In addition, an orthogonal projection of end surfaces of both ends of the body portion 510 on a first cross section of the connector 51 along the extending direction of the connecting portion 512 is a zigzag shape. Specifically, the end surfaces of the two ends of the main body 510 may be "Z" shaped or may be zigzag shaped, and a plurality of latches are provided between the end surfaces of the two ends of the main body 510 of the connecting member 51 and the surfaces of the second ends of the first metal pipe 501 and the second metal pipe 502 for engagement through the structure of the "Z" shape or the zigzag shape, so that the bending resistance between the connecting member 51 and the first metal pipe 501 and the second metal pipe 502 at the two ends can be increased.
Preferably, the material of the connecting member 51 is plastic, and since the plastic has thermoplasticity, the connecting member 51 is easy to be extruded, injected, blow molded or the like, so that the end surfaces of the two ends of the main body portion 510 of the connecting member 51 and the surfaces of the second ends of the first metal pipe 501 and the second metal pipe 502 are easy to be made into a form of close contact, and similarly, the outer diameter of the connecting portion 512 is easy to be matched with the inner diameter of the second through hole 5002 of the first metal pipe 501 and the second metal pipe 502, thereby facilitating the production of the ear.
