Portable pressure-sensitive scanning and projecting pen

Abstract

The invention relates to the technical field of pens and especially relates to a portable pressure-sensitive scanning and projecting pen which comprises a pen holder, a pen core and a pen cap, whereinthe pen cap is in threaded connection to the front part of the pen holder, a pen point of the pen core penetrates through the pen cap, a holding area of the pen holder is provided with silica gel, apressure sensor is arranged at the bottom of the silica gel, the pen core is arranged in the pen holder, the upper part of the pen core is connected with a fixed sleeve, a locating protrusion is arranged at the upper part of the fixed sleeve, a micro electric push rod is fixed to the top in the pen holder, a locating groove is formed in the front part of the electric push rod, the locating protrusion and the locating groove are matched with each other, the micro electric push rod is driven by a motor, and the pressure sensor can control the motor to work. The pressure sensor is arranged underthe silica gel, so that when the silica gel is stressed, the pressure sensor can drive a pusher in the pen holder to control the pen core to be in and out. Therefore, not only is a convenience degreeimproved, but also damage to the pen core by accident is avoided at the same time.

Description

technical field [0001] The invention relates to the technical field of pens, in particular to a portable pressure-sensitive scanning projection pen. Background technique [0002] There are many inconveniences in traditional signature pens whether they are capped or spring-loaded. When we finish writing every time, because we forget to snap back the pen cap or forget to press the pen back to its original position, we may inadvertently cause damage to the pen core, and the ink may also be stained on clothes and other unnecessary places. In daily life and study, we often need to display personal ideas through videos, PPT and other forms, as well as conduct effective group work reports. When we want to express these ideas, we will use projection devices, and general projection devices have problems such as large size, heavy weight and must have power supply devices. Inconvenient, unable to display, share, etc. At the same time, in the process of reading, we will inevitably en...

Problems solved by technology

When we want to express these ideas, we will use projection devices, and general projection devices have problems such as large size, heavy weight and must have power supply devices. Inconvenient, unable to display, share, etc.

At the same time, in the process of reading, we will inevitably encounter beautiful sentences or important academic articles that need to be recorded, but manual excerpts are very tiring and slow, and may even cause content errors due to personal mistakes
