It extends along the circumference of the auxiliary guide ring and passes through the radial sides of the auxiliary guide ring. Its width is greater than the width of the avoidance gap. The cutting wire in the limiting ring groove is output outward from the wire delivery outlet during operation, and a certain offset space is provided by the wire delivery outlet to its output process.

[0015] In one embodiment of the present invention, the circumferential length of the wire transport outlet is greater than the circumferential length of the wire transport inlet, so that the cutting wire has a larger offset space at the wire transport outlet.

[0016] In one embodiment of the present invention, a group of locking bolt holes are opened in the auxiliary guide ring, and each locking bolt hole is located on the side of the guide groove. They are arranged sequentially along the circumference of the auxiliary guide ring and radially penetrate both sides of the auxiliary guide ring. The auxiliary guide ring can be fixed to the support seat by a locking bolt adapted therewith.

[0017] In one embodiment of the present invention, a group of hollow recesses are provided on the inner wall of the auxiliary guide ring, and the hollow recesses are arranged sequentially along the circumference of the auxiliary guide ring. They are radially recessed into the interior of the auxiliary guide ring and extend along the circumference of the auxiliary guide ring. The locking bolt hole and the hollow recesses are arranged at intervals, and the operating status of the cutting wire and the guide wheel body can be inspected through the hollow recesses.

[0018] The advantages of the present invention are:

[0019] The auxiliary guide ring with guide grooves and avoidance gaps in the cutting wire guide wheel assembly is sleeved on the support seat and wrapped around the outside of the guide wheel body, which not only provides a clear wire threading path for the cutting wire, but also plays a role in guiding and supporting the cutting wire. The avoidance gap extends along the bottom of the guide groove and corresponds to the position of the limiting ring groove. Its width is consistent with the widest part of the limiting ring groove, ensuring that the cutting wire can pass through smoothly without obstruction. Under the guidance of the avoidance gap, the cutting wire can accurately enter the limiting ring groove, and the guide wheel body guides the conveying process of the cutting wire to improve the wire threading efficiency. The width of the wire transport inlet and the wire transport outlet is greater than the width of the avoidance gap, which provides sufficient offset space for the cutting wire in the limiting ring groove during operation, ensuring that the cutting wire can be smoothly input into the limiting ring groove from the wire transport inlet and can be smoothly output from the wire transport outlet, thereby ensuring operational stability.
