Abstract
The utility model relates to stationery, specifically is an automatic eraser pencil. In order to solve the problem that the existing drawing eraser can not conveniently erase the position of pencil lines which are difficult to erase, the utility model provides the automatic eraser pencil which comprises a pencil point, a pencil sleeve which is provided with a clamping groove, a propulsion device and a clamp. The propulsion device is arranged in the pencil sleeve, and the front end of the propulsion device is provided with an eraser hole. The back end of the propulsion unit is provided with a clamp fixing hole, and the clamp is matched with the propulsion device by a hole shaft together. The eraser is adopted as a core of the automatic eraser pencil of the utility model and can conveniently erase the position of pencil line traces which are difficult erased. At the same time, the eraser is fixed by a locking device and the utility model can be used for erasing large area of writing and can also fix a pencil by the locking device. In this way, the fixation of the pencil and the eraser is realized and the utility model has the advantage of convenient and quick operation.
Description
Technical field
The utility model relates to a kind of stationery, specifically is a kind of Automatic rubber pencil.
Background technology
In with the pencil drawing course, always to wipe some lines person's handwritings with drawing eraser because of revising, since drawing eraser more greatly, thicker, when to two adjacent nearer lines, wipe wherein one, be difficult to not have influence on the definition of another lines, it is just difficult more to wipe some tiny lines, round dot, the part that is easy to wipe is also wiped, so that the picture of having to mend again, and then influences operating efficiency.
Summary of the invention
The utility model can't be wiped the problem that is difficult for wiping position pencil lines easily in order to solve existing drawing eraser, and a kind of Automatic rubber pencil is provided.
The utility model is to adopt following technical scheme to realize: a kind of Automatic rubber pencil, comprise nib, be provided with the pen cap, propulsion plant, the clamp of draw-in groove, propulsion plant is arranged in the pen cap, the front end of propulsion plant is provided with the rubber hole, the rear end of propulsion plant is provided with the clamp fixing hole, and clamp and propulsion plant are combined together by the hole axle.During use, eraser core is passed nib to be inserted in the propulsion plant rubber in front hole, clamp is extracted out along its axis direction, make eraser core suitably expose nib along the mobile forward or backward propulsion plant of the axis direction of the pen cap, again clamp is back in the draw-in groove of the pen cap, fixedly propulsion plant has been finished moving of eraser core.
The rear end of the pen cap also is fixed with locking device by screw thread.Locking device is made of nut and main body, and main body is provided with 4 fixed arms, and there is screw thread in the fixed arm outside, and the thickness of fixed arm increases from inside to outside gradually.Fixed arm can clamp rubber or pencil when nut screws, and has realized the fixing of rubber and pencil.
It is core that Automatic rubber pencil described in the utility model adopts rubber, can wipe the pencil stitching that is difficult for wiping the position easily; Simultaneously, adopt fixedly rubber of locking device, can be used for wiping of large tracts of land person's handwriting, also available locking device is pencil fixedly, has realized the fixing, easy to use of pencil and rubber, and is quick.

The specific embodiment
A kind of Automatic rubber pencil, comprise nib 3, be provided with the pen cap 2, propulsion plant 7, the clamp 5 of draw-in groove, propulsion plant 7 is arranged in the pen cap 2, and the front end of propulsion plant 7 is provided with the rubber hole, the rear end of propulsion plant 7 is provided with the clamp fixing hole, and clamp 5 and propulsion plant 7 are combined together by the hole axle.During use, eraser core 6 is passed nib 3 to be inserted in the propulsion plant 7 rubber in front holes, clamp 5 is extracted out along its axis direction, make eraser core 6 suitably expose nib 3 along the mobile forward or backward propulsion plant 7 of the axis direction of the pen cap 2, clamp 5 is back in the draw-in groove of the pen cap 2, fixedly propulsion plant 7 again.Fine eraser core can be wiped the pencil lines that are difficult for wiping the position easily.
The rear end of the pen cap 2 is fixed with locking device by screw thread.Locking device is made of nut 1 and main body 4, and main body 4 is provided with 4 fixed arms, and there is screw thread in the fixed arm outside, and the thickness of fixed arm increases from inside to outside gradually.Fixed arm can clamp rubber when nut 1 screws.Be used for fixing relatively large rubber, realize wiping of large tracts of land person's handwriting.During use, the nut of locking device is unscrewed, rubber is inserted between the fixed arm of main body, again nut screwing clamping, the realization rubber is fixed.Can also replace rubber with pencil, the rubber pen is fixed on the pencil.
Draw-in groove on the pen cap 2 can be made into circle, square, leg-of-mutton zigzag, and the stiff end shape of clamp 5 needs the form fit with draw-in groove.In this specific embodiment, the draw-in groove on the pen cap 2 is the triangle zigzag.
Nib 3 is by the fixing front end of the pen cap 2 of screw thread, and in this specific embodiment, for better protection eraser core 6 is not fractureed, the head of nib 3 has been whittled into the inclined-plane.
