Abstract

Fully can enter the point protector that row write is drawn using pencil the invention belongs to a kind of.Mainly it is made up of the body of rod, chuck and gripping sleeve.During using the present invention, the pencil that length can be cut when being as short as holding difficulty is injected in its cylindric elastic clamping piece, pencil stub is withstood in its interior truncated cone-shaped nib support, now inwardly screw gripping sleeve, the interior truncated cone-shaped face of gripping sleeve will inwardly advance and oppress the platform shape face of clamp clip, cause the elastic clamping piece for being combined into cylindrical shape to shrink internal diameter and clamp pencil, and the interior truncated cone-shaped nib support of penholder chuck inner chamber also holds pencil nib naturally, make a concerted effort at two stabilized pencil, reaching the holding point protector body of rod can not loosely with the pencil goal of the invention for easily writing picture as one wishes.Conversely, when unscrewing its gripping sleeve, chuck loosens easily can then be taken out pencil.

Description

Point protector
Art
The instrument write or paint the invention belongs to a kind of word, more particularly to how fully to be carried out using pencil Write a kind of point protector of picture.
Background technology
At present, in painting tool is write, pencil is used widely.But there is also very big wave using pencil Take situation.It is well known that production pencil needs to consume the straight suitable wood resources of a large amount of textures, this material is become a useful person not Easily, it is increasingly rare, possibly even cause environmental degradation using excessive.When pencil is used to a certain extent, Both pencil used holding unstable, was about cut when being as short as 10 centimetre length, will typically be dropped, though this feelings It is small, but be then a kind of extremely serious wasting of resources from the actual conditions analysis that pencil is widely used, it is One of the reason for causing environmental degradation.
The content of the invention
The purpose of the present invention, is to overcome the phenomenon for occurring that wood resources are wasted during using pencil.This hair Bright point protector can replace pencil to hold the penholder of part, clamp pencil and be allowed to penholder itself in very short situation Under can still comply with one's wishes easily enter row write picture, pencil is fully used, eliminate caused by using pencil Wood resources wasting phenomenon.
The present invention is mainly made up of the body of rod, chuck and gripping sleeve.With chuck with being integrated, the body of rod is this to the body of rod The holding part of invention, chuck is retained part of the present invention to pencil.It is provided with chuck and gripping sleeve phase The screw thread of connection and one group of elastic clamping piece for being combined into cylindrical shape.It is combined into the elastic clamping of cylindrical shape Piece outboard end has a shape face, and inner chamber bottom is a nib support for interior truncated cone-shaped.Be provided with gripping sleeve with What penholder chuck was connected screw internal thread and it is corresponding with end stand shape face on the outside of the elastic clamping piece of chuck in Truncated cone-shaped face.
During using point protector of the present invention, the pencil that can be cut length when being as short as holding difficulty injects its cylindrical shape In elastic clamping piece, pencil stub withstands its interior truncated cone-shaped nib support, now inwardly screws gripping sleeve, gripping sleeve Interior truncated cone-shaped face will inwardly advance and oppress the platform shape face of clamp clip, cause be combined into cylindrical shape elastic clip Tight piece shrinks internal diameter and clamps pencil, and the interior truncated cone-shaped of penholder chuck inner chamber nib support also holds pencil pen naturally Head, stabilized pencil of making a concerted effort at two, reaching the holding point protector body of rod conveniently can flexibly promote short pencil in the least The goal of the invention drawn into row write is not loosened.Conversely, when outwards unscrewing its gripping sleeve, chuck loosens then can be conveniently Pencil is taken out on ground.
After realizing point protector of the present invention, the point protector body of rod can be held and conveniently flexibly promote short pencil not loose Move and drawn into row write, pencil is farthest utilized in itself, eliminated the wood caused by using pencil Material wasting of resources phenomenon.
Brief description of the drawings

Fig. 2 is the generalized section of the part of embodiment of the present invention penholder chuck 2.
Fig. 3 is the radial direction schematic cross-sectional view of the part of embodiment of the present invention penholder chuck 2 A-A ' lines along Fig. 2.
Fig. 4 is the generalized section of the part of embodiment of the present invention gripping sleeve 3.
Specific embodiment
According to diagram, the embodiment of the present invention is mainly made up of the body of rod 1, penholder chuck 2 and gripping sleeve 3.Penholder Chuck 2 is same with the body of rod 1 to be integrated.Penholder chuck 2 by be connected with gripping sleeve 3 screw thread 4, elasticity Platform shape face 7 on clamp clip 5, interior truncated cone-shaped nib support 6 and clamp clip is constituted.One group on penholder chuck 2 The mutual annular array of elastic clamping piece 5 is combined into a cylindrical shape.Gripping sleeve 3 is provided with and penholder chuck 2 Be connected screw internal thread 8 and it is corresponding with end stand shape face 7 on the outside of the elastic clamping piece with chuck 2 in Truncated cone-shaped face 9.
When needing to use point protector of the present invention, the pencil that can be cut length when being as short as holding difficulty injects its penholder It is combined into chuck 2 in the elastic clamping piece 5 of cylindrical shape, pencil stub withstands its interior truncated cone-shaped nib support 6, this The rotation screw thread 4 and the rotation screw thread 8 of gripping sleeve 3 of Shi Liyong chucks 2, inwardly screw gripping sleeve 3, clamp The interior platform shape face 9 of set will inwardly advance and oppress the platform shape face 7 of elastic clamping piece 5, causes and is combined into cylindrical shape Elastic clamping piece 5 shrink its internal diameter clamp pencil, and the interior truncated cone-shaped of the inner chamber of penholder chuck 2 nib support 6 Also pencil nib is held naturally, stabilized pencil of making a concerted effort at two, reaching the holding point protector body of rod 1 can be conveniently Short pencil is flexibly promoted not loosen the goal of the invention drawn into row write.Conversely, outwards unscrewing its gripping sleeve 3 When, chuck 2 loosens, and easily can take out pencil.
