Disclosed is a protection system for wire breakage of a reciprocating electric push rod. The circuit comprises a resistor R2 in a control circuit. One end of the resistor R2 is connected with a pin 2of the PC817 optocoupler P1; grounding of the other end, the PC817 optocoupler is connected with the base electrode of the triode C1 through a resistor R1; the output end of the triode C1 is connectedwith the coil input end of the relay U1; a coil of the relay U1 is reversely connected with the relay U1; the relay U1 comprises two common COMs (Component Object Model); one end of each of two common COMs is connected with a 24V power supply, and the other end is connected with GND; a pin 2 and a pin 5 of the relay U1 are connected together, and a pin 4 and a pin 7 of the relay U1 are connectedtogether; a pin of the relay 5 is connected in series with a resistor R5; wherein the resistor R4 and the resistor R5 are connected in parallel, one end of the resistor R4 is connected with the optocoupler P2 and the optocouple
