Ballpoint pen

Abstract

The invention discloses a ballpoint pen, and relates to the field of ballpoint pens. The ballpoint pen comprises an upper disc and a lower disc, a plurality of sliding grooves are formed in the surface of the upper disc, a through hole is formed in the surface of the upper disc, the inner walls of the sliding grooves are connected with surrounding rods in a sliding mode, the top view of the surrounding rods is in a circular shape, trapezoid-shaped grooves formed in the surface of the lower disc, trapezoidal blocks are slidably connected to the inner wall of the trapezoidal grooves, the surfaceof the trapezoidal blocks are fixedly connected with one end, away from the upper disc, of the surrounding rods, a core tube is fixedly connected to the surface of the upper disc, a supporting blockis adhered to the inner wall of the core tube, and butt joint grooves are formed in the lower surface of the supporting block. The ballpoint pen is unique in shape and particularly convenient to use,the shape of a traditional ballpoint pen is changed, and the ballpoint pen is interesting; meanwhile, the ballpoint pen can be conveniently held when the thickness is adjusted, the operation is simple, so that the problem that the existing ballpoint pen is relatively fixed and the thickness of the ballpoint pen is inconvenient to adjust along with the requirement of a user, and the writing hand feeling of the user can be influenced to a certain degree are effectively solved.

Description

technical field [0001] The invention relates to the technical field of ballpoint pens, in particular to a ballpoint pen. Background technique [0002] The ballpoint pen is a common and commonly used learning tool, which plays an important role in writing activities. With the continuous improvement of the ballpoint pen, the current form of the ballpoint pen has been basically finalized, and few people are making major changes and adjustments in its structure. However, the existing problems in the original structure cannot be solved well. [0003] The current ballpoint pen barrel is relatively fixed. When buying a ballpoint pen, you often choose a penholder that is more suitable for your fingers to use. For the convenience of mass production and production, the thickness of the ballpoint pen is less, so in the process of choosing a ballpoint pen, I often feel that It is either too thick or too thin. It feels extremely uncomfortable to use, and even affects the deformation of ...
