Description

Multifunctional automatic pen free of shapening

The utility model relates to propelling pencil.

Propelling pencil, or be called " extensible pencil ", widely people prefer to use, but development is so far, its structure still exists the shortcoming that some wait to overcome, for example in some place, the employing more piece that has adds the pen core of cover, in case pen core is lost, will cause whole pen unrenewable.

The purpose of this utility model is to overcome its shortcoming in view of structurally there is above-mentioned shortcoming in existing propelling pencil and is studied, and provides a kind of pen core delivery device through improved multifunctional movable pencil.

The purpose of this utility model is achieved in that the automatic pen free of shapening of multipurpose, comprises that an outer pen tube, an inner pen tube, a jaw, a spring and push the cap for brush, is characterized in that the hollow tube that outer pen tube is formed in one; Inner pen tube also is a hollow tube, ccontaining pen core in it; Jaw is located at the inner pen tube front end, and its front end has and is the cracked prong claw of expanding shape; Pushing the cap for brush is ducted body also, is placed in the inner pen tube end; Push cap for brush below, inner pen tube is equipped with outward and can makes inner pen tube and jaw is outstanding or the spring of retraction outer pen tube; Pen core is that an end is that cylindrical casing clips the core heart and forms, and it is protruding that cylindrical casing is provided with a card, but cracked prong claw front end inner edge is provided with the inside protruding projection of proper buckle pen core card.

In the technique scheme, by pushing the effect of the cap for brush, make the protruding outer pen tube of inner pen tube, jaw breaks away from that outer pen tube constraint cracked prong claw opens and can't the fastening pen core, and the user can take off with the pen core of finishing, and treats that no pen core slides automatically, loosen the propelling movement cap for brush again, can make jaw clamp the back segment cylinder of pen core again and exercise usefulness again, solve the pen core disappearance, the shortcoming that causes lump-sum to scrap.

The utility model is described in further detail below by drawings and Examples.
