Description
Technical field:
The present invention relates to a kind of pen core technology, related in particular to a kind of length adjustable pen core technology.
Technical background:
Existing pen is of a great variety, and corresponding pen core also is multifarious, and this has just caused in most of the cases also unmatched problem between pen core and the penholder, and a kind of pen core of model can only be used with the penholder of same specification, and is very inconvenient.
Summary of the invention:
The present invention's purpose is: propose a kind of length adjustable pen core and solve above-mentioned deficiency.
To achieve these goals, intend by the following technical solutions:
A kind of length adjustable pen core comprises the pen core that is made of nib, core pipe and hollow body three; It is characterized in that: the core pipe of above-mentioned formation pen core is provided with internal thread at that end that is not connected with nib, and the outer surface of the hollow body of above-mentioned formation pen core is provided with the external screw thread that matches with internal thread on the core pipe.
Maximum characteristics of the present invention: simple in structure, convenient and practical, appearance looks elegant, adjustable length, can with the supporting use of the penholder of different length.
Description of drawings:
Figure has illustrated a kind of structure embodiment of the present invention.
1, core pipe, 2, hollow body, 3, nib, A, the pen core that constitutes by nib, core pipe and hollow body three.
The specific embodiment:
A kind of length adjustable pen core comprises the pen core A that is made of nib 3, core pipe 1 and hollow body 2 threes; It is characterized in that: the core pipe 1 of above-mentioned formation pen core A is provided with internal thread at that end that is not connected with nib 3, and the outer surface of the hollow body 2 of above-mentioned formation pen core A is provided with the external screw thread that matches with internal thread on the core pipe 1.
Be not difficult to find out: when pen core A than the penholder that pen core A need to be installed in short-term, rotate hollow body 2 and make it to away from the motion of nib 3 directions, thereby make pen core A elongated; When pen core A is longer than the penholder that pen core A need to be installed, rotates hollow body 2 and make it near the motion of nib 3 directions, thereby pen core A is shortened.Realized that promptly the present invention can be applicable to the purpose of the penholder that length is different, not only reduced cost, also saved resource.
