[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: A motor-driven automatic lifting device, such as Figures 1-2 As shown, the device includes a motor 2, characterized in that: a lead screw 21 is provided on the output end of the motor 2; a mounting base 1 is sleeved on the bottom of the motor 2; a mounting shell 13 is sleeved on the top of the mounting base 1; the mounting shell 13 is sleeved on the surface of the motor 2; a slide block 3 is provided on the top of the mounting shell 13 corresponding to the protruding part of the lead screw 21; an inner cavity 32 for inserting the lead screw 21 is provided inside the slide block 3; a limiting cavity 33 communicating with each other is provided on the left and right sides of the inner cavity 32; a sliding sleeve 34 is rotatably sleeved on the surface of the lead screw 21; a limiting piece 35 is provided on both sides of the sliding sleeve 34; the limiting piece 35 is provided above the limiting cavity 33 on both sides; the sliding sleeve 34 is slidably disposed in the inner cavity 32; a telescopic rod 36 is provided on the top of the sliding sleeve 34; a cover 37 is provided on the top of the slide block 3; the top of the telescopic rod 36 extends out of the inner cavity 32 through the cover 37; and the top of the telescopic rod 36 is inserted into the bottom of the push-pull rod 4.

[0016] The top inner ring of the mounting base 1 has an inner edge 11, and buckles 12 are provided on both sides of the inner edge 11. The bottom outer ring of the mounting shell 13 has a corresponding slot 131 for the buckles 12. This makes it easier to install the mounting base 1 and the mounting shell 13, and also makes it easier to disassemble and repair them later.

[0017] A reinforcing base 14 is provided on the top of the mounting shell 13 corresponding to the outer ring of the slide 3. Multiple reinforcing ribs 142 are provided between the outer ring of the reinforcing base 14 and the mounting shell 13. A positioning piece 141 is provided on one side of the reinforcing base 14. A back frame 31 is provided on one side of the slide 3 above the positioning piece 141. The back frame 31 is engaged downwards by the positioning piece 141, making the installation of the slide 3 on the top of the mounting shell 13 more stable. At the same time, the positioning piece 141 clamps the back frame 31 on the rear side of the reinforcing base, which, together with the reinforcing base 14, makes the installation straighter and reduces sliding friction.

[0018] The principle of this utility model is as follows: when the motor 2 is turned on, it drives the lead screw 21 to rotate. The sliding sleeve 34 sleeved on the surface of the lead screw 21 moves upward along the inner cavity 32 of the slide block 3. At the same time, the limiting pieces 35 on both sides of the sliding sleeve 34 slide synchronously in the two limiting cavities 33 that communicate with the inner cavity 32. The sliding sleeve 34 rises and extends out of the top of the cover 37, driving the top push rod to be pushed upward.
