[0012] In a further technical solution, the shape of the driving hole is set to be arc-shaped.

[0013] In a further technical solution, the driving member is arranged in the through hole, and the position of the cutting knife corresponds to the position of the through hole.

[0014] In a further technical solution, the worm gear is arranged between the fixed tube and the support shell.

[0015] In a further technical solution, the shape of the positioning plate is set to be arc-shaped, and the three positioning plates are all arranged in the fixed tube.

[0016] In a further technical solution, the cutting knife is arranged directly above the lower positioning plate.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] For the present utility model, precise and rapid positioning: Place the cable between the three positioning plates in the fixed tube, rotate the turntable to drive the worm, the worm drives the worm gear, and the worm gear makes the sliding rods and the push rods drive the positioning plates to approach each other through the driving holes.

Since the positioning plate 44 is driven by the structure of the worm gear 31 and the worm 21, and the structure of the worm gear 31 and the worm 21 has a self-locking effect, the positioning plate 44 that moves to a suitable position can be stably fixed at this position;

[0033] The positioning assembly 4 includes sliding rods 41. A plurality of sliding rods 41 are all slidably connected inside the driving holes 33. Both ends of the sliding rods 41 are connected to connecting blocks 42. One side of the plurality of corresponding connecting blocks 42 close to each other is connected to a push rod 43.
