When the pull block moves inward, the bottom pressure spring contracts. When it reaches the sliding groove, the sliding block pops out due to the elastic force of the pressure spring, which clamps the pull block and limits the positioning block, so that the positioning block is stuck in the positioning groove. When the height needs to be changed, because the sliding block is pulled outward with an arc surface, it will be separated from the sliding groove by applying pressure outward, thereby releasing the limit on the extension column and adjusting the height. In this way, the requirements for the height of building guardrails in different situations can be met without frequently replacing building guardrails. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment: the bottom cross bar 61 is fixed by the plate groove 65, the top cross bar 61 is fixed by the limit groove 63, and then the required number of retractable cross bars 61 are inserted from the right side through the slide groove 68. The more the demand is, the smaller the spacing requirement is, and the more cross bars 61 are inserted. There is movable space at the top of the slide groove 68. By lifting the inserted vertical rod 66, the sliding block 69 at the bottom of the vertical rod 66 is disengaged from the sliding slot 610. After adjusting it to the appropriate spacing, the vertical rod 66 is lowered so that the sliding block 69 is stuck in the sliding slot 610 for fixing, thereby completing the adjustment of the spacing of the vertical rods 66.

[0031] Specifically, such as Figure 1 、 Figure 4 As shown, a positioning groove 51 is provided on the right side of the left extension column 3 and the left side of the right extension column 3 , and a positioning block 52 is movably connected to the inner side of the positioning groove 51 .

[0034] In this embodiment: the height of the entire pillar is raised by stretching the extension column 3, wherein a positioning groove 51 is provided in the extension column 3. When the required height is reached, the pressure pull rod 53 is pushed by pushing the pull block 54, so that the limit block 62 enters the inner side of the limit groove 63. When the pull block 54 moves inward, the bottom pressure spring 57 contracts. When it reaches the sliding groove 59, the sliding block 58 pops out due to the elastic force of the pressure spring 57, so that the pull block 54 is clamped and limited, so that the positioning block 52 is stuck in the positioning groove 51. When the height needs to be changed, because the sliding block 58 is pulled outward with an arc surface, it will be separated from the sliding groove 59 by applying pressure outward, thereby releasing the limit on the extension column 3 and adjusting the height. In this way, the requirements for the height of the building guardrail can be met in different situations without the need to frequently replace the building guardrail.

[0035] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 As shown, the bottom of the support base 2 is movably connected to a mounting plate 7.

[0037] In this embodiment: by setting up a mounting plate 7 to install the support base 2, the cumbersome problem of the traditional need to bolt each support base 2 can be avoided. By installing several support bases 2 on the mounting plate 7 and directly bolting the mounting plate 7, disassembly and assembly are more convenient.

[0038] Specifically, such as Figure 2 As shown, the right side of the left pull block 54 and the left side of the right pull block 54 are both fixedly connected with a pull ring 10.

[0040] In this embodiment, the pull ring 10 can be provided to conveniently drive the pull block 54 , and the buffer pad 11 can be provided to prevent personnel from accidentally colliding with the guardrail and causing personal injury.

[0041] Working principle: After the left bottom column 1 and the top column 4 are installed on the mounting plate 7, the height of the entire column is raised by stretching the extension column 3, wherein a positioning groove 51 is provided in the extension column 3. When the required height is reached, the pull block 54 is pushed to make the pressure pull rod 53 so that the limit block 62 enters the inner side of the limit groove 63. When the pull block 54 moves inward, the bottom pressure spring 57 contracts. When it reaches the sliding groove 59, the sliding block 58 pops out due to the elastic force of the pressure spring 57, so that the pull block 54 is stuck and limited, so that the positioning block 52 is stuck in the positioning groove 51. When the height needs to be changed, because the sliding block 58 is pulled outward with an arc surface, it will be separated from the sliding groove 59 by applying pressure outward, thereby releasing the limit on the extension column 3 and adjusting the height. After the height is adjusted, the bottom cross bar 61 is fixed by the plate groove 65, and the limit is set by The slot 63 fixes the top cross bar 61, and then the required number of retractable cross bars 61 are inserted from the right side through the slide 68. The more the demand is and the smaller the spacing requirement is, the more cross bars 61 are inserted. There is room for movement at the top of the slide 68, and by lifting the inserted vertical rod 66, the sliding block 69 at the bottom of the vertical rod 66 is disengaged from the sliding slot 610. After adjusting it to the appropriate spacing, the vertical rod 66 is lowered so that the sliding block 69 is snapped into the sliding slot 610 for fixing, thereby completing the adjustment of the spacing of the vertical rods 66, so that larger objects can be protected and smaller objects can be blocked. In this way, the spacing of the vertical rods 66 of the building guardrail can be adjusted more conveniently without frequently replacing the vertical rods 66 and cross bars 61. Finally, the bottom column 1 on the right side is installed and fixed to the bottom column 1 to complete the installation of the guardrail.
