[0022] The guide rail 15 is provided on the other side of the slide 6, and the outer side of the slide 6 is sleeved with a sleeve 12 that moves along the slide 15. A right card knife 10 is fixed to one side of the sleeve 12 by bolts. A plurality of scale lines 13 are provided on the top of the slide 6, and a pointer 11 for indicating the scale is fixed to one side of the sleeve 12 by bolts. Then, the sleeve 12 is pulled to move along the slide 15, and the sleeve 12 will drive the right card knife 10 to move, so that the right card knife 10 is against the edge of the pipe. At this time, the sleeve 12 cannot move. Then, the inner diameter of the pipe is measured by the position indicated by the pointer 11 on the scale line 13. After the inner diameter measurement of the pipe is completed, the stop screw 14 is loosened, and then the pipe is rotated in the V-shaped groove 4. At this time, if the pipe is eccentric, the right card knife 10 will drive the sleeve 12 to move, changing the position indicated by the pointer 11 on the scale line 13. Therefore, whether the pipe is eccentric can be measured by whether the right card knife 10 moves, thereby facilitating the detection of the eccentricity of the pipe.

[0023] In the present invention, the guide components are multiple guide rods 1, multiple guide rods 1 are welded to the bottom of the support frame 3, and the guide rod 1 passes through the frame body 2. The support frame 3 will drive the guide rod 1 to move upward, so that the support frame 3 moves vertically upward to ensure the vertical movement of the support frame 3. The guide assembly includes two guide rods 2 7. The two guide rods 2 7 are fixed to the upper surface of the frame body 2 by bolts, and the guide rods 2 7 pass through the slide 6. Two guide sleeves 5 are welded to the inner walls of both sides of the slide 6, and the guide rods 2 7 pass through the guide sleeves 5. When the slide 6 moves, it will move horizontally along the guide rods 2 7, thereby ensuring the horizontal movement of the slide 6. A threaded hole is opened on one side of the slide sleeve 12, and the screw in the threaded hole The groove is connected with a stop screw 14 for locking the sleeve 12. When the right clamping knife 10 is against the edge of the pipe, the stop screw 14 is tightened to make emergency contact between the stop screw 14 and the slide 6 to lock and fix the sleeve 12, so as to facilitate the staff to observe the length measured by the scale line 13. A plurality of mounting grooves 17 are provided on both sides of the V-shaped notch 4. The plurality of mounting grooves 17 are rotatably connected with rollers 16. During the rotation of the pipe, the rollers 16 will rotate due to friction, thereby reducing the friction of the pipe rotation and reducing the wear on the pipe. A knob for rotating the threaded rod 8 is welded to the bottom end of the threaded rod 8, and a plurality of evenly distributed anti-slip grooves are provided on the outside of the knob.

[0024] The working principle of the present invention is as follows: when in use, the pipe is placed in the V-shaped groove 4, and then the left card knife 9 and the right card knife 10 are inserted into the pipe and the left card knife 9 is pressed against the pipe, and then the slide 6 is blocked by the hand, and then the threaded rod 8 is rotated. The threaded rod 8 is engaged with the frame body 2 to push the support frame 3 to move upward, and the support frame 3 drives the guide rod 1 to move upward, so that the support frame 3 moves vertically upward. In the process of upward movement, the support frame 3 will push the pipe in the V-shaped groove 4 to move upward, and in the process of upward movement of the pipe, if the left card knife 9 is not at the center line of the pipe, a gap will be generated between the edge of the pipe and the left card knife 9. Then the slide 6 is pushed by hand to move horizontally along the guide rod 2 7 so that the left card knife 9 continues to press against the edge of the pipe, and this cycle is repeated until the left card knife 9 is located at the center line of the pipe and presses against the left card knife 9 and cannot move upward. When the tool is in the center of the pipe, the center line of the pipe can be aligned, which is convenient for the staff to find the center line of the pipe. Then, the sliding sleeve 12 is pulled to move along the slide 15. The sliding sleeve 12 will drive the right card knife 10 to move, so that the right card knife 10 is against the edge of the pipe. At this time, the sliding sleeve 12 cannot move, and the stop screw 14 is tightened to make the stop screw 14 and the slide 6 make emergency contact to lock the sliding sleeve 12. Then, the inner diameter of the pipe is measured by the position indicated by the pointer 11 on the scale line 13. When the inner diameter measurement of the pipe is completed, the stop screw 14 is loosened, and then the pipe is rotated in the V-notch 4. At this time, if the pipe is eccentric, the right card knife 10 will drive the sliding sleeve 12 to move, changing the position indicated by the pointer 11 on the scale line 13. The eccentricity of the pipe can be measured by whether the right card knife 10 moves, which is convenient for detecting the eccentricity of the pipe.
