The invention discloses a combined mechanical arm mechanical kinetic energy demonstrator and relates to the field of mechanical kinetic energy demonstrators. A traditional kinetic energy demonstratorcannot automatically adjust the height of a free falling body of a test ball, and the test ball cannot be automatically released. The combined mechanical arm mechanical kinetic energy demonstrator comprises a bottom plate, the top of the bottom plate is fixedly connected with a rail, a first hinge block is slidably connected to the outer portion of the rail, two discharging plates are slidably connected to the bottom of the first hinge block, a fixing rod is fixedly connected to the sides, away from each other, of the two discharging plates, a connecting rod is rotatably connected to the firsthinge block, and a connecting plate is fixedly connected to the top of the connecting rod. According to the invention, the height of the free falling body of the small ball can be automatically adjusted, the release of the te
