The whole connecting part can move upwards relative to the body through the avoiding section, and the bottoms of the two adjacent bodies are parallel and level when the two adjacent bodies are connected.

In the polypropylene profile, a first transition part for smooth transition is arranged between the avoidance section and the body.

The first transition part is of a round angle structure.

In the polypropylene section bar, a convex contact section II is arranged at a U-shaped port at the inner side of the connecting part, the contact section I and the contact section II are symmetrically arranged at two sides of the connecting part, and a transition part II in smooth transition is arranged between the avoiding section and the contact section II.

The contact area between the contact section II and the body can be increased, and the transition part is of a round angle structure.

Compared with the prior art, the polypropylene section bar creatively connects the plurality of bodies in series in sequence through the first connecting piece and the second connecting piece, so that the width of the section bar can be changed according to actual conditions, and the applicability of the section bar is higher.

Meanwhile, the second connecting piece is embedded in the connecting part of the first connecting piece, so that the structure is compact, and the practical value is high.
