In the actual process of straightening the tool 400, it is often required to straighten both sides of the tool 400, and a second straightening member 340 is disposed at one third of the curved plate 150, and when the tool 400 needs to be straightened both sides, the expansion block 342 is adjusted to press the expansion block 342 against the surface of the tool 400 to be straightened, and the first straightening member 330 is moved to another third of the curved plate 150, where the inner arc side is different from the second straightening member 340, and pressure is applied to the tool 400 by the pressing block 332, so as to complete the straightening operation of the tool 400.

The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
