A micro motor 115 is fixedly connected to the bottom of the left pulley 113, and the micro motor 115 drives the left pulley 113 to be active. Because of the drive of the belt 114, the two pulleys 113 rotate synchronously, thereby driving the two connecting rods 104 and the two driving gears 103 to rotate synchronously. When the two driving gears 103 rotate, the meshing rotating gear ring 101 is driven to rotate, and the detection ring 107 rotates accordingly, thereby performing a ring-mounted detection test on the pipeline, which is more convenient and can quickly locate the points where the pipeline is not tight enough.
