Abstract
A push rod type lead-adjustable pencil comprises a pencil holder, a lead is arranged inside the pencil holder, an elastic clamp sleeve is sealed at the bottom end of the pencil holder, the lead is tightly engaged with the clamp sleeve and penetrates through the same, a clamp cap is arranged at the top end of the pencil holder, an elastic body capable of driving a lead adjusting rod to move downwards rather than move upwards is arranged at the bottom end of the clamp cap, a hole in which the lead adjusting rod can be pressed is arranged on the elastic body, and the lead adjusting rod is in abutting engagement with the top end of the lead. The lead can move downwards by pressing the lead adjusting rod, the downwards moving distance can be set according to needs of customers, therefore, the push rod type lead-adjustable pencil is simple in operation and fine in using effect. Besides, the bottom end of the clamp cap is provided with the elastic body of an inverted conical structure, the elastic body is provided with the hole in which the lead adjusting rod can be pressed, the periphery of the elastic body corresponding to the hole is provided with notches which limit the lead adjustingrod to move downwards rather than move upwards, thereby achieving more reasonable structure.
Description
(1) technical field
The utility model relates to a kind of pencil of adjustable core.
(2) background technology
Except common Wood pencil, pulsating and knock type propelling pencil are also arranged in the market, the length of the each downward modulation of these propelling pencils is fixed, and can't regulate control according to client's actual needs, uses inconvenience.
(3) summary of the invention
In order to solve the problem that above-mentioned propelling pencil exists, the utility model provides a kind of push-down of energy automatic setting lead for retractable pencil downward modulation length to transfer pencil.
For this reason, the utility model is taked following technical scheme:
A kind of push-down is transferred pencil, includes the penholder of built-in lead for retractable pencil, and the flexible cutting ferrule of bottom shutoff of described penholder, lead for retractable pencil and cutting ferrule closely cooperate and run through described cutting ferrule; The top of described penholder is provided with the card cap, described card cap bottom be provided with make transfer core bar can only move down can not on the elastomer that moves, described elastomer be provided with for transfer core bar press into the hole; Described accent core bar offsets with the lead for retractable pencil top and cooperates.
Also include standby accent core bar.
Described elastomer is an inverted cone-shaped structure, and described elastomer is furnished with otch along the hole one-week interval.
Employing the utlity model has following advantage: 1, realize moving down of lead for retractable pencil by following the pressing of transferring core bar, moving down random length can set according to client's needs, simple to operate, result of use good; 2, card cap bottom is provided with the elastomer of inverted cone-shaped structure, elastomer be provided with for transfer core bar press into the hole, be provided with otch around the elastomer corresponding aperture, limited the accent core bar can only move down can not on move more reasonable structure; 3, have accent core bar different in size, transfer core bar available metal silk or bamboo let to make, the user also can make by oneself, and is very convenient feasible; 4, in addition; the lead for retractable pencil of propelling pencil in the market is too thin; general diameter is 0.5mm-0.7mm; the stressed lead for retractable pencil that will fracture of its lead for retractable pencil of concentration point a little during use; and the pencil lead diameter of this structure can be designed to and the on all four diameter of traditional Wood-bar pencil all size lead for retractable pencil, and not frangibility, and accessory can adopt plastics or metal; can save a large amount of very deficient high-quality timber at present, significant to preserving the ecological environment.
(4) description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
(5) specific embodiment
With reference to Fig. 1, a kind of push-down is transferred pencil, includes the penholder 4 of built-in lead for retractable pencil 3, and the flexible cutting ferrule 5 of the bottom shutoff of described penholder, lead for retractable pencil and cutting ferrule closely cooperate and run through described cutting ferrule; The top of described penholder is provided with card cap 1, described card cap bottom be provided with make transfer core bar 2 can only move down can not on the elastomer 11 that moves, described elastomer be provided with for transfer core bar press into hole 12; Described accent core bar offsets with the lead for retractable pencil top and cooperates.Also include standby accent core bar.Described elastomer is an inverted cone-shaped structure, and described elastomer is furnished with otch along the hole one-week interval.
Operation principle of the present utility model is: when lead for retractable pencil after the endoporus of cutting ferrule pushes, the top of lead for retractable pencil is blocked cap and is propped up and can use.The elastic ferrule endoporus is that the zero clearance cooperates with lead for retractable pencil, so lead for retractable pencil can not glide automatically.When in using, needing to adjust lead for retractable pencil and moving down length, can will transfer core bar to press in the card cap hole that is installed in the penholder top, the end opening of card cap is made the elastomer of inverted cone-shaped structure, elastomer be provided with for transfer core bar press into the hole, be provided with otch around the elastomer corresponding aperture, enter the back transfer core bar can not on push away, thereby make the use length of lead for retractable pencil obtain adjusting.
Claims (3)
1, a kind of push-down is transferred pencil, includes the penholder of built-in lead for retractable pencil, and it is characterized in that: the flexible cutting ferrule of bottom shutoff of described penholder, lead for retractable pencil and cutting ferrule closely cooperate and run through described cutting ferrule; The top of described penholder is provided with the card cap, described card cap bottom be provided with make transfer core bar can only move down can not on the elastomer that moves, described elastomer be provided with for transfer core bar press into the hole;
Described accent core bar offsets with the lead for retractable pencil top and cooperates.
2, push-down as claimed in claim 1 is transferred pencil, it is characterized in that: also include standby accent core bar.
