Abstract
The invention discloses a bullet-shaped pencil lead clamping and pushing device of a propelling pencil. The device comprises a lead conveying tube communicated with a containing channel of the pencil, the side wall of the lead conveying tube is provided with an axial through groove communicated with an inner hole, the lead conveying tube is sleeved with a lead conveying sleeve, the lead conveying sleeve is provided with an elastic clamping jaw capable of extending into the axial through groove, the lead conveying sleeve can axially slide along the lead conveying tube, and the elastic clamping jaw is matched with the lead conveying sleeve in a clamping or loosening mode when axially moving in the lead conveying sleeve. The device has the advantages of being reliable in structure and reasonable in design, and enabling a bullet-shaped pencil lead in the containing channel to stably move in the containing channel and smoothly come out.
Description
Technical field
The present invention relates to a kind of stationery, especially a kind of extensible pencil, the pencil-lead of this pencil is exempted to cut and is replaceable.
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 with the extensible pencil of sub warhead lead for retractable pencil gradually.
It is sub warhead lead for retractable pencil to be divided into some pencil trifles with tip be socketed up and down formation extensible pencil that sub warhead 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 sub warhead pencil is by push type, to go out the propelling pencil of sub warhead lead for retractable pencil, if Chinese patent Granted publication number is the replaceable pencil > > of the disclosed < < of the file bullet pencil of CN101670729 B, this replaceable pencil comprises penholder, in penholder, be provided with core storage tube, 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 for the tip of the tongue of tongue spring, inserts butt and the rear end of pencil-lead and prevent pencil-lead retraction, when pressing piece promotes core storage tube, the tongue of spring is stirred pencil-lead, realize the replacement one by one of pencil-lead, yet, realize pencil-lead replacement and need to promote core storage tube through longer stroke, if sub warhead lead for retractable pencil does not clamp and advances through clamping device in this process, its motion process is unstable, easily in holding channel, swing, when it arrives pen cap, knockout meeting has some setbacks.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of clamping propulsion plant of sub warhead lead for retractable pencil of the propelling pencil that can make the sub warhead lead for retractable pencil stable motion in holding channel in holding channel, smooth and easy knockout.
To achieve these goals, the technical solution used in the present invention is: a kind of sub warhead lead for retractable pencil clamping propulsion plant of propelling pencil, it is characterized in that: comprise with the holding channel of pencil connects and send core pipe, send core pipe sidewall to be provided with the axial pass trough communicating with endoporus, send core pipe to be arranged with outward and send core retainer plate, the elasticity jaw that send core retainer plate to be provided with can to stretch in described axial pass trough, the described core retainer plate that send can be along sending core pipe axial slip, and described elasticity jaw forms clamping or unclamps matching relationship in the process of sending core retainer plate to axially move.
In said structure, when sub warhead lead for retractable pencil enters from unidirectional that core passage enters holding channel until while sending the axial elongated slot position of core pipe, be arranged in the elasticity jaw of core retainer plate by sending core retainer plate that send sending on core pipe and draw in and prop up the tail end of sub warhead lead for retractable pencil at axial elongated slot, and towards pen cap, carry under the driving of pressing piece.
As the further setting of the present invention, the described core pipe that send is arranged with gripping sleeve outward, gripping sleeve inwall with send the axial pass trough corresponding section of core pipe to be provided with flange, described flange surrounds elasticity jaw on can feed core retainer plate at the bore that stretches into or exit when sending core pipe axial slip.
In said structure, owing to sending the elasticity jaw of core retainer plate, it is plastic material, use after certain hour, easily there is phenomenon aging and that exist elasticity jaw to close up, under the situation that the setting of above-mentioned gripping sleeve cannot be closed up automatically at elasticity jaw, flange by gripping sleeve inwall closes up elasticity jaw to the extruding of elasticity jaw, has extended the service life of pencil.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Accompanying drawing 1 is the structure cutaway view of specific embodiment of the invention propelling pencil;
Accompanying drawing 2 is the structure cutaway view of the another kind of pencil of the specific embodiment of the invention;
Accompanying drawing 3 is specific embodiment of the invention inner tube and the structural representation that send core pipe;
Accompanying drawing 4 is that the specific embodiment of the invention is with the structure cutaway view of the pencil of gripping sleeve.
The specific embodiment
Specific embodiments of the invention are the sub warhead lead for retractable pencil clamping propulsion plant of propelling pencil as Figure 1-4, what comprise that holding channel 4 with pencil connects send core pipe 41, send core pipe 41 sidewalls to be provided with and the axial pass trough 411 that send core pipe orifice to communicate, send outer being arranged with of core pipe 41 to send core retainer plate 5, the elasticity jaw 51 that send core retainer plate 5 to be provided with can to stretch in axial pass trough 41, send the core retainer plate 51 can be along sending core pipe 41 axial slips, elasticity jaw 51 forms and clamps or unclamp matching relationship in the process of sending core retainer plate 10 to axially move.
In said structure, when sub warhead lead for retractable pencil enters from pencil unidirectional, core passage enters holding channel 4 until while sending axial elongated slot 411 position of core pipe 41, be arranged in the elasticity jaw 51 of core retainer plate 5 by sending core retainer plate 5 that send sending on core pipe 41 and draw in and prop up the tail end of sub warhead lead for retractable pencil at axial elongated slot 41, and towards pen cap, carry under the driving of pressing piece.
The above-mentioned core pipe 41 that send is arranged with gripping sleeve 52 outward, gripping sleeve 52 inwalls with send axial pass trough 411 corresponding sections of core pipe 41 to be provided with flange 521, flange 521 surrounds elasticity jaw 51 on can feed core retainer plate 5 at the bore that stretches into or exit when sending core pipe 41 axial slip.
In said structure, owing to sending the elasticity jaw 51 of core retainer plate 5, are plastic materials, use after certain hour, easily there is phenomenon aging and that exist elasticity jaw 51 to close up, under the situation that the setting of above-mentioned gripping sleeve 52 cannot be closed up automatically at elasticity jaw 51, the extruding of the 521 pairs of elasticity jaws 51 of flange by gripping sleeve 52 inwalls is closed up elasticity jaw 52, has extended the service life of pencil.
The present invention have advantages of reliable in structure, reasonable in design, can make the sub warhead lead for retractable pencil stable motion in holding channel in holding channel, smooth and easy knockout.
