Two mounting columns 13 are fixedly installed on the top of the mounting plate 10, and the inner surfaces of the two movable columns 12 and the mounting columns 13 are fixedly installed with mounting blocks 14, and the inner surfaces of the two movable columns 12 and the mounting columns 13 are movably embedded with sliders 15. A second guardrail 16 is movably sleeved between the outer surfaces of every two of the four mounting blocks 14 and the sliders 15, and the inner surfaces of two of the four sliders 15 are movably inserted with threaded rods 17, and the outer surfaces of the two threaded rods 17 are fixedly sleeved with first gears 18, and one side of the outer walls of the two mounting columns 13 is fixedly installed with a motor 19, and the output ends of the two motors 19 are fixedly sleeved with second gears 20, and the outer surface wall of the second gear 20 is meshed and connected with the outer surface wall of the first gear 18.

[0024] The effect achieved by the entire embodiment 1 is that before the guardrail is moved and transported, it needs to be stored. First, under the action of the telescopic rod 6, the fixed plate 5 is driven to move to one side, thereby driving the first movable block 4 to move to one side inside the movable groove 3. At the same time, under the mutual cooperation of the first fixed block 2, the second fixed block 8 and the second movable block 9, the first guardrail 7 can be stored and the height of the second guardrail 16 can be lowered. Then, under the action of the motor 19, the second gear 20 is driven to rotate. At the same time, under the action of the first gear 18, the threaded rod 17 is driven to rotate, thereby driving the slider 15 to move downward inside the mounting column 13 and the movable column 12. At the same time, the movable column 12 will also move to one side inside the slide groove 11 to complete the storage of the second guardrail 16, and then complete the storage of the guardrail, reduce the volume of the guardrail, and make it easier to carry or move.

[0025] Embodiment 2, as Figure 2-Figure 4As shown, the outer wall of the base 1 is provided with four mounting grooves 21, the inner walls of the four mounting grooves 21 are provided with compression springs 22, one side of the outer wall of the four compression springs 22 is movably connected with a roller 23, and four fixed feet 24 are fixedly installed at the bottom of the base 1.

[0026] The effect achieved by the entire embodiment 2 is that after the guardrail is stored, firstly, under the action of the roller 23, the guardrail can be moved and carried more easily. When the guardrail is moved to a suitable position, under the operation of the staff, the pedal fixedly installed on the outer wall of the roller 23 is adjusted to a suitable angle. Then, under the action of the compression spring 22, the roller 23 can be stored, and the angle of the pedal can be adjusted again, so that the roller 23 is fixed and limited inside the installation groove 21, and then under the action of the fixed foot 24, it is fully fixed to the ground, thereby improving the stability of the guardrail during use and avoiding tipping.

[0027] Working principle: When in use, before moving the guardrail, its height and volume need to be adjusted. First, under the action of the telescopic rod 6, the fixed plate 5 is driven to move to one side, thereby driving the first movable block 4 to move to one side inside the movable groove 3. At the same time, under the cooperation of the first fixed block 2, the second fixed block 8 and the second movable block 9, the first guardrail 7 can be stored, and the height of the second guardrail 16 can be lowered. Then, under the action of the motor 19, the second gear 20 is driven to rotate. At the same time, under the action of the first gear 18, the threaded rod 17 is driven to rotate, thereby driving the slider 15 to move downward inside the mounting column 13 and the movable column 12. At the same time, the movable column 12 will also move to one side inside the slide groove 11 to complete the storage of the second guardrail 16, thereby completing the storage of the guardrail and reducing the volume of the guardrail. Subsequently, under the operation of the staff, the roller 23 is adjusted. The angle of the pedal installed on the outer wall is fixed and pressed, thereby driving the roller 23 to move downward inside the installation groove 21, so that the roller 23 contacts the ground. Under the action of the roller 23, the guardrail can be moved and carried more easily. When the guardrail is moved to a suitable position, the pedal is adjusted to a suitable angle again. Under the action of the compression spring 22, the roller 23 can be stored, and the roller 23 can be stored and fixed in position through the characteristic shape of the pedal and the installation groove 21. Then, under the action of the fixed foot 24, it is inserted into the ground, and the bottom of the base 1 is fully in contact with the ground, so that the guardrail is more stable when in use. Finally, the guardrail can be unfolded and put into use through the above structure, and when used at night, it can further play a warning and protection role through the action of multiple reflective stickers set on the outer wall of the guardrail.
