The thickness of pipe wall of relatively each carbon fiber connecting tube of the pipe thickness at place, therefore during use, the stress in three directions, which focuses on, to cross
Place, can bear larger stress, and compression strength is big, and during assembly and disassembly, it is not necessary to bolt is fixed, can
Realize fast assembling-disassembling.
It is preferred that the first carbon fiber connecting tube is docked with the 3rd carbon fiber connecting tube straight line, second carbon
Fiber connecting tube is perpendicular with the first carbon fiber connecting tube and the 3rd carbon fiber connecting tube respectively.
It is preferred that intersection and second carbon of the second carbon fiber connecting tube with the first carbon fiber connecting tube
The intersection of fiber connecting tube and the 3rd carbon fiber connecting tube is arc structure.
It is preferred that the arc structure is in outwardly arrangement.
It is preferred that the outwardly arrangement of intersection of the first carbon fiber connecting tube and the 3rd carbon fiber connecting tube, and
The thickness range that the intersection of the first carbon fiber connecting tube and the 3rd carbon fiber connecting tube is outwardly is 1 to 3 millimeter.
It will be become more fully apparent by following description and with reference to accompanying drawing, the utility model, these accompanying drawings are used to explain this
The embodiment of utility model.
