Description

The new pattern laser teacher's pointer
Technical field
The utility model relates to a kind of realia, especially a kind of new pattern laser teacher's pointer.
Background technology
Teacher's pointer has many implications: have plenty of the rod that teacher of the giving advice says that class hour indicator board book, picture are used; Have plenty of and refer to that the old times teacher is used for corporal punishment and spur student's the instrument that is similar to ruler; Also have a kind of implication to give advice exactly and educate teaching, for example say that so-and-so teacher takes over the teacher's pointer in so-and-so teacher's hand.
Along with the reach of science, teacher's pointer also updates, and laser pointer is arisen at the historic moment, and is an important weapon of guiding audience notice.Laser pointer is that less radio-frequency page turning laser pen uses computing machine USB technology, radiotelegraphy, integrating remote-control computer function and laser pointer, is laser pointer cooperation PC or laptop computer, the ideal demonstration instrument that is widely used in the occasions such as product demonstration, electronic teaching and academic conference in conjunction with the projector use.Controlled in wireless computer distance surpasses 20 meters, in the classroom or any one corner of meeting room operating computer flexibly and comfortably.The light that existing laser pointer penetrates is a branch of directional light, projects to form a bright spot on screen, and visual effect is bad, in order to change this phenomenon, makes the learner that a good academic environment be arranged, and wishes the respond well teaching teacher's pointer that design is new.
The utility model content
In order to overcome the deficiency of above-mentioned existing laser pointer, the purpose of this utility model is to provide a kind of new pattern laser teacher's pointer, and it adopts the laser head front end of existing laser pointer to be provided with movably lens.
In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of new pattern laser teacher's pointer is characterized in that: it by shell, bonnet, battery, open the light, movable button, spring, laser head, lens consist of; Described shell is cylindric, and left end is provided with bonnet, and front end is provided with and opens the light and movable button, and inside is provided with battery, laser head, spring and lens.
The beneficial effects of the utility model are: it can either conveniently be imparted knowledge to students, and can change again the bright spot state of laser head, makes the larger effect of teacher's pointer performance, and simple in structure, easy to use, widely applicable.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the utility model structural drawing
Fig. 2 is the utility model cut-open view
Fig. 3 is the utility model partial sectional view
1-bonnet, 2-shell, 3-switch, 4-movable button, 5-battery, 6-laser head, 7-lens, 8-spring in figure.
Embodiment
In Fig. 1, Fig. 2, the first embodiment shown in Figure 3, a kind of new pattern laser teacher's pointer is characterized in that: it by shell, bonnet, battery, open the light, movable button, spring, laser head, lens consist of; Described shell is cylindric, and left end is provided with bonnet, and front end is provided with and opens the light and movable button, and inside is provided with battery, laser head, spring and lens.
In Fig. 1, the second embodiment shown in Figure 2, described bonnet is cylindric, is connected with the left end of shell by screw thread, is used for being convenient for changing battery; Described battery is used for providing electric energy to laser head; Described laser head is used for electric energy conversion is become luminous energy; The vertical cross-section of described lens is identical with the shape in concavees lens cross section, and vertical cross-section is gradual change simultaneously, is used for the laser spots that laser head is launched is changed over the light of variable-length; Described opening the light is connected with laser head with battery by wire, is used for controlling the unlatching of laser head or closing.
In Fig. 2, the 3rd embodiment shown in Figure 3, described lens, movable button and spring form a device that changes light length, open switch, laser head can be launched a branch of directional light to lens, it is less that directional light is accepted lens cross sections concavity, form the straight line that length is less on screen, along with the increase of pressing backward movable button pressure, directional light is accepted lens cross sections concavity and is also increased, form the straight line that a length increases on screen, when unclamping movable button, lens are got back to original position under the effect of spring.
When using the utility model, at first will open switch, and then press down movable button, along with the increase of the pressure that presses down, the light that projects on screen is also elongated, simple in structure, easy to use.
