[0016] 1. The utility model opens a transmission on the upper side of the adjustment seat. When the LED light source needs to be adjusted, the user can turn the knob, and the knob will drive the transmission worm to rotate through the second rotating shaft. The worm gear transmission of the transmission worm and the transmission worm wheel can make the first rotating shaft rotate, and the first rotating shaft will drive the LED light source to rotate synchronously, so that the illumination angle of the LED light source can be adjusted. At the same time, since the worm gear transmission of the transmission worm and the transmission worm wheel has a certain self-locking property, the LED light source cannot rotate and can only be adjusted by rotating the knob, thereby ensuring stability.

[0017] 2. The utility model has a guide rod welded on the upper end of one side of the adjustment seat, and a sliding clamp is slidably provided on the outside of the guide rod. Before turning the knob to make the second rotating shaft rotate synchronously, it is necessary to pull the sliding clamp to compress the reset spring. When the adjustment is completed, the sliding clamp is released, and the sliding clamp can clamp the annular block on the outer wall of the second rotating shaft under the elastic action of the reset spring. The friction force can be increased by the anti-slip pad, so that the clamping and fixing are more firm, so that the second rotating shaft can be limited, and the random rotation of the second rotating shaft after the adjustment can be avoided, thereby further improving the stability of the LED light source after adjustment.

[0018] 3. The utility model has a storage groove inside the base. In daily use, the user can drive the adjustment seat to raise or lower the height through the electric telescopic rod, and the adjustment seat can be moved into the storage groove for storage, thereby facilitating the storage of the adjustment seat.
