A driving motor 506 is installed on the top of the first mounting seat 5;

[0024] The output end of the driving motor 506 is connected to the adjusting screw 503 on the adjacent side through a coupling, and the inner side of the second mounting seat 501 is rotationally connected to the adjusting screw 503 of the driving motor 506 away through a bearing seat, and the outer side of the adjusting screw 503 is threadedly connected to the threaded adjustment block 507, and the traction rods 508 are symmetrically arranged on both sides of the threaded adjustment block 507, and the two ends of the traction rod 508 are respectively hinged to the threaded adjustment block 507 and the traction block 509 through a connecting block and a pin shaft, and a support rod 6 is inserted through the inside of the traction block 509, and the two ends of the support rod 6 are respectively connected to the support seat 601 on the adjacent side.

[0025] During specific implementation, in order to make the detection tube body 4 quickly and tightly docked with the two ends of the pressure reducing valve, the pressure reducing valve is first placed inside the placement seat 3, and the driving motor 506 on the top of the first mounting seat 5 is started. The output end of the driving motor 506 drives the adjusting screw 503 connected thereto to rotate through the coupling. When the adjusting screw 503 rotates, the transmission action of the transmission roller 504 and the transmission belt 505 drives the adjusting screw 503 inside the second mounting seat 501 to rotate. When the two adjusting screws 503 rotate, they act on the threaded adjustment block 507. The traction of the hinged connection on both sides of the threaded adjustment block 507 is The rod 508 pulls the traction blocks 509 on both sides of the detection tube body 4.
