A repulsive force is generated between the shelf 300 and the door 200, and the carrier bar 310 moves backward in the horizontal section 222 into the vertical section 221, so that the shelf 300 moves backward. The bearing rods 310 are carried on the support bars 522 on the sliding blocks 521, and the height of the shelf 300 is adjusted to the corresponding horizontal section 222.

The second magnetic unit 420 at the rear side of the cabinet door 200 is powered off by the touch switch, and attractive force is generated between the second magnetic unit 420 and the first magnetic unit 410 at the front side of the shelf 300. An attractive force is generated between the shelf 300 and the door 200, and the loading bar 310 moves forward to the front end of the horizontal section 222, so that the shelf 300 moves forward until the front side of the shelf 300 is fitted on the rear side of the door 200.

When the carrier bar 310 is supported on the support rib 522, the elastic force of the elastic member 530 can support and buffer the movement of the shelf 300, so that the shelf 300 can be smoothly performed when the height is adjusted. When the carrier rod 310 is carried on the supporting rib 522, the carrier rod 310 is pressed on the limiting buckle 540, and the limiting buckle 540 and the limiting hook 550 are separated, so that the sliding block 521 can move up and down. When the carrier rod 310 is separated from the support rib 522, the carrier rod 310 is separated from the limit buckle 540, and the limit buckle 540 is clamped with the limit hook 550, so that the support piece 520 is limited at a preset height, and the carrier rod 310 can move onto the support rib 522 when the height of the shelf 300 needs to be adjusted.
