[0024] The moving mechanism includes a first bevel gear 9, which is located inside the scaffolding body 1 and is rotatably connected to the scaffolding body 1 through a bearing. An inner hexagonal groove is provided inside the top of the first bevel gear 9, and both ends of the first bevel gear 9 are meshedly connected with second bevel gears 10. A transverse threaded rod 11 is fixed to the end of the second bevel gear 10 away from the first bevel gear 9, and a first transverse sliding plate 5 is threadedly connected to the outer side of the transverse threaded rod 11. The first transverse sliding plate 5 is located inside the scaffolding body 1 and is slidably connected to the scaffolding body 1.

Transverse light rods 12 are fixed on both sides of the inside of the scaffolding body 1, and the transverse light rods 12 pass through the inside of the first transverse sliding plate 5 and are slidably connected to the first transverse sliding plate 5.

[0025] The protection plate 3 is internally slidably connected with a second transverse sliding plate 6, which is close to one end of the protection extension plate 4 and fixedly connected to the protection extension plate 4.
