In order to adjust the lighting effect and angle of the stage lamp 13, the flexibility is improved. In rainy, snowy and hail weather, in order to avoid damage to the stage lamp 13 by rain or hail outdoors, the driving motor 6 is a servo motor, and the output end can rotate forward and reverse. When the driving motor 6 is working, it will drive the winding rod 7 to move synchronously, and then drive the winding wheel 8 to rotate. When the winding wheel 8 rotates, the steel cable 9 can be retracted and released, and then the strip plate 12 can be driven to move through the steel cable 9, so that the position of the stage lamp 13 can be adjusted. When the driving motor 6 works, it will reel the steel cable 9, and then the strip plate 12 will move. When the strip plate 12 moves, it will drive the stage lamp 13 to move synchronously. The movement of the strip plate 12 will drive the stage lamp 13 to move into the storage slot 14, so as to achieve The purpose of storing the stage light 13 is to prevent the stage light 13 from being damaged by bad weather such as rain, snow or hail. When the strip plate 12 enters the storage groove 14 and continues to move upward, it will exert pressure on one end of the driving plate 18, and the driving plate 18 will make a circular motion around the support shaft 17. When the other end of the driving plate 18 moves downward, the sealing plate 21 will move through the connection shaft 19, the connection groove 27, the connection plate 26 and the connection frame 25. The sealing plate 21 moves and enters the storage groove 14 to seal the bottom of the storage groove 14, thereby improving the sealing of the storage groove 14, further improving the protection of the stage light 13, and effectively preventing the external rain or hail from contacting the stage light 13 and causing damage to the stage light 13. The sealing plate 21 moves When the sealing plate 21 moves inside the storage slot 14, the rubber block 32 will squeeze the air inside the cylinder 30, and the squeezed air will enter the flow slot 33 through the connector 31, and the wind will flow to the storage slot 14 through the jet head 34. After the wind flows through the surface of the stage light 13, the residual rainwater adsorbed on the stage light 13 can be removed, thereby improving the drying efficiency, effectively preventing rainwater from being adsorbed on the stage light 13 and causing damage to the stage light 13, and improving the protection of the stage light 13. After the rain and snow, the output end of the driving motor 6 moves in the opposite direction, which will cause the strip plate 12 to move downward.When the strip plate 12 moves downward, the driving assembly is no longer pressed, and the return spring 39 is reset to pull the sealing plate 21 to reset, thereby no longer sealing the bottom of the storage slot 14, and the strip plate 12 can drive the stage light 13 to move to the outside.
