[0040] Example 2

[0041] Reference Figures 1 to 6 , which is the second embodiment of the present utility model. Different from the previous embodiment, it further includes a locking assembly 200. The locking assembly 200 is arranged on one side of the mounting component 106. The locking assembly 200 includes a protrusion 201 arranged on one side of the mounting component 106, a groove 202 arranged on the side of the protrusion 201 close to the fixing component 105, and a locking component 203 arranged inside the groove 202. The protrusion 201 is arranged on the side of the mounting component 106a away from the support plate 101, and the protrusion 201 is provided with a groove 202 on the side close to the first steel frame 105a. The locking component 203 is arranged inside the groove 202. The locking component 203 includes a threaded rod 203a arranged through the groove 202, and a nut 203a-1 is provided on the threaded rod 203a.

[0042] Furthermore, a first locking block 203b is provided inside the groove 202, an adjustment groove 203b-1 is provided on the first locking block 203b, a first clamp 203b-2 is provided on the side of the first locking block 203b away from the adjustment groove 203b-1, a second locking block 203b-3 is provided in the adjustment groove 203b-1, and a second clamp 203b-4 is provided on the side of the second locking block 203b-3 away from the nut 203a-1.

[0043] Specifically, the protrusion 201 is set on the side of the mounting member 106a away from the support plate 101, and the protrusion 201 is provided with a groove 202 on the side close to the first steel frame 105a. The groove 202 is inclined, and the first locking block 203b and the second locking block 203b-3 are provided inside the groove 202. The first locking block 203b and the second locking block 203b-3 are inclined and fit the side wall of the groove 202. The first locking block 203b is provided on the side close to the first steel frame 105a. The first grabbing clamp 203b-2 cooperates with the first steel frame 105a, and the second locking block 203b-3 is provided with a second grabbing clamp 203b-4 on the side close to the first steel frame 105a and cooperates with the first steel frame 105a. An adjustment groove 203b-1 is provided on the first locking block 203b, and the second locking block 203b-3 is provided with a flat plate on the side close to the adjustment groove 203b-1 to move in the adjustment groove 203b-1 and will not be out of cooperation with the adjustment groove 203b-1 due to the influence of the side wall of the groove 202.

[0044] Specifically, a threaded rod 203a is provided through the protrusion 201 and is fixedly connected to the first locking block 203b. A nut 203a-1 is provided on the threaded rod 203a to adjust the position of the first grabbing clip 203b-2 and the second grabbing clip 203b-4. First, the mounting component 106 is installed on the second steel frame 105b. At this time, the mounting component 106 can be displaced in the vertical direction on the second steel frame 105b. The specific method is as in Example 1. It is important that when the clamping plate 106b-1 is rotated to the locking state, the position of the groove 202 is directly above the first steel frame 105a. At this time, the mounting component 106 is displaced downward to adjust the first grabbing clip 203b-2 and the second grabbing clip 203b-4. When the position is level with the first steel frame 105a, the first locking block 203b is driven to move upward by pulling the threaded rod 203a up and down. At this time, the first locking block drives the second locking block 203b-3 to move upward together. At this time, the flat plate on the second locking block 203b-3 shrinks in the adjustment groove 203b-1 and moves toward the side of the first locking block 203b. At this time, the first grabbing clamp 203b-2 and the second grabbing clamp 203b-4 begin to shrink toward each other due to the force of the first locking block 203b and the second locking block 203b-3, thereby clamping the first steel frame 105a. Then, the nut 203a-1 is rotated to form a lock to prevent the first grabbing clamp 203b-2 and the second grabbing clamp 203b-4 from loosening.

[0045] Example 3

[0046] Reference Figures 1 to 7, which is the third embodiment of the present invention, further provides a stair protection device, including a protection module 300 , which is disposed on the support plate 101 and includes a surrounding block 301 and an anti-slip mat 302 disposed on the surface of the surrounding block 301 .

[0047] Furthermore, a block 301 is provided on the support plate 101. The block 301 is configured to form an inward depression by protruding the outer side of the support plate 101, so that when the workers drop objects, they can fall into the depression of the support plate 101, and there will be no safety hazards caused by the falling of heavy objects. An anti-slip pad 302 is provided on the surface of the block 301 to prevent workers from slipping when stepping on the support plate 101.

[0048] Specifically, the anti-slip pad 302 is processed on the support plate 101 to form multiple concave and convex shapes, but the overall shape is horizontal. When the support plate 101 is horizontal, it can also ensure that the friction on the soles of the workers' feet is increased.
