Description

A kind of pen

The utility model relates to a kind of writing implement.

At present the pen that uses of people is various, and pencil (comprising propelling pencil), ball pen (comprising monochrome, double-colored, three looks etc.), pen, pen and ball pen double-purpose pen or the like are arranged.But so far, the double-purpose pen that does not also have pencil and ball pen to combine, and people need to use the occasion of pencil and ball pen simultaneously be a lot, as the student when doing one's assignment, scientific and technical personnel when drawing, if often more change-fountain pen just seem not too convenient.

The purpose of this utility model just is to provide a kind of simple double as ball pen simultaneously of novel structure and the pen of pencil.

The purpose of this utility model reaches by following measures: a kind of pen, comprise penholder, pen core, said pen core is a refill for ball-point pen and a propelling pencil core, above-mentioned two pen cores place the two ends of a slide block respectively, said penholder is divided into two sections and be linked together by tongue and groove, said slide block is slidingly connected for one section by a key and penholder, and slide block one end has the internal thread that is had on another section of external screw thread and penholder and links.

Below in conjunction with embodiment (accompanying drawing) the utility model is further described.

Fig. 1 is the utility model overall construction drawing.

The utility model, comprise that penholder, pen core, pen core are a refill for ball-point pen 2 and a propelling pencil core 3, two pen cores place the two ends of slide block 4 respectively, penholder divides two section 1 and 5, two sections are linked together by emboss pit 7, slide block slidingly connects by key 6 and penholder section 1, and wherein the form of key 6 is to adopt spline for well, and one section of slide block has the internal thread that is had on another section 5 of external screw thread and penholder and links.What be worth to propose is, the emboss pit of above-mentioned two sections connections of penholder must guarantee that on fit dimension penholder can realize hand rotation for two sections, and elasticity is suitable during rotation.The internal structure of propelling pencil core is identical with structure in the existing propelling pencil.

During use, assemble by diagram, two is equipped with refill for ball-point pen and propelling pencil core respectively.If need to adjust the length of pencil-lead, then manually make two sections relative rotatings of penholder, then slide block is left and right moves, pencil-lead is constantly sent left, refill for ball-point pen and then puts in together and stretches out simultaneously, till pencil-lead reaches suitable length, in the time of outside refill for ball-point pen stretches out penholder, just can be used for writing; If need to change refill for ball-point pen, then only need spin off that pen head of ball pen, load onto new refill for ball-point pen again; If need to change pencil-lead, then need the penholder of other end is spun down, pencil-lead and then withdraws from the endoporus of slide block together, changes pen core then.

By above-mentioned explanation, compared with prior art, the utlity model has and double as simultaneously ball pen With the function of propelling pencil, reached a dual-purpose purpose, simple in structure, novel, the user Just.
