[0059] The end of the lever 25 close to the shaft of the lifting cylinder 19 corresponds to the position of the upper push rod 24;

[0060] The lever 25 is tilted, and one end of the lever 25 close to the shaft of the lifting cylinder 19 is tilted upward. A second return spring is provided in the middle of the lever 25 for returning the lever 25 to its original position.

[0061] A slide 26 is slidably connected between the inner cylinder 1 and the outer cylinder 2, and a driving device for driving the slide 26 is provided on the outer cylinder 2. There is one support rod, which is connected to the slide 26. The cross section of the support rod is square. The support rod passes through the table top 5. A support plate 37 for supporting the table top 5 is fixed to the support rod. Two pull rods 27 are fixed to the upper side of the barbecue net 7. The pull rods 27 are located on opposite sides of the barbecue net 7. An anti-pullout block 28 is fixed to the upper end of the pull rod 27. Two arc-shaped slide grooves 29 for cooperating with the upper end of the pull rod 27 are provided on the lower side of the table top 5. A cross bar 30 is rotatably connected to the upper end of the support rod. The rotating grill and the cross bar 30 are hinged at one end away from the support rod. A limiting groove 31 is provided on one side of the outer flange 17 for the rotating grill to be placed in, thereby limiting the rotation of the table top 5.

[0062] The rotating grill includes a telescopic rod 32 with one end hinged to the cross bar 30 .

[0063] The driving device includes a screw 33 located between the inner cylinder 1 and the outer cylinder 2, and a second motor 34 for rotating the screw 33;

[0064] The screw rod 33 and the slide seat 26 are threadedly connected.

[0065] The upper end of the screw 33 is connected to the outer flange 17, and the lower end of the screw 33 passes through the bottom of the outer cylinder 2. The lower end of the screw 33 is fixedly connected to the driven gear 35. The second motor 34 is located outside the outer cylinder 2. The second motor 34 is connected to the driving gear 36, and the driving gear 36 and the driven gear 35 cooperate.

[0066] An outlet 38 for taking out the ash receiving pan 3 is provided on one side of the outer cylinder 2 .

[0067] The outer flange 17 and the outer cylinder 2 are an integrally formed structure.

[0068] Principle of the embodiment:

[0069] Initially, the table top 5 is against the upper side of the inner tube 1, and the telescopic rod 32 is in a contracted state, hanging down in the limiting groove 31. The telescopic rod 32 and the limiting groove 31 play a role in limiting and preventing the table top 5 from rotating. At this time, it can be used as a table. Figure 6 .

[0070] Initially, one side of the push rod 20 is against the side of the limit block 21, and the push rod 20 is in a vertical state. Figure 7 .

[0071] The bottom view of the desktop panel 5 is shown in FIG. Figure 8 .

[0072] Rotate the telescopic rod 32 to make it horizontal, then fix the telescopic rod 32 (using bolts or other means to fix it) and disengage the telescopic rod 32 from the limiting groove 31. Figure 9 .

[0073] Then rotate the tabletop 5 by hand through 180 degrees. (During the rotation, the upper end of the pull rod 27 moves along the sliding groove 29 and finally disengages from the sliding groove 29.) Then extend the telescopic rod 32. The telescopic rod 32 is located above the inner cylinder 1. Things can be strung on the telescopic rod 32 for barbecuing. The barbecued things can be placed on the tabletop 5. Refer to Figure 10 , the driving device moves, controlling the up and down movement of the sliding seat 26, and thus the height of the telescopic rod 32 can be controlled.

[0074] In the initial situation, the driving device operates, and the tabletop 5 moves upward. The telescopic rod 32 disengages from the limit groove 31. Under the action of the support plate 37, the tabletop 5 moves upward. Under the action of the pull rod 27, the barbecue net 7 moves upward, and the lifting cylinder 19 moves upward. When the lower end of the ejector rod 20 exceeds the limit block 21, under the action of the spring, the lower end of the ejector rod 20 rotates by an angle towards the side away from the axis of the lifting cylinder 19. Refer to Figure 11 ;

[0075] Then the driving device stops operating, and the tabletop 5 rotates by 180 degrees. The pull rod 27 disengages from the sliding groove 29. Under the action of the ejector rod 20, the barbecue net 7 does not fall. The barbecue net 7 is located on the upper side of the inner cylinder 1. Refer to Figure 12 , put the roasted meat on the upper side of the barbecue net 7 for barbecuing. After roasting, put the meat on the tabletop 5.

[0076] After barbecuing, rotate the tabletop 5, and the sliding groove 29 cooperates with the upper end of the pull rod 27 again. Then the driving device continues to move upward, and the lifting cylinder 19 continues to move upward. Under the action of the upper push rod 24, the shift lever 25 rotates to the horizontal position and toggles the ejector rod 20, and the ejector rod 20 becomes vertical again. Refer to Figure 13 , then the tabletop 5 moves downward until the lower push rod 23 pushes the shift lever 25, and the shift lever 25 becomes inclined again. The shift lever 25 disengages from the ejector rod 20, and the ejector rod 20 abuts against the limit block 21 again and returns to the initial state.
