Pluggable quick-release type anti-reflux self-locking plectrum refill

Abstract

The invention discloses a pluggable quick-release type anti-reflux self-locking plectrum refill, and relates to the technical field of pluggable anti-reflux locking refills. The pluggable quick-release type anti-reflux self-locking plectrum refill comprises a refill body, a first clamping head and a pen point, the top end of the refill body is movably connected with the first clamping head in a clamped mode, and the pen point is arranged at the top end of the first clamping head. Micro-elastic rods are fixedly connected to the upper outer surface and the lower outer surface of the left side of the refill body, and a polygonal clamping connector is fixedly connected to one end of each micro-elastic rod. A second clamping head at one end of tweezers is attached to the surface of the pen point, the second clamping head is clamped to a square empty groove in the surface of the pen point, a friction plate is used for attachment and extrusion, the pen point is rapidly pulled out from one end of the refill body by pulling the tweezers, and the characteristic that the pen point is replaced and clamped is achieved. The problems that the pen point is tedious and complex in process manufacturing, ink is discarded after being used up, and waste is caused are solved, and the effect of rapidly pulling out and replacing the pen point is achieved.

Description

technical field [0001] The invention relates to the technical field of plug-in and dismantling anti-backflow locking refills, in particular to a plug-and-pull quick-release anti-backflow self-locking pick refill. Background technique [0002] The pen is a kind of stationery commonly used in people's life. It is used for writing or drawing. The pen core is an important part of the pen, and the replacement of the pen core is a process that often occurs during use. The conventional replacement of the pen core needs to disassemble the whole pen. , to reassemble the old refill-related accessories with the new refill, the whole process is cumbersome and consumes the precious time of the user. There are following problems at prior art: [0003] 1. When the existing ballpoint pen is in use, the ink inside the pen core is used up, or the pen head is damaged and the internal ink is not used up, so it is often discarded. The manufacturing process of the pen head is cumbersome and comp...

Problems solved by technology

[0005] The invention provides a plug-and-pull quick-release anti-backflow self-locking pick pen refill, one of the purposes of which is to have the characteristics of replacing and clamping the nib, so as to solve the cumbersome and complicated manufacturing of the nib, and the use of ink. It will be discarded after it is finished, which will be a wasteful problem; another purpose is to solve the problem that the internal ink will flow out when the nib is pulled out, so as to achieve emergency cleaning of the internal ink when the nib is pulled out. closed effect
