Lock tube pen laser pointer
A reduced-tube pen-shaped laser pointer similar in appearance to a general shuttle-shaped high-end pen. Including nib holder, upper and lower pen tubes, lens holder, laser generator assembly, battery, etc. With the special structure design of the lens holder, nib holder and laser generator assembly, the above laser pointer can still be in the form of a reduced tube standard pen under the condition of using AAA SIZE (commonly known as AAA battery) . Due to the advancement of science and technology, the traditional indicator rods used as instructions for speakers or presenters and teachers have gradually been replaced by high power laser pointer. Among the various types of laser pointers, pen-shaped laser pointers are the most widely used. Preference, the main reason is that the tubular pen-shaped laser pointer is easier to carry and hold than other types of laser pointers (such as flashlights) in size and shape, so this kind of pen-shaped laser pointer can be described as a laser pointer. The main product form of the device.

The principle of the structure of the laser pointer is that electric energy is used by the circuit on the circuit board to excite a laser diode to emit light, and the focusing structure is adjusted to converge the beam to emit it. Laser diodes, focusing adjustment structures, circuit boards, batteries and other components are indispensable; however, for pen-shaped laser pointers to assemble these components in a relatively limited space, there are actually quite a few technical bottlenecks and limitations that need to be overcome. If the battery with a very high proportion of the overall volume is replaced by a battery with a very small volume such as a special specification (such as a mercury battery).
The lock tube-shaped laser pointer can greatly reduce the volume of the pen-shaped laser pointer; using special specifications of batteries as the power supply of the laser pointer, in addition to the high price and high cost of use, special specifications of batteries are not very popular. It is not easy to purchase. In addition, its power supply time is quite short, which is also one of its shortcomings. Due to these limitations, the focus adjustment structure (that is, the lens holder) in the laser pointer must be placed The front end of the green laser pointer structure causes the current pen-shaped laser pointers to have the shape limitation of a round tube shape, and there is no other shape with more changeable beauty.
