Problems solved by technology

[0002] In the prior art, there are many structures for connecting pipes through connecting fittings. The more common one is to insert the pipes into the connecting fittings, and then directly connect and fix the pipes and connecting fittings with fasteners such as screws and rivets, and use the above method to connect the pipes. , the installation steps are more complicated, and the stress at the joint is mainly concentrated on the fasteners, and the stress points of the fasteners are susceptible to shear force and fracture failure
