[0017] In this embodiment, the fixing column 2 is firstly driven by the threaded fastener to be installed at the uphill and downhill parts of the stair main body 1, so that the entire building safety protection structure is installed on the stair main body 1, and then the toggle lever 1106 in the threaded adjustment mechanism 11 is operated to rotate, so that it drives the second bevel gear 1105 to rotate, and the second bevel gear 1105 drives the pair of first bevel gears 1104 to rotate through the meshing transmission action, so as to promote the synchronous rotation of the pair of threaded rods 1102, and the pair of thick-walled sleeves 1103 move toward or away from each other with the synchronous rotation of the pair of threaded rods 1102 under the action of the internal threads, and then the pair of thick-walled sleeves 1103 are rotated. 03 drives a pair of fixed sleeve blocks 7 and movable guard plates 6 to move synchronously, and at the same time, a pair of moving rods 1201 in the auxiliary sliding assembly 12 also slide synchronously with the pair of fixed sleeve blocks 7 and movable guard plates 6, so as to assist the movement of the pair of fixed sleeve blocks 7 and movable guard plates 6, and the pair of movable guard plates 6 will also drive a pair of moving blocks 9 to move toward or away from each other along the inside of the accommodating groove 10, thereby driving the distance between the pair of fixed sleeve blocks 7 and movable guard plates 6 and the fixed guard plates 3 to be adjusted accordingly according to the construction and use requirements on site, thereby realizing the protection height adjustment, so as to enhance its protection effect.
[0018] See also Figures 2-6, a number of screw adjustment mechanisms 11 each include two pairs of partition plates 1101 installed inside the right connection frame 4, and a threaded rod 1102 is threadedly connected between a pair of partition plates 1101. The closer ends of a pair of threaded rods 1102 are fixedly connected with a first bevel gear 1104 respectively, and a second bevel gear 1105 is meshed and connected between the front ends of a pair of first bevel gears 1104. The front end of the connection frame 4 on the right is rotatably connected with a toggle rod 1106, and the rear end of the toggle rod 1106 is fixedly connected with the front end of the second bevel gear 1105. The outer ends of a pair of threaded rods 1102 are each sleeved with a thick-walled sleeve 1103.

[0019] In this embodiment, the toggle rod 1106 is rotated to drive the second bevel gear 1105 to rotate. The second bevel gear 1105 drives a pair of first bevel gears 1104 to rotate through meshing transmission, prompting a pair of threaded rods 1102 to rotate synchronously. Under the action of the internal thread, a pair of thick-walled sleeves 1103 move towards or away from each other with the synchronous rotation of a pair of threaded rods 1102. Then a pair of thick-walled sleeves 1103 drive a pair of fixed sleeve blocks 7 and the movable guard plate 6 to move synchronously, realizing driving a pair of fixed sleeve blocks 7 and the movable guard plate 6 to adjust the distance from the fixed guard plate 3, so as to adjust the protection height.
[0020] Please refer to Figure 6 , the inner wall of the thick-walled sleeve 1103 is provided with an internal thread, and the thick-walled sleeve 1103 is threadedly connected with the threaded rod 1102 through the internal thread.
[0021] In this embodiment, through the setting of the internal thread, the inner wall of the thick-walled sleeve 1103 is threadedly connected with the threaded rod 1102, so that when the threaded rod 1102 rotates, the thick-walled sleeve 1103 can be driven to move up and down through the meshing of the internal thread and the thread on the threaded rod 1102.
[0022] Please refer to Figure 3 , a number of uniformly distributed anti-slip strips 11061 are fixedly connected to the outer end of the toggle rod 1106.
[0023] In this embodiment, through the setting of the anti-slip strips 11061, it is not easy for the staff to slip when rotating the toggle rod 1106, improving the operation stability.
[0024] Please refer to Figures 4-5, a plurality of auxiliary sliding components 12 each include a pair of moving rods 1201 fixedly connected to the closer ends of a pair of fixed sleeve blocks 7 respectively. Second through holes are formed at both the upper and lower ends of the connecting frame 4 on the left side. And the closer ends of the pair of moving rods 1201 both pass through the second through holes and extend into their interiors. A pair of sliding rods 1202 are fixedly connected to the outer ends of the pair of moving rods 1201. Two pairs of sliding grooves 1203 are formed on the inner wall of the connecting frame 4 on the left side. And the pair of sliding rods 1202 are respectively located in the two pairs of sliding grooves 1203 and are slidably connected thereto.
[0025] In this embodiment, the pair of moving rods 1201 move synchronously with the pair of fixed sleeve blocks 7 and the movable guard plate 6, driving the two pairs of sliding rods 1202 to slide synchronously in the two pairs of sliding grooves 1203 respectively, realizing the auxiliary movement of the pair of fixed sleeve blocks 7 and the movable guard plate 6, and keeping the pair of fixed sleeve blocks 7 and the movable guard plate 6 moving stably.
[0026] Please refer to Figure 6 , sealing rings are fixedly connected to the inner walls of the first through hole and the second through hole, and the inner walls of the two sealing rings are in close contact with the thick-walled sleeve 1103 and the moving rod 1201 respectively.
[0027] In this embodiment, through the setting of the sealing rings, the gaps between the thick-walled sleeve 1103 and the first through hole and between the second through hole and the moving rod 1201 can be sealed respectively, making it difficult for dust to enter the interior of the connecting frame 4 and enhancing the sealing and dust-proof effect.
