Abstract
The utility model discloses a kind of sub warhead lead for retractable pencil clamping propulsion plant of propelling pencil, comprise and throughly with the holding channel of pencil send core pipe, core pipe sidewall is sent to be provided with the axial pass trough communicated with endoporus, send to be arranged with outside core pipe and send core retainer plate, send core retainer plate to be provided with can to stretch into the elasticity jaw in axial pass trough, send core retainer plate can along sending core pipe axial slip, elasticity jaw forms clamping or unclamps matching relationship in the process sending core retainer plate to axially move.The utility model have structure reliable, reasonable in design, can make the sub warhead lead for retractable pencil stable motion in holding channel in holding channel, smooth and easy knockout advantage.
Description
Technical field
The utility model relates to a kind of stationery, especially a kind of extensible pencil, and the pencil-lead of this pencil exempts to cut and replaceable.
Background technology
Pencil is the stationery that numerous students commonly use, and common pencil in use needs continuous cutting, and nib needs often to repair, and cutting pen wastes time and energy, and uses inconvenience; So gradually replace by the extensible pencil with sub warhead lead for retractable pencil.
It is that pencil trifle sub warhead lead for retractable pencil being divided into some band tips is socketed formation extensible pencil up and down that sub warhead pencil in the market has a kind of, this pencil is owing to being fixed by the mode of upper and lower clamping, easily affect because connecting insecure appearances fracture and write, and if the pencil of the less formation of the quantity of pencil trifle is too short is inconvenient to grip.
In addition, market also have a kind of sub warhead pencil to be the propelling pencil being gone out sub warhead lead for retractable pencil by push type, if Chinese patent Authorization Notice No. is " replaceable pencil of bullet pencil " disclosed in the file of CN101670729 B, this replaceable pencil comprises penholder, core storage tube is provided with in penholder, core storage tube front end sleeve is provided with tongue spring, core storage tube front end outer wall is provided with elongated slot, on the outer wall of core storage tube front end, elongated slot offside is provided with short groove, short groove has larger hole and inserts for the tip of the tongue of tongue spring the rear end that abut pencil-lead and prevent pencil-lead from bouncing back near the side of core storage tube rear end, when pressing piece promotes core storage tube, the tongue of spring stirs pencil-lead, realize the replacement one by one of pencil-lead, but, realize pencil-lead to replace and need to promote core storage tube through comparatively Long travel, if sub warhead lead for retractable pencil does not carry out clamping through clamping device and advances in this process, then its motion process is unstable, easily swing in holding channel, then when it arrives pen cap, knockout can have some setbacks.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of clamping propulsion plant of sub warhead lead for retractable pencil of 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 adopted in the utility model is: a kind of sub warhead lead for retractable pencil clamping propulsion plant of propelling pencil, it is characterized in that: comprise and throughly with the holding channel of pencil send core pipe, core pipe sidewall is sent to be provided with the axial pass trough communicated with endoporus, send to be arranged with outside core pipe and send core retainer plate, send core retainer plate to be provided with can to stretch into the elasticity jaw in described axial pass trough, the described core retainer plate that send can along sending core pipe axial slip, and described elasticity jaw forms clamping or unclamps matching relationship in the process sending core retainer plate to axially move.
In said structure, when sub warhead lead for retractable pencil from unidirectional enter core passage enter holding channel until when sending the axial elongated slot position of core pipe, be arranged in and send the core retainer plate that send on core pipe to pass through to send the elasticity jaw of core retainer plate to draw the tail end propping up sub warhead lead for retractable pencil at axial elongated slot, and carry towards pen cap under the driving of pressing piece.
As further setting of the present utility model, described sending outside core pipe is arranged with gripping sleeve, gripping sleeve inwall with send the axial pass trough corresponding section of core pipe to be provided with flange, described flange surround can elasticity jaw on feed core retainer plate along with sending the bore stretching into or exit during core pipe axial slip.
In said structure, because the elasticity jaw sending core retainer plate is plastic material, after using certain hour, easy appearance is aging and there is the phenomenon that elasticity jaw cannot close up, under the situation that the setting of above-mentioned gripping sleeve then cannot be closed up automatically at elasticity jaw, by the flange of gripping sleeve inwall, elasticity jaws close is made to the extruding of elasticity jaw, extend the service life of pencil.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Accompanying drawing 1 is the structure sectional view of the utility model specific embodiment propelling pencil;
Accompanying drawing 2 is the structure sectional view of the another kind of pencil of the utility model specific embodiment;
Accompanying drawing 3 is the structural representation managing and send core pipe in the utility model specific embodiment;
Accompanying drawing 4 is the structure sectional view of the utility model specific embodiment with the pencil of gripping sleeve.
Detailed description of the invention
Specific embodiment of the utility model is the sub warhead lead for retractable pencil clamping propulsion plant of propelling pencil as Figure 1-4, comprise and throughly with the holding channel 4 of pencil send core pipe 41, core pipe 41 sidewall is sent to be provided with and the axial pass trough 411 sending core pipe orifice to communicate, send to be arranged with outside core pipe 41 and send core retainer plate 5, send core retainer plate 5 to be provided with can to stretch into the elasticity jaw 51 in axial pass trough 41, send core retainer plate 51 can along sending core pipe 41 axial slip, elasticity jaw 51 forms clamping or unclamps matching relationship in the process sending core retainer plate 10 to axially move.
In said structure, when sub warhead lead for retractable pencil from pencil unidirectional enter core passage enter holding channel 4 until when sending axial elongated slot 411 position of core pipe 41, be arranged in and send the core retainer plate 5 that send on core pipe 41 to draw by sending the elasticity jaw 51 of core retainer plate 5 tail end propping up sub warhead lead for retractable pencil at axial elongated slot 41, and carry towards pen cap under the driving of pressing piece.
Above-mentioned sending outside core pipe 41 is arranged with gripping sleeve 52, gripping sleeve 52 inwall with send axial pass trough 411 corresponding section of core pipe 41 to be provided with flange 521, flange 521 surround can elasticity jaw 51 on feed core retainer plate 5 along with sending the bore stretching into or exit during core pipe 41 axial slip.
In said structure, because the elasticity jaw 51 sending core retainer plate 5 is plastic materials, after using certain hour, easy appearance is aging and there is the phenomenon that elasticity jaw 51 cannot close up, under the situation that the setting of above-mentioned gripping sleeve 52 then cannot be closed up automatically at elasticity jaw 51, by the extruding of flange 521 pairs of elasticity jaws 51 of gripping sleeve 52 inwall, elasticity jaw 52 is closed up, extend the service life of pencil.
The utility model have structure reliable, reasonable in design, can make the sub warhead lead for retractable pencil stable motion in holding channel in holding channel, smooth and easy knockout advantage.
