Laser pointer pen with anti-falling function

Abstract

The invention discloses a laser pointer pen with an anti-falling function. The laser pointer pen comprises a laser pointer pen body. A pen tail is fixedly connected with the top of the laser pointer pen body. A pen point is in threaded connection with the bottom end of the laser pointer pen body. Rotating bases are fixedly connected with the two sides of the outer surface of the laser pointer penbody respectively. The surfaces of the two rotating bases are each rotationally connected with a rotating rod. The invention relates to the technical field of laser pointer pens. According to the laser pointer pen, the elastic force of a telescopic spring is overcome through the attraction force of a first magnet and a second magnet; the rotating rods can rotate under wind resistance when the laser pointer pen longitudinally falls, then a connecting rod is driven to rotate, and then a slider is driven to slide on the inner surface of the groove to overcome the attraction force of the first magnet and the second magnet; a fabric is spread under the elastic force of the telescopic spring and the wind resistance, the longitudinal falling force of the laser pointer pen is effectively relieved,the pen point of the laser pointer pen is quite well protected, and the anti-falling function of the laser pointer pen is improved.

Description

technical field [0001] The invention relates to the technical field of laser pens, in particular to a laser pen with anti-drop function. Background technique [0002] Laser pointers, also known as laser pointers, pointing star pens, etc., are pen-shaped transmitters that are designed to be portable, easy to hold, and processed into laser modules with visible lasers. Fiber green laser pointer, also known as laser pointer, pointing star pen, etc., is a pen-shaped transmitter that is designed to be portable, easy to hold, and processed into a laser module with visible laser light. Common laser pointers include red light, green light, blue light and blue-violet light. It is usually used in reports, teaching, and tour guides to project a point of light or a line of light to point to objects, but it is not suitable for use in specific places, such as art galleries, zoos, etc. Improper use of the laser pointer may cause retinal damage or even blindness, and children should not us...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a laser pen with anti-fall function, which solves the problem that most of the existing laser pens are provided with rubber sleeves on the outer surface of the laser pen, which has poor protection performance and is easy to be damaged.
