A slot 24 is formed at each end of one side surface of the lifting frame plate 18. A lead screw motor 19 is fixedly connected to the upper bottom surface of the lifting frame plate 18. The output end of the lead screw motor 19 is connected to one end of a lead screw 20, and the other end of the lead screw 20 extends through to the outside of the lifting frame plate 21.

[0030] In use, after placing the workpiece into the loading slot of the loading box 8, the telescopic motor 2 is started, causing the telescopic rod 3 to push the telescopic rod plate 4 upward. Then, the telescopic rod plate 4 drives the first-stage plate 11 to move upward through the auxiliary guide between the guide plate 10 and the guide groove 7. During the upward movement of the first-stage plate 11, the telescopic motor 2 13 moves upward simultaneously. Through the auxiliary limiting between the limiting plates 16 and the limiting groove 17 on both sides of the guide plate 10, the first-stage plate 11 will not fall off, thus completing the first-stage lifting.

[0031] When assistance is needed for the dual-stage lifting assembly, the lead screw motor 19 is started to rotate the lead screw 20. The screw 20 then rotates, causing the lifting frame plate 21 to move upwards. The auxiliary guide between the clamping plates 25 and the slots 24 on both sides of the lifting frame plate 21 prevents it from shifting during its ascent. As the lifting frame plate 21 moves upwards, the belt plate 31 fixes one side of its belt 29, causing one side of the belt 29 to rotate downwards with the assistance of pulleys 28 and 30, while the other side rotates upwards. This movement, through the belt... The second belt plate 34 drives the third lifting frame plate 22 to move upward. The auxiliary guide between the second plate 36 and the second slot 26 ensures that the third lifting frame plate 22 rises stably without deviation. During the upward movement of the third lifting frame plate 22, the fixed connection between the third belt plate 37 and the second belt 33 drives the fourth pulley 32 and the third pulley 35 to rotate. Then, the side of the second belt 33 closest to the third belt plate 37 moves upward, thereby driving the support plate 23 to move upward through the third belt plate 37 until the support plate 23 abuts against the second-stage frame plate 9, thus completing the auxiliary support for the double-stage lifting assembly and preventing the workpiece that has been raised to its highest position from shaking.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
