Wherein, helical spring head 200 one end is located the body and with body rotatable coupling, and the helical spring head 200 other end stretches out outside the first end of body 100, and helical spring head 200 is conical helical spring. The driving spring 300 is located in the tube 100, the driving spring 300 is rotatably connected to the tube 100, and the driving spring 300 can drive the spiral spring head 200 to rotate when rotating. The suction assembly 400 is disposed at the second end of the tubular body 100 for removing loose blockages in the tubular body 100. Specifically, in the suction state, the suction assembly 400 applies a suction force to the unclogged blockage within the tube 100, wherein the direction of the suction force is directed from the first end of the tube to the second end of the tube. The unclogged blockages in the tube 100 move toward the second end of the tube 100 under the suction force of the suction assembly 400, and are discharged out of the tube 100.
