[0032] In this embodiment, after the tenth gear 807 is driven to rotate, the meshing relationship between the above gears and the transmission ratio are matched, so that the worm 7 can be driven to rotate at a faster speed, thereby ensuring the speed of cable straightening.

[0033] The tenth gear 807 is connected to a reciprocating mechanism 9, which includes a rack 901 meshingly connected to the tenth gear 807, one end of the rack 901 is slidably connected to a guide slide rod 902 arranged on the top of the straightening table 1, the other end of the rack 901 is hingedly connected to a seventh connecting rod 903, the other end of the seventh connecting rod 903 is hingedly connected to an eighth connecting rod 904, and the other end of the eighth connecting rod 904 is fixedly connected to the output end of the servo motor 905.

[0034] In this embodiment, after the servo motor 905 is started, it cooperates with the seventh connecting rod 903 and the eighth connecting rod 904 to pull the rack 901 to slide back and forth on the guide slide rod 902, thereby driving the tenth gear 807 to rotate back and forth, and allowing the two straightening wheels to rotate back and forth synchronously in opposite directions, so that the cable can be repeatedly straightened to improve the straightening effect.
