[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a pipe mouth trimming device for PVC wire pipe processing, comprising a base 1, a support plate 2, a connecting pin 3, a supporting disc 4, an inner support rod 5 and a ring cutting mechanism 6, wherein the support plate 2 is arranged on the base 1, the axis of the connecting pin 3 is arranged horizontally, and the connecting pin 3 is fixedly connected to the support plate 2, the axis of the supporting disc 4 coincides with the axis of the connecting pin 3, and the supporting disc 4 is fixedly connected to the end of the connecting pin 3, the inner support rod 5 is installed in the middle of the supporting disc 4, and the axis of the inner support rod 5 coincides with the axis of the supporting disc 4, the ring cutting mechanism 6 is clamped on the supporting disc 4 from one side of the supporting disc 4, the ring cutting mechanism 6 is hinged on the connecting pin 3, and the ring cutting mechanism 6 extends to the surface of the inner support rod 5;

[0026] The circular cutting mechanism 6 includes a support member 61, a support ring 62 and a cutting blade 63. The support member 61 is clamped on the support disc 4 from one side of the support disc 4. The support ring 62 is sleeved on the connecting pin 3, and the support ring 62 is hinged to the support member 61. The cutting blade 63 is hinged to the support member 61, and the edge of the cutting blade 63 extends to the surface of the inner support rod 5. The cutting blade 63 and the support ring 62 are respectively located on the opposite sides of the support disc 4, and the support member 61 is pushed. The support ring 62 rotates along the connecting pin 3, and the cutting blade 63 cuts the wire tube located on the inner support rod 5, thereby realizing the pipe mouth trimming of the wire tube;

[0027] The support member 61 is provided with an air-avoiding groove 7, and the end surface of the support disc 4 facing the support ring 62 is in contact with the inner wall of the air-avoiding groove 7, and the end surface of the support disc 4 facing the cutting blade 63 is an inclined surface, so as to ensure that the support disc 4 has a supporting effect on the support member 61 while the support disc 4 does not interfere with the rotation of the support member 61 along the support ring 62;

[0028] The two ends of the support ring 62 respectively abut against the support plate 2 and the support disc 4 to prevent the support ring 62 from shaking back and forth;

[0029] The support member 61 is fixedly connected with a handle 8 to facilitate the rotation operation of the support member 61 .

[0030] Working principle: First, push the handle 8 to make the support member 61 rotate along the support ring 62, and the cutting blade 63 leaves the inner support rod 5. Since the end face of the support disc 4 facing the cutting blade 63 is a slope, there is enough gap between the slope and the air avoidance groove 7, so that when the support member 61 rotates, there will be no interference with the support disc 4. Secondly, the wire tube to be trimmed is put on the inner support rod 5, and the inner support rod 5 is against the inner wall of the inner metal hose of the wire tube. Then, push the handle 8 to make the support member 61 rotate back, so that the end face of the support disc 4 facing the support ring 62 is against the inner wall of the air avoidance groove 7, thereby supporting and limiting the support member 61. At this time, the cutting blade 63 is against the wire tube. Finally, hold the handle 8 and apply force to one side of the cutting blade 63, then push the handle 8, the support ring 62 rotates along the connecting pin 3, and the cutting blade 63 cuts the wire tube located on the inner support rod 5, thereby realizing the pipe mouth trimming of the wire tube.
