However, taking specific pipeline systems such as stair handrails, building internal and external wall handrails, corridor railings, etc. as examples, existing elbow connectors made of stainless steel and other materials generally use direct welding, threaded fixing and other methods. These methods require a lot of manpower and material resources during the installation process. Because there is no socket-type straight pipe section structure at both ends, it cannot be used for socket welding or socket bonding when the inner and outer sockets are inserted into the pipeline. During the installation process, the existing elbows are very inconvenient in aligning the pipeline ports and adjusting the angles, and the work efficiency is low.
