Problems solved by technology

The main purpose is to improve the types of patterns projected by laser pens, not for actual slides or PPT presentations. Laser pens and laser pens in the prior art still generally have the disadvantage that they can only indicate but not mark

Abstract

The invention discloses a laser pen for distance education. The laser pen comprises a cuboid laser pen shell and four laser projection subareas arranged on the four sides of the cuboid. A laser lightsource, a micro stepping motor, a pair of shading ruler strip reels, a pair of shading ruler strip clamping grooves and a pair of shading ruler strips are arranged in each laser projection subarea, and a laser light projection area is formed by the pair of shading ruler strip clamping grooves through a gap between two free ends; and the four laser projection subareas are combined and adjusted to form a projection mark with a specified shape on the projection screen. Aiming at public projection of slides or PPT, an operator is accurately marked, and an operation space of specific projection content is selected; the operation is simple, and the marking function during the slide speech can be realized; the laser pen is simple and compact in structure and convenient to manufacture.

Description

technical field [0001] The invention discloses a laser pointer for distance education, which belongs to teaching aids, and the specific technology relates to the technical field of lasers (H01S 3 / 00). Background technique [0002] As auxiliary tools for projectors, laser pointers and laser pointers are very suitable for use in environments such as PPT presentations and classroom teaching in large open spaces. With the development of Internet technology, distance education is becoming more and more popular. A common way of distance education is to use slides or projectors to explain courseware in the classroom, and then carry out distance education training through video or live video. In this scenario, the laser pointer in the prior art is usually just a laser spot, and the clarity, accuracy, and eye-catching degree of the mark are difficult to meet the basic needs of distance education video recording. [0003] In the existing technology, there are some existing technologi...
