By adopting the above technical solution, the floodlight can rotate along the axis of the rotating shaft, the return spring connected to the positioning rod acts on the positioning plate, and the positioning plate drives the positioning rod to move toward the floodlight. The damping pad is closely attached to the floodlight to fix the position of the floodlight. When the angle needs to be adjusted, pull the positioning plate and the positioning rod to both sides, and then turn the flood light. It is avoided that the damping pad and the flood light will not be worn during rotation, the life of the damping pad is improved, and the periodic replacement of the damping pad is avoided. At the same time, in an emergency, the positioning rod can be turned without moving the locating rod, and the floodlight can be turned by increasing the turning force.

To sum up, the beneficial technical effect of the present invention is that the relative position of the rotating shaft is limited by the use of the limit piece, so as to prevent the rotating shaft from sliding relative to the vertical rod.

1. The direction can be changed by turning the flood light and the support rod to realize full-angle flood light. The damping pad defines the position of the floodlight by the action of the spring. When adjusting the angle, move the damping pad and the positioning rod to the direction away from the flood light for adjustment, which reduces the wear of the damping pad and prolongs the service life;

2. Increase the design of transmission gear, driving gear and driven gear. By rotating the turntable, the driving rod and the driving gear are driven to rotate, and finally the support rod is driven to rotate, so as to realize the adjustment of the horizontal angle, and the adjustment is more accurate. By adding a screw and a damping sheet, the position of the gear and the support rod can be limited. Because the damping sheet squeezes the gear through the action of the screw, the wear of the damping sheet does not affect its normal operation.

When rotating, the angle of the flood light 1 in the horizontal direction will be changed, which achieves the effect of adjusting the angle. The rotation direction of the turntable 602 is the same as the rotation direction of the support rod 4 , which is more convenient for the user. When adjusting to an appropriate angle, rotate the screw 8, the screw 8 moves downward, the damping sheet 801 at the bottom of the screw 505 is tightly fitted to the upper end surface of the transmission gear 701, the position of the transmission gear 701 is fixed, and the rotation cannot be continued. The positions of the support rod 4 and the bracket 2 are also fixed. The effect of fixing after adjusting the angle is achieved, because the damping sheet 801 is squeezed on the gear by the screw 8, even if the damping sheet 801 is worn during the friction process, it can still be fixed normally.
