Abstract
The utility model relates to a lengthening pencil rod which is formed by lengthening a pencil rod on a wooden carbon core pencil which is used until being shortened, and then the pencil can be used again. One end of a main pencil rod is connected with a pencil rod head sleeve, a rough type claw-shaped hand with convex points is arranged at the inner side of a pencil rod head, and the claw-shaped hand is connected with a center connecting rod. A compressible spring is sheathed on the center connecting rod, and the other head of the center connecting rod is connected with a pencil cap which can be inserted with an eraser head. A head cap is pressed by a finger, and the claw-shaped hand is extended out of the pencil head sleeve and is automatically opened under the action of tension per self. A short pencil head is put in the claw-shaped hand, the finger for pressing the pencil cap is released, and the claw-shaped hand is retracted under the action of the recovery tension of the spring. Under the action of the pencil head sleeve, the claw-shaped hand is retracted and folded, and the pencil head is griped and is retracted in the pencil head sleeve. The pencil head is not loosened in the pencil head sleeve and is integrated with the lengthening pencil rod into one body. Thus, the function of lengthening the pencil is achieved, which is convenient in use.
Description
1, technical field
The utility model relates to pencil elongated, and particularly a kind of wooden carbon pencil uses back adjunction one penholder that shortens to re-use.
2, background technology
Wooden carbon pencil on the market is indispensable a kind of writing implement such as every primary school, middle school student, university student, engineer, artist now, because of it is easy to carry, and convenient use, very popular.
But existing wooden carbon pencil, along with constantly sharpening a pencil, using, the length of pencil can shorten gradually, because pencil holder shortens, uses just to be not easy to point and has held.Short as can not to hold when writing when the length of one section remaining pencil, just have to throw away, caused no small waste like this.
3, summary of the invention
In order to solve the waste problem of using existing wooden carbon pencil to exist, for reducing waste, the utility model provides a kind of penholder, and its can extend penholder of pencil allows and uses one section penholder of pencil adjunction after shortening, is convenient to hold and uses.
A kind of pencil elongated penholder described in the utility model, end at main pen arm connects the penholder headgear, settles the claw hand who holds pencil stub in the penholder headgear, and the claw hand is connected with center-pole, overlap compressible spring on the center rod, the center rod other end connects the cap for brush that can insert the erasing rubber head.
Pencil elongated penholder of the present utility model can be by the finger pressure head cap, the compression spring, pass through center rod, the claw hand is released from the penholder headgear, and the claw hand opens automatically, puts into the short pencil head, decontrol the finger of pressing the cap for brush then, reply at spring under the effect of tension force, the claw hand catches pencil stub, retracts in the penholder headgear, short pencil and penholder are become one, the convenient use.
Pencil elongated penholder of the present utility model, hold the claw hand of pencil stub, inboard coarse shape structure for the band salient point is after the claw hand stretches out from the penholder headgear, under self tension force effect, open automatically, when the claw hand caught the pencil stub retraction, the claw hand was under the effect of pen head cover, and the claw hand shrinks, hold on pencil stub, retract to together in the penholder headgear, make pencil stub when writing, not loosening.
Pencil elongated penholder of the present utility model can use repeatedly for a long time, and is convenient, flexible, allows short pencil holder lengthening reach the purpose of twice laid, cuts the waste.
