The electric etching pen comprises an upper pen shell and a lower pen shell, a heat absorption sleeve is arranged on the outer side of the upper pen shell, the lower end of the heat absorption sleeve extends to the lower pen shell, firstly, the electric etching pen is of a split structure, different storage batteries and power modules can be replaced according to needs, and secondly, positioning protrusions on the inner wall of the heat absorption sleeve extend into positioning grooves in the outer walls of the upper pen shell and the lower pen shell respectively. Therefore, relative rotation of the upper pen shell and the lower pen shell due to vibration can be prevented, loosening is avoided, and finally, the structure of the heat absorption sleeve can absorb part of heat during working, so that the electric etching pen can work better.

This invention discloses a reading and writing glasses with illumination function, belonging to the field of eyewear and intelligent lighting technology. It includes a frame, lenses, a left temple, a right temple, a power supply, and a control system. The outer side of the lens has a reading light-inlet slope and a reading light emitter, while the inner side has a writing light-inlet slope and a writing light emitter. The lens incorporates Type I and Type II scattering points to achieve directional and uniform light emission. The control system integrates a Hall sensor, a light intensity sensor, a distance sensor, a button switch, a touch sensor strip, and a micro-vibrator, providing dual-mode lighting for reading / writing, stepless dimming, ambient light adaptation, automatic power-off when the legs are closed, and posture vibration reminders. The lens surface is coated with multiple layers of anti-reflective, blue light-blocking, hardened, hydrophobic, and oleophobic films. This invention offers precise, shadowless illumination, ease of use, eye protection, and stable battery life, meeting the reading and writing lighting needs of students and office workers.
