Experimental device for measuring period of spring oscillator and stiffness coefficient of spring

The utility model provides an experimental device for measuring the period of a spring oscillator and the stiffness coefficient of a spring. The experimental device comprises an experimental device body, wherein the experimental device body comprises a base and a mounting plate; a first supporting rod and a second supporting rod are welded to the base. A top plate is welded to the tops of the first supporting rod and the second supporting rod. A first sliding groove is formed in the first supporting rod. A laser emitting end is arranged in the sliding groove I; a guide rail is arranged on thetop plate; a hanging head is arranged in the guide rail; a spring is mounted on the hanging head; a black cloth cylinder is arranged on one side of the top plate; a second sliding groove is formed inthe second supporting rod. According to the experimental device for measuring the period of the spring oscillator and the stiffness coefficient of the spring, swinging of the spring and the ball bodyis detected through the las
