The drive component 3 is mounted on the base 1, and its driving end is connected to the drive rod 2. Both ends of the drive rod 2 are provided with external threads 21, and the thread directions of the external threads 21 at both ends of the drive rod 2 are opposite. The clamping components 4 have threaded holes 412, and the two clamping components 4 are respectively disposed at both ends of the drive rod 2, and both ends of the drive rod 2 pass through... Corresponding to and threadedly connected to the threaded hole 412, the two clamping members 4 detachably clamp the corresponding ends of the n-shaped part 5. The driving member 3 drives the driving rod 2 to rotate forward so that the two clamping members 4 move closer to each other and narrow the distance between the two ends of the n-shaped part 5, or rotates backward so that the two clamping members 4 move further apart and widen the distance between the two ends of the n-shaped part 5. In this way, the two clamping members can clamp the two ends of the n-shaped part respectively, and then the driving member drives the driving rod to rotate forward or backward to adjust the distance between the two ends of the n-shaped part 5, thereby realizing the shaping of the n-shaped part.
[0031] like Figure 2 As shown, the lower end of the base 1 in the above technical solution is provided with anchor bolts 11, so that the level of the base can be easily adjusted when it is placed.
[0032] like Figures 1-3 As shown, the clamping member 4 in the above technical solution includes a U-shaped seat 41, a clamping block 42, and a pressing bolt 43. The inner groove of the U-shaped seat 41 is perpendicular to the drive rod 2. A protrusion 411 is provided on the bottom wall of the U-shaped seat 41, and a threaded hole 412 is provided on the protrusion 411. The clamping block 42 is slidably disposed on the inner bottom wall of the U-shaped seat 41 in the left-right direction. The pressing bolt 43 penetrates the groove wall on one side of the U-shaped seat 41 in the left-right direction and is threadedly connected to it. Its threaded section is located inside the U-shaped seat 41 and is rotatably connected to the corresponding side of the clamping block 42. The area between the clamping block 42 and the groove wall on the other side of the U-shaped seat 41 forms a clamping opening corresponding to the clamping member 4. Thus, by turning the pressing bolt, the corresponding end of the n-shaped workpiece can be clamped in the clamping opening.

[0036] The extrusion bolt 43 mentioned in the above technical solution is an internal hex bolt, which has a simple structure.
[0037] In the above technical solution, the side walls on both sides of the clamp are friction surfaces, which can prevent the n-shaped part from slipping when clamped by the clamping device.
[0038] In the above technical solution, the seat 1 is hollow inside, and the driving component 3 is disposed inside the seat 1 and is connected to the middle part of the driving rod 2 for transmission, so that the entire n-shaped part correction fixture is more compact and aesthetically pleasing in structure.

Its structure is simple, and the worm can be manually and flexibly rotated to adjust the distance between the two ends of the n-shaped part.
[0041] In the above technical solution, the front end of the worm 32 extends out of the seat 1 and forms a handle, which makes it more convenient to manually rotate the worm.
