Abstract
The invention belongs to the technical field of pointers and provides a multifunctional pointer combining a pointer, a laser pointer and an oil pen. According to the technical scheme, the multifunctional pointer comprises a handheld portion and a telescopic portion, a switch is arranged on the outer wall of the handheld portion, the laser pointer is arranged inside the handheld portion, a cylinder lens is arranged at one end of the laser pointer, a transparent glass cover plate is arranged at one end, close to the cylinder lens, of the handheld portion, the other end of the handheld portion is connected with the telescopic portion, and the extending end of the telescopic portion is movably connected with the oil pen. The telescopic portion is composed of multiple sections of sleeves, the extending end of the telescopic portion is connected with the oil pen through a thread, and both the handheld portion and the telescopic portion are made of stainless steel. According to the multifunctional pointer, the pointer, the laser pointer and the oil pen are combined together, a lecturer can conveniently carry and use the multifunctional pointer, and working load during teaching is reduced for a teacher.
Description
Technical field
The multi-functional teacher's pointer of the present invention, belongs to teacher's pointer technical field.
Background technology
Teacher's pointer is accompanied by teaching and is in use to now always, teacher's pointer mostly in the past is wooden, this teacher's pointer carries very inconvenient, in the development of teaching, laser pointer has replaced wooden teacher's pointer gradually, but, the only luminous point that diameter is very little that laser pointer emits, in the time of like this on projecting blackboard or curtain, visual effect is very poor, student stares at the time of luminous point and has grown, can cause eye fatigue, visual impairment, and, in teaching process, some needs the place of appointment higher, some place is lower, therefore, often need teacher's pointer and laser pen to combine, in addition, lecturer often needs to carry a lot of teaching aids class hour saying, often can occur to omit or Loss, affect teaching efficiency and quality of instruction.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical matters to be solved is for providing a kind of multi-functional teacher's pointer that teacher's pointer, laser pen and oil pen are combined.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: multi-functional teacher's pointer, comprise Handheld Division and pars contractilis, on the outer wall of described Handheld Division, be provided with switch, the inside of described Handheld Division is provided with laser pen, and one end of described laser pen is provided with right cylinder lens, and described Handheld Division is provided with transparent glass cover-plate near one end of right cylinder lens, the other end of Handheld Division is connected with pars contractilis, and the elongated end of described pars contractilis is connected with oil pen.
Described pars contractilis is comprised of more piece sleeve pipe.
The elongated end of described pars contractilis is connected with oil pen by screw thread.
Described Handheld Division and pars contractilis are stainless steel.
The present invention compared with prior art has following beneficial effect.
1, the present invention combines teacher's pointer, laser pen, and when light is better, the effect of laser pen will weaken, and at this moment pars contractilis of the present invention can be pulled out and is used as teacher's pointer; When light is darker, the effect of teacher's pointer will variation, at this moment, pars contractilis of the present invention is retracted, and it is lightly short and small that integral body becomes, and can make laser pen and use.
2, one end of the present invention is provided with oil pen by screw thread, after pars contractilis of the present invention is retracted, can utilize oil pen to write in board of education, after oil pen's ink is finished, can also change oil pen, convenient and practical.
3, on laser pen of the present invention, be provided with right cylinder lens, these lens can amplify the luminous point of laser pen, strengthen the visual effect of laser pen.
4, Handheld Division of the present invention is provided with transparent glass cover-plate in the one end near right cylinder lens, so neither can affect the effect of laser pen. can prevent that again dust from entering in Handheld Division.
5, Handheld Division of the present invention and pars contractilis are stainless steel, generous attractive in appearance, durable.
6, the present invention combines oil pen, teacher's pointer and laser pen, facilitates lecturer to carry and uses, and has reduced the workload of lecturer's teaching.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
