separated from the threaded hole 802 by reversely rotating the puncture needle 7, the puncture needle 7 can be taken out at the moment, if the inside of the drainage main pipe 1 is blocked in the later drainage process, the movable block 801 can be connected with an external tool to push the movable block 801 to enter the drainage hole 102 for dredging operation, finally, the drainage main pipe 1 needs to be fixed, the lantern ring 304 is rotated to move along the track of the outer walls of the first fixing piece 305, the second fixing piece 306 and the third fixing piece 307 towards the direction far away from the connecting ring block 303, this in-process lantern ring 304 can be to a stationary blade 305, No. two stationary blades 306, No. three stationary blades 307 form the extrusion and make it be close to each other, a stationary blade 305, No. two stationary blades 306, No. three stationary blades 307 laminate each other and make its inner wall can be responsible for 1 with the drainage and closely laminate, make the drainage be responsible for 1 and form fixed connection with fixed establishment 3, the drainage is responsible for 1 and is the relatively fixed state with the human body promptly, can avoid the drainage to be responsible for 1 and take place the displacement phenomenon in the drainage in-process afterwards, No. two spread groove 404 or shunt tubes 5 on the drainage is responsible for 1 accessible connecting sleeve 401, external drainage equipment is connected to multi-functional joint 6, so that adapt to different drainage
