[0024] Specifically, after the upper support plate 1 is squeezed, the push rod 4 is driven to rotate through the first fixed shaft 3, thereby pushing the sliding column 5 to slide on the outer wall of the fixed column 8 through the second fixed shaft 6. The first spring 7 is compressed after being subjected to force, and at the same time, the second spring 11 is squeezed through the fixed seat 2. Through the rebound of the first spring 7 and the second spring 11, the effect of buffering is achieved after the upper support plate 1 is subjected to force.

[0025] Reference Figure 1 and Figure 3 , the lower surface of the storage box 9 is slidably connected with a retaining ring 14, the outer wall of the retaining ring 14 is provided with a flat PTFE plate 15, the lower surface of the retaining ring 14 is slidably connected with a lower support plate 12, the outer wall of the lower support plate 12 is provided with a spherical plate 13;

[0026] Specifically, the design of the retaining ring 14 , the flat PTFE plate 15 , the spherical plate 13 and the lower support plate 12 can better play a supporting role.

[0027] Reference Figure 2-Figure 4 The inner thread of the storage box 9 is connected to a threaded rod 16, and the upper surface of the threaded rod 16 is fixedly connected to a handle 17. The outer wall of the threaded rod 16 is threadedly connected to a fixing plate 28. The outer wall of the fixing plate 28 is fixedly connected to the limit block 18. The outer wall of the limit block 18 is slidably connected to the sleeve 27. The outer wall of the fixing plate 28 is fixedly connected to the first fixing block 19.

[0028] Specifically, the rotating handle 17 drives the fixing plate 28 to rise and fall through the threaded rod 16. The limiting block 18 limits the fixing plate 28. The fixing plate 28 drives the first rotating shaft 20 to push the rotating rod 21 to rotate through the first fixed block 19, and drives the second rotating shaft 22 inside the second fixed block 23 to rotate. The push plate 24 can be opened from the outer wall of the sleeve 27 through the third rotating shaft 25 for installation and fixation.

[0029] Working principle: When the support is needed, the storage box 9 is placed on the upper surface of the retaining ring 14, and the handle 17 is turned. The handle 17 will drive the fixing plate 28 to rise and fall, and the fixing plate 28 is limited by the limit block 18. After being subjected to force, the fixing plate 28 will only slide inside the sleeve 27 without rotating. The fixing plate 28 will drive the rotating rod 21 to rotate through the first rotating shaft 20 inside the first fixing block 19. When the rotating rod 21 rotates, it will drive the second rotating shaft 22 to rotate inside the second fixing block 23, thereby pushing the push plate 24 to open from the outer wall of the sleeve 27 through the internal third rotating shaft 25. When the storage box 9 and the retaining ring 14 are aligned, the handle 17 is turned to push the opened push plate 24 out The interior of the retaining ring 14 is expanded to facilitate installation and fixation, which is convenient for use. The upper support plate 1 will be pressed downward after being subjected to force, thereby pushing the push rod 4 to rotate through the first fixed shaft 3 inside the fixed seat 2. When the push rod 4 rotates, it will push the sliding column 5 to slide on the outer wall of the fixed column 8 through the second fixed shaft 6, thereby squeezing the first spring 7. The first spring 7 is compressed after being squeezed. At the same time, the upper support plate 1 will be subjected to force and squeeze the second spring 11 through the fixed seat 2. The first spring 7 and the second spring 11 rebound after being free from force, thereby achieving the effect of buffering the upper support plate 1 after it is subjected to force. This support can not only achieve the effect of convenient installation, but also achieve the effect of buffering after being subjected to force, thereby extending the service life.
