[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The flange which is easy to maintain, pulls the pull ring on the plug rod to make the plug rod move horizontally, and the movement of the plug rod drives the limit rod to contract through the cooperation of the connecting steel wire, and then the position of the plug rod is fixed by rotating the bearing member, and then the protrusion is inserted into the connecting hole, and then the bearing member is reset and the limit rod is inserted into the connecting hole through the elastic force of the limit spring, and the sealing connection between the pipe body 1 and the pipe body 2 is realized through the cooperation of the sealing gasket, thereby greatly improving the practicality of the flange which is easy to maintain.

[0013] 2. The flange which is easy to maintain is arranged by placing the pipe body 1 fixedly connected with the first flange and the pipe body 2 fixedly connected with the second flange on an auxiliary table, and then starting the motor to rotate the screw rod, and the rotation of the screw rod causes the rubber plate to push the pipe body 1 and the pipe body 2 to align with each other, so that the subsequent protrusions can be inserted into the connecting holes, avoiding the tedious manual auxiliary pipe body alignment, thereby greatly improving the convenience of the subsequent connection between the first flange and the second flange, and the mutual cooperation of multiple protrusions effectively avoids the occurrence of the pipe body 1 and the pipe body 2 being disconnected due to damage of a single protrusion.
