[0027] A limit assembly, which is arranged inside the connecting assembly;

[0028] The sliding component is arranged on the inner side of the limiting component.

[0029] In this embodiment, preferably, the pulling assembly includes a handle 100 fixed on the surface of the placement plate 2, which can pull the placement plate 2 to move.

[0030] In this embodiment, preferably, the connecting component includes connecting grooves 200 symmetrically opened on both sides of the inner wall of the drying rack 1 at equal distances and connecting blocks 201 symmetrically fixed on both sides of the placement plate 2. The connecting blocks 201 are snap-connected with the connecting grooves 200 to facilitate the connection between the placement plate 2 and the drying rack 1.

[0031] In this embodiment, preferably, the guide assembly includes guide grooves 300 symmetrically opened on both sides of the connecting block 201 and guide blocks 301 symmetrically fixed on both sides of the inner wall of the connecting groove 200. The guide blocks 301 are slidably connected to the guide grooves 300, so that the connecting block 201 can play a docking guide role.

[0032] In this embodiment, preferably, the limiting assembly includes a limiting groove 400 opened at the end of the connecting block 201 and a built-in groove 401 opened inside the connecting groove 200, and a limiting buckle 402 is arranged inside the built-in groove 401. The limiting buckle 402 is engaged with the limiting groove 400 to position the connecting block 201, and a telescopic spring 403 is connected between the limiting buckle 402 and the built-in groove 401 to drive the limiting buckle 402 to reset and move.

[0035] The working principle and use process of the utility model are as follows: when the height of the placement plate 2 needs to be adjusted, the handle 100 is first pulled to drive the placement plate 2 to move out from the inner side of the drying rack 1, and drive the connecting block 201 to slide inside the connecting groove 200 to squeeze the limiting buckle 402. The limiting buckle 402 is squeezed by an external force to cause the telescopic spring 403 to withdraw from the inside of the limiting groove 400 and retract into the inside of the built-in groove 401, and at the same time drive the sliding block 501 to slide in the sliding groove 500 to play a moving guiding role, so that the connection block 201 can be driven to slide inside the connecting groove 200, and the guide groove 300 can be driven to slide on the surface of the guide block 301 to play a moving guiding role, so that the placement plate 2 and The drying rack 1 is disassembled and then rotated to a suitable height to embed the placement plate 2 into the interior of the drying rack 1, so that the connecting block 201 is docked with the connecting groove 200 of the corresponding height, and the guide groove 300 is driven to slide and connect with the guide block 301 to play a guiding role, so that the connecting block 201 can be completely inserted into the interior of the connecting groove 200. At this time, the limit buckle 402 is reset from the interior of the built-in groove 401 under the action of the telescopic spring 403 and pops out and is inserted into the interior of the limit groove 400, so that the placement plate 2 can be positioned. When the drying rack 1 needs to be moved, first hold the operating handle 600, and the rubber ring 601 and the anti-slip stripe 602 play a holding and anti-slip role, so that the drying rack 1 can be easily pushed to move.
