When it is necessary to take out items in the specified storage box, the corresponding movable plate is manually driven to move away from the support plate, so that the limit block is disengaged from the limit groove, releasing the limit on the position of the slide plate and the storage box, so that the slide plate can slide in the first slide groove, and at the same time the movable plate contacts the switch, and the switch controls the electromagnets on other storage boxes to cut off the power, so that the electromagnets and the iron plate are no longer magnetically attracted together, and at the same time the electromagnets on the corresponding storage box are energized, so that the electromagnets and the iron plate are magnetically attracted together.

When there is no need to take the items in the storage box, the rotary drive mechanism drives the rotating shaft to rotate in the opposite direction, so that the storage box is reset to the initial position, and the connecting plate is manually driven to move up, so that the second baffle is no longer located on one side of the movable plate, and the limitation on the position of the movable plate is released. The second compression spring drives the movable plate and the limit block to move, so that the limit block is again inserted into the corresponding limit slot, so that the storage box can be fixed relative to the support plate;

[0017] (3) The motor drives the gear to rotate, and the gear drives the gear ring to rotate, so that the shaft can rotate. The first baffle is manually driven to move downward, so that the first baffle is no longer located on one side of the motor box. The first compression spring is in a compressed state, and the position restriction of the motor box is released. The motor box is manually driven to move away from the shaft, so that the slider slides out of the second slide groove, and the gear is no longer engaged with the gear ring, and the motor can be removed.

The second baffle plate 31 is no longer located on one side of the movable plate 14, and the position restriction of the movable plate 14 is released. The second compression spring 30 drives the movable plate 14 and the limit block 13 to move, so that the limit block 13 is inserted into the corresponding limit slot 11 again, and the storage box 7 does not need to be pulled all the time. When there is no need to take out the items in the storage box 7, the rotation drive mechanism drives the rotating shaft 5 to rotate in the opposite direction, so that the storage box 7 is restored to its initial position, and the connecting plate 33 is manually driven to move up, so that the second baffle plate 31 is no longer located on one side of the movable plate 14, and the position restriction of the movable plate 14 is released. The second compression spring 30 drives the movable plate 14 and the limit block 13 to move, so that the limit block 13 is inserted into the corresponding limit slot 11 again, and the storage box 7 can be stored.

The first baffle 24 is manually driven to move downward, so that the first baffle 24 is no longer located on one side of the motor box 17. The first compression spring 27 is in a compressed state, and the limitation on the position of the motor box 17 is released. The motor box 17 is manually driven to move away from the rotating shaft 5, so that the slider 23 slides out of the second slide groove 22, and the gear 20 is no longer engaged with the gear ring 18, and the motor 19 can be removed. Through the design of the fixed sleeve 36, the movable column 37 and the buffer spring 38, the buffer plate 35 is elastically connected to the main body 1.
