Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1: a kind of pen as depicted in figs. 1 and 2, this comprises the upper penholder 1 of hollow, the lower pen rod 2 of hollow and pen core 3.
Pen core 3 is positioned at the hollow inner side of penholder 1 and lower pen rod 2, and upper penholder 1 inside top is also fixed with the securing member 12 for fixing pen core, and pen core 3 top is fixed in securing member 12.
The outer wall on lower pen rod 1 top is provided with limited impression 22, the inwall of upper penholder 2 bottom is provided with collar flange 11, the bottom of upper penholder 2 is socketed on the outer wall on lower pen rod 1 top, and collar flange 11 is positioned at limited impression 22 can be slided up and down, due to the existence of this limited impression 22, upper penholder 1 and lower pen rod 2 are not easy directly to be pulled open to be separated when axial opposing stretching; Also be provided with for the snap ring 21 with pen core CONTACT WITH FRICTION inside lower pen rod 1, when the collar flange 11 of upper penholder 1 lower inner wall slide in the limited impression 22 of lower pen rod 2 external wall of upper portion be in any position time, snap ring 21 can by the CONTACT WITH FRICTION between pen core, pen core is made to be fastened in snap ring 21, thus pen core is not easy mobile, particularly when writing state, playing the effect of fixing pen core, preventing pen core from sliding at axial direction.
Securing member is downward opening cylinder; The inside of cylinder is provided with the shoulder hole 13 for tight fit different size pen core, to coordinate the demand of different size pen core; When firmly when penholder 1 and lower pen rod 2, after collar flange 11 departs from the upside of limited impression 22, tight fit being formed with lower pen rod 2 outer wall, redraw until deviate from stretching of axially supporting or opposing.The securing member of fixing pen core upper end can not only coordinate snap ring 21 make pen core pen write using state time stability, can also to realize preventing when use do not write by pen block by the CONTACT WITH FRICTION of snap ring 21 and receive the function of not going back.
When pen be in write using state and do not write using state conversion time, only need the collar flange 11 of upper penholder 1 lower inner wall to slidably reciprocate can realize at the two ends up and down of the limited impression 22 of lower pen rod 2 external wall of upper portion.When collar flange 11 slides to limited impression 22 lower end, pen core stretches out, and is in and writes using state; When collar flange 11 slides to limited impression 22 upper end, pen core is regained, and is in and does not write using state.
