发明名称 Drain-clearing device
摘要 A drain clearing device includes a first hollow tube having opposed first and second ends and a plunger head coupled to the first end. A second hollow tube includes a first end operatively coupled to the first end of the first tube, the first and second tubes being configured for telescoping movement between extended and retracted configurations. A snaking member is situated in the first and second tubes for movement between storing and operating configurations when the tubes are moved between extended and retracted configurations, respectively. A crank handle connected to the snaking member enables a user to rotate and extend the snake as needed. A plug is included for separating an inner tube area from an inner area of the plunger head and to prevent water spillage from the tubes.
