The invention provides a fork neutral position switch triggering safety torque disconnection circuit. The fork neutral position switch triggering safety torque disconnection circuit comprises a signal interlocking circuit and a triggering safety torque disconnection circuit. The signal interlocking circuit is used for receiving an upper computer task signal T1, a standby signal T2, a lifting enable signal E1 and a walking enable signal E2 which are sent by the controller, and generating a neutral position protection signal P1 and a pallet fork enable signal E3; a meso-position protection signal P1 is sent to a trigger safety torque disconnection circuit, and a fork enable signal E3 is sent to a controller; the safety torque disconnection triggering circuit is used for monitoring fork neutral position switch signals and receiving neutral position protection signals P1, and the fork neutral position switch signals are two paths of OSSD signals; and when the median protection signal P1 is at a high level, and any one of the two paths of OSSD signals is at a low level or both the two paths of OSSD signals are at a low level, the safety torque disconnection circuit is triggered to output a high-level safety torque disconnection signal STO. According to the invention, the operation reliability of the stacking machine is improved.
