[0028] A sealing sleeve is fixedly connected to the outside of the hose 10, and an air pressure detector 11 is fixedly connected to the inside of the right convex block 5;

[0029] The right convex block 5 can detect the air pressure through the air pressure detector 11;

[0030] The right side of the air pressure detector 11 is fixedly connected with a display meter 12 located on the right side of the right lateral movement block 4;

[0031] The air pressure detected by the air pressure detector 11 can be displayed by means of a display meter 12;

[0032] The inside of the housing 1 is rotatably connected with a threaded cross bar 13, and the outer side of the threaded cross bar 13 is threadedly connected with a vertical block 14;

[0033] The vertical block 14 can be moved by the threaded crossbar 13;

[0034] The vertical block 14 is adapted to the transport pipe 7, and a plurality of nozzles 15 are fixedly connected to the front of the vertical block 14;

[0037] By turning the handle 17 , the extension shaft 16 can be rotated.

[0038] Working principle:

[0039] Step 1: Start the dual-axis motor 2, so that the output ends on both sides of the dual-axis motor 2 drive the opposite threaded rods 3 to rotate, and the rotation of the opposite threaded rods 3 drives the two transverse blocks 4 to move, and then the transport pipe 7 is clamped on the outside of the two convex blocks 5, so that the sealing ring 6 and the transport pipe 7 form a closed space;

[0040] Step 2: Start the air pump 9, so that the output end of the air pump 9 presses into the inside of the transport pipe 7 through the hose 10. After the pressing is completed, observe the air pressure gauge of the air pump 9 and the display gauge 12. When the two gauges are consistent, replace the next pipe;

[0041] Step 3: When the two meters are inconsistent, start the nozzle 15 to spray soapy water to the outside of the transport pipe 7, then turn the handle 17 to drive the threaded cross bar 13 to move through the extension shaft 16, and then the threaded cross bar 13 drives the vertical block 14 to move, and the movement of the vertical block 14 causes the nozzle 15 to move left and right, so that the outside of the transport pipe 7 is covered with foamy water, and then observe the outside of the transport pipe 7. When bubbles are emitted due to air pressure leakage at a certain point, it is the damaged point.
