This creation is a retractable tube machine including a base, a control box, a clutch unit, a transmission unit, a reel unit, a reciprocating unit and a power unit. When the tube is retracted, the clutch unit is controlled by the control box to allow the clutch unit to drive the transmission unit. The reel unit and the reciprocating mechanism act with the transmission unit. At this time, the hose can reciprocate between the two ends of the reel unit according to the reciprocating mechanism, so that the hose is neatly arranged and wound around the reel unit. The hoses are neatly wrapped around the reel unit, and the reciprocating movement of the reciprocating mechanism makes the resistance of the tube discharge low and smooth.本創作為一種收放管機包括有基座、控制盒、離合單元、傳動單元、捲盤單元、往復單元及動力單元，收管時經由控制盒控制離合單元，讓離合單元帶動傳動單元，令捲盤單元及往復機構隨傳動單元動作，此時，軟管可依往復機構在捲盤單元的兩端之間往復移動，使軟管整齊排繞收在捲盤單元，放管時，可因軟管整齊排繞在捲盤單元，加上往復機構的往復運動，使得放管的阻力低且順暢。
