Cathode-ray magnetic tracking response speed training device

The invention discloses a cathode-ray magnetic tracking response speed training device. A cathode-ray tube is fixed on a platform through a bracket; a cathode ray is in a horizontal state; an upper permanent magnet is located above the cathode-ray tube; an upper sliding pair is arranged above the cathode-ray tube; a static part of the upper sliding pair is connected to the platform through the bracket; the upper permanent magnet and a sliding part of the upper sliding pair are connected into a whole; the sliding direction of the sliding part of the upper sliding pair is the vertical direction; the sliding part of the upper sliding pair is hinged with a connecting rod; the connecting rod is hinged with a crank; the crank is connected to a drive mechanism; a lower permanent magnet is located below the cathode-ray tube; a lower sliding pair is arranged below the cathode-ray tube; the static part of the lower sliding pair is connected to the platform through the bracket; the lower permanent magnet and the sliding part of the lower sliding pair are connected into a whole; the sliding direction of the sliding part of the lower sliding pair is the vertical direction; the sliding part of the lower sliding pair is connected with a handle; and the upper permanent magnet and the lower permanent magnet are opposite in like poles and are aligned in the vertical direction.
