The positioning part 3 can realize the positioning of the end of the wire to ensure the accuracy of the outlet position.

[0020] Among them, the wire-dividing mechanism 2 includes: a roller 201, the outer wall of the roller 201 is equidistantly equipped with several groups of wire-dividing seats 202, and the number of each group of wire-dividing seats 202 is two, which are slidably and symmetrically arranged on the outer wall of the roller 201, and the two wire-dividing seats 202 are both conical in shape, so that the wires can be limited between them. The outer wall of the roller 201 is installed with a separator 203, and the separator 203 is located between the two wire-dividing seats 202. The separator 203 is spirally arranged, which divides the outer wall path of the roller 201 into paths to ensure that the wires can be smoothly wound around and will not be entangled with each other. The inner cavity of the roller 201 is equidistantly opened with several drive cavities 204 corresponding to the wire-dividing seats 202, and the inner cavity of the drive cavity 204 is equipped with a drive unit that drives the two wire-dividing seats 202 to move closer or farther away synchronously.

[0021] The driving part includes: a lead screw 206, the threads on the left and right sides of the outer wall of the lead screw 206 are positive and negative threads, the lead screw 206 is rotatably installed in the inner cavity of the driving cavity 204, the outer wall of the roller 201 is symmetrically provided with a limit groove 205, the outer wall of the lead screw 206 is symmetrically screwed with two moving seats 207, when the lead screw 206 rotates, the two moving seats 207 can be moved closer or farther away from each other, the outer wall of the moving seat 207 passes through the inner cavity of the limit groove 205 and is connected to the inner wall of the branching seat 202, the limit groove 205 can move the moving seat 207 The inner cavity of the roller 201 is rotatably mounted with one end of a rotating rod 208, and the other end of the rotating rod 208 passes through the outer wall of the roller 201. The outer wall of the rotating rod 208 is interference-fitted with a first bevel gear 209 to ensure that the two can rotate together. A second bevel gear 2010 is fixedly mounted on one section of the lead screw 206, and the second bevel gear 2010 is meshed with the first bevel gear 209. When the first bevel gear 209 rotates, the second bevel gear 2010 can rotate synchronously.

[0022] In addition, the positioning part 3 includes a mounting frame 31 and positioning holes 32, wherein there are several positioning holes 32, which are equidistantly opened on the outer wall of the mounting frame 31 and correspond to the positions of several branching mechanisms 2.

[0023] As a preferred solution, further, a reducer 4 is installed on the outer wall of the base 1, and the output end of the reducer 4 is connected to the roller 201.

[0025] When in use, a single wire is passed through the positioning hole 32 on the rear side, wrapped around the outer wall of the roller 201, and limited by the two branching seats 202. The cable is wrapped around for a circle and divided and limited by the separator 203, and finally passed through the positioning hole 32 on the front side to complete the branching operation. The wire can then be pulled by a traction machine, or the roller 201 is driven by the reducer 4 to rotate to assist in the outlet of the wire. When it is necessary to adjust the limiting space of a certain wire, the rotating rod 208 at that position is rotated to make the first bevel gear 209 rotate synchronously and drive the second bevel gear 2010 to rotate, thereby rotating the lead screw 206, and then the two movable seats 207 are respectively moved closer to or away from each other, so that the two branching seats 202 are moved closer to or away from each other, and the width that can accommodate the wires is adjusted to adapt to wires of different thicknesses.
