Background technology
Wooden and paper-roll pencil is write conveniently to people's work, learning tape, but consumes again a large amount of valuable forest reserves simultaneously.Existing wooden and paper-roll pencil needs volume to cut penholder and is fined away by pen core just can write, when 6-7cm used by pen, often thrown into dustbin because holding a pen inconvenience, volume cut after paper, wood chip cannot reclaim use especially, cause very large waste, and pencil-lead exposes easily disconnected core.Therefore, need a kind of continuous core, pen core utilization rate high, economize on resources, the pencil of environmental protection.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of adjustable pen core pencil improving pen core utilization rate is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of pencil of adjustable pen core, comprise penholder, the pen core be arranged in penholder cavity, the pen cap being arranged on penholder lower end, pen plug, pen core propeller is provided with in described penholder cavity, pen cap is threaded with penholder through pen core tip
It is characterized in that, described pen core upper end sidewall is provided with projection, described pen core propeller is made up of helix tube, the rotary handle that is arranged on helix tube upper end, rotary handle is connected to helix tube upper end by cylindricality contiguous block, pen core is placed in helix tube inner chamber, projection is placed in the gap of adjacent two spiral coils of helix tube, and helix tube, pen core are coaxial;
Helix tube is rotatably connected in penholder inner chamber by cylindricality contiguous block, and rotary handle is placed in outside the port of penholder upper end, and described penholder inwall is axially arranged with the rail groove matched with projection, and projection is placed in rail groove.
Described cylindricality contiguous block sidewall is provided with annular protrusion, and penholder inwall is provided with the cannelure matched with annular protrusion, and helix tube is rotatably connected in penholder cavity by annular protrusion, cannelure.
Be provided with pen core sandwich device in described pen cap, pen core sandwich device is the tapered tubular matched with pen cap inwall tapering, and the maximum gauge place of pen core sandwich device is provided with defining flange.
Described pen plug is connected to rotary handle upper port.
Described helix tube lower end is placed in pen core sandwich device upper port.
Described pen cap inwall minimum diameter place is provided with sandwich mouth.
The spacing of adjacent two spiral coils of described helix tube is 4-10mm.
In the present invention, pen core propeller is made up of helix tube, rotary handle, and helix tube is rotatably connected in penholder cavity by annular protrusion, cannelure, and the projection of pen core upper end coordinates with the rail groove on penholder inwall.The present invention needs knockout in use, only need pin penholder on the other hand, pin rotary handle on the other hand, by rotating rotary handle clockwise or counterclockwise, helix tube is driven to rotate in penholder cavity, thus have the trend driving pen core to rotate in helix tube, but the projection of pen core is stuck in the axial rail groove arranged of penholder inwall, pen core can not be rotated along with swivelling pipe, projection can only move down along adjacent two fillets of screw, projection is simultaneously also along rail groove slide downward in penholder inner chamber, thus pen core moves below penholder, pen core skids off outside nib cap, realize the continuous knockout of pencil.Even if be also left several centimeters after pen core uses for a long time, pen core also can be released penholder and continue outward to use by pen core propeller.On helix tube, the spacing of adjacent coils is 4-10mm, revolves the rotary handle that turns around, and can ensure pen core knockout 4-10mm.
The setting of pen core sandwich device, sandwich mouth is all that protection pen core is by its continuous core, and the defining flange of pen core sandwich device is to allow it be fixed in pen cap in order to make pen core firm in penholder cavity.The present invention is skillfully constructed, and structure is simple, and manufacture easily, cost is low, continuous core, and pen core utilization rate is high, economizes on resources, environmental protection, and user can be assisted to grasp correct holding posture, has the wide market space.

Detailed description of the invention
A pencil for adjustable pen core, comprises penholder 1, the pen core 2 be arranged in penholder cavity, the pen cap 3 being arranged on penholder lower end, pen plug 4, is provided with pen core propeller in penholder cavity, and pen cap is threaded with penholder through pen core tip.
Pen core 2 upper end sidewall is provided with projection 5, and pen core propeller is made up of helix tube 6, the rotary handle 7 that is arranged on helix tube upper end, and pen plug 4 is connected to rotary handle 7 upper port.Rotary handle is connected to helix tube upper end by cylindricality contiguous block 8, and pen core 2 is placed in helix tube inner chamber, and projection 5 is placed in the gap of adjacent two spiral coils of helix tube, and helix tube, pen core are coaxial, and the spacing of adjacent two spiral coils of helix tube 6 is 4-10mm.
Cylindricality contiguous block 5 sidewall is provided with annular protrusion 10, and penholder 1 inwall is provided with the cannelure matched with annular protrusion, and helix tube is rotatably connected in penholder cavity by annular protrusion, cannelure.Rotary handle 7 is placed in outside the port of penholder upper end, and penholder 1 inwall is axially arranged with the rail groove 9 matched with projection 5, and projection is placed in rail groove, and rail groove has four, is arranged on penholder inwall equably, and projection is as in arbitrary rail groove.
