[0034] A plurality of inclined-stayed components 5, wherein the plurality of inclined-stayed components 5 are all arranged outside the square tube 7, and the plurality of inclined-stayed components 5 are distributed in an equidistant annular pattern with the central axis of the square tube 7 as the center;

[0035] The inclined-stayed assembly 5 includes a hanging ring 3, a hook 4, a steel rope 2 and a traction mechanism 1. The extension column 6 is coaxially fixed with the hanging ring 3. One end of the steel rope 2 is fixed with the hook 4. The steel rope 2 is buckled on the hanging ring 3 through the hook 4. The traction mechanism 1 applies traction to the other end of the steel rope 2.

[0036] From the above connection relationship, it can be known that the traction mechanism 1 in each inclined-stayed assembly 5 applies traction force to the steel rope 2, and the steel rope 2 guides the traction force to the top of the extension column 6. When there is a bending tendency on one side of the support mechanism 8 composed of the square tube 7 and the extension column 6, the steel rope 2 on the opposite side of the support mechanism 8 with the bending tendency will apply corresponding tension to offset it, thereby improving the bending resistance of the support mechanism 8.

[0037] like Figure 3 and 4 As shown, in one embodiment, the driving mechanism 15 includes a fixed plate 11, a transmission structure, a rotating rod 14 and a threaded column 10. The fixed plate 11 is fixed in the square tube 7. The plate surface of the fixed plate 11 is provided with a first rotating hole. One end of the threaded column 10 is rotatably installed in the first rotating hole. The end of the extension column 6 located in the square tube 7 is provided with a threaded hole. The outer side of the threaded column 10 is installed in the threaded hole through a thread. The opposite side of the square tube 7 is provided with a second rotating hole. The two ends of the rotating rod 14 are rotatably installed in the two second rotating holes respectively.

[0038] like Figure 4 As shown, in one embodiment, a ring handle coaxially arranged therewith is fixed at one end of the rotating rod 14. When a worker rotates the ring handle, the ring handle drives the rotating rod 14 to rotate. The outer side of the ring handle is wrapped with a rubber layer for increasing friction.

[0039] like Figure 2 As shown, in one embodiment, the hook 4 is a lockable hook 4 , the hook 4 is hung on the hanging ring 3 of the extension column 6 , and then the hook 4 is locked, which can prevent the hook 4 from being separated from the hanging ring 3 .

[0040] like Figure 5 and Figure 6As shown, in one embodiment, the traction mechanism 1 includes a base plate 16, a large diameter gear 20, a small diameter gear 22, a first rotating shaft 23, a second rotating shaft 24, a groove wheel 21 and a resistance structure. Two support plates 25 are fixed on the top of the base plate 16. The second rotating hole and the third rotating hole are opened on the opposite sides of the two support plates 25. The two ends of the first rotating shaft 23 are respectively rotatably installed in the second rotating hole, and the two ends of the second rotating shaft 24 are respectively rotatably installed in the two third rotating holes. The groove wheel 21 is coaxially fixed with the first rotating shaft 23, one end of the steel rope 2 is fixed in the groove of the groove wheel 21, the first rotating shaft 23 is coaxially fixed with the small diameter gear 22, the second rotating shaft 24 is coaxially fixed with the large diameter gear 20, and the small diameter gear 22 is meshed with the large diameter gear 20. The resistance structure applies a reverse torque force to the large diameter gear 20. Since the diameter of the large diameter gear 20 is larger than the diameter of the small diameter gear 22, it is difficult for the small diameter gear 22 to shift the large diameter gear 20; the resistance structure includes The invention comprises a damping rod 18, a spring 17 and two positioning rings 19. The two ends of the damping rod 18 are respectively rotatably mounted on the plate surface of the bottom plate 16 and the edge of the circular surface of the large-diameter gear 20. The two ends of the damping rod 18 are respectively coaxially fixed with the two positioning rings 19. The two ends of the spring 17 are respectively fixed with the positioning rings 19, and the spring 17 is sleeved on the damping rod 18. The hanging ring 3 pulls the steel rope 2 out of the groove wheel 21 through the hook 4. The steel rope 2 drives the groove wheel 21 to rotate. The groove wheel 21 passes through the first A rotating shaft 23 drives the small diameter gear 22 to rotate, and the small diameter gear 22 shifts the large diameter gear 20 meshing with it. The large diameter gear 20 stretches the damping rod 18, and at the same time, the spring 17 on the damping rod 18 is stretched, applying a reverse torque to the large diameter gear 20, so that the steel rope 2 is always kept taut. At the same time, the more the extension column 6 is extended, the greater the traction force of the steel rope 2 will be, so as to ensure that the support mechanism 8 composed of the extension column 6 and the square tube 7 has sufficient bending resistance when it is at a higher height.

[0041] The specific working methods are:

[0042] In the first step, the square tube 7 is placed on the ground, and the bottom end of the square tube 7 is fixed to the ground by fixing bolts;

[0043] The second step is to place the bottom plate 16 flat on the ground, determine the distance between the bottom plate 16 and the square tube 7, and then fix the bottom plate 16 on the ground with fixing bolts;

[0044] The third step is to hang the hook 4 on the steel rope 2 on the hanging ring 3 of the extension column 6. Since the hook 4 is a lockable type, the hook 4 is hung on the hanging ring 3 of the extension column 6, and then the hook 4 is locked;

[0045] The fourth step is to place the crossbeam of the template on the bracket 9;

[0046] In the fifth step, the worker rotates the ring handle, which drives the rotating rod 14 to rotate. The second bevel gear 13 on the rotating rod 14 rotates synchronously with the rotating rod 14. The second bevel gear 13 drives the threaded column 10 to rotate through the first bevel gear 12 meshing therewith. The outer side of the threaded column 10 pushes the extension column 6 out of the square tube 7 through the form of thread transmission. The hanging ring 3 on the extension column 6 moves synchronously with the extension column 6. The hanging ring 3 pulls the steel rope 2 out of the groove wheel 21 through the hook 4. The steel rope 2 drives the groove wheel 21 to rotate. The groove wheel 21 drives the small diameter gear 22 to rotate through the first rotating shaft 23. The small-diameter gear 22 moves the large-diameter gear 20 meshing with it, and the large-diameter gear 20 stretches the damping rod 18. At the same time, the spring 17 on the damping rod 18 is stretched, exerting a reverse torque on the large-diameter gear 20, so that the steel rope 2 is always kept taut. At the same time, the more the extension column 6 is extended, the greater the traction force of the steel rope 2 will be, so as to ensure that the support mechanism 8 composed of the extension column 6 and the square tube 7 has sufficient anti-bending ability at a higher height. If the support mechanism 8 shakes, the damping rod 18 and the spring 17 can play a buffering effect to reduce the shaking amplitude of the support mechanism 8.
