That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is an easily adjustable angle follow spot light stand for stage, comprising a follow spot 1 and a center ring 2, the lower end of the center ring 2 is bent outward to form a supporting portion 3 of an annular structure, the supporting portion 3 is provided with an annular groove, and an adjusting ring 4 for adjusting the angle of the follow spot 1 is arranged in the annular groove, a U-shaped plate 5 is sleeved on the outside of the center ring 2, a universal pan-tilt head 11 is installed on the outer surface of the U-shaped plate 5, an L-shaped rod 7 is installed on the movable ball on the universal pan-tilt head 11, the other end of the L-shaped rod 7 is fixedly connected to the follow spot 1, a sealed bearing is installed on a transverse section of the L-shaped rod 7, a roller 8 is installed on the outside of the sealed bearing, and the outer ring surface of the roller 8 is in contact with the adjusting ring 4.
[0022] In this embodiment, a screw hole and a plurality of positioning holes are provided on the bottom surface of the support portion 3, a ball bearing is embeddedly installed on the bottom surface of the adjusting ring 4 opposite to the screw hole, a screw rod 14 is threadedly connected in the screw hole, one end of the screw rod 14 is installed in the inner ring of the ball bearing, and a hand wheel 13 is installed at the other end, a positioning rod 15 is provided in the positioning hole, and one end of the positioning rod 15 is installed on the bottom surface of the adjusting ring 4.
[0023] In this embodiment, multiple positioning plates 12 are installed on the outer side of the U-shaped plate 5, one end of the positioning plate 12 is bent and installed on the top surface of the U-shaped plate 5, the cross-section of the L-shaped rod 7 is arranged in a rectangular structure, and the two sides of the L-shaped rod 7 are in contact with the inner side surface of the positioning plate 12, so that the L-shaped rod can only move up and down along the inner side surface of the positioning plate.
[0024] In this embodiment, a handle 9 is installed at one end of the follow spot light 1, and the handle facilitates pushing the follow spot light.
[0025] In this embodiment, a positioning groove of an annular structure is provided on the outer ring surface of the center ring 2, and a positioning ring 6 is movably installed in the positioning groove. The outer ring of the positioning ring 6 is fixedly connected to the U-shaped plate 5. The U-shaped plate can be positioned through the positioning ring and the positioning groove so that the U-shaped plate can only rotate 360° along the positioning groove.
[0026] In this embodiment, a plurality of fixing seats 10 are installed on the bottom surface of the supporting portion 3, and support columns or telescopic rods can be installed on the fixing seats, so that the supporting portion can be supported and arranged.
[0027] In this embodiment, the U-shaped plate 5 is arranged in an arc-shaped structure, and the inner side surface of the U-shaped plate 5 contacts the inner ring and the outer ring of the center plate, increasing the contact area between the U-shaped plate and the center ring, so that the U-shaped plate can rotate smoothly along the center ring.
[0028] When in use, workers can stand in the center ring and isolate the outside through the center ring, which can better distinguish the working position;

[0030] After the actor's position changes, the hand wheel can be rotated, and the rotation of the hand wheel drives the screw rod to move upward along the screw hole. The movement of the screw rod drives the adjustment ring, which makes the adjustment ring rise steadily along the positioning rod. After the adjustment ring moves, the illumination angle of the follow-spot light can be lifted upward, so that the follow-spot light is lifted upward with the universal head as the center, and the L-shaped rod can only move up and down along the inner side of the positioning plate, avoiding the rotation of the L-shaped plate, so that the follow-spot light can still follow in a stable posture after the angle is changed.
[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
