Parts of the balls 17 penetrate the placement grooves 18 and are closely connected to the outer side of the first pillar 1. When the sleeve 3 moves, it can drive the placement grooves 18 to roll along the outer side of the first pillar 1, thereby reducing the resistance between the sleeve 3 and the first pillar 1.

[0029] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 The upper end of the outer side of the second pillar 13 is fixedly sleeved with a fixing seat 12, the bottom of the sleeve 3 is fixedly connected with a positioning block 10, and the top of the fixing seat 12 is provided with a positioning groove 11 that is plugged with the positioning block 10.

[0030] Please refer to the attached figure in the instruction manual Figure 1, grooves 4 are provided on both sides of the first pillar 1, and connecting plates 8 are fixedly installed at the lower ends of the two groups of grooves 4. Screws 7 are rotatably connected between the tops of the two groups of connecting plates 8 and the inner top walls of the grooves 4 through bearings, and servo motors 9 for driving the screws 7 to rotate are installed at the bottoms of the two groups of connecting plates 8. A reserved groove 16 is provided on the right side of the sleeve 3, and a control switch 15 is installed inside the reserved groove 16. A cover plate 14 is clamped on the outside of the reserved groove 16, and the output end of the control switch 15 is electrically connected to the input end of the servo motor 9.

[0032] Working principle: When in use, the anti-corrosion coating is applied to the welding joint at the bottom of the first pillar 1 and the top of the second pillar 13 and slowly becomes a solidified state, and then the servo motor 9 is started to rotate by the control switch 15, and the servo motor 9 rotates to drive the nut 5 to move downward, and the nut 5 moves downward to drive the limit block 19 to slide in the limit groove 20, so that the nut 5 can be limited, and the sleeve 3 is driven to move downward through the connecting block 6 when the nut 5 moves downward, and the sleeve 3 drives the positioning block 10 to move downward until the positioning block 10 is inserted into the positioning groove 11. At this time, the sleeve 3 is in contact with the fixing seat 12, so that the welding joint can be covered and protected by the sleeve 3, so that the anti-corrosion coating will not be exposed to the air, and the anti-corrosion coating after solidification is avoided as much as possible from being eroded by rainwater and falling off. At the same time, the sleeve 3 can drive the ball 17 to roll along the outer side of the first pillar 1 while moving, which can reduce the resistance of the sleeve 3 when moving. The setting of the rubber ring 2 can improve the sealing between the sleeve 3 and the first pillar 1, effectively prevent rainwater from penetrating into the interior, and improve the service life of the steel structure pillar.
