Description

The multifunctional pen that refill expansion is adjustable

The utility model relates to a kind of pen, the adjustable multifunctional pen of particularly a kind of refill expansion.

The pencil that tradition is used, all be that wooden stick central authorities parcel center pencil-lead constitutes, this pencil, because the lead for retractable pencil bar is thicker, and its outer wrapping wooden stick, so the not frangibility of writing, but because the pencil consumption is big, the timber that expends every year is also quite huge, if excessively cut the destruction that the valve timber resources brings ecological environment therefrom, consequence is serious; For avoiding using pencil to waste timber resources in a large number, people are through concentrating on studies, invented the propelling pencil that generally uses now, the shell of this pencil generally all is to use plastic production, and pen core is generally made certain dimensions, need not cutter and cuts, but because its pen core is generally all less, writing is very easy to fracture, and can't use as drawing, and brings the deuce to pay to study and work.No matter be the former traditional pencil, or latter's propelling pencil, its function is single, promptly can only use as pencil, and can't the double as ballpoint pen and use such as water core pen.

The purpose of this utility model is to provide a kind of improved refill expansion adjustable multifunctional pen, and it not only has functions of use such as pencil, ballpoint pen, and can avoid effectively using timber and the significant wastage of bringing timber resources.

The purpose of this utility model is achieved in that the multifunctional pen that this refill expansion is adjustable, comprise the shaft of a writing brush and the cap for brush, the pen of the shaft of a writing brush is chewed end and is provided with pen core and stretches out the hole, its tail end is the pen core installing port, the cap for brush connects with the shaft of a writing brush is removable, shaft of a writing brush inner tubal wall vertically offers a groove, shaft of a writing brush tail end pen core installing port inwall is provided with the location convex shoulder, be set with a helix tube in the shaft of a writing brush, be connected with a pen core in the helix tube and connect rod, pen core connects the excellent transverse arm that is provided with of going up and places in the groove of shaft of a writing brush inwall, pen core connects rod and can vertically move up and down along helix tube, the tail end of helix tube tightly is enclosed within on the projection that places the pullover central authorities of rotation on the convex shoulder of shaft of a writing brush tail end pen core installing port endoporus location, is pulloverly fixed by the cap for brush and rotate.

The utility model is because only need to adopt the helix tube mobile device on original sleeve pen, so structure is simple especially; Can change the pen core of different purposes as required at any time because the pen core connection rod of pen core is installed simultaneously,, both can be used as pencil and used, can be used as ballpoint pen, water core pen use again so realize requirement easily as multifunctional pen.
