The nib sleeve assembly has the advantages that the pencil lead is clamped stably and writing is smoother.

Description

A kind of pen cap assembly of propelling pencil
Technical field
The utility model relates to a kind of stationery, especially a kind of extensible pencil, and the pencil-lead of this pencil is exempted to cut and is replaceable, and the end of pencil has can the pen cap assembly of stable holding lead for retractable pencil for writing.
Background technology
Pencil is the conventional stationery of numerous students, and common pencil in use needs continuous cutting, and nib need to often be repaiied, and cutting pen wastes time and energy, and uses inconvenient; So replaced by extensible pencil gradually.
It is lead for retractable pencil to be divided into some pencil trifles with tip be socketed up and down formation extensible pencil that extensible pencil in the market has a kind of, this pencil is owing to being that mode by upper and lower clamping is fixed, easily because connecting insecure appearance fracture, impact is write, and if the pencil of the less formation of quantity of pencil trifle is too short is inconvenient to grip.
In addition, on market, also having a kind of extensible pencil is the propelling pencil that goes out lead for retractable pencil by push type, if Chinese patent Granted publication number is the file disclosed " replaceable pencil of bullet pencil " of CN101670729 B, this replaceable pencil comprises penholder, in penholder, be provided with core storage tube, core storage tube is by core storage tube chuck clamping lead for retractable pencil, and core storage tube front end sleeve is provided with tongue spring, core storage tube front end outer wall is provided with elongated slot, on core storage tube front end outer wall, elongated slot offside is provided with short groove, short groove has larger hole near a side of core storage tube rear end and inserts butt for the tip of the tongue of tongue spring and the rear end of pencil-lead and prevent pencil-lead retraction, core storage tube rear portion is also provided with the cap for brush, the cap for brush is inserted between core storage tube outer wall and penholder inwall, be provided with the pencil-lead loading port of attached elastic bumps at core storage tube rear portion, the elastic bumps of this pencil-lead entrance guarantees that pencil-lead tip moves forward into core storage tube, stop pencil-lead tail end to move forward into core storage tube, this pencil-lead loading port can also play the lead for retractable pencil preventing in core storage tube and pours out from here simultaneously.This propelling pencil is mainly that this core storage tube chuck is better for the clamping effect of thinner lead for retractable pencil by core storage tube chuck clamping lead for retractable pencil, but not good for using the clamping effect of bullet type lead for retractable pencil of common pencil.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of good clamping effect, has write the pen cap assembly of stable propelling pencil.
To achieve these goals, the technical solution adopted in the utility model is: a kind of pen cap assembly of propelling pencil, it is characterized in that: comprise pen cap body, on described pen cap body, have the pen cap endoporus revealing for described lead for retractable pencil, in described pen cap endoporus, be embedded with the retaining sleeve that lead for retractable pencil is had to clamping action, described pen cap inner hole wall has press section, described retaining sleeve can be along the axially-movable of pen cap endoporus, and retaining sleeve has to coordinate with described press section to form and opens or the bare terminal end of folding structure, the other end that retaining sleeve has bare terminal end is relatively provided with return springs.
As further setting of the present utility model, described pen cap inner hole wall is provided with pyramidal projections, and described pyramidal projections forms described press section, and the part that described retaining sleeve is arranged in pen cap endoporus has the conical socket coordinating with described pyramidal projections of indent.
As further setting of the present utility model, the bare terminal end of described retaining sleeve is the valvular structure setting of division.
As further setting of the present utility model, the other end that described retaining sleeve has bare terminal end is relatively provided with back-moving spring, on described pen cap inner hole wall, establish bossed spring base, the other end end that described retaining sleeve has bare terminal end is relatively provided with flanging edge, described back-moving spring one end is fixedly arranged on described spring base, and the other end butt of back-moving spring described flanging edge.
Adopt such scheme, lead for retractable pencil is held cover and clamps, the tip of lead for retractable pencil is revealed in outside the end of retaining sleeve clamping lead for retractable pencil, lead for retractable pencil tail end is positioned at the bare terminal end of retaining sleeve, spring between retaining sleeve and pen cap inwall has towards the tendency of pressing piece direction motion this retaining sleeve, the conical socket of retaining sleeve outer wall is positioned at the top direction of pressing piece (towards) of taper projection, and make this bare terminal end outer wall be subject to pen cap endoporus pyramidal projections extruding and in closing up state, the action that makes to clamp lead for retractable pencil is more stable, writes more smooth, in the time that the most advanced and sophisticated change circle of this lead for retractable pencil is blunt, press pressing piece, pressing piece drives inner tube towards the extruding of pen cap direction, retaining sleeve to be squeezed, move towards pen cap direction and promote retaining sleeve, in the time that pyramidal projections falls into the conical socket of retaining sleeve outer wall, the extruding force that the bare terminal end of retaining sleeve is subject to due to its outer wall is cancelled so bare terminal end opens, lead for retractable pencil above drops and lead for retractable pencil below enters bare terminal end, unclamp pressing piece, back-moving spring on retaining sleeve resets, drive retaining sleeve to move upward and make the outer wall of bare terminal end be subject to the extruding of pyramidal projections and then clamp lead for retractable pencil.
Below in conjunction with accompanying drawing, the utility model is further described.
