The invention discloses a neutral pen core which is easy to replace the nib, which comprises a pen core tube, one end of the pen core tube is fixedly connected with a fixed tube, the surface of the fixed tube is movably connected with a connecting tube, and the connecting tube is The inner wall is fixedly connected with a positioning rod, and the surface of the fixed pipe corresponding to the position of the positioning rod is respectively provided with a through groove, a guide groove and a positioning groove, and the inside of the guide groove communicates with the inside of the through groove and the positioning groove respectively. In the present invention, when the connecting pipe and the pen core tube need to be disassembled, firstly, the pen core tube drives the fixed pipe to continue to be inserted into the inner wall of the connecting pipe, and squeezes the rubber ring and the sealing ring, so that the positioning rod can be moved out from the inner wall of the positioning groove, and then Turn the refill tube along the direction of the guide groove, so that the rubber ring can enter the through groove along the direction of the guide groove, and finally pull out the fixing tube from the connecting pipe to complete the disassembly work. Compared with the direct plug-in connecting pipe and The way the refill tube is installed is more convenient for installation and removal.
Description
technical field [0001] The invention relates to the field of office supplies, in particular to a neutral pen core which is convenient for replacing the pen head. Background technique [0002] As a writing tool, the pen core is widely used in daily life, study, and office. The general pen core includes a pen core tube and a pen core head. The pen core tube and the pen core head are connected by threads. The pen core tube is equipped with a writing For the liquid used, the head of the refill is equipped with a steel ball. When writing, the liquid in the refill tube slowly flows out through the steel ball at the front end of the refill head to achieve the purpose of writing. [0003] However, when the prior art is actually used, when there is no ink in the pen core tube, the existing device is inconvenient to disassemble the pen core head and the pen core tube, which makes it inconvenient to recycle the pen core head. Contents of the invention [0004] The object of the pres...
