[0028] Working principle

[0029] When the device is folded, as Figure 4 shown, first loosen the bolts on the fixing holes 17, then rotate the folding rod 13 along the second spring rod 16, pull the first spring connecting rod 14 down along the chute of the spring rod 16. After the folding rod 13 is stuck inside the first spring, release the first spring connecting rod 14, so that the spring rod 16 rebounds and drives the first spring connecting rod 14 to move upward along the chute of the spring rod 16 to lock the folding rod 13, and then tighten the bolts on the fixing holes 17. Open the first buckle 25 and the second buckle 27, so that the lamp body rocker arm 5 gradually rises driven by the cylinder shaft 6. Horizontally place the device so that the rear wheels 2 contact the ground with the anti-slip pad 21, and adjust the angle of the projection lamp body 3 and the light-shielding plates 22 to complete the unfolding.

[0030] When the device is moving, as Figure 5As shown, it is only necessary to set up the device vertically so that the front wheels 1 and the rear wheels 2 are in contact with the ground.

[0031] When the device is unfolded, as Figure 3 shown, retract the light-shielding plate 22 so that the lamp body rocker arm 5 gradually descends driven by the cylinder shaft 6, and fasten the first buckle 25 and the second buckle 27. First, loosen the bolt on the fixing hole 17, pull down the first spring connecting rod 14 along the chute of the spring rod 16, so that the folding rod 13 disengages from the first spring connecting rod 14 and rotates along the second spring connecting rod 15. After rotating and folding, tighten the bolt of the fixing hole 17 to complete the folding.

[0032] In summary, the utility model can conveniently adjust the angle and height, and has the advantages of convenient movement, convenient operation and small occupied space.
