In this way, the above arrangement makes the shape of the car-blocking structure 10 more diverse to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff. At the same time, multiple connecting rods 20 can improve the overall structural stability of the car-blocking assembly.

[0042] In this embodiment, the car blocking structure 10 is a triangular plate and has three mounting holes 11, which are arranged one-to-one with the three corners of the triangle. There are three connecting rods 20, which are arranged one-to-one with the three mounting holes 11.
