The driving rod 26 is T-shaped, and the bottom end of the latch 27 penetrates into the interior of one of the clamping grooves 25 and its diameter is consistent with the diameter of the clamping groove 25.

[0036] Working principle: When in use, place the special-shaped pipe to be inspected on the placement plate 12, and then replace the corresponding punching detection rod 11 according to the size of the hole on the special-shaped pipe fitting. The staff manually rotates the driving rod 19 to make the driving rod 19 drive the worm 18 to rotate forward. At this time, the worm gear 7 engaged with the worm 18 drives the connecting shaft 6 to rotate, and then the connecting shaft 6 drives the bevel gear 18 to rotate, so that the four bevel gears 21 engaged with the bevel gear 18 respectively drive the four mounting shafts 20 and the threaded rod 4 to rotate, so that the four L-shaped connecting blocks 5 move inward along the four limit slots 9 until the driving rod 19 is rotated. At this time, one side of the L-shaped connecting block 5 is completely disengaged from the fixing slot 23, and the fixing of the mounting block 22 is released, thereby facilitating the removal of the punching detection rod 11.

[0037] Then, the installation block 22 to be replaced is inserted into the placement slot 10. At this time, the staff manually rotates the driving rod 19, so that the driving rod 19 drives the worm 18 to reverse, and then the four L-shaped connecting blocks 5 move toward the placement slot 10 until the driving rod 19 can no longer be rotated. At this time, one side of the four L-shaped connecting blocks 5 is respectively engaged in the four fixing slots 2 23, and the four connecting blocks are fixed by the self-locking of the worm gear 7 and the worm 18;

[0038] After the replacement of the punching detection rod 11 is completed, the height of the punching detection rod 11 is adjusted according to the size of the special-shaped tube. By pulling out the pin 17, the connection frame 16 is released. At this time, the connection frame 16 is slid upward, so that the connection frame 16 drives the hollow block 3 to move upward until it moves to a suitable height. At this time, the pin is inserted into the corresponding fixing groove to fix the position of the hollow block 3, and the height adjustment of the punching detection rod 11 is completed.

[0039] Then the electric telescopic rod 28 is started to drive the clamping pad 29 to move downward and abut against the outside of the special-shaped tube. At this time, the two electric telescopic rods 1 are started again to respectively drive the two hollow blocks 3 and the two punching detection rods 11 to move toward the corresponding two ends of the special-shaped tube until one end of the punching detection rod 11 extends into the interior of one end of the corresponding special-shaped tube and performs punching detection;

[0040] When the other two ends of the special-shaped tube need to be inspected and fixed, the two electric telescopic rods are first started to drive the two punching detection rods 11 to retract until they are separated from the special-shaped tube, and the second latch 27 is pulled out. The fixation of the second driving rod 26 is released, and the second driving rod 26 is rotated to drive the second electric telescopic rod 28 and the clamping pad 29 to rotate, so that the special-shaped tube drives the placement plate 12 to rotate, so that the other two ends of the special-shaped tube correspond to the positions of the two punching detection rods 11 respectively. At this time, the second latch 27 is inserted into the corresponding clamping groove 25 to fix the second driving rod 26. Finally, the second electric telescopic rod 28 can be started to make the two punching detection rods 11 perform punching inspection on the other two ends of the special-shaped tube.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
