[0027] Specifically, when fixing the pipeline to be docked, place the pipeline on the limit roller 202, and then rotate one end of the threaded rod 407. The threaded rod 407 is provided with left - hand and right - hand threads, and the sleeve blocks 406 are threadedly connected to different threads. By rotating the threaded rod 407, the sleeve blocks 406 are moved. The movement of the sleeve blocks 406 pulls the clamping column 409 to move through the limit seat 408, so as to facilitate the rotation of the docking column 4 on the arm plate 401 on the side plate 305. By rotating the arm plate 401, the clamping block 403 tightly fits on the outer wall of the pipeline, so as to facilitate keeping the pipeline and the electromagnetic head 101 on the same axis position.

[0028] The working principle of the present invention: When the cut - off valve body 1 needs to be installed, first place the valve pipe 102 inside the arc - shaped groove 204, and then rotate the clamp 206. By rotating the clamp 206, the pressing block 207 fits on the pipeline. Then, the other end of the clamp 206 is fixedly connected to a cross bar 208, and a frame 209 is rotatably connected to the cross bar 208. By rotating the frame 209, the clamping block 211 on the lead screw 210 is located at the bottom position of the card slot 213. Then rotate the lead screw 210. By rotating the lead screw 210, the clamping block 211 is clamped inside the card slot 213, so as to facilitate fixing the support plate 2 on the electromagnetic head 101; When it is necessary to move the side plate 305, first pull the snap ring 311. The snap ring 311 is fixedly connected to the insertion rod 310. By pulling the snap ring 311, the insertion rod 310 is moved. The other end of the insertion rod 310 is fixedly connected to the limit block 313, and the teeth 314 on the limit block 313 are clamped on the gear 308 by the elastic force of the spring 312. By pulling the snap ring 311, the teeth 314 are disengaged from the tooth groove position of the gear 308, and then the rotating rod 307 is rotated. The rotation of the rotating rod 307 facilitates the adjustment of the position of the side plate 305; When fixing the pipeline to be docked, place the pipeline on the limit roller 202, and then rotate one end of the threaded rod 407. The threaded rod 407 is provided with left and right hand threads, and the sleeve blocks 406 are threadedly connected to different threads. By rotating the threaded rod 407, the sleeve blocks 406 are moved. The movement of the sleeve blocks 406 pulls the clamping posts 409 through the limit seats 408, so that the docking posts 4 on the arm plate 401 can rotate on the side plate 305. By rotating the arm plate 401, the clamping blocks 403 are tightly attached to the outer wall of the pipeline, so as to facilitate keeping the pipeline and the electromagnetic head 101 on the same axis position.
