Novel ball pen capable of preventing pen refill from being broken

Technical Field

The utility model relates to a ballpoint technical field especially relates to a novel prevent ballpoint that refill was broken.

Background

Ball-Point pens (Ball Point Pen), or ballpoint pens, are writing instruments that use a dry, viscous ink and are transferred to paper by means of a freely rotating Ball carried by the Pen tip. The ball-point pen has advantages of simple structure, convenient carrying, writing lubrication, and being suitable for duplicating, so that it is a pen using a minute rotary ball which is made of brass, steel or tungsten carbide and can release ink to paper when writing, and is enjoyed by all people from school students to clerks in office buildings. Ball-point pens are very different from reed pens, feather pens, metal nib pens and fountain pens, which are the predecessors of ball-point pens, and are writing tools for writing ink on paper by using the rotation of steel balls. After the world war II, the ball-point pen was introduced into China. The delicate businessmen make large advertisements for "ballpens" and open the way by means of the aftermarket of the exploded atom bomb in japan. In fact, a "ball point pen" is unrelated to an atom and has a similar pronunciation. Ball point pens have quickly become popular throughout the world. Only japan consumes 4 billion ball-point pens in a year. The ball-point pen can write because the steel balls in the pen head can bring out the quick-drying ink to be transferred to paper when rolling.

However, the existing ball-point pen has some defects in the using process, the refill in the existing cylindrical pen is not provided with a good protection device, and the refill is easy to damage when falling off in the using process, so that the requirement of a user cannot be met.
