Referring to fig. 1-8, there are at least two support members slidably fitted to the carrier assembly 3, based on which the length of the telescopic members is adjusted by arranging the telescopic members corresponding to the two support members in forward or reverse rotation of the two support members relative to the carrier assembly 3;

the length of the telescopic rod piece is adjusted, and the aim is to form a mechanism for supporting, so that when the plate-shaped structural piece is placed in the barrel body 1, a base point capable of exerting force is provided, the plate-shaped structural piece is prevented from falling into the barrel body 1, the friction force is small due to the fact that the wires are in contact with each other, and the friction force is further reduced by the aid of the acid washing solution, so that the plate-shaped structural piece slides into the barrel body.

In addition, because the two support pieces are arranged in a sliding way compared with the bearing assembly 3, the supporting assembly 2 not only can change according to the specification of the plate-shaped structural member, but also can adjust the supporting point positions in the feeding direction, and the application range is wider.

In particular implementation, the carrier assembly 3 comprises a bubble base 31 and a base 32, the base 32 is connected with the bubble base 31, a gap for rotation of the support is provided between the base 32 and the bubble base 31, the support comprises a guide 22 and an air tube 21 rotatably mounted at the guide 22, one end of the guide 22 extends into the gap of the base 32 and the bubble base 31, the guide 22 can rotate relative to the base 32 and the bubble base 31 in the circumferential direction, the telescopic rod comprises a plug rod 23 rotatably connected with the adjacent air tube 21 and a sleeve 24, the plug rod 23 is inserted into the sleeve 24 and slidably adapted to the sleeve 24 to change the combined length when the guide 22 rotates relatively.

As shown in fig. 1, 2, 3 and 6, the two guiding elements 22 are placed in the interlayer between the bearing components 3, so that the two guiding elements 22 can be driven by the stress of the telescopic rod to the bearing components 3 to perform circumferential rotation, wherein the circumferential rotation has a certain characteristic:

(1) in the relative approaching movement of the two guides 22, the combined length of the telescopic rod between the two guides 22 is lowered, on the basis of which the telescopic rod divides the space above the carrier assembly 3 into a large and small semicircle.

(2) The combined length of the telescopic rod is greatest when the two guides 22 are at the furthest relative distance in the relative movement, on the basis of which the telescopic rod divides the space above the carrier assembly 3 into two semicircles of equal area.

Based on (1) and (2), by varying the relative distance of the two guides 22, the bracing point for bracing the plate-like structure can be adapted.

In particular, the guide 22 comprises a receiving box 224 slidably fitted to the inner wall of the tub 1 and a contact box 221 interposed between the base 32 and the bubble base 31, the contact box 221 being connected to the receiving box 224, for mounting a bubbling net 225 for generating bubbles at an end of the contact box 221 near the base 32, a docking tube 222 being mounted at an end of the receiving box 224 facing the air tube 21, the docking tube 222 being connected to the air tube 21;
