When the dish spoon 81 moves out upwards to be above the upper plane of the dinner plate mounting plate 22, the connecting plate 33 presses and contacts the press-contact switch 44, so that the electric telescopic rod 41 is started, the tray plate 42 is pushed forwards, the dish box 43 above the tray plate is just positioned below the dish spoon 81, at the moment, the connecting plate 33 is disconnected from the press-contact switch 44, the upper edge of the circular arc wall of the dish spoon 81 just touches the lower surface of the press-contact plate 45 at the moment, the connecting plate 33 continues to rise, the dish spoon 81 also continues to rise, at the moment, the upper edge of the circular arc wall of the dish spoon 81 is stressed, the dish spoon is turned downwards, a concave surface with a downward opening is formed, namely, the dish placing shape is formed, dishes fall into the dish box 43 below the dish spoon 81, at the moment, the connecting plate 33 runs to the highest point, and stops rising.

The working principle or the using method is as follows:

in the initial state, the telescopic rod 311 of the lifting unit 3 is in the tightened state, the spoon 81 is at the top and in the dish placing state, and the dish plate 4 is in the extended state.

The person of serving places dish box 43 on tray portion 42, then the person of serving presses the button of serving, the terminal passes through face identification, carry out big data comparison, it reachs the amount of dish that this person is fit for using, aerify or bleed through to amount of dish control gasbag 82, make amount of dish control gasbag 82 inflation or reduce, make the inside spatial variation of dish spoon 81, thereby the control is how much of serving at every turn, then telescopic link 311 on the lift portion 3 is released downwards, make connecting plate 33 slide down, press and touch compression switch 44, make electric telescopic handle 41 start, the backward retraction, make tray portion 42 leave the dish spoon 81 below, make dish spoon 81 can pass through the hole on dish portion mounting panel 22.

When the spoon 81 is located above the dish plate portion mounting plate 22, the upper end of the sliding base 62 is pressed against the bottom surface of the dish plate portion mounting plate 22, the sliding shaft 661 and the sliding shaft 662 on the lifting shaft assembly 66 are in an extended state, the third spring 663 is compressed, the sliding shaft 661 retracts into the sliding shaft 662 during the downward movement of the connecting plate 33, the third spring 663 slowly recovers, after the spoon 81 completely passes through the dish plate portion mounting plate 22, the lifting shaft assembly 66 finishes retracting, the lifting shaft assembly 66 starts to move downward integrally, so that the sliding base 62 moves downward to drive the leveling sliding block 63 to move downward together, during the downward movement, the rolling wheel 65 at the tail end of the leveling sliding block 63 is pressed against the inclined pushing plate 61 under the action of the fourth spring 64, and the inclined pushing plate 61 tilts from top to bottom, so that the leveling sliding block 63 retracts backward, after the spoon 81 enters the dish bucket 563, the sliding base 62 is pressed against the lifting block of the dish bucket base 58, and the lift shaft assembly 66 continues downward.

After the vegetable spoon 81 enters the vegetable barrel 563, the telescopic rod 311 extends continuously, so that the vegetable spoon 81 is pressed downwards to contact the arc-shaped head 513 on the lifting rotating head 51, and the lifting rotating head 51 slides downwards, and in the process of sliding downwards, the lifting rotating head 51 rotates under the action of the guide steel ball 53 and the sliding slot 511, because the lifting rotating head 51 is connected with the sliding hexagonal shaft 50 in a sliding manner through the middle hole 512, the sliding hexagonal shaft 50 is driven to rotate when the lifting rotating head 51 rotates, because the bottom of the sliding hexagonal shaft 50 is arranged on the threaded disc 55 in a single-rotation manner, the threaded disc 55 is driven to rotate, because the long groove 562 on the internal threaded sleeve 566 is arranged in a matching manner with the guide plate 582, the internal threaded sleeve 566 cannot rotate, and therefore the threaded disc 55 rotates, the internal threaded sleeve 566 is driven to slide upwards, so as to drive the whole vegetable storage barrel 56 to slide upwards, and the top surface of vegetables in the vegetable barrel 563 exceeds the top surface of the arc-shaped head 513, at this time, the outer edge of the arc surface of the spoon 81 contacts the upper top surface of the guiding stop collar 59, and the guiding stop collar continues to slide downwards, so that the arc surface of the spoon 81 is turned upwards to form an upward-opening concave surface, i.e. a dish-making shape, during the whole process of turning upwards, the dish storage barrel 56 slides upwards, the top surface of the dishes in the dish barrel 563 exceeds the top surface of the arc surface head 513, so that the dishes in the dish barrel 563 enter the spoon 81, the telescopic rod 311 on the lifting part 3 slides downwards to the lowest end and then starts to lift upwards, the lifting rotating head 51 returns to the initial state under the action of the first spring 52, the dish barrel 563 presses downwards to contact the second spring 57 due to the action of the dishes and the self gravity, at this time, the dishes in the dish barrel 563 have been reduced by a part, so that the descending distance is smaller than the ascending distance, and therefore, the inner thread sleeve 566 drives the thread plate 55 to rotate by an angle smaller than the rotating angle of the sliding shaft 50, while the rotation of the threaded disk 55 and the rotation of the sliding hexagonal shaft 50 are completed almost at the same time, the threaded disk 55 and the sliding hexagonal shaft 50 are provided for single rotation, so that the sliding hexagonal shaft 50 does not have a seized state between them at more rotation angles than the threaded disk 55.

The telescopic rod 311 on the lifting part 3 slides upwards to drive the connecting plate 33 to slide upwards, so as to drive the supporting rod 83 and the lifting shaft assembly 66 to slide upwards at the same time, after the dish spoon 81 slides upwards for a certain distance, the upper surface of the limiting bump 664 at the bottom of the sliding sleeve shaft 662 is pushed against the bottom surface of the sliding base 62, at this time, the left push plate 631 and the right push plate 632 are just flush with the upper push surface of the circular arc wall of the dish spoon 81, at this time, the connecting plate 33 continues to slide upwards to drive the dish spoon 81 and the sliding base 62 to ascend together, because the rolling wheel 65 is pushed against the inclined push plate 61, when the sliding base 62 drives the pushing sliding block 63 to slide upwards, the rolling wheel 65 is pushed against the inclined push plate 61, so as to push the pushing sliding block 63 to slide forwards, so as to push away the dishes on the dish spoon 81 exceeding the upper top surface, so that the dishes in the dish spoon 81 are just the volume of the dish spoon 81, and after the pushing sliding block 63 completely pushes the dish spoon 81, the upper end of the sliding base 62 contacts the bottom surface of the dish plate mounting plate 22, and at this time, the connecting plate 33 continues to slide upwards, and the sliding base 62 does not rise, so as to pull the sliding shaft 661 to slide upwards, and the gap between the left guide shaft 633 and the right guide shaft 634 is larger than the diameter of the spoon 81, so that the spoon 81 can also pass through the left guide shaft 633 and the right guide shaft 634 without touching, and thus move upwards to the upper end of the dish plate mounting plate 22.

After the dish spoon 81 moves out upwards to be above the upper plane of the dinner plate mounting plate 22, the connecting plate 33 presses the press-touch switch 44, so that the electric telescopic rod 41 is started, the tray plate 42 is pushed forwards, the dish box 43 above the tray plate is just positioned below the dish spoon 81, at the moment, the connecting plate 33 is disconnected from the press-touch switch 44, the upper edge of the circular arc wall of the dish spoon 81 just touches the lower surface of the press-touch plate 45, at the moment, the connecting plate 33 continuously rises, the dish spoon 81 also continuously rises, at the moment, the upper edge of the circular arc wall of the dish spoon 81 is pressed, the dish spoon is turned downwards, a concave surface with a downward opening is formed, namely, the dish placing shape is formed, dishes on the dish spoon fall into the dish box 43 below, at the moment, the connecting plate 33 runs to the highest point, and stops rising.
