An extension plate 13 is integrally fixed to the lower side of the left end of the foot hook plate 12. A foot hook groove 14 is provided at the left end of the foot hook plate 12, and sliding rib plates 17 are symmetrically fixed at the front and rear positions of the lower right end of the foot hook plate 12. This design solves the problem that in the subsequent maintenance process of the original camera, the staff need to use a construction vehicle to lift the vehicle flow collection camera for disassembly and assembly, which is costly, time-consuming and labor-intensive.

[0020] As the first embodiment of the utility model: the upper end of the hollow support rod 4 is installed with a bearing seat by bolts, and the upper end of the threaded rod 8 is installed in the bearing seat. The added bearing seat can assist the threaded rod 8, making the threaded rod 8 more stable when rotating. The right end of the limit lifting block 10 is fixed to the first high-strength nut 6 and the second high-strength nut 7. Through the added limit lifting block 10, when the first high-strength nut 6 and the second high-strength nut 7 move outside the threaded rod 8 through the thread principle, they can be lifted and moved in the strip groove 9, thereby driving the foot hook plate 12 to move upward. A handle 15 is fixed on the upper side of the front end of the hollow support rod 4.
