Abstract
The utility model discloses a laser pointer, which comprises a lens, a hollow pen holder and a pen cap which are sequentially screwed into a whole, wherein a laser module is arranged in the inner cavity of the pen holder, and a switch for connecting or disconnecting the power supply circuit of the laser module is arranged on the pen holder; a first reflector and a second reflector which are sloped against the axis of the lens, and the first reflector is arranged opposite the second reflector; the second reflector is positioned below the first reflector, and the first reflector is fixed on the inner wall of the lens; and the second reflector is fixed on the inner wall of the lens by a spring, and the output laser of the laser module is reflected by the first reflector and the second reflector and then is output from the front of the lens. The lens is additionally arranged at the output end of the laser pointer, and when the laser pointer is shaken, the second reflector vibrates under the action of the spring; therefore, the laser beams output by reflection can produce circles, waves and other irregular patterns to enrich the output effect of the laser beams.
Description
Technical field
The utility model relates to a kind of laser stylus.
Background technology
Laser pen so be commonly used for indication usefulness, can replace marking toolses such as teacher's pointer owing to can see hot spot over tens meters, also can use when playing lantern slides ppt.Yet the green laser stylus of existing tradition has only the light beam of a kind of indicative function usually, and pattern dullness, function singleness can't satisfy people's multiple demand.
The utility model content
Technical problem to be solved in the utility model is the problem that solves laser stylus pattern dullness, function singleness.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of laser stylus, comprise that spinning is the camera lens of one successively, the hollow penholder and the cap for brush, be provided with the laser module in the inner chamber of penholder, penholder is provided with the switch that is used to be switched on or switched off laser module current supply circuit, be provided with successively from front to back in the inner chamber of described camera lens and first of camera lens axis tilt setting, second reflective mirror, described first, second reflective mirror is oppositely arranged and second reflective mirror is positioned at the below of first reflective mirror, first reflective mirror and camera lens inwall are fixed, second reflective mirror is fixed through spring and camera lens inwall, and the output laser of laser module is through first, second reflective mirror reflection back is from the anterior output of camera lens.
On the basis of such scheme, the angle of described first, second reflective mirror and camera lens axis is 15 degree～75 degree.
The utility model, output terminal at the laser stylus has increased a camera lens, be provided with first, second reflective mirror that is oppositely arranged in the inner chamber of camera lens, first reflective mirror and camera lens inwall are fixed, second reflective mirror is fixed through spring and camera lens inwall, the output laser of laser module is exported from camera lens is anterior after first, second reflective mirror reflection, when rocking the laser stylus, second reflective mirror produces vibration under the effect of spring, therefore, laser beam through reflection output can produce irregular patterns such as circle, wave, has enriched the output effect of laser beam.

Fig. 2 is the utility model camera lens structure for amplifying synoptic diagram and laser-bounce output light path synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1 and Figure 2, the utility model comprises that spinning is camera lens 1, hollow penholder 2 and the cap for brush 3 of one successively, be provided with laser module 4 in the inner chamber of penholder 2, the outside surface of the cap for brush 3 is provided with elastic pen clips 7, battery 5 is housed in the cap for brush 3, the power supply input positive terminal of the positive pole of battery 5 and laser module 4 offsets, the negative pole of battery 5 is communicated with the formation current supply circuit by the metal cap for brush and penholder with the power cathode of laser module 4, penholder 2 is provided with the switch 6 that is used to be switched on or switched off laser module current supply circuit.
Camera lens 1 in a tubular form, be provided with first, second reflective mirror 11,12 that is oppositely arranged in its inner chamber, first, second reflective mirror be parallel to each other and with the angle of camera lens axis be 15 degree～75 degree, preferred 30 degree～60 degree, first reflective mirror 11 is fixed with the inwall of camera lens 1, second reflective mirror 12 is fixed and second reflective mirror 12 is positioned at the below of first reflective mirror 11 through the spring 13 and the inwall of camera lens 1, from the front portion output of camera lens 1, the front portion of camera lens 1 is provided with and is used for dustproof transparent plastic sheet 14 outgoing laser beam of laser module 4 after first, second reflective mirror 11,12 reflections.
The utility model utilizes one group of catoptron that two secondary reflections are taken place laser optical path, its light path is offset by former direction, wherein a slice catoptron is fixed on the inwall of camera lens through spring, utilize the vibrations of spring to make reflective mirror produce vibration, like this, laser beam through another sheet mirror reflects output can produce irregular patterns such as circle, wave, has increased the rich and vividness of laser beam output pattern.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
