Teaching device for computer information technology

Abstract

The invention belongs to the field of teaching devices, and particularly relates to a teaching device for a computer information technology. A scheme is put forward and aims at the existing problems that more often than not, a connection wire between a microphone and a horn of a loudspeaker is wound directly on the horn when not in use, winding can be easily caused, and therefore using inconvenience is brought. According to the scheme, the teaching device comprises a device body; the device body is of a hollow structure; a first rotating shaft is movably arranged in the device body; a first gear and a winding disc sleeve the first rotating shaft; the first gear is located on one side of the winding disc; the winding disc is connected with a wire; and the top end of the device body is provided with a first through hole, and the wire extends out of the device body through the first through hole. The teaching device for the computer information technology is reasonable in structure, low in production cost, and capable of accommodating wires, avoiding wire winding, effectively stretching and retracting, and reducing the volume of the device body and convenient to carry, and meets use requirements.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to a teaching device for computer information technology.
