[0036] As can be seen, the two second cylinders 210 symmetrically drive the mounting plate 22, and with the help of four guide telescopic rods 211 for limiting, the stability of the mounting plate 22 in raising and lowering is ensured.

[0042] In one embodiment, the second adsorption member includes a second mounting rod 263 and a plurality of second suction cups 264. A mounting groove 265 is provided in the middle of the second mounting rod 263. The mounting groove 265 is configured to mount the first mounting rod 260.
