Summary:The invention discloses a lever principle experiment device for physics experiment, including a framework. A guide rail is fixedly installed inside the bottom end of the frame. A support seat is arrange on that guide rail. A lever is arranged at that top end of the support. A pressure bar is arranged above the lever on the right side of the support, a fixing bracket is fixedly installed on the upper end surface of the frame on the right side of the pressure bar, the fixing bracket is vertically arranged, a motor is fixedly installed on the left side of the top end of the fixing bracket, a sliding sleeve is arranged on the outer sleeve of the pressure bar, and an avoidance hole is arranged on the outer frame of the sliding sleeve. The lever principle experiment device used in physics experiment facilitates teachers' demonstration through the cooperation of multiple clever mechanisms, and improves students' understanding effect through the built-in pressure display mechanism, which is conducive to the populariz
