[0021] For the description of the present invention, the non-limiting Figure 1 The marks "front", "rear", "up", "down", "left" and "right" shown in the figure are used to facilitate understanding of the embodiment and are not intended to limit the present invention. Among them, the front-to-back direction represents the horizontal direction, the left-right direction represents the longitudinal direction, and the up-down direction represents the vertical direction.

[0022] Figures 1-4 The embodiment of the present invention is shown as follows: Figure 1 As shown, the cable straightening mechanism 101 includes a support rod 1, a transverse straightening wheel assembly 2, a vertical straightening wheel assembly 3 and a fixed block 4. In this embodiment, the vertical straightening wheel assembly 3 is arranged on the right side of the support rod 1, and the transverse straightening wheel assembly 2 is arranged on the inner left side of the support rod 1, and corresponds to the position of the vertical straightening wheel assembly 3. The cable passes through the vertical straightening wheel assembly 3 and the transverse straightening wheel assembly 2 in turn and then enters the wire inlet pipe 102. The transverse straightening wheel assembly 2 straightens the cable transversely, and the vertical straightening wheel assembly 3 straightens the cable vertically. One end of the fixed block 4 is fixed near the wire inlet pipe 102 of the wire stripping machine 10, and the other end is rotatably connected to the support rod 1. The fixed block 4 is fixed at the position of the wire stripping machine 10, so that the wire inlet pipe 102 corresponds to the transverse straightening wheel assembly 2, so that the cable can enter the wire inlet pipe 102 horizontally.

[0023] The support rod 1 rotates relative to the fixed block 4, and the inlet pipe 102 is pulled out of the wire stripping machine 10 and replaced, and the support rod 1 is rotated and reset relative to the fixed block 4. The support rod 1 is set on the wire stripping machine 10 by the fixed block 4. By setting the support rod 1 to rotate relative to the fixed block 4, when replacing the inlet pipe 102, the support rod 1 is first rotated to one side, the inlet pipe 102 is pulled out of the wire stripping machine 10 and replaced, and then rotated and reset, which facilitates the back and forth replacement of the inlet pipe 102.

[0024] like Figure 2 As shown, in some embodiments, the cable straightening mechanism 101 includes a connecting block 5, which includes a first connecting portion 51 and a second connecting portion 52. The first connecting portion 51 is vertically connected to the second connecting portion 52, so that the connecting block 5 is L-shaped, and the first connecting portion 51 is rotatably connected to the fixed block 4, and the second connecting portion 52 is fixedly connected to the support rod 1. The connecting block 5 can not only enable the support rod 1 to rotate in a specific direction, but also, after rotation, enable the support rod 1 to be spaced a certain distance from the outer wall of the wire stripping machine 10 to avoid hitting the outer wall of the wire stripping machine 10.

[0025] In some embodiments, the cable straightening mechanism 101 includes a rotating shaft 6, and the fixed block 4 includes a side plate 41, an upper top plate 42 and a lower bottom plate 43.

[0026] In some embodiments, a locking member 422 is provided on the upper plate 42. The locking member 422 is used to lock the connecting block 5 and the fixing block 4. A corresponding locking hole 512 is provided on the first connecting portion 51. One end of the locking member 422 passes through the upper plate 42 and is inserted into the locking hole 512. This prevents the support rod 1 from rotating automatically when the inlet pipe 102 is not replaced, thereby ensuring stability during use. The other end of the locking member 422 is exposed from the upper plate 42, making it easy to pull out the locking member 422 when the inlet pipe 102 needs to be replaced.

[0027] The upper top plate 42 is provided with a locking piece 422, and a corresponding locking hole 512 is provided on the first connecting portion 51.

The locking piece 422 is used to lock the connecting block 5 and the fixing block 4.

[0028] In some embodiments, a first elastic reset member 423 extending downward is provided on the upper top plate 42, and the first elastic reset member 423 includes a hollow first reset column, and the first reset column has a first spring and a first ball. The first spring resists the first ball, and a portion of the first ball is exposed from the first reset column. The upper end surface of the first connecting part 51 is correspondingly provided with a first reset hole 513. During the rotational reset process, whether the support rod 1 is reset can be judged by whether the first ball is stuck in the first reset hole 513, thereby ensuring stability during use.

[0029] In some embodiments, the lower base plate 43 is provided with a second elastic return member 432 extending upward, and the lower end surface of the first connecting portion 51 is correspondingly provided with a second return hole (not shown in the figure). The second elastic return member 432 includes a hollow second return column, and the second return column has a second spring and a second ball 4321. The second spring resists the second ball 4321, and a portion of the second ball 4321 is exposed from the second return column. The second elastic return member 432 and the second return hole are used in conjunction with the first elastic return member 423 and the first return hole 513. When the first ball and the second ball 4321 are respectively stuck in the first return hole 513 and the second return hole, the support rod 1 is successfully reset, making the judgment effect safer.
