needs to be separated from the bearing surface, the worker can step on the footrest 2445, so that the high point of the pressing protrusion 2442 on the limiting plate 2441 presses the force-bearing high point part 211, so that the shaft 212 of the rod 21 is pressed until part of it penetrates out of the suction member 23, and a gap is formed between the suction member 23 and the bearing surface when the suction member 23 is transferred. The stable separation operation between the adsorption member 23 and the bearing surface can be achieved by the force. During the whole separation operation, the staff only needs to exert the pressing force on the rod 21, which saves more effort, does not cause damage to the adsorption member 21 during the separation operation, and also avoids the separation of the traditional adsorption base. In the operation process, there are situations such as re-adsorption on the bearing surface, resulting in invalid action, damage to the adsorption parts, and even safety hazards.

Combining the first and second embodiments, the adsorption base provided by the present invention includes a rod, an assembly part and an adsorption part, and the force-receiving part of the rod is used to receive external torsion force (rotation force) or pressing force, so that the rod's The rod body can be switched between passing through the adsorption piece and not passing through the adsorption piece: when the force-receiving part is in the first force-bearing state, a part of the rod body passes out of the adsorption piece; so When the force-receiving part is in the second force-receiving state, the shaft does not penetrate out of the adsorption member. It is worth noting that, in one embodiment, the rod is threaded through the assembly part and the suction part in sequence; in another embodiment, the rod is passed through the suction part, the assembly part is provided on the suction part, and the rod does not need to be The fittings can be installed freely on the suction parts. During the entire separation operation of the adsorption base and the bearing surface, the staff only needs to apply a small force, and the adsorption parts will not be damaged during the separation operation, and at the same time, the traditional adsorption base can be avoided in the separation operation process. In some cases, there are situations such as re-adsorption on the bearing surface, resulting in invalid action, damage to the adsorption parts, and even safety hazards.

Each component in the present invention can be customized and produced separately, and can be assembled flexibly, and the structure is relatively simple and stable.

The above-mentioned serial numbers of the embodiments of the present invention are only for description, and do not represent a comparison of the advantages and disadvantages of the embodiments.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection of the present invention. within the range.
