Title: METERING LINE RETRACTOR
Abstract:
A metering line retractor, comprising a retractor body (2) provided with a linked rotating shaft (21), a linkage hole provided on the retractor body, an external thread provided on the linked rotating shaft, and a spiral structure provided on the wall of the linkage hole and fitting the external thread, the linkage hole being connected to the external thread, thus allowing the retractor body to move in the direction of extension of the linked rotating shaft while the retractor body is rotating with the linked rotating shaft as the axis. A line concealing groove is provided on the retractor body, the pitch of the line concealing groove is equivalent to the pitch of the external thread and has a same spiral direction, and the line concealing groove spirally runs in the direction of extension of the linked rotating shaft. When working, an externally provided metering line is connected with the retractor body, the rotation of the retractor body makes the metering line to fall into the line concealing groove, the retractor body also moves in the direction of extension of the linked rotational shaft, and the angle between the metering line and the linked rotational shaft is kept unchanged, thus preventing errors brought forth by changes in the angle. The metering line retractor is used for retracting the metering line.
