Abstract
The invention relates to a combined laser demonstrator. The demonstrator comprises a pen body. A lower end of the pen body is provided with a square groove. A USB joint is installed in the square groove. An upper end of the pen body is provided with a telescopic pointer and a laser emitter. An upper portion of the pen body is provided with a laser emission button. A middle portion of the pen body is provided with an upward button and a downward button. The telescopic pointer is located at a left side of the laser emitter. The pen body with the telescopic pointer is arranged, which is good for usage of the laser demonstrator when an electric quantity of a cell is not enough; the square groove is arranged, which is good for storage of the USB joint and space saving; and the structure is simple, and operation is convenient, economical and practical.
Description
Technical field
The present invention relates to teaching aid design field, particularly relate to a kind of combined laser demonstration device.
Background technology
Writing on the blackboard, the rod of picture is indicated when what traditional teacher's pointer was is teachers；Old times teacher is used for body
Penalizing and urge on the instrument being similar to ruler of student, modern society imparts knowledge to students, particularly academy's work
In the most electronic teacher pointer replace.Teacher's pointer overall length 49.3 centimetres, on 12.5 to 15.5 lis of handle
The Dens Elephatis block that long 3 centimeter length 0.7 centimetre is wide it is inlaid with at meter.At present, remote-control laser pen uses and calculates
Machine USB technology, radio-frequency technique, integrate remote-control computer function and laser pointer, be to cooperate with PC
Machine or laptop computer, combine projector use and be widely used in product demonstration, electronic teaching and Symposium Held
The preferable demonstration instrument of the occasions such as view.Laser as a kind of new type light source, because of have good directionality,
Decay the advantages such as little, visual acuity, is favored in high-end market；Laser pen is laser product market
One product of segmentation, can be applicable to impart knowledge to students, surveys and draws, the many aspects such as amusement；Along with sending out of science
Exhibition, teacher's pointer also updates, and laser pointer is arisen at the historic moment.Laser pointer is less radio-frequency page turning laser
Utilization computer USB technology, radiotechnics, integrate remote-control computer function and laser pointer,
It is to cooperate with PC or laptop computer, combines projector use and be widely used in product demonstration, electronic teaching
And the preferable demonstration instrument of the occasion such as academic conference.Controlled in wireless computer distance is more than 20 meters, in religion
Any one corner of room or meeting room can operating computer flexibly and comfortably.Remote-control laser pen uses
Computer USB technology, radio-frequency technique, integrate remote-control computer function and laser pointer, be to cooperate with
PC or laptop computer, combine projector use and be widely used in product demonstration, electronic teaching and science
The preferable demonstration instrument of the occasions such as meeting.Controlled in wireless computer distance, more than 25 meters, makes you in classroom
Or any one corner of meeting room can manipulate your computer flexibly and comfortably.And on imparting knowledge to students at present
Conventional laser demonstration device only uses in the case of battery has electricity, when battery electric quantity deficiency, and nothing
Method normally uses, it is impossible to meet the demand of practical situation.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of combined laser is drilled
Show device.
The present invention is to be achieved through the following technical solutions:
A kind of combined laser demonstration device, including a body, the lower end of described body is provided with square groove, a body
Upper end flexible teacher's pointer and laser beam emitting head are installed, the top of a body is provided with Laser emission button,
The middle part of body is provided with upwards button and down button.
As the preferred technical solution of the present invention, in described square groove, USB joint is installed.
As the preferred technical solution of the present invention, described flexible teacher's pointer is positioned at the left side of laser beam emitting head.
During onsite application, USB joint is inserted in the USB interface that computer is corresponding by operator, and USB connects
Head connects teacher's pointer and computer by wireless signal, can launch laser by operation Laser emission button,
Can use, it is simple to the content of courses on instruction blackboard or the content of displaying；When battery electric quantity is not enough
Time, and when having little time again charging, can flexible teacher's pointer be elongated to a certain degree from a body, formed
One traditional teacher's pointer, by the content on its front end instruction blackboard, can use.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is flexible by being provided with
A body of teacher's pointer contributes to the use of laser demonstration device when battery electric quantity deficiency, by arranging square groove
Contribute to depositing of USB joint, additionally aid saving space, and simple in construction, easy to operate, warp
Ji practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1 a, body；2, square groove；21, USB joint；3, flexible teacher's pointer；4, laser is sent out
Penetrate head；5, Laser emission button；6, upwards button；7, down button.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, the present invention is further elaborated.Should be appreciated that described herein specifically

Refer to the structural representation that Fig. 1, Fig. 1 are the present invention.
Described a kind of combined laser demonstration device, including a body 1, the lower end of described body 1 is provided with square
Groove 2, the upper end of a body 1 is provided with flexible teacher's pointer 3 and laser beam emitting head 4, with flexible teacher's pointer 3
Body 1 contributes to the use of laser demonstration device when battery electric quantity deficiency, and the top of a body 1 is provided with
Laser emission button 5, the middle part of a body 1 is provided with upwards button 6 and down button 7.
As a preferred embodiment of the present invention, in described square groove 2, USB joint 21 is installed,
Square groove 2 is set and contributes to depositing of USB joint 21, additionally aid saving space.
As a preferred embodiment of the present invention, described flexible teacher's pointer 3 is positioned at laser beam emitting head 4
Left side.
