Abstract

The invention relates to an intelligent teaching aid device for English teaching. The intelligent teaching aid device for English teaching comprises an operating pen mechanism, a clamping head mechanism, an electric telescopic rod mechanism, a blackboard eraser mechanism, a metal tube and a movable cover. The intelligent teaching aid device for English teaching is characterized in that the clamping head mechanism is installed at the lower end of the operating pen mechanism, the electric telescopic rod mechanism is installed at the other end of the operating pen mechanism, the blackboard erasermechanism is installed at the upper end of the electric telescopic rod mechanism, the movable cover is installed at the upper end of the blackboard eraser mechanism, and the metal tube is arranged inthe middle of the upper end of the movable cover. According to the intelligent teaching aid device for English teaching, the clamping head mechanism is arranged, and can be turned on and turned off by using a rotating shaft to clamp a chalk; when the clamping head mechanism is broken off, a return spring in the rotating shaft is deformed under the action of an external force, the chalk is put into the clamping head mechanism and then the hand is released; and the return spring loses the external force, so that the rotating shaft is driven to reset, and the clamping head mechanism can stably clamp the chalk, and teachers are not required to be in direct contact with the chalk, so that harm to the body is avoided.
