[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Loosen the bolt to make the upper end of the bolt detach from the lifting platform, then drag the bolt to drive the turnbuckle to rotate, so that the turnbuckle and the guide column are disengaged, and then adjust the height of the lifting platform. Use the booster spring to reduce the gravity effect of the lifting platform and the turnbuckle to facilitate the adjustment of the height of the lifting platform.

[0016] 2. Use the elastic force of the booster spring to act upward on the sliding sleeve to alleviate the gravity of the lifting platform and the turnbuckle and reduce the difficulty of adjustment.

[0017] 3. Use the four corners of the rotating frame to embed in the card slot, and use the rotating frame to act on the lower end of the platform to maintain the height of the lifting platform; turn the four corners of the rotating frame away from the card slot to disengage the guide column and the rotating buckle, which is convenient for locking or unlocking the lifting platform.
