[0023] When the full-supports 1 are erected at a certain angle, the support in the bent fan-shaped area is erected separately to meet the small-radius angle requirement of the full-supports 1.

[0024] Further, the fan-shaped supports 2 are long rods arranged in multiple rows, one end of the long rods of the fan-shaped supports 2 is connected to the same rod body, the rod bodies connected by the long rods of the two fan-shaped supports 2 are hingedly connected together through the deflection column 202, the connecting rod 201 comprises an embedded groove 2011, a matched convex ring 2012 and a ball 2013, the embedded groove 2011 is arranged at one end of the connecting rod 201, the matched convex ring 2012 is arranged at the opening of the embedded groove 2011, and the ball 2013 is connected to the inner wall of the matched convex ring 2012.

[0025] When the fan-shaped area of the full-supports 1 is erected, the fan-shaped supports 2 connected together through the deflection column 202 are placed on one side of the full-supports 1, then one side of the fan-shaped supports 2 is forced to expand along an arc to adjust to the required radius angle and form a frame, then the telescopic rod 203 is pulled out of the embedded groove 2011 at one end of the connecting rod 201 to cooperate with the expansion of the fan-shaped supports 2, and the telescopic rod 203 and the connecting rod 201 are connected in the displacement groove 204 and the limiting sliding groove 2041, so that the telescopic rod 203 and the connecting rod 201 can adjust the angle to adjust to the transverse direction, when the fan-shaped supports 2 are expanded to the appropriate angle, the limiting ring 2032 is rotated and moved along the screw thread of the telescopic rod 203 to move against one end of the connecting rod 201, so that the fan-shaped supports 2 cannot be inwards, and because the full-supports 1 are built on both sides of the fan-shaped supports 2, the fan-shaped supports 2 cannot be expanded outwards, so that the fan-shaped supports 2 can be kept stable to be erected in the fan-shaped area of the full-supports 1, and the angle of each rod body does not need to be adjusted in sequence, the flexible adjustment can be carried out multiple times, the support profile with uniform angle can be quickly erected, and the auxiliary support can be conveniently and quickly erected.

[0026] Further, the matching convex ring 2012 is a circular ring protrusion on the inner wall of the opening of the embedded groove 2011, and the ball 2013 is a ball connected to the inner wall of the matching convex ring 2012, the outer wall of the telescopic rod 203 is matched with the ball 2013, and one end of the connecting rod 201 is also connected to the displacement groove 204 and the limiting sliding groove 2041 through the hinge shaft 2031.

The inner wall of the limiting ring 2032 is threadedly matched with the outer wall of the telescopic rod 203, and the matching disc 2033 is matched with the embedded groove 2011.

[0027] Finally, the outer wall of the telescopic rod 203 is matched with the ball 2013, and the friction of the thread on the side wall of the telescopic rod 203 is reduced through the rolling of the ball 2013, so as to avoid the telescopic rod 203 from being stuck when being extended.

[0028] The specific process of the utility model is as follows. When the full-bay support 1 is erected at a certain angle, a support is erected separately in the bent fan-shaped area to meet the requirement of the small radius angle of the full-bay support 1. When the fan-shaped area of the full-bay support 1 is erected, the fan-shaped supports 2 connected by the deflection column 202 are placed on one side of the full-bay support 1, and then one side of the fan-shaped support 2 is forced to expand along the arc, so as to adjust to the required radius angle and form a frame. When the fan-shaped support 2 is expanded, the telescopic rod 203 is extended from the embedded groove 2011 at one end of the connecting rod 201, so as to cooperate with the expansion of the fan-shaped support 2. The telescopic rod 203 and the connecting rod 201 are connected in the displacement groove 204 and the limiting sliding groove 2041, so that the telescopic rod 203 and the connecting rod 201 can adjust the angle in cooperation with the expansion of the fan-shaped support 2, so that the fan-shaped support 2 can be adjusted to be horizontal. When the fan-shaped support 2 is expanded to the appropriate angle, the limiting ring 2032 is rotated and moved along the thread of the telescopic rod 203 to move against one end of the connecting rod 201, so that the fan-shaped support 2 will not shrink inward by itself. Since the full-bay support 1 is built on both sides of the fan-shaped support 2, it will not continue to expand outward, so that the fan-shaped support 2 can remain stable and be erected in the fan-shaped area of the full-bay support 1. It is not necessary to adjust the angle of each rod body in sequence during the erection of the fan-shaped area, and the fan-shaped support 2 can be adjusted flexibly for many times. In addition, the support profile with uniform angle can be erected more quickly, and it is more convenient and faster to erect the auxiliary support connected stably.
