Description

Marker pen capable of switching multicolor pen points Technical Field The utility model belongs to the technical field of marking pens, and particularly relates to a marking pen capable of switching multicolor pen points. Background The marking pen is a pen capable of writing marks or signs on one or more materials such as paper, wood, metal, plastic, enamel, and the like, and the marking pen in the prior art has single color, but is inconvenient to carry different color marking pens to mark different positions in daily use. In the prior art, a multicolor marking pen with the publication number of CN220332323U is characterized in that a second pen point is completely separated from the inside of a protective cover, a worker can change positions of the first pen point and the second pen point by rotating the pen body, and then different pen points are switched, but the multicolor marking pen has the following problems that the color switching is limited, only the double-color switching is supported, the requirement of multiple scenes cannot be met, the marking mode is single, and only a single straight line marking can be adopted, so that the marking pen capable of switching the multicolor pen points is provided. Disclosure of utility model The utility model aims to provide a marking pen with a switchable multicolor pen point, which can realize multicolor switching and has a changeable marking mode. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a marker pen of changeable polychrome nib, includes the pen shell, its both ends are equipped with nib one and nib two respectively, correspond the position and all be equipped with the core mouth, pen shell internal center is fixed to be equipped with the fixed plate, the symmetry is equipped with two perforation on the fixed plate, the refill subassembly runs through the perforation, the refill subassembly includes the shell that the internal center is equipped with the division board, insert the inner core at shell both ends, the refill head at inner core both ends and with shell both ends threaded connection's end cover, the refill subassembly can adjust from top to bottom through transmission structure, transmission structure includes through the go-between of being connected with the pen shell outside rotation, be located the outer ring inslot of pen shell and the ring gear of being connected with the rotation of go-between with fixed plate, the ring gear passes logical groove and external gear meshing, internal gear center and shell threaded connection, the shell lower extreme is equipped with the spout sliding fit that is equipped with on slider and the pen shell.
