[0022] The following will further describe the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0023] An embodiment of the present application discloses an adjustable temporary guardrail for stairs. Referring to Figures 1-3 , an adjustable temporary guardrail for stairs includes a protective rod 5, a support rod 9 and a pre-installed part 10. The bottom of the support rod 9 is movably installed with the pre-installed part 10. The surface of the pre-installed part 10 is movably installed with a fixing bolt 11. One side of the support rod 9 is movably installed with a fixing rod 7. An inner part of the support rod 9 is provided with a movable groove 8. An inner part of the movable groove 8 is movably installed with a movable block 13. One end of the movable block 13 is movably installed with a limit rod 1. The periphery of the limit rod 1 is movably installed with the protective rod 5. A rotating shaft ring 501 is installed between the protective rod 5 and the limit rod 1. One side of the protective rod 5 is fixedly connected with a clamping block 2. The other side of the protective rod 5 is fixedly connected with a spring buckle 12. The top of the support rod 9 is movably installed with a fixing block 6. Both sides of the bottom of the fixing block 6 are fixedly connected with magnetic attraction rods 601.

[0024] The staff fixes and installs the pre-installed part 10 on the building stair structure. By inserting the support rod 9 into the pre-installed part 10 and screwing the fixing bolt 11 into the space between the pre-installed part 10 and the support rod 9, the support rod 9 and the pre-installed part 10 can be fixed. Then, the movable block 13 is embedded into the inner part of the movable groove 8, and the fixing block 6 is installed on the top of the support rod 9, so that the magnetic attraction rods 601 are adsorbed and connected to the support rod 9 made of a metal material. When the movable block 13 is adjusted to a suitable installation height, the fixing rod 7 is screwed into the inner part of the movable block 13 to limit the position of the movable block 13. The staff can freely pull the protective rod 5 according to the stair angle. The protective rod 5 is rotated and adjusted through the rotating shaft ring 501. After adjusting to a suitable angle, the protective rod 5 is connected to another support rod 9, so that the device forms a temporary protection at the edge of the stairs. When the staff needs to disassemble the device, by unscrewing the fixing bolt 11, the support rod 9 can be pulled upward for disassembly, which is convenient for the staff to quickly disassemble the device after use. According to needs, the spring buckles 12 of multiple protective rods 5 can be snapped into the clamping blocks 2 of adjacent protective rods 5, so that multiple protective rods 5 can be spliced together for use, extending the protection length and range of the device.
