Abstract

The invention relates to a teaching laser rod with a telescopic laser head, which includes a cylindrical laser rod body and is characterized in that the cylindrical laser rod body is provided with the laser head capable of being telescopic back and forth; the end of the laser head is provided with a sleeve on a reciprocating screw; the reciprocating screw is further driven by a stepping motor so as to facilitate a reciprocating action of the sleeve on the reciprocating screw, and the laser head is driven to be telescopic; a circuit board and a battery supplying power for the circuit board are also arranged in the cylindrical laser rod body; and the circuit board includes an MCU which is connected to the laser head through a laser driving circuit. The teaching laser rod with the telescopic laser head can realize the interaction of the teaching laser rod and a hand-held terminal.

Description

technical field [0001] The invention relates to the technical field of electronic teaching appliances, in particular to a retractable teaching laser rod with a laser head. Background technique [0002] Laser sticks are an essential tool for existing multimedia teaching. However, the existing laser sticks are only used for laser positioning. Storage, portability and recreation of teacher data. Contents of the invention [0003] In view of this, the object of the present invention is to provide a teaching laser bar with a retractable laser head, which can realize the dancing of the teaching laser bar controlled by a handheld terminal. [0004] The present invention adopts the following scheme to realize: a laser head retractable laser rod for teaching, including a columnar laser rod body, characterized in that: the columnar laser rod body is provided with a laser head that can be stretched back and forth, and the end of the laser head is set There is a sleeve, and the slee...
