Abstract

The invention relates to a teaching laser rod, which comprises a columnar laser rod body. The teaching laser rod is characterized in that the end, opposite to a laser head, of the columnar laser rod body is provided with a USB interface; the middle portion of the tail end of the USB interface is fixedly provided with a sleeve; the sleeve sleeves a reciprocating screw rod; and the reciprocating screw rod is driven by a stepping motor to facilitate the sleeve to reciprocate on the reciprocating screw rod. The columnar laser rod body is internally provided with a circuit board and a battery for providing power for the circuit board. The circuit board comprises an MCU. The MCU is connected with a laser generation module, a stepping motor driving module, a storage module, a wireless communication module and a key circuit. The USB interface is connected with the MCU. The wireless communication module is used for receiving audio signals of a hand-held terminal. The teaching laser rod can realize interaction of the teaching laser rod and the hand-held terminal.

Description

technical field [0001] The invention relates to the technical field of electronic teaching appliances, in particular to a teaching laser rod. 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 purpose of the present invention is to provide a teaching laser bar, 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 teaching laser rod, including a columnar laser rod body, characterized in that: the opposite end of the laser head of the columnar laser rod body is provided with a USB interface, and a sleeve is fixedly arranged in the middle of the end of the USB interface , the sleeve is sleeved on a reciprocating screw rod, and the reciproca...
