Accurate controllable interactive demonstration seismograph

An accurate controllable interactive demonstration seismograph relates to the technical field of earthquake monitoring. The accurate controllable interactive demonstration seismograph is characterized by comprising the components of a seismograph model, a cover, loong models, toad models, a base, a ball screw, a collecting module, a backbone insulation protective cover, a flange, a motor, pipes, an upper limit switch, a lower limit switch, a strong magnet, an electromagnet, a programmable control board and a pressure sensor. The accurate controllable interactive demonstration seismograph has advantages of simple structure, automatic control for steel ball placing positions, convenient use, high reliability and no easy damage.
