The purpose of the utility model is to add an electric adjustment function to the existing manual adjustment function of the gypsophila laser pointer. The pattern change of the electric adjustment is continuous and the changing speed is uniform. The laser pointer still has manual adjustment. With the adjustment function, users can actively choose electric or manual adjustment according to their needs.
The technical scheme of the laser pointer of the present invention is as follows: it includes a pen case, a laser module, the laser module is arranged in the pen case, the front end of the laser module is provided with a first grating sheet and a second grating sheet, the first grating sheet The second grating sheet is arranged at the center of the optical path of the laser module, and it also includes a motor. The motor is connected to the first grating sheet and driven to rotate by the motor. A button is provided on the surface of the pen case to control the opening and closing of the laser module and the motor. Optimally, the motor is set as a hollow shaft motor, the first grating sheet is set on the top of the hollow shaft, and is connected to the hollow shaft as a whole, and the hollow shaft is set at the center of the optical path of the laser engraver. Optimally, the motor is set as a micro motor, which is connected to the first grating sheet through a transmission mechanism, and the axis of the transmission mechanism is set at the center of the optical path of the laser module. Optimally.
The transmission mechanism is set as gear transmission. Optimally, the second grating sheet is arranged at the front end of the laser pointer, a shell is arranged outside, the shell and the pen shell are movably connected, and a manual adjustment knob is arranged outside the shell. This technical solution has the following technical effects: 1. The electric adjustment function is added to enhance the function of the laser pointer, and the pattern change of the electric adjustment is continuous and the changing speed is also uniform, which greatly increases the function of the laser pointer and Entertainment; 2. The laser pointer still has a manual adjustment function, and the user can actively choose electric adjustment or manual adjustment according to needs. 3. The assembly of structural parts and structural parts can adopt interference fit or threaded fit, which is very easy to assemble.
The most important component is the laser module, which is not easy to buy on Taobao, so it is best to go to the local electronic market and find a professional manufacturer’s direct sales store or agent to buy it. The diameter of the laser module we need should be smaller than the diameter of the flashlight, and the head of the blue laser pointer can be removed for separate use. As for the power of this laser module, it doesn’t matter. The laser diode will be replaced at the end, so you can buy the cheapest 5mW laser module. For example, the industrial 5mW adjustable focus red laser head costs about 20 yuan.
