An auxiliary roller 32 is rotatably arranged on the sliding rod 33, and the outer surface of the auxiliary roller 32 is provided with anti-slip grooves, which is convenient for users to use the auxiliary roller 32 to make corresponding adjustments, so as to meet actual use requirements. There are two insert blocks 39 in total, and the two insert blocks 39 can be plugged into the connecting plate 31. A sliding groove for passing through the two ends of the connecting rod 38 is opened on the driving shaft 211, and both ends of the sliding groove are closed. The friction block 37 is a ring structure design, and the side of the friction block 37 is provided with friction grooves for enhancing friction.

[0032] Working principle: Ribs 16 are set inside the sphere 11, and anchor bolts 12 connected to the grid are welded on the sphere 11. At the same time, pouring holes 13 and air holes 14 are respectively opened on the sphere 11, so that steel fiber concrete can be poured into the sphere 11 to improve the strength of the entire node structure 1;When the height of the node structure 1 needs to be adjusted, the pull ring 311 is pulled, and the second ball head rod 312 fixedly connected to the sliding rod 33 slides inside the sliding rod 33, so that the ball head end of the second ball head rod 312 is separated from the ball head end of the third ball head rod 315. Because the end of the third ball head rod 315 is fixed with a plug block 39 that can be plugged into the connecting plate 31, the rod body of the third ball head rod 315 is fixed with a second convex plate 317, and the second convex plate 317 slidably connected to the sliding rod 33 is further connected to the sliding rod 33 using a third spring 316. Under the pulling force of the third spring 316, the plug block 39 can be pulled to slide toward the inside of the sliding rod 33, so that the plug block 39 is separated from the connecting plate 31. At this time, the sliding rod 33 can be pushed to slide on the connecting plate 31, so that the sliding rod 33 is in a The pull ring 311 is released at the lower end of the connecting plate 31, and the first convex plate 313 is also fixed on the rod body of the second ball head rod 312, and the first convex plate 313 is also further connected to the sliding rod 33 by the second spring 314. Under the action of the second spring 314, the second ball head rod 312 will slide in the opposite direction, and the ball head end of the second ball head rod 312 can squeeze the third ball head rod 315 to push the insert block 39 into the connecting plate 31. When the sliding rod 33 is at the lower end of the connecting plate 31, the spherical protrusion 34 on the side of the sliding rod 33 is staggered with the ball head end of the first ball head rod 35, and the end of the first ball head rod 35 slidably connected to the active shaft 211 is fixed with the connecting rod 38, and the end of the connecting rod 38 is also fixed with the friction block 37, and the connecting rod 38 and the active shaft 211 are also connected by the friction block 37. The first spring 36 is further connected. Therefore, when the first ball head rod 35 is staggered with the spherical protrusion 34, the friction block 37 is pulled to slide under the action of the first spring 36, so that a gap is generated between the friction block 37 and the fixed cylinder 22. At this time, after the connecting plate 31 is driven to rotate by the auxiliary roller 32 and the sliding rod 33, the driving shaft 211 fixedly connected to the connecting plate 31 rotates together inside the fixed cylinder 22. Because the main bevel gear 210 at the end of the driving shaft 211 is meshed and connected with the secondary bevel gear 29 at the end of the driven shaft 28, and the driven shaft 28 rotatably set on the mounting plate 27 is also fixedly connected to the screw rod 25, after the connecting plate 31 drives the driving shaft 211 to rotate, the main bevel gear 210, the secondary bevel gear 29 and the driven shaft 28 are meshed and connected. Under the drive of the shaft 28, the screw rod 25 rotates together inside the fixed cylinder 22, and the inner cavity of the movable cylinder 21 slidably connected to the fixed cylinder 22 is fixed with the auxiliary nut 26 threadedly connected to the screw rod 25. Therefore, after the screw rod 25 rotates, the movable cylinder 21 can slide on the fixed cylinder 22, and the end of the movable cylinder 21 is fixed with the support seat 15 welded to the ball 11. After the movable cylinder 21 slides, the position height of the node structure 1 can be adjusted, and the sliding rod 33 is pushed to slide again, and the spherical protrusion 34 of the sliding rod 33 is used to squeeze the first ball head rod 35 to eliminate the gap between the friction block 37 and the fixed cylinder 22, so that the friction pattern on the side of the friction block 37 is in close contact with the fixed cylinder 22, generating a certain friction force, locking the internal structure, and then locking the position of the node structure 1. ;
