The invention provides a multifunctional electronic pointer for teaching. The technical problem that in the prior art, an electronic pointer has a single function and is not high in practicability issolved, a plurality of laser pens capable of emitting different patterns are arranged on the outer wall of a shell I, a sliding groove I, a sliding groove II and a third sliding groove III are formedin the outer circumferential face of the shell I, an installing frame which can slide in a cavity inside the shell I is arranged inside the shell I, a groove I is formed in the installing frame, a user can press the laser pens into the groove I from the sliding groove III, limiting rods are arranged at the top ends of the laser pens, the limiting rods can slide inside the sliding groove II and arefinally clamped into the sliding groove I, matched electrodes are arranged on the laser pens and the groove I, after the laser pens enter the groove I, circuits of the laser pens, laser pen switchesand batteries are closed, and the laser pens can be controlled to emit different patterns on a blackboard by pressing the laser pen switches.
Description
technical field [0001] The invention belongs to the technical field of teaching application, and in particular relates to a multifunctional electronic pointer for teaching. Background technique [0002] With the development of science and technology, the teaching method of multimedia has gradually replaced the previous teaching method of chalk and blackboard, wherein the multimedia equipment includes the electronic pointer remote control pen. The electronic pointer remote control pens currently on the market are mainly used for teaching courseware instructions and page-turning explanations. Their functions are single, and there are still some deficiencies. In order to control multiple multimedia devices, it needs to have a storage function. Generally speaking, the electronic pointer in the prior art has a single function and is not practical. Moreover, the emitting head of the existing laser pointer can only emit a pattern , in multimedia teaching, if it is necessary to ind...
