The driving roller 5 drives the driven roller 7 to start rotating synchronously through the gear transmission group 6. Then, pass the wire to be processed through the groove structure between the driving roller 5 and the driven roller 7 from left to right. Subsequently, cooperate with the groove structure by the driving roller 5 and the driven roller 7 to start extruding and pulling the wire. Then, the wire passes through the right end of the top shell 2.

When the driving roller 5 rotates, drive the driven roller 7 to rotate in the opposite direction synchronously with the driving roller 5 through the gear transmission group 6, thereby improving the synchronous speed of the driving roller 5 and the driven roller 7 during rotation.

[0035] 2. The present invention is provided with a first fixed pulley 8, a second fixed pulley 10 and a movable pulley 11.
