The lifting structure 4 is composed of a T-shaped block 401 and a No. 2 spring 402.

[0024] The frame 101 is shaped like a hollow cube, and a rectangular slot is arranged directly above the frame 101, and two groups of horizontal slots are arranged horizontally on a vertical surface on one side of the frame 101, support blocks 102 are arranged vertically on all four sides directly below the frame 101, an air inlet 103 is arranged horizontally on a vertical surface on one side of the frame 101, and an air outlet 104 is arranged horizontally on a vertical surface at a mirror position on the other side of the frame 101, and sealing strips 105 are arranged around the rectangular slot reserved directly above the frame 101, and this structure can stabilize the internal structure.

[0025] Slide grooves 201 are vertically arranged on both sides of the interior of the frame 101, and the interior of one group of the slide grooves 201 is hollow. The slide grooves 201 are arranged on both sides of a rectangular slot reserved directly above the frame 101. A fixed slider 202 is vertically arranged inside the slide groove 201, and a rectangular through groove is arranged inside the fixed slider 202.
