[0078] In other embodiments, if the height of the positioning rod 13 on the second adjusting rod 9 is not adjusted, the positioning rod 13 and the second adjusting rod 9 can be fixedly connected.

[0079] The side of the fixed sleeve 14 is also provided with an operating rod fixing assembly for fixing the operating rod when it is rotated to the highest point;

[0080] The first support rod 1 and the first adjusting rod 2 are further provided with a compression spring 26, and the bottom of the compression spring 26 can be supported by a positioning bolt 25, and the positioning bolt 25 is in sliding connection with the first adjusting rod 2, so that when the first support rod 1 is extruded to slide outside the first adjusting rod 2, the compression spring 26 is extruded by the positioning bolt 25, and the height of the slide of the lateral arm assembly 5 outside the first support rod 1 is limited by the positioning bolt 25, so that when the operating rod of the extrusion rod 16 is rotated to the highest point at 90 degrees, the compression spring 26 is driven to be compressed under the displacement of the meshing of the driving gear 17 and the rack of the positioning rod 13, the matching of the height between the length adjusting assembly and the two fixed points is realized, and the pressure between the support part 3 and the fixed point is increased.

[0081] In the embodiment, the elasticity of the compression spring 26 can be adjusted according to the actual application, and the elasticity needs to meet the condition that the top support part 3 can be supported by the rigidity of the compression spring 26 without large external force, and the compression spring 26 will not be compressed due to the weight of the top support part 3.

[0082] The operating rod fixing assembly comprises a rectangular clamping plate 18 fixed on one side of the operating rod and a limiting plate 20 rotatably connected to one side of the fixed sleeve 14.

[0083] In the embodiment, a torsion spring is fixed between the limiting plate 20 and the fixed sleeve 14, so that the limiting plate 20 rotates downward after being subjected to external force, and the limiting plate 20 rotates upward to reset by the rebound of the torsion spring after the external force disappears. An anti-reverse plate 21 is fixed to one end of the limiting plate 20 close to the first support rod 1, so that the limiting plate 20 can only rotate downward and cannot rotate upward by the limitation of the anti-reverse plate 21.

[0084] In the embodiment, a limiting inclined surface 24 is formed in the inner side of the fixed sleeve 14 and at the bottom of the limiting plate 20, so as to limit the stroke of the downward rotation of the limiting plate 20 by the limiting inclined surface 24.

[0085] A second extrusion inclined surface 22 is arranged on the side of the limiting plate 20 close to the operating rod, so that the rectangular clamping plate 18 drives the limiting plate 20 to rotate by extruding the second extrusion inclined surface 22, and a limiting groove 23 is arranged between the second extrusion inclined surface 22 and the rotation shaft of the limiting plate 20, so that the rectangular clamping plate 18 enters the inner side of the limiting groove 23 after extruding the limiting plate 20; for ensuring that the limiting plate 20 can rotate to reset and clamp the rectangular clamping plate 18 after the rectangular clamping plate 18 extrudes the second extrusion inclined surface 22 and enters the limiting groove 23.

[0086] In the embodiment, a torsion spring is assembled between the limiting plate 20 and the fixing sleeve 14, so that the rotation of the extruding rod 16 inside the fixing sleeve 14 makes the rectangular clamping plate 18 extrude the limiting plate 20, and the limiting plate 20 rotates downward and drives the torsion spring to store energy. The upward rotation of the limiting plate 20 resets the rectangular clamping plate 18 to the inside of the limiting slot 23, and the extruding rod 16 cannot be directly pulled in the direction away from the first supporting rod 1.

[0087] The winch 7 is fixed on one side of the assembly plate 10, and the position of the winch 7 is fixed through the assembly plate 10. The assembly plate 10 is fixed on one side of the first adjusting part 6, so that the first adjusting part 6 drives the assembly plate 10 to synchronously ascend and descend and rotate. The first adjusting part 6 is assembled above the fixing sleeve 14, and the bottom end of the first adjusting part 6 is supported through the fixing sleeve 14.

[0088] In the embodiment, the first adjusting part 6 is slidably connected to the outside of the first supporting rod 1 and the bottom of the supporting clamp 4, so that the first adjusting part 6 can ascend and descend and rotate on the outside of the first supporting rod 1.

[0089] The horizontal arm assembly 5 includes a rotating frame 33 and a horizontal rod assembled on one side of the rotating frame 33, so that the horizontal rod can be adjusted in rotation on one side of the rotating frame 33.

[0090] The horizontal rod includes at least one connecting cylinder. When there are multiple connecting cylinders, each connecting cylinder is sleeved and slidably connected and fixed through a bolt.

[0091] The inner side of the rotating frame 33 is rotationally connected with the first support rod 1, so that the rotating frame 33 can only slide up and down on the outer side of the first support rod 1, and the rotating frame 33 can also rotate in the plane of the outer side of the first support rod 1.

The shape of the first connecting barrel 35 on the inner side of one end of the rotating frame 33 is adjusted through the two adjusting bolts 34. The connecting position of the first connecting barrel 35 and the rotating frame 33 can be limited by the adjusting bolt 34 close to one end of the first support rod 1. At this time, the adjusting bolt 34 away from one end of the first support rod 1 is separated from the rotating frame 33, so that the first connecting barrel 35 can rotate on the inner side of the rotating frame 33. The storage folding after the rotation of the first connecting barrel 35 is completed or the work is unfolded. After rotation, the adjusting bolt 34 away from one end of the first support rod 1 enters the inside of the rotating frame 33, so that the limiting position after storage folding can be limited to prevent upward rotation after folding. The fixed work after unfolding can also be realized. At this time, the axis of the first connecting barrel 35 is perpendicular to the axis of the first support rod 1. The inner side of one end of the first connecting barrel 35 is slidably connected with the second connecting barrel 36. When the length of the second connecting barrel 36 in the first connecting barrel 35 is not required to be adjusted, the first connecting barrel 35 and the second connecting barrel 36 can be positioned by the two adjusting bolts 34.

[0093] In the embodiment, the first connecting barrel 35 is rotationally connected with the first roller 38 close to the top of one end of the first support rod 1. The second connecting barrel 36 is fixed with a support frame 37 on both sides away from one end of the first support rod 1. The second roller 39 is rotationally connected between the two support frames 37. Thus, one end of the steel wire rope on the winch 7 can enter the outside of the first roller 38 from the inner side of the rotating frame 33, and then enter the outside of the second roller 39 and extend downward. One end of the steel wire rope is fixed by a hook. Thus, the work of the winch 7 can make the steel wire rope slide and stretch through the cooperation of the first roller 38 and the second roller 39. The anti-loose bolt 40 is threadedly connected to the top of one end of the first support rod 1 away from the first support rod 1. Thus, the steel wire rope located between the two support frames 37 and outside the second roller 39 is limited by the anti-loose bolt 40 to prevent the steel wire rope from loosening and separating from the two support frames 37.

[0094] The cross bar is rotationally connected with the rotating frame 33,
