One end of the column rod 12 in the cylinder 17 is connected and fixed with a piston 21, and the piston 21 is slidably installed in the cylinder 17. A disk 22 with an outer diameter smaller than that of the piston 21 is connected and fixed on two parallel sides of the piston 21. The disk 22 improves the stability of the structure of the piston 21. A U-shaped seat 15 is rotatably installed at the closed end of the cylinder 17, that is, the closed end of the cylinder 17 is connected and fixed with two symmetrically arranged shaft ears 16, and the two shaft ears 16 are rotated by a rotating shaft. An intermediate ear 14 is installed, and the intermediate ear 14 is connected and fixed with the U-shaped seat 15. A valve 13 communicating with the inner space of the cylinder 17 is installed on the outer surface of one end of the cylinder 17 near the U-shaped seat 15. The U-shaped seat 15 is rotatably connected with the corresponding carrier by a circular shaft, and then the connecting seat 1 is installed on the building component by bolts. At this time, the structure formed by the column rod 12 and the cylinder 17 and other components is in an inclined state, which plays a role of oblique pulling. After opening the valve 13, the relative position of the column rod 12 and the cylinder 17 is adjusted. At this time, air enters and exits the space formed by the cylinder 17 and the piston 21 through the valve 13, so as to adjust the length of the structure formed by the components such as the column rod 12 and the cylinder 17. After closing the valve 13, the air is not in the space formed by the cylinder 17 and the piston 21. At this time, the piston 21 keeps a relative position unchanged with the cylinder 17 under the action of the air pressure difference, because the air in the space formed by the piston 21 and the cylinder 17 can be compressed to a certain extent, so the piston 21 can produce a small range of movement in the cylinder 17 under the action of external force, so as to achieve the purpose of buffering.

[0024] Refer to Figures 1 - 3 , first nuts 4 are provided on both sides of the through hole 19 along the length direction of the stud 3. The first nuts 4 are threadedly connected to the stud 3. Two second fixing holes 9 are provided on the upper surface of the movable seat 8. According to the strength of the building component, the position of the stud 3 is adjusted along the through hole 19. At this time, the distance between the movable seat 8 and the connecting seat 1 changes, that is, the distance between the first fixing hole 2 and the second fixing hole 9 changes. Then, the relative position of the stud 3 and the connecting seat 1 is restricted by the first nut 4, completing the adjustment of the relative position of the movable seat 8 and the connecting seat 1. After the bolts passing through the first fixing hole 2 and the second fixing hole 9 are assembled with the building component, the connection range of the connection structure formed by the connecting seat 1 and the movable seat 8 and other components with the building component changes, which is beneficial to reducing the reaction force received per unit area of the building component at the position where the connecting seat 1 is installed and improving the stability of the overall structure.

A plugging hole 20 matched with the plugging rod 10 is provided on the surface of the connecting seat 1 facing the movable seat 8. The plugging rod 10 is inserted into the plugging hole 20 to realize the plugging of the movable seat 8 and the connecting seat 1.
