Abstract
The utility model relates to an electronic pointer, and especially relates to the electronic pointer which can adjust the projection area. The electronic pointer is composed of a pointer body and a focus adjusting part, wherein the pointer body includes a housing and a laser emitter, and the focus adjusting part includes a lens, a lens cap, a lens cylinder, and a rotating thread. The laser emitter is arranged in the housing, and is connected with a power supply via a lead. The pointer body is connected with the focus adjusting part via the thread. The electronic pointer has the advantages of simple structure, easy use, low cost, and the like.
Description
Technical field
The utility model relates to a kind of electronic teacher pointer, the particularly a kind of electronic teacher pointer that can regulate projected area.
Background technology
At present, People more and more is many utilizes media device and projection screen to impart knowledge to students or demonstrate, and explanation person often need indicate by some instruments and demonstrate or focal points; Adopt electronic teacher pointer to demonstrate now mostly; Electronic teacher pointer on the market can satisfy the demands in less environment now, if but explanation person is far away with screen distance, or screen is bigger; Often bring misregister; Indicating effect is relatively poor, the present invention is directed to above problem and improves, and a kind of electronic teacher pointer that satisfies the demands at the various teaching environment is provided.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use to the deficiency of prior art, can satisfy the electronic teacher pointer of various teaching environment.
The utility model solves the technical scheme that its technical matters adopted: a kind of electronic teacher pointer, comprise whip body and focus adjustment part, and wherein the whip body comprises shell and generating laser, focus adjustment partly comprises lens barrel, mobile lens, rotary threaded, mirror cap; Generating laser is built in whip body rear side, is connected with built-in power through lead, and whip body front end is provided with fixed lens, and focus adjustment partly is connected with whip body front end through rotary threaded; The mirror cap links to each other with mobile lens, and mobile lens is fixed on the lens barrel; Case surface is provided with charging socket, lever and switch, and the socket that wherein charges is positioned at whip body below, can be connected with the USB socket through lead, also can directly be connected with outlet; Lever becomes concave arc shape.
The utility model can solve the teaching demonstration of different distance, and the indicating effect problem of unstable can satisfy the teaching demonstration of varying environment.
Description of drawings
Fig. 1 is the structural drawing of the utility model
Among the figure: 1 charging socket, 2 battery cases, 3 laser generators, 4 fixed lenss, 5 rotary threaded, 6 lens barrels, 7 mirror caps, 8 mobile lens, 9 levers, 10 shells, 11 switches
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description.
In accompanying drawing 1, mirror cap (7) is threaded with lens barrel (6), and is positioned at mobile lens (8) the place ahead; Mobile lens (8) is fixed in lens barrel (6) the place ahead, and lens barrel (6) is connected with the whip body through rotary threaded (5), can be through the distance of rotation adjusting and fixed lens (4); Fixed lens (4) is built in whip body the place ahead, lens barrel (6), and mobile lens (8) and rotary threaded (5) constitute the focus adjustment part; Regulate the distance of fixed lens (4) and mobile lens (8), the area of scalable laser projections in screen; In the built-in whip body of generating laser (3); Through lead and battery case (2), external switch (11) connects, and external switch (11) is directly controlled the interruption of power supply; Battery case (2) can be put rechargeable battery; Battery case (2) is connected with charging socket (1) through lead, and charging socket (1) can be connected with USB interface through lead, also can directly connect other interfaces.
The principle of work of present technique: open external switch (11), generating laser (3) produces laser, and laser is through fixed lens (4); Lens barrel (6); Mobile lens (8) projects in the screen, through rotary threaded (5), regulates the distance of fixed lens (4) and mobile lens (8); Distance between fixed lens (4) and the mobile lens (8) has determined can regulate according to actual conditions with the equidistant area of laser projections in screen down.
