Fig. 1 shows a preferred version of the utility model propelling pencil, wherein 1 is movable refill, the 2nd, protect and lead pipe, the 3rd, the manipulation parts of movable refill, the 4th, spring, the 5th, be fixed on the pencil eraser of the pencil other end, 5a is the pencil eraser cap that can arbitrarily take off, the 6th, the cap for brush, 6a are the spring clips that is fixed on the cap for brush.

The utility model pencil can be the wooden stick's pencil as traditional pencil, also can be propelling pencil, and propelling pencil preferably. Making in the situation of propelling pencil, this pencil forms (see figure 1) by the manipulation parts of protecting and leading pipe, movable refill and movable refill, wherein can be with or without spring, the cross section that is characterised in that the pen core of this pencil have with the standardization examination paper on answer the choice box shape and the size that are close.

The pen core cross section of the utility model pencil can be rectangle, square, ellipse or circular, but preferably rectangular.Rectangular cross section pen core hardness is 2B or HB.Said rectangular width should be close with the width of the paper answer choice box for the treatment of full-filling, is generally 08～12mm, is preferably 09～11mm, is preferably 10mm; Rectangular thickness can change in a big way, as can be 03～15mm, be preferably 05～09mm, be preferably 06～07mm.

Penholder cross section of the present utility model can be circular, oval, triangle or hexagonal, but it is preferably hexagonal, and on the outer surface of penholder, scribble the mark of any form or color, in order to show the major diameter direction of rectangle or oval pen core cross section, promptly after the screw engagement portion between pipe and penholder of protecting and leading with this pencil screwed, the major diameter of pen core was just parallel with said mark.Like this, as user during with this pencil full-filling standardization examination paper answer choice box, can hold a pen according to the direction that makes said mark towards the place ahead, this moment, the major diameter of rectangle or oval pen core was consistent with the broadside for the treatment of full-filling answer choice box just, thereby can directly start to write at an easy rate, once finish full-filling.

Be coated with or full-filling again for the ease of changing, one end of the utility model pencil can be fixed with one have by external spiral flexible up and down outside the pencil eraser of cover, this pencil eraser can become one with the cap for brush of screw fixed, and can have a spring (or elasticity) folder (referring to Fig. 1) on the said cap for brush.

Because the utility model is taken an examination close with the size and the shape of answer choice box on the shape of pencil pen core cross section or size and the standardization examination paper, need only when therefore using and once can finish full-filling, smear repeatedly the common pencil and needn't resemble, so that wasted the valuable test time, caused spiritual anxiety and flurried.Particularly making under the situation of above-mentioned propelling pencil, owing to can change pen core at any time, thus can make the examiner avoid the hardship that sharpens a pencil.In addition owing to be fixed with pencil eraser on the utility model pencil, so change answer again during full-filling use also very convenient.Test shows, uses the utility model pencil full-filling paper answer choice box, can make full-filling speed improve nearly 3 times, and not be prone to excessive, too small, the unequal defective of the full-filling that causes because of reasons such as stresses.
