Specifically, the positioning protrusion 305 includes a mounting plate that can be snap-fitted into the third mounting recess 3042 and an arc-shaped protrusion provided on the mounting plate that can protrude into the first mounting hole 613. Thus, on one hand, the above arrangement prevents the positioning protrusion 305 from completely extending into the first mounting hole 613, which makes the mounting and dismounting of the positioning protrusion and the first mounting hole difficult; on the other hand, the structure of the first positioning structure 300 is simpler, and the first positioning structure is easy to process and implement, so that the processing cost of the first positioning structure 300 is reduced.

Specifically, when a worker or a user needs to adjust a monitoring angle of the monitoring device mounted on the vehicle body 700, the first positioning structure 300 is covered on the base 610 so that the positioning protrusion 305 extends into one of the first mounting holes 613, and then the support structure 200 is mounted on the first positioning structure 300 and the base 610. Then, the monitoring angle of the image capturing structure 620 is adjusted until the image capturing structure 620 is fully attached to the supporting surface of the supporting structure 200, and the monitoring angle of the image capturing structure 620 is the preset included angle α.

Optionally, there is one third mounting recess 3042; alternatively, the third mounting recess 3042 is plural, and the plural third mounting recesses 3042 are provided at intervals in the circumferential direction of the positioning body 304. Thus, the position of the positioning body 304 can be adjusted by the above arrangement, that is, the positioning protrusion 305 can extend into any one of the first mounting holes 613, so that the structural flexibility of the first positioning structure 300 is improved, and different use requirements and working conditions are met.
