[0009] Optionally, slots are provided at the four corners of the base sidewall, and a second bolt extending to the bottom of the base is inserted into each slot.

[0010] The beneficial effects of this utility model are:

[0011] 1. When assembling the guardrail, first unscrew the third bolt and flip the cover plate. Then, move the first and second posts in sequence from the slot on the base to make the first and second posts vertical. Then, take the four crossbars out of the storage slot and install them between the first and second posts. The whole installation process is simple and convenient. After installation, the base can provide stable support at the bottom of the guardrail, making the guardrail less likely to tip over.

[0012] 2. When carrying and transporting this device, firstly, the four crossbars need to be removed from between the first and second columns. Then, place the crossbars in pairs at the bottom of the storage slot. Next, rotate the second column to flip it into the storage slot and press it on top of the crossbars. Then, flip the first column to flip it into the storage slot and press it on top of the second column. Finally, close the cover plate in the slot and use the third bolt to connect it with the third threaded groove to fix the position of the cover plate. Attached Figure Description
