Lever device for physical mechanics experiment

The utility model relates to the technical field of lever experiment devices, and discloses a lever device for physical mechanics experiments, which comprises a bottom plate, side plates are rotatably mounted on the left side and the right side of the top of the bottom plate, a top cover is inserted outside one end, far away from the bottom plate, of each side plate, and a handle is arranged at the top of each top cover. A lever adjusting mechanism is arranged at the top of the bottom plate, and a storage mechanism is arranged in the top cover. According to the lever device for the physical mechanics experiment, through the arranged lever adjusting mechanism, in the using process, an adjusting button is rotated, so that the adjusting button controls an upper lever to slide through a threaded rod, the upper lever is separated from a fulcrum shaft, and at the moment, the distance between a lower lever and the upper lever is increased; the lower lever and the upper lever can move outside the fulcrum shaft to adj
