In the above two embodiments, since the switching shaft 5 needs to rotate, and the telescopic driving unit 19, the electromagnetic valve, etc. are not fixed, at this time, both the two matching mechanisms can achieve the function, one of them is rotatably connected to a driving part 20 at the end of the switching shaft 5, for example, a cylinder hole is formed at one end of the switching shaft 5 away from the power output shaft, a butting shaft is rotatably sleeved in the cylinder hole, a radial ring is arranged on the butting shaft, a radial groove is formed in the cylinder hole, and the radial ring is matched with the radial groove, so that the axial movement of the butting shaft can drive the switching shaft 5 to axially move, the switching shaft 5 rotates without rotating the butting shaft, and the axial movement of the butting shaft is driven to achieve the switching among the first position, the second position, and the third position. Second, set up a radial lobe on the switching axle 5, and the tip of flexible drive unit 19 passes through the rolling piece and rolls and connect on this radial lobe like the wheel, so no matter how radial lobe is rotatory, this rolling piece all can roll and go to extrude radial lobe, and is corresponding, and the reset of switching axle 5 can be gone on through the spring, and the spring resets for prior art, does not give unnecessary details.

In each embodiment of the present invention, the power required by the driving motor of the driving mechanism 4 is relatively large, and especially the expected weight of the second drawer 3 for carrying bowls and dishes is relatively large, generally reaching 7kg or more, and partially even reaching 15kg or more, based on which the power required to be configured by the driving motor is relatively large, but the telescopic driving unit 19 and the electromagnetic valve for driving the switching shaft 5 to reciprocate only need to drive one switching shaft 5, and the power is relatively small, so that the micro motor (the motor with a diameter less than 160mm or a rated power less than 750W) is sufficient, and therefore, even if two driving units are present, the number of driving units for driving the drawers in the prior art is not an order of magnitude, and the cost is still greatly reduced.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
