Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging, in particular to a manual pipeline dredging device. Background Art

[0002] A pipe dredge is a tool used to clear and unclog sewers. It comes in various types, including wire and pneumatic, and is an indispensable tool in modern household life. Drain pipes in bathrooms and kitchens often become clogged due to long-term use, necessitating the use of a pipe dredge. Currently, the most common type is a hand-cranked spring dredge, which includes a housing containing a retractable spring. The spring is inserted into the pipe, locked when it reaches the blockage, and then rotated and agitated to wrap the blockage around the spring. Finally, the spring is pulled out to unclog the pipe. Because the spring has no support at the end when inserted into the toilet pipe, rotating and agitating after the spring is locked can contact the glaze inside the toilet bowl, easily damaging the glaze and making subsequent toilet use more prone to blockage.
