[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] See also Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution: the spatial curved surface structure template supports the top component, including a vertical pole 1, the top of the vertical pole 1 is fixed with a mounting ring 2 by bolts, the mounting ring 2 is located at the bottom of the support platform 3, and positioning plates 4 are fixed on both sides of the support platform 3 by bolts. A rotating shaft screw column 5 is installed in the center of the positioning plate 4, and the rotating shaft screw column 5 passes through a rotating block 6, and the rotating block 6 is located at the bottom of the support plate 8. A joist 9 is installed on the upper surface of the support plate 8, and a limiting mechanism is set on both sides of the joist 9. When the joist 9 is placed on the surface of the support plate 8, the joist 9 is fixed by the limiting mechanism to prevent the joist 9 from slipping when the support plate 8 is tilted;

[0025] Furthermore, the contact surfaces of the positioning plate 4 and the rotating block 6 are respectively provided with annular teeth 7, which are engaged with each other. The cross section of the annular teeth 7 is a right triangle. When the rotating block 6 is turned, the annular teeth 7 on the surface of the positioning plate 4 are fixed, and the annular teeth 7 on the surface of the rotating block 6 slide along the inclined surface. After the angle is correct, tighten the shaft screw column 5 to ensure that the angle remains unchanged.

[0026] See also Figure 1 、 Figure 2 and Figure 3 As shown, the limiting mechanism includes a limiting plate 10, a cam 13, a damping shaft 14 and a handle 15. The limiting plates 10 are arranged on both sides of the joist 9. The cams 13 are installed on the outer side of the limiting plate 10. The cam 13 is rotatably connected to the support plate 8 through the damping shaft 14. A handle 15 is fixed on the surface of the cam 13. The handle 15 has two working states. The first is that the handle 15 is perpendicular to the support plate 8, and the second is that the handle 15 is parallel to the support plate 8. When the handle 15 rotates from the first state to the second state, the cam 13 squeezes the limiting plate 10, so that the limiting plate 10 moves toward the joist 9 at the same time, clamping the joist 9 to prevent the joist 9 from sliding.

[0027] Furthermore, a protrusion is provided at the bottom of the limit plate 10, and the protrusion is located in the movable groove 11 on the surface of the support plate 8. A telescopic rod 12 is symmetrically installed on the inner surface of the protrusion, and the telescopic rod 12 is inserted into the inner wall of the movable groove 11. The moving direction of the limit plate 10 is determined by the telescopic rod 12, and at the same time, the limit plate 10 is prevented from leaving the movable groove 11.

[0028] Furthermore, V-shaped grooves 16 are provided on both sides of the support plate 8 , and the V-shaped grooves 16 make it convenient to hold the handle 15 by hand.

[0029] Furthermore, a limiting tooth 17 is installed on the top of the limiting plate 10. The limiting tooth 17 is designed in an arc shape and is rotatably connected to the limiting plate 10 through a damping shaft, so that the limiting tooth 17 is away from one end of the limiting plate 10 and buckled on the surface of the joist 9;

[0030] It should be noted that when the limiting teeth 17 are fastened to the joist 9 , the limiting teeth 17 are always lower than the highest point of the joist 9 .

[0031] Furthermore, a groove 18 is formed on the outer surface of the protrusion. When the handle 15 is rotated from the first state to the second state, the protruding end of the cam 13 can be embedded in the groove 18 to prevent the cam 13 from rotating accidentally.

[0032] Working principle:

[0033] Put the mounting ring 2 on the top of the vertical pole 1 of the support system, and then tighten the bolts until the bolts touch the surface of the vertical pole 1;

[0034] Pull the support plate 8 upwards so that the annular teeth 7 on the surface of the rotating block 6 rotate upward along the inclined surface of the annular teeth 7 on the surface of the positioning plate 4. When the tilt angle is correct, tighten the shaft screw column 5 to fix the angle;

[0035] Place the joist 9 on the surface of the support plate 8, then pull the handle 15 and rotate it from perpendicular to the support plate 8 to parallel to the support plate 8. During the process, the cam 13 squeezes the limit plate 10, and the limit plate 10 moves along the moving groove 11 toward the joist 9. At the same time, the telescopic rod 12 is compressed and retracted into the inside of the moving groove 11 until the limit plate 10 fits the joist 9. At this time, the protruding end of the cam 13 is embedded in the inside of the groove 18, and then, the limit teeth 17 are fastened inward to prevent the joist 9 from slipping.
