A kind of pen
Technical field
The present invention relates to a kind of pen, thereby particularly a kind of cap and penholder body link together and prevent the drop pen of loss of cap.
Background technology
At present, the cap of known pen separates with penholder body, during use, cap is partly extracted from nib, places on one side, so just easily causes the loss of cap.Also having some caps is the pen head parts that can be stuck in penholder, can avoid although it is so the loss of cap as far as possible, if but drop one do not note losing on the ground or while extracting cap.
Summary of the invention
In order to allow cap can not lose, the invention provides a kind of pen, this cap and penholder link together by connecting rod, and cap is lost with regard to not departing from penholder like this.Dop on connecting rod is embedded in guide channel.The dop being slidably connected on bar, cap just can put nib or nib.
The technical scheme that the present invention solves its technical problem is: a kind of pen, comprise holddown groove 1, penholder body 2, slip dop 3, the bar 4 that is slidably connected, guide channel 5, fixed chuck 6, cap 7, it is characterized in that, cap 7 is to be linked together by the bar 4 that is slidably connected with penholder body 2; Penholder body 2 is linked together by slip dop 3 with the bar 4 that is slidably connected; Slip dop 3 is embedded in guide channel 5; Guide channel 5 is in penholder body 2; Guide channel 5 is that quantity is one to three.
The invention has the beneficial effects as follows, when having met the normal usage function of pen, thereby cap and penholder body can be linked together and better prevent the loss of cap.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the structural representation of a kind of cap of the present invention when nib.
Fig. 2 is the structural representation of a kind of cap of the present invention when nib.
Fig. 3 be a kind of guide channel of the present invention over against time structural representation.
In figure: 1, holddown groove 2, penholder body 3, slip dop 4, the bar 5 that is slidably connected, guide channel 6, fixed chuck 7, cap.
The specific embodiment
With reference to diagram, penholder body 2 links together by be slidably connected bar 4 and slip dop 3 with cap 7, during use, moves up and down slip dop, and slip dop 3 moves in guide channel 5.While moving to nib part, cap 7 covers nib, and the fixed chuck 6 of cap 7 is stuck in holddown groove 1, and cap 7 is just fixed on nib and partly protects nib.While using, from nib, partly extract cap 7, mobile slip dop 3, cap 7 arrives pen head parts, by cap 7 upsets 180
0rear insertion nib, the fixed chuck 6 of cap 7 is stuck in holddown groove 1, and cap is just fixed on pen head part.Whole process cap 7 is all connected by the bar 4 that is slidably connected, and can not drop.
