    • An installation member for service ducts includes a control disk (2) with rotating shaft (16) which is rotatably mounted in a housing (1). Screw thread-type trip cams (3) are formed in the outer side of control disk (2). Two Z-shaped clamping levers (4) are placed in a central longitudinal slot in the bottom of housing (1). The upper arms (6) of the clamping levers (4) each engage in one of the trip cams (3), wherein a bent portion (8) at the end of the arm and a ramp (17) at the trip cam (3) facilitates the conversion of the rotating movement into a tilting movement. The lower arms (5) of the clamping levers (4) engage in one of the longitudinal grooves (19) having an approximately T-shaped cross-section provided on the rear wall (25) of the ducts.
    • 用于维修管道的安装构件包括具有可旋转地安装在壳体(1)中的旋转轴(16)的控制盘(2)。 螺旋式跳闸凸轮(3)形成在控制盘(2)的外侧。 两个Z形夹紧杆(4)放置在壳体(1)的底部的中心纵向槽中。 夹紧杆(4)的上臂(6)各自接合在一个跳闸凸轮(3)中,其中臂的端部处的弯曲部分(8)和跳闸凸轮(3)处的斜面(17) )有助于将旋转运动转换成倾斜运动。 夹紧杆(4)的下臂(5)与设置在管道的后壁(25)上的具有大致T形截面的纵向槽(19)中的一个接合。
