The hydraulic cylinder 2 is reinforced by the reinforcement plate 11 to reduce the probability of its tipping over, and the fixing effect is better.

[0030] The adjusting mechanism comprises a connecting block 14, a connecting groove 15, a gear 16 and a rack 17. The connecting block 14 is fixedly mounted on the top of the hydraulic cylinder 2. The connecting groove 15 is opened on the top of the connecting block 14. The connecting groove 15 is rotatably connected to the output rod of the supporting plate 3.

After adjustment, assemble the rack 17 on the connecting block 14 so that the rack 17 limits the gear 16, thereby ensuring that the support plate 3 does not rotate, and complete the angle adjustment of the license plate recognition component 4. The adjustment is relatively quick.
