Above the first supporting wheel 3 on the movable plate 2, there is a slotted groove 4. A movable block 5 is slidably connected in the slotted groove 4. A pressing wheel 6 is rotatably connected to the back surface of the movable block 5. At the upper end of the movable plate 2, there is a height adjustment assembly for adjusting the height of the movable block 5. Trapezoidal grooves 7 are provided in the middle sections of the sides of the first supporting wheel 3 and the pressing wheel 6. The height adjustment assembly includes an adjusting rod three 18, a transmission plate 19, and a transmission rod 20. The upper end surface of the movable block 5 is rotatably connected to the adjusting rod three 18. Above the movable plate 2, there is a transmission plate 19. Both ends of the transmission plate 19 are connected to the movable block 5 through the transmission rod 20. The transmission rod 20 is slidably connected to the movable plate 2. The adjusting rod three 18 is threadedly connected to the transmission plate 19. A handwheel three 21 is provided at the upper end of the adjusting rod three 18.

[0031] When clamping and positioning the pipe, place the pipe to be straightened between the pressing wheel 6 and the first supporting wheel 3. Rotate the adjusting rod three 18 through the handwheel three 21. The adjusting rod three 18 drives the transmission plate 19 threadedly connected thereto to move on the adjusting rod three 18. During the movement, the transmission plate 19 drives the transmission rod 20 to move. The transmission rod 20 also prevents the transmission plate 19 from rotating following the adjusting rod three 18. The transmission rod 20 drives the movable block 5 to move in the slotted groove 2. The movable block 3 drives the pressing wheel 6 to move towards the first supporting wheel 3. Since trapezoidal grooves 7 are provided on both the pressing wheel 6 and the first supporting wheel 3, the pressing wheel 6 and the first supporting wheel 3 can perform good clamping and positioning on pipes of different specifications and sizes.

[0032] At the rear end of the upper end surface of the bottom plate 1, there is a fixing plate 8. At both ends of the front surface of the fixing plate 8, a second supporting wheel 9 is rotatably connected. The position adjustment assembly adjusts the horizontal position of the movable plate 2. The position adjustment assembly includes a second sliding groove 14 and an adjusting rod two 15. At the front end of the upper end surface of the bottom plate 1, there is a second sliding groove 14. An adjusting rod two 15 is rotatably connected in the second sliding groove 14. The adjusting rod two 15 extends along the length direction of the second sliding groove 14. One end of the adjusting rod two 15 extends out of the second sliding groove 14. A handwheel two 16 is provided at the end of the adjusting rod two 15 that extends out of the second sliding groove 14. A slider 17 is slidably connected in the second sliding groove 14. The adjusting rod two 15 is threadedly connected to the slider 17. The slider 17 is connected to the movable plate 2.

[0033] When clamping and positioning the plate, rotate the adjusting rod two 15 through the handwheel two 16, so that the slider 17 threadedly connected thereto moves in the second sliding groove 14. The slider 17 drives the movable plate 2 to move, thereby adjusting the distance between the first supporting wheel 3 and the second supporting wheel 9, making the front and rear ends of the lower end surface of the first supporting wheel 3 and the second supporting wheel 9 fit the plate. By adjusting the height of the pressing wheel 6, the pressing wheel 6 presses and positions the plate, thereby realizing the positioning of the plate.
