Background technique

Wooden and paper-roll pencil is write conveniently to people's work, learning tape, but consumes the gloomy of a large amount of preciousnesses again simultaneously Woods resource.Existing wooden and paper-roll pencil, which needs to roll up, to be cut penholder and could write pen core sharpening, when pen uses 6-7cm When, dustbin often is thrown into because of holding a pen inconvenient, rolling up the paper after cutting, sawdust even more can not recycle use, cause very big Waste, and pencil-lead is exposed is easy disconnected core, and therefore, it is necessary to a kind of continuous core, pen core utilization rate is high, economizes on resources, environmental protection Pencil.

Summary of the invention

The purpose of this utility model provides a kind of multi-functional environment-protection pen aiming at above-mentioned the deficiencies in the prior art.

Three kinds of concrete schemes of offer of the utility model, scheme first is that: a kind of multi-functional environment-protection pen, including with external screw thread Pen cap and tool internal thread penholder, penholder is threadedly coupled with pen cap, and pen cap is provided with pen core, and the pen cap is also Equipped with internal screw thread, the pen core is equipped with external screw thread, and pen core is threadedly coupled with pen cap, and the end face of pen core upper end is equipped with groove, pen Bar upper end is also threaded with pen core adjustment device, and pen core adjustment device includes the protrusion with the matching grooves, raised bottom Portion is connect with a bottom plate front, and the bottom plate back side is equipped with tool apron, tool apron outer circle be equipped with the matched external screw thread of penholder, be equipped in tool apron Bellmouth, bellmouth is interior to be equipped with blade along hole wall.

The screw thread position dimidiation of pen cap described in the utility model is simultaneously flared out certain angle, pen cap and pen The two halves of screw thread position are drawn close to center when bar connects, and compress pen core by the two halves of pen cap, more firm pen core.

Groove described in the utility model is "-" type groove or "+" type groove, the convex shape of pen core adjustment device with it is recessed Groove shape is corresponding.

The external screw thread of pen cap described in the utility model and the internal screw thread of penholder are taper.

Pen core described in the utility model is pencil-lead or chalk core.

This programme working principle: dismantling penholder and expose pen core, removes pen core adjustment device from penholder upper end, pen core is adjusted The protrusion of device is filled in the groove of pen core upper end, and rotation pen core adjustment device can make pen core spinning in and out so as to adjust pen core The length for stretching out pen cap, after adjusting, by the pen tip position of the tool apron alignment pen core of pen core adjustment device, by rotating pen core Adjustment device makes blade cut pen tip position, modifies pen tip diameter, can freely adjust the diameter of pen tip according to actual needs.

Scheme second is that: a kind of multi-functional environment-protection pen, including with externally threaded pen cap and tool internal thread penholder, pen Bar is threadedly coupled with pen cap, and pen cap is provided with pen core, and pen core set is equipped in the pen cap, is socketed with pen core in pen core set Clamping device, pen core clamping device outer wall upper end are equipped with a circle supporting plate, spring are housed between supporting plate and pen core set, in the penholder Wall connects a cylinder, and when screwing penholder, bottom of cylinder, which squeezes supporting plate, moves down pen core clamping device while spring-compressed, One segment length of pen core clamping device bottom is divided at least two halves, and pen core set is stretched out simultaneously certainly in bottom when pen core clamping device moves down So open, penholder upper end is also threaded with tool apron, tool apron outer circle be equipped with the matched external screw thread of penholder, be equipped with taper in tool apron Hole, bellmouth is interior to be equipped with blade along hole wall.

This programme working principle: when rotation penholder declines penholder, the cylinder in penholder squeezes the branch of pen core clamping device Plate makes pen core clamping device bottom stretch out pen core set and opens naturally, and pen core is fallen by self weight, reaches when pen core stretches out pen cap When appropriate length, rotation penholder rises penholder, and pen core clamping device is acted on by spring force to be risen, and pen core is clamped by pen core and filled Clamping is set, after adjusting, by the pen tip position of tool apron alignment pen core, adjusting device by rotation pen core makes blade cut pen tip portion Position modifies pen tip diameter, can freely adjust the diameter of pen tip according to actual needs.

Scheme third is that: a kind of multi-functional environment-protection pen, including tool internal thread pen cap and have externally threaded penholder, pen Bar is threadedly coupled with pen cap, and the screw thread position dimidiation of penholder is simultaneously flared out certain angle, in the screw thread position of penholder Equipped with pen core, the two halves of screw thread position draw close compression pen core to center when pen cap is connect with penholder, and penholder upper end also screw thread connects Be connected to tool apron, tool apron outer circle be equipped with the matched external screw thread of penholder, be equipped with bellmouth in tool apron, be equipped in bellmouth along hole wall Blade.

This programme working principle: the screw thread position of penholder draws close compression pen core to center when screwing pen cap, unscrews pen tip When set, the screw thread position of penholder is flared out, and can arbitrarily adjust pen core extension elongation at this time, after regulating, tool apron is aligned The pen tip position of pen core, adjusting device by rotation pen core makes blade cut pen tip position, pen tip diameter is modified, according to practical need Want freely to adjust the diameter of pen tip.

Pen core described in the utility model is black or colour.

Pen core diameter described in the utility model is 2 ~ 10mm.

The utility model has the advantage that the configuration of the present invention is simple, at low cost, continuous core, and pen core utilization rate is high, saves Resource, environmental protection, has a vast market space.
