Description

Pen

The invention relates to a writing instrument, in particular to a writing instrument which can be applied to various lengths and thick and fine refills, which can repeatedly use the writing instrument to reduce the number of discarded writing instruments.

According to the conventional pens, especially the pens or ballpoint pens that can replace the refills, usually the refills produced by each manufacturer have a specific thickness and length to be suitable for their pens, and the chance of replacement is very low. When the original refill is not available, the pen has to be discarded, which will cause waste and increase the burden on the environment.

At present, the prior art patents, such as the "Multifunctional Universal Tool Pen" of the Republic of China No. M297854, disclose a multifunctional universal utility pen, which mainly includes a first rod body, a second rod body, and a first a tripod body, a first joint body, a second joint body, a first clamping device, a second clamping device, and a clamp. However, the purpose of this patent is to replace a variety of different components, such as knives, screwdrivers, saws, etc., but can not replace the refill.

For example, the "rotary writing instrument" of the Chinese Patent No. I317326 discloses a rotary writing instrument comprising a tubular mechanism, a turning mechanism, a heart-shaped seat and a positioning mechanism. The barrel mechanism includes a hollow pen tube having an inner peripheral mask having a first guide portion extending helically up and down. The turning mechanism comprises a turning cap disposed on the pen tube, and a linking plate which can be rotated by the adjusting cap to be locked in the pen tube. However, the structure of the patent is complicated, the cost is high, and the refill is required to be pushed out when the refill is replaced, which is inconvenient to use.

For example, the "Refillable Structure for Ball Pens and Ballpoint Pens" of the Republic of China No. 322848 patent discloses a refill structure that can be used in ball pens and ballpoint pens, which is mainly used in a standard specification of steel balls. The near end of the pen refill is provided with a broken ring groove at the same length as the standard pen refill, and a broken portion is formed, so that when the pen holder is to be used, the broken portion can be directly removed and the steel ball can be removed. The pen refill and the ball pen pen are in normal assembly. However, this patent only applies to specific refill specifications.

For example, in the Republic of China No. 377611 patent, "a variety of refillable pens can be planted", which discloses a pen that can be planted with a plurality of refills, including a pen and a plurality of refills, the pen end is provided with a number The guiding groove has a shape of a wide middle section and a narrower end, and a clamping hole is provided on both side walls of the narrower ends, and the refilling device is arranged in the pen holder for generating Writing function. Although the patent can be replaced with a variety of different refills, its shape and shape can not be changed, it is a flaw in the United States.

Therefore, it is necessary to design a new type of writing instrument to overcome the above drawbacks.

It is an object of the present invention to provide a writing instrument that can be used to replace various types of pens that are commercially available in a variety of lengths and thicknesses.

The object of the present invention is to provide a writing instrument which is simple in structure, convenient to use, and repeatable, to reduce waste pen tube, economical and environmentally friendly.

In order to achieve the above object, the writing instrument of the present invention comprises: a pen head, which is hollow, has a first thread thereon, and has a first stop at a middle portion of the first thread, the end of the first thread The portion has a plurality of mutually separated collets; a cap having a hollow shape with a second thread on the inner side for screwing the first thread; and a tube having a hollow chamber for receiving a core, And the inner side of the two ends has a third thread and a fourth thread, the third thread is screwed to the first thread of the pen head; a venting cap can be placed in the hollow chamber and has an air hole; a cover, one end of which can be received in the air hole cover, has a fifth thread thereon, and the end of the fifth thread is expanded to form a second stop; 俾 by adjusting the cap and the tip of the pen And the position of the vent cover and the pen cover to achieve the purpose of the universal refill.
