[0033] Specifically, the rear side of the support table 2 is fixed with a concave handle 11 for lifting.

[0034] Specifically, the outer side of the concave handle 11 is sleeved with a rubber layer for increasing friction.

[0035] Specifically, the rear side of the support table 2 is provided with a groove, and a spring positioning pin 10 is fixedly installed in the inside of the groove. The outer side of the T-shaped sliding block 9 is provided with a positioning hole 14 matched with the spring positioning pin 10. The spring positioning pin 10 is arranged to enable the T-shaped sliding block 9 to be stably positioned in the T-shaped groove.

[0036] Specifically, the rotating structure includes a rotating column 15, a concave block 13 and a fixed block 16. The bottom of the T-shaped sliding block 9 is provided with a hole groove. One end of the rotating column 15 is rotatably installed in the hole groove. The other end of the rotating column 15 is fixed with the concave block 13. The fixed block 16 is rotatably installed in the concave block 13. The small-diameter end of the multi-section telescopic rod 3 is fixed with the fixed block 16. As can be known from the above connection relationship, the T-shaped sliding block 9 can rotate relative to the concave block 13. The T-shaped sliding block 9 can drive the projector 1 on the support table 2 to rotate. The concave block 13 can rotate relative to the fixed block 16, so as to adjust the projection angle of the projector 1.

[0037] Specifically, the support mechanism includes a fixed ring 6, a moving ring 4 and a plurality of support rods 5.
