Circuit for detecting reaction force and working machine

The utility model relates to the technical field of operation machinery control, and provides a circuit for detecting reactive force and an operation machinery, the circuit comprises a detection assembly connected with a first end of a hydraulic loop, an operation assembly connected with a second end of the hydraulic loop, and a control assembly; the detection assembly is connected with the control assembly; the operation assembly is connected with the control assembly; the operating assembly includes: a working force generating structure; the detection assembly detects a pressure signal of the hydraulic loop; the control assembly converts the pressure signal into an electric signal; the working force generating structure receives the electric signal and generates working force. The device is used for overcoming the defects of low operation efficiency and damage to the operation machinery caused by the fact that the operation machinery still keeps the current state when encountering unovercome external force
