Description
Technical field
The utility model relates to a kind of gel ink pen that is convenient for changing pen core.
Background technology
Existing gel ink pen is more loaded down with trivial details when changing pen core, and pen cap drops easily sometimes, causes various troubles.
Summary of the invention
The shortcoming that the replacing pen core is more loaded down with trivial details and nib easily drops that exists in order to overcome existing gel ink pen, the utility model provides a kind of gel ink pen that is convenient for changing pen core.
The technical solution adopted in the utility model is:
Be convenient for changing the gel ink pen of pen core, comprise penholder, it is characterized in that: comprise that also inwall is provided with the shell that can relatively described penholder rotates freely of block-shaped protrusion and is located at rotating mechanism in the described shell, described rotating mechanism comprises with externally threaded the first rotating part with the second rotating part of internal thread, described the first rotating part be connected that the second rotating part connects by internal and external threads and described the first rotating part is fixed on the described shell; Described the second rotating part is provided with the groove suitable with described block-shaped protrusion, described the second rotating part can seesaw along described shell under the drive of described the first rotating part, drives the knob that described the second rotating part seesaws thereby an end of described the first rotating part is provided with rotatable described the first rotating part.
Further, described shell interfixes by screw and a buckle respectively with described penholder up and down.
Further, described screw and described shell fix and with described penholder matched in clearance.
Further, described buckle by with described penholder on the suitable fixing described shell of groove.
When the utility model used, the shell that only need to turn clockwise opened it, and then changes pen core, and the cycle shell gets final product; If the too short situation of pen core occurs, can rotate the first rotating part adjustment by vernier knob and get final product.
