Abstract
The utility model relates to a propelling pencil with a rotating lead. The propelling pencil comprises a pencil rod, a conical pencil point cap, a pencil tube and a press cap. The pencil point cap is mounted below the pencil rod, the press cap is mounted on the pencil tube, a sliding groove is formed in the pencil point cap, and a rubber block is mounted below the pencil tube. A tapered hole is formed in the rubber block, and the outer diameter of the tapered hole is larger than the diameter of the sliding groove. The rubber block is slidably mounted in the sliding groove. A spring is sleeved on the pencil tube. The lower end of the spring is abutted against the upper end of the sliding groove. A rotating column is rotationally mounted above the pencil rod. A clockwork spring is mounted in the pencil rod. One end of the clockwork spring is fixed on the rotating column, and the other end of the clockwork spring is fixed on the pencil tube. The clockwork spring is tightened through rotation of the rotating column before writing, and slowly releases action force to push the pencil tube to rotate in the pencil rod during writing, so that the lead continuously and axially rotates during writing, the end face of the lead wears evenly, eccentric wear is avoided, and thicknesses of writing lines are kept uniform.
Description
Technical field
The utility model relates to a kind of stationery, is specifically related to a kind of propelling pencil.
Background technology
As everyone knows, propelling pencil when writing because nib and paper are that heeling condition is write, thereby nib place end face can be write wider and wider, thereby cause the word lines width of writing to differ.
Summary of the invention
The utility model is in order to overcome the deficiency of above technology, provides a kind of pen core can be with the pen core rotating propelling pencil of writing process rotation.
The utility model overcomes the technical scheme that its technical problem adopts:
This pen core rotating propelling pencil, comprise penholder, be installed on the conical written cap of penholder below, the shaft of a writing brush, be installed on the pressure cap on the shaft of a writing brush, described written cap inside is provided with chute, described shaft of a writing brush below is provided with block rubber, described block rubber inside is provided with the diameter that its external diameter of taper hole is greater than chute, described block rubber is slidably mounted in chute, on the described shaft of a writing brush, be set with spring, the lower end abutment of described spring is in the upper end of chute, described penholder top is rotatablely equipped with column spinner, penholder inside is provided with clockwork spring, one end of described clockwork spring is fixed on its other end on column spinner and is fixed on the shaft of a writing brush.
In order to improve support strength, also comprise the gripper shoe being arranged in penholder, the described shaft of a writing brush is rotatably installed in gripper shoe.
The beneficial effects of the utility model are: before writing, by rotation column spinner, tighten clockwork spring, afterwards in writing process, the slow release action of clockwork spring is tried hard to recommend the pipe of starting writing and is rotated in penholder, thereby realize the continuous axial rotation of lead for retractable pencil when writing, thereby make its end wear evenly there will not be eccentric wear phenomenon, the line weight of writing is consistent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1. written cap 9. chute 10. block rubber 11. springs of penholder 2. column spinner 3. shaft of a writing brush 4. pressure cap 5. clockwork spring 6. lead for retractable pencil 7. gripper shoe 8..
The specific embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
This pen core rotating propelling pencil, comprise penholder 1, be installed on the conical written cap 8 of penholder 1 below, the shaft of a writing brush 3, be installed on the pressure cap 4 on the shaft of a writing brush 3, described written cap 8 inside are provided with chute 9, the described shaft of a writing brush 3 belows are provided with block rubber 10, described block rubber 10 inside are provided with the diameter that its external diameter of taper hole is greater than chute 9, described block rubber 10 is slidably mounted in chute 9, on the described shaft of a writing brush 3, be set with spring 11, the lower end abutment of described spring 11 is in the upper end of chute 9, described penholder 1 top is rotatablely equipped with column spinner 2, penholder 1 inside is provided with clockwork spring 5, one end of described clockwork spring 5 is fixed on its other end on column spinner 2 and is fixed on the shaft of a writing brush 3.By pressing pressure cap 4, drive the shaft of a writing brush 3 to move down, and Compress Spring 11 makes block rubber 10 skid off chute 9 can to make block rubber 10 not receive the lead for retractable pencil 6 of extruding in the shaft of a writing brush 3 can to skid off after partial-length under Action of Gravity Field, finger is no longer exerted pressure to pressure cap 4, under spring 11 elastic force, drive the shaft of a writing brush 3 to drive block rubber 10 to slip in chute 9, because block rubber 10 external diameters are large, therefore chute 9 extruding block rubber 10 distortion, fix it thereby the taper hole in it can pin lead for retractable pencil 6.Before writing, by rotation column spinner 2, tighten clockwork spring 5, afterwards in writing process, pipe 3 rotation in penholder 1 of starting writing is tried hard to recommend in the slow release action of clockwork spring 5, thereby realize the continuous axial rotation of lead for retractable pencil 6 when writing, thereby make its end wear evenly there will not be eccentric wear phenomenon, the line weight of writing is consistent.
Also comprise the gripper shoe 7 being arranged in penholder 1, the described shaft of a writing brush 3 is rotatably installed in gripper shoe 7.Gripper shoe 7 can improve the intensity of the shaft of a writing brush 3, prevents that it is out of shape in pressing or rotating, and has improved service life.
