[0052] Taking: When opening the door, pull out the two pull rods 3, the amount of light received by the photoresistor installed on the pull rod 3 is reduced, the resistance is reduced, the main circuit current increases, and the current passing through the electromagnetic relay 1901 increases. The electromagnetic relay 1901 has the same magnetic properties as the fixed block 1903, thereby pushing the fixed block 1903 to slide along the pull rod 3 in the direction away from the electromagnetic relay 1901, thereby unlocking;

[0053] The hydraulic cylinder 11 drives the rotating shaft 10 to rise, and the first hinged rod 6 and the second hinged rod 12 slide in the direction of approaching each other, thereby driving the steel plate 5 and the holding rack 4 to be lifted to the desired position, making it convenient to take the tableware; after taking the tableware, the hydraulic cylinder 11 drives the rotating shaft 10 to descend, and the first hinged rod 6 and the second hinged rod 12 slide in the direction of moving away from each other, thereby driving the steel plate 5 and the holding rack 4 to be descended to the desired position.
