The invention discloses an auxiliary device used for multimedia teaching, and relates to the technical field of teaching appliances. The device comprises a handle, a pointer body is connected to one end of the handle, a battery is mounted in the handle, the battery is electrically connected with a button switch, the battery and the button switch are electrically connected with the input end of a voltage transformation device, the button switch is mounted on the outer surface of the handle, the voltage transformation device is mounted in the handle, the pointer body comprises a rubber sleeve, conducting plates and an electrorheological fluid filling layer, the rubber sleeve wraps the electrorheological fluid filling layer in a sealing manner, the two conducting plates are fixedly connectedto two sides of the inner cavity of the rubber sleeve, and one sides, far away from the rubber sleeve, of the two conducting plates are electrically connected with and attach to two sides of the electrorheological fluid filling layer. When the auxiliary device is not in use, the electrorheological fluid filling layer is in the liquid state, the pointer body is soft, then the pointer body winds thecorrugated surface of the handle, meanwhile, the tail end of the pointer body is inserted in a limiting hole for fixing, so that the length of a pointer used for teaching is greatly shortened, and the portable storage and carrying by a user are facilitated.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an auxiliary equipment for multimedia teaching. Background technique [0002] In the classroom teaching of colleges and universities, PPT teaching plans are usually used together with blackboard writing for teaching, and PPT teaching plans are the most of the teaching content. Whip to give instructions and cooperate with auxiliary teaching. However, most of the existing teaching whips use a straight whip or a telescopic whip. Compared with the straight whip, the length of the telescopic whip is reduced after storage. However, the last section of the telescopic whip needs to store all the previous sections, and its length is still relatively long. Put it in a bag or hold it in your hand, it is inconvenient to carry it with you, and if the length of the last section is short, more sections must be needed to make up for the stretched length, which is easy to damage durin...
