Abstract
The invention relates to a laser electronic pointer. The laser electronic pointer comprises a pen holder, laser heads, an adjuster and a switch, wherein a pen point at the front end of the pen holder is provided with the two laser heads, the pen point can be separated or combined through the adjuster on the pen holder, and the two laser heads are projected jointly to be one dot shape or projected separately to be two dot shapes. The changing range of a separable angle of the pen point is within 0-150 degrees. The pen point and the pen holder are movably connected and can be detached to be updated. Through the improvement of the laser electronic pointer, a common laser pointer can have the two emitting points, and therefore one straight line can be determined in a two-point mode in teaching activities, and the teaching contents are favorable for being indicated.
Description
Technical field
The invention belongs to the realia field, relate in particular to a kind of laser-electronic ferule.
Background technology
Teacher's pointer is teacher's teaching-guiding apparatus, and along with the arrival of multimedia era, along with the reach of science, teacher's pointer also updates, and laser pointer is arisen at the historic moment.Laser pointer is that less radio-frequency page turning laser pen uses computing machine USB technology, radiotelegraphy, integrates remote-control computer function and laser pointer, is coordinating the computer-projector instrument but the product demonstration of use, the ideal tools of electronic teaching.But common laser-electronic ferule, only have a laser head, can only determine a bit in the time of use, when needs are determined the straight line scope, can only pass through move mode, laser projection point is slided on background cloth.But this can not play clear and definite indicative function.How to improve laser pen, make it can indicating range clearer and more definite, being one be worth the problem solved.
Summary of the invention
The present invention only has a laser head in order to solve the common laser electronic teacher pointer, can only determine a point, and can't indicate the teaching inconvenience that clearer and more definite scope causes, and a kind of laser-electronic ferule is provided, bag penholder, laser head, regulator, switch.The nib of penholder front end has two laser heads, by penholder adjusted device, can nib can separate or merge, and two laser heads are merged and are projected as a point-like or separately are projected as two point-like.
Further technological improvement of the present invention is, the separable angle variation range of the nib of laser-electronic ferule is 0 ~ 170 degree.In teaching process, when using two points, nib is closed up, and angle is 0 while spending, and two laser heads project a point; Determine the content on straight line when needs and can adjust the angle that nib is separated, determine the length of straight line, 180 degree are critical value, and when surpassing 180, two laser heads point to not in one plane.Therefore the separable angle variation range of nib of laser-electronic ferule is set to 0 ~ 170 degree, comparatively suitable.The present invention is designed to 0 ~ 150 degree in order to reach ideal effect by the separable angle variation range of nib.
The further technological improvement of invention is, between the nib of laser-electronic ferule and penholder, for being flexibly connected, can dismantle and be upgraded.When laser head is used aging or breaks down, can upgrade separately nib, cost-saving.
The beneficial effect that the present invention obtains:
The present invention is by the improvement that the common laser electronic teacher pointer is carried out, and cost increases not obvious, makes laser pen have two laser heads, not only can to have merged projection be a luminous point but also can separate by regulator, projection is two luminous points, and then definite straight line, more is conducive to teaching-guiding.
The accompanying drawing explanation
Fig. 1 is laser-electronic ferule overall schematic of the present invention;
Fig. 2 is that laser-electronic ferule of the present invention is used schematic diagram.
Embodiment
Understand and implement the present invention for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.
The invention discloses a kind of design proposal of USB economize on electricity keyboard, Fig. 1 is USB economize on electricity keyboard perspective diagram, comprises keyboard 1, accumulator 2.While connecting mobile device, when mobile device has external power supply, accumulator 2 automatic chargings, when mobile device during without external power supply, self battery undersupply, accumulator 2 is mobile power supply equipment automatically; The accumulator 2 of keyboard 1 can lead to the usb data line and directly connect the external power source charging.Accumulator 2 term of life arrive, and accumulator 2 can be changed.Have LED lamp 3 on keyboard 1, when the mobile device power shortage, keyboard 1 is mobile power supply equipment automatically, starts LED lamp 3, with the prompting user.Keyboard 1 has Shock inductor, when keyboard 1 has slight vibrations, starts keyboard 1 duty.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
