Description
Technical field
This utility model belongs to teacher's pointer technical field, more particularly, to a kind of multifunction laser teacher's pointer with USB flash disk.
Background technology
It is 633 gas lasers that the laser pen of early stage uses wavelength, is generally used for producing the laser beam that energy is less than 1mW.
Generally the least expensive laser pen uses wavelength close to the deep red laser diode of 670/650nm.Slightly expensive is then 635nm using wavelength
Red-orange diode, this wavelength is easier to be identified by human eye.Also there is the laser pen of other colors, be most commonly that ripple
The green glow of a length of 532nm.Recent years, the Huang-orange laser pen of 593.5nm also begins to be occurred.In September, 2005 occurs in that 473nm
Blue laser pen." blue violet light " laser pen that wavelength is 405nm is occurred in that at the beginning of 2010.Laser pen irradiates the apparent of luminous point
Brightness not only depends on power and the surface reflectivity of laser, additionally depends on the colour vision of human eye.For example, because human eye is to visible ray
The green glow of the spectrum a length of 520-570nm of medium wave is most sensitive, and redder or more blue wavelength sensitivity is declined, so under equal-wattage
Green glow seems brighter than other colors.
Existing multifunction laser teacher's pointer exists and lacks USB flash disk store function it is impossible to stretch, the short problem of service life.
Therefore, invent a kind of multifunction laser teacher's pointer with USB flash disk and seem very necessary.
Utility model content

Multifunction laser teacher's pointer with USB flash disk, including laser lamp, whip head, the first expansion link, the second expansion link, whip body, button, slot,
Rear cover structure, adjusts button, charge port, battery and female thread, described laser lamp is arranged on the top of whip head；Described regulation
Button is separately positioned on the first expansion link and the junction point of the second expansion link；Described charge port is arranged on the right side of battery；Institute
The button stated is arranged on the upper right quarter of whip body；Described slot is by being internally threaded to the top of rear cover structure；After described
Lid structure includes USB plug, external screw thread, screw hole, lid, draw-in groove and lid, and described USB plug is arranged on externally threaded
Portion；Described screw hole is arranged on the top of lid；Described draw-in groove is arranged on the centre position of lid.
This utility model can also adopt following technical measures.
Described laser lamp specifically adopt infrared laser lamp, be conducive to use when conveniently point to accurate position so that
Easy to use.
The stainless steel tube of a diameter of 1cm to 2cm specifically adopted by the first described expansion link and the second expansion link, desirably prevents
Corrosion, reduces maintenance cost.
Described battery specifically adopts rechargeable lithium battary, is conducive to without often changing battery, charge efficiency is fast.
Described button specifically adopt PVC plastic self-locking pacify button, desirably prevent the pushing time be positioned on numb above, reduce
The injury of opponent.
Compared with prior art, this utility model has the advantages that：
This utility model has the advantages and positive effects that：The setting by rear cover structure for this utility model, is conducive to
