The pen capable of freely retracting has the beneficial effect that the ink pipe cap is connected with the main sleeve through the thread, so that the length of the pen can be changed by lightly rotating the main sleeve; and the auxiliary sleeve is arranged outside the main sleeve and can be used for covering exposed threads on the ink pipe cap, so that the trouble of hurting hands by exposed threads on the ink pipe cap is avoided.
Description
(1) technical field
The present invention relates to a kind of pen, particularly a kind of freely telescopic pen.
(2) background technology
Present pen; Because simple in structure, function ratio is more single; Many inconveniences are also arranged in use, as present students in middle and primary schools practise fountain pen word or when writing with pen pen holding posture be not standard very, generally all be because the penholder of pen is oversize or too short causing; And the pen length under the prior art is nonadjustable, can't satisfy all users' needs.

The present invention realizes through following technical scheme:
A kind of freely telescopic pen comprises handwriting and ink pipe cap, it is characterized in that: said ink pipe cap connects main sleeve pipe through internal thread, and main sleeve pipe is through external screw thread auxiliary connection sleeve pipe.
The invention has the beneficial effects as follows: the ink pipe cap rotates the length that main sleeve pipe can change pen gently through the main sleeve pipe that is threaded; And main jacket application is provided with secondary sleeve pipe, and secondary sleeve pipe can cover the screw thread that the ink pipe cap exposes, and has avoided because the screw thread that the ink pipe cap exposes is hindered the trouble of hand.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is a structural representation of the present invention;
Among the figure, 1 handwriting, 2 ink pipe caps, 3 internal threads, 4 main sleeve pipes, 5 external screw threads, 6 secondary sleeve pipes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises handwriting 1 and ink pipe cap 2, and ink pipe cap 2 connects main sleeve pipe 4 through internal thread 3, and main sleeve pipe 4 is through external screw thread 5 auxiliary connection sleeve pipes 6.
Adopt a kind of freely telescopic pen of the present invention,, under the effect of internal thread 3, rotate main sleeve pipe 4, can carry out stepless elongating or shortening, reach user's demand the length of pen according to user's needs; When because rotate main sleeve pipe 4, when the screw thread on the ink pipe cap 2 exposes, can be under the effect of external screw thread 5, revolute pair sleeve pipe 6, the screw thread that will expose covers, and has avoided because the screw thread that ink pipe cap 2 exposes is hindered the trouble of hand.Like this, can change the length of pen arbitrarily, can avoid again satisfying the requirement of all users pen length because the screw thread that exposes is hindered the trouble of hand.
