The invention discloses a cable deflection preventing type drawing machine. The drawing machine comprises a base, rollers, a displacement sensor, a protective cover and an anti-deflection guide wheel. The rollers are mounted at the bottom end of the base through first fixing rotary shafts, a driving motor is mounted at the top end of a turnable case, the displacement sensor is mounted on one side of the driving motor, and the protective cover is mounted at one end of the top of the turnable case through a second fixing rotary shaft. The anti-deflection guide wheel is mounted on one side of a traction disk, an alarm is mounted on one side of a driving motor switch, a PLC (programmable logic controller) is mounted on one side of the alarm, and a footboard is mounted under a console. The cable deflection preventing type drawing machine has advantages that by the anti-deflection guide wheel, cable deflection can be effectively prevented while the cable drawing machine is convenient to move, an operator can be well protected, potential safety hazards are reduced, real-time monitoring of the driving motor is realized, and the equipment failure rate is decreased.
