Printing pen for conveniently replacing different pen heads

Abstract

The invention belongs to the technical field of printing pens, and particularly discloses a printing pen for conveniently replacing different pen heads. The printing pen comprises a printing pen body,a pen head shell, a solder joint, a printing joint, an internal thread sleeve and a radiating cylinder, the pen head shell is fixedly mounted at the left end of the printing pen body, groove blocks are fixedly mounted on the two sides of the inner wall of the pen head shell correspondingly, a fixing plate is in clamped connection with the inner wall of each groove block, a cylinder rod is fixedlymounted on the inner wall of each fixing plate, a nozzle is arranged at the left end of each cylinder rod, a heating ring is arranged on the outer wall of the right end of each nozzle, and the radiating cylinder is fixedly mounted on the inner wall of the left end of the pen head shell. The printing pen is scientific and reasonable in structure design, the internal thread sleeve has a fixing andmounting effects on a first external thread of the solder joint and a second external thread of the printing joint, replacing of the solder joint and the printing joint is facilitated, the dual-use effect of the printing pen is achieved accordingly, the printing pen is simple in structure, and the multi-function use effect of the product is improved.

Description

technical field [0001] The invention relates to the technical field of printing pens, in particular to a printing pen which is convenient for replacing different nibs. Background technique [0002] With the development of science and technology, 3D printing technology is more and more widely used in various fields. At the same time, 3D printing technology also appears in people's life in the form of more types of products. The handheld 3D printing pen is mainly divided into two types: hot-melt type and light-curing type. The light-curing 3D printing pen extrudes liquid photosensitive resin, which is cured and formed under the action of ultraviolet light. Its processing flexibility and final printing body There are certain advantages in the texture fineness, and the optional and combination types and ranges of photosensitive materials are also very flexible. [0003] Existing 3D printing pens cannot replace the tip of the pen, and the heating principle of the 3D printing pen...

AI Technical Summary

Problems solved by technology

[0003] Existing 3D printing pens cannot replace the tip of the pen, and the heating principle of the 3D printing pen is the same as that of the heating part and the soldering pen. However, the current 3D printing pen does not have the replacement of the soldering head, and the dual use effect of the printing pen cannot be fully realized. , when replacing and installing the pen head, the barrel rod and the feeding pipe are prone to shake, resulting in misalignment of the printing joint or soldering joint. Therefore, we propose a printing pen that is easy to replace different pen heads
