Relying on the above arrangement, the fixed arm 21 is pressed down to fix the base 11, thereby improving the fixing effect and stability. During the process of pressing down and rotating the fixing plate 31, the fixing plate 31 is in contact with the ground, thereby increasing the contact area with the ground and improving the fixing effect, and the support spring 32 is used to play the role of the current fixing plate 31, thereby reducing the situation where the fixing plate 31 vertically droops and contacts after the fixed arm 21 is lifted.

[0026] Further, such as Figure 2 As shown, a rubber sleeve 51 is fixed to the bottom of the support 13, and the bottom of the rubber sleeve 51 is fixed to the base 11. The multiple piston viscous dampers 14 and shock-absorbing springs 15 are all located inside the rubber sleeve 51. Sliding sleeves 52 are fixed to both sides of the rubber sleeve 51. The screw 24 passes through the sliding sleeve 52 and is slidably connected thereto. A spring piece 53 is fixed between the base 11 and the support 13, and the spring piece 53 is fixed to the inner wall of the rubber sleeve 51. When in use, the rubber sleeve 51 can support and cover the outside of the piston viscous damper 14 and the shock-absorbing spring 15. Due to the large amount of dust at the construction site and the problem of splashing of cement mortar, the rubber sleeve 51 can play a role in blocking dust, and the spring piece 53 can support the rubber sleeve 51 from the inside.

The vertical axis 41 and the wheel frame 42 on the vertical axis 41 can make the wheel frame 42 rotate, and rely on multiple universal wheels 43 connected to the wheel frame 42 to facilitate the staff to move the lamp stand, so that the staff can adjust the lighting position and area. When in use, the staff can rotate the screw 24, and the thread directions of the two ends of the screw 24 are opposite, so that the screw sleeves 23 at both ends of the screw 24 can be driven to move closer and farther away from each other, thereby driving the fixed arm 21 to rotate, and the screw sleeve 23 can rotate relatively on the fixed arm 21, so that the fixed arm 21 can rotate relatively on the fixed arm 21. The fixing arm 21 is rotated downward or upward by the above-mentioned arrangement, thereby pressing down to fix the base 11, improving the fixing effect and stability. During the downward pressing and rotation of the fixing plate 31, the fixing plate 31 contacts the ground, thereby increasing the contact area with the ground and improving the fixing effect. The support spring 32 is used to play the role of the fixing plate 31, thereby reducing the vertical drooping contact of the fixing plate 31 after the fixing arm 21 is lifted. The rubber sleeve 51 is provided to support and cover the outside of the piston viscous damper 14 and the shock-absorbing spring 15. Due to the high dust at the construction site and the splashing problem of cement mortar, the rubber sleeve 51 can block dust, and the spring piece 53 can support the rubber sleeve 51 from the inside. The frame 62 can slide inside the adjustment seat 61, thereby driving the frame 62 to move up and down in the adjustment seat 61, so that the staff can adjust the height of the lighting lamp 12 according to the lighting height requirements. The frame 62 and the adjustment seat 61 are fixed by bolts passing through the adjustment hole 63.
