[0002] The high-rib spiral staircase is a typical spiral staircase structure, commonly seen inside buildings or outdoor landscapes. Its characteristic is that the spiral staircase plate rotates upward around the central axis. It is usually made of materials such as metal, wood or stone. The design of the high-rib spiral staircase has a strong sense of aesthetics and space, which can add visual impact and artistic sense to the building.

[0021] refer to Figure 3 and Figure 4 As shown, the inner cavity of the clamping block 14 is fixedly connected with a threaded sleeve 15, and an adjusting rod 18 is threadedly connected between the inner cavities of the two threaded sleeves 15. Both sides of the clamping block 14 are fixedly connected with a slide seat 17, and the surface of the slide seat 17 is movably connected to the inner cavity of the slide rail 12. Both sides of the connecting shell 11 are fixedly connected with a positioning block 16, and the bottom of the positioning block 16 is fixedly connected to the bottom of the inner cavity of the connecting groove. Three second springs 9 are fixedly connected to both sides of the bottom of the inner cavity of the connecting groove, and a reset plate 10 is fixedly connected between the tops of the three second springs 9. Both sides of the bottom of the bottom plate 3 are fixedly connected with an extrusion plate 6, and the bottom of the extrusion plate 6 contacts the reset plate 10. Both sides of the front and rear sides of the bottom of the bottom of the bottom plate 3 are fixedly connected with an insertion block 7, and the surface of the insertion block 7 is movably connected to the inner cavity of the insertion shell 8.

[0022] It should be noted that: through the threaded sleeve 15 and the adjusting rod 18, the staff can easily remove the base plate 3 and the pedal 4; by setting the sliding seat 17, the blocking block 14 is limited; by setting the positioning block 16, the connecting shell 11 is positioned; by setting the second spring 9 and the reset plate 10, the base plate 3 can be ejected; by setting the extrusion plate 6, the reset plate 10 can be squeezed; and by setting the insert block 7, the base plate 3 can be limited.

[0023] Working principle: When the staff needs to install the staircase on the high-ribbed spiral staircase body 1, first the bottom plate 3 drives the stepping plate 4 to be placed on the top of the connecting seat 2. At this time, the card plate 5 will be inserted into the inside of the connecting shell 11, and the inclined surface at the bottom of the card plate 5 will contact the inclined surfaces of the two card blocks 14.
