[0021] In this specific embodiment, the top plate 2 is disposed above the bottom plate 1, the support box 3 is disposed between the top plate 2 and the bottom plate 1, the guide mechanism is disposed above and below the support box 3, the first connecting rod 7 is rotatably connected to the bottom plate 1 and located below the support box 3, the second connecting rod 8 is rotatably connected to the top plate 2 and located above the support box 3, two first sprockets 5 are fixedly connected to the first connecting rod 7 and are respectively disposed on both sides of the first sprocket 5, two second sprockets 6 are fixedly connected to the second connecting rod 8 and are respectively disposed on both sides of the second connecting rod 8, and two chains... Both ends of the chain 9 are fixedly connected to the support box 3 and respectively cover the surfaces of the corresponding first sprocket 5 and second sprocket 6. The two chains 9 are respectively arranged on both sides of the support box 3. The drive assembly is arranged on one side of the first connecting rod 7. The drive assembly drives the first connecting rod 7 to rotate, so that the two first sprockets 5 rotate accordingly. Under the action of the second sprocket 6 of the second connecting rod 8, the chain 9 drives the support box 3 to move accordingly. Under the action of the second connecting rod 8 and the second sprocket 6, the chains 9 on both sides move accordingly, ensuring that the two sides of the support box 3 move the same distance, thus improving stability.

[0022] The four guide rods 10 are fixedly connected at both ends to the bottom plate 1 and the top plate 2, respectively, and are disposed outside the support box 3. The four sliding blocks 11 are fixedly connected to the support box 3 and respectively cover the surface of the four guide rods 10. The four support components are respectively disposed at the lower end of the corresponding guide rods 10. When the support box 3 moves, the sliding blocks 11 move on the surface of the guide rods 10, thereby improving the stability of the support box 3.

[0023] Secondly, the driven wheel 12 is fixedly connected to the first connecting rod 7 and is located in the middle section of the first connecting rod 7.

The spring 17 covers the surface of the guide rod 10 and is located between the support block 15 and the fixing block 16. The fixing block 16 drives the top plate 2 to move. When the support box 3 moves down, the support block 15 supports the sliding block 11, and the spring 17 contracts accordingly. At the same time, the fixing block 16 and the support block 15 restrict the position of the sliding block 11 to prevent the support box 3 from contacting the first sprocket 5.

[0025] In addition, the four limiting blocks 4 are fixedly connected to the top plate 2 and located above the support box 3. The four limiting blocks 4 restrict the position of the support box 3 and prevent the support box 3 from contacting the second sprocket 6.

[0026] When using this utility model, the motor 18 drives the drive wheel 13 to rotate, the drive wheel 13 drives the driven wheel 12 to move, causing the first rotating rod to rotate accordingly, causing the two first sprockets 5 to rotate accordingly. Under the action of the second sprocket 6 of the second connecting rod 8, the chain 9 drives the support box 3 to move accordingly. Under the action of the second connecting rod 8 and the second sprocket 6, the chains 9 on both sides move accordingly, ensuring that the two sides of the support box 3 move the same distance. When the support box 3 moves, the sliding block 11 moves on the surface of the guide rod 10, improving the stability of the support box 3.
