Problems solved by technology

[0003] The tiny infrared emitter inside the optical stylus is usually installed inside the tip of the pen. Generally, the tip of the optical stylus is installed in a fixed way and is directly exposed to the outside world. When English teachers do not use it, they usually put the optical stylus Randomly placed on the desk, because the outer surface of the optical stylus is smooth, it is easy to roll and cause the optical stylus to fall. When the tip of the optical stylus touches the ground first and hits the ground, it will cause the tip to be installed inside the pen. The miniature infrared emitter of the computer is damaged, which affects the normal use of English teachers
[0004] A general optical stylus is usually equipped with electronics inside to provide power supply for the miniature infrared emitter. When the power of the electronics is insufficient for a long time, it is necessary to replace the electronics. Generally, when replacing the electronics, it is usually After placing the prepared new electrons according to the correct positive and negative poles, relying on the gravity of the electrons themselves, they fall into the interior of the optical stylus pen. When the electrons are falling, they are prone to side flipping, making the electrons unable to follow the normal The track falls, so that the electronics are stuck inside the optical stylus, which brings inconvenience to English teachers for the replacement of electronics
[0005] Usually, when English teachers write with an optical stylus, they usually have the habit of connecting pens. When writing with a signature pen, the thickness of the ink can be adjusted according to the strength of the English teacher's writing, so that the written The handwriting looks beautiful and easy for students to learn. However, the optical stylus uses a built-in micro-infrared emitter, and the projector captures the signal according to the built-in infrared camera, and then converts it into touch screen coordinates after being processed by the image processor. In order to convert the projection surface into a touch screen, the thickness cannot be adjusted according to the English teacher's writing strength, resulting in the same thickness of the continuous strokes and normal letters, which makes it difficult for students to distinguish and reduces the learning efficiency of students, so it needs to be improved

Embodiment Construction

[0036] Next, the technical solutions in the embodiments of the present invention will be described in connection with the drawings of the embodiments of the present invention, and it is understood that the described embodiments are merely the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0037] Such as Figure 1 to 9 As shown in the embodiment of the present invention, a portable English teaching device includes a stylus 1. The top and bottom ends of the inside of the touch pen 1 are fixedly mounted, and the internal activity socket of the fixed shell 2 has a fixed shell 2. Active block 3, one end of the movable block 3 extends above the fixed shell 2, and the other end of the fixing case 2 extends to the inside of the stylus 1, and the left end of the stylus 1 i...

Abstract

The invention belongs to the technical field of teaching aids, and discloses a portable English teaching device which comprises a touch pen, fixed shells are fixedly mounted at the top end and the bottom end in the touch pen, movable blocks are movably sleeved with the fixed shells, and one end of each movable block extends to the upper portion of the corresponding fixed shell. By arranging a movable block, a first connecting rod, a first spring and a movable block, when the movable block is pressed to enter the touch pen, the movable block is pushed to the right side of a conical block through the first connecting rod, the movable block is loosened, and due to the elastic force recovery effect of the first spring, the movable block is reset; therefore, the moving block enters the conical block through the first connecting rod, the situation that the optical touch pen falls off due to accidental rolling is avoided, a miniature infrared transmitter installed in the pen point is prevented from being damaged, and normal writing and using of an English teacher are facilitated.

Description

Technical field [0001] The invention belongs to the technical field of teaching equipment, and is specifically a portable English teaching device. Background technique [0002] With the improvement of teaching level, in order to provide students with better English teaching services, they will generally have projectors in the classroom, making the projector investment resources, and use optical touch pen use, optical touch The pen is provided with a micro-infrared transmitter, and the projector captures the signal according to the built-in infrared camera, and then transforms into touch screen coordinates after the image processor processing, thereby realizing the transfer of the projection surface into a touch screen, instead of the mouse and keyboard, and The shape is small and easy to carry it. [0003] The micro-infrared transmitter inside the optical stylus is usually mounted inside the nib, and the general optical stylus is installed in a fixed manner, and it is directly ex...
