Abstract
The utility model discloses a propelling pencil capable of supplying lead cores rotatablely, which comprises a pencil holder, a pencil cap and lead cores. The utility model is characterized in that a lead core fixed sheet is arranged inside the pencil holder, and the lead core fixed sheet is provided with a lead core through hole in neutral axis direction. The lower part of the lead cord fixed sheet is provided with a notch locking sheet, the lead cores are arranged in the lead core through hole, and the lower part of the lead core through hole is sheathed with a lead core supplying helical sleeve, the lower end of which is provided with a dovetail slot. The top end of the inner part of the pencil cap is crossly fixed with cutting blades. The utility model has the advantages of simple structure and convenient use, and can efficiently enhance the utilization rate of the lead cores.
Description
The utility model relates to a kind of pen, particularly a kind of rotary plumbous propelling pencil that goes out.
At present, all propelling pencils all are to press penholder top button, and the parts that unclamp the clamping lead for retractable pencil just can go out lead, and this method is normal to be produced disconnected lead and go out the uppity phenomenon of plumbous length, and the effective rate of utilization of lead for retractable pencil is reduced.Still find no at present and the same or analogous record of the utility model.
The purpose of this utility model just is to provide a kind of traditional plumbous mode that goes out that changes, and that improves the lead for retractable pencil utilization rate greatly rotaryly goes out plumbous propelling pencil.
Technical solution of the present utility model is: in the inside of penholder the lead for retractable pencil stator is set, direction is provided with the lead for retractable pencil through hole in axis, lead for retractable pencil stator upper edge, bottom on the lead for retractable pencil stator is provided with the cutting locking plate, lead for retractable pencil places the lead for retractable pencil through hole, its underpart is set with out the lead screw cover, and the lower end that goes out the lead screw cover has tongue-and-groove; The inner tip of the cap for brush is fixed with blade alternately.
Upper end at penholder is fixed with rubber; Offer observation window respectively in the both sides that are in the cap for brush of same horizontal level with blade.
The utility model is simple in structure, and modern design is easy to use; Lead for retractable pencil can adopt any hardness between the φ 1.3～2.6, and length can be isometric with penholder, and this is that other propelling pencil can't be compared, thereby has improved the effective rate of utilization of lead for retractable pencil greatly, simultaneously the utility model function of also having automatic sharpening, wiping the word of correcting mistakes.
Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.
Fig. 1 is a structure cross-sectional schematic of the present utility model;
Fig. 2～Fig. 4 is respectively upward view, front view and the left view of lead for retractable pencil stator.
With reference to accompanying drawing, the utility model is made up of penholder 2, the cap for brush 3 and lead for retractable pencil 4, the inside that is characterized in penholder 2 is provided with lead for retractable pencil stator 1, direction is provided with lead for retractable pencil through hole 11 in axis, lead for retractable pencil stator 1 upper edge, bottom on lead for retractable pencil stator 1 is provided with cutting locking plate 12, lead for retractable pencil 4 can insert the lead for retractable pencil through hole 11 from the bottom of penholder 2, and lead for retractable pencil 4 is delineated the twice holddown groove automatically through cutting locking plate 12 time, plays the fixedly effect of lead for retractable pencil; Be set with out lead screw cover 5 in the lower end of lead for retractable pencil 4, the lower end that goes out lead screw cover 5 has into two tongue-and-grooves at 180 ° of angles, goes out lead screw cover 5 and is tubular, and inwall has screw thread, and its effect is equivalent to the interior screw die in the machining.The inner tip of the cap for brush 3 is fixed with two blades 6 alternately, and the both sides that are in the cap for brush 3 of same horizontal level with blade 6 offer observation window 8 respectively; Be fixed with rubber 7 in the upper end of penholder 2.
When being ground thick or fracture, nib needs to fine away or when going out lead, put the cap for brush 3 earlier, two blades 6 were stuck in out lead screw as spanner and overlapped in the tongue-and-groove of 5 lower ends this moment, the rotation cap for brush, going out the lead screw cover rotates simultaneously, go out the lead screw cover and lead for retractable pencil is carried out mantle fiber pull it simultaneously, be sharpened when plumbous length reaches blade when lead for retractable pencil goes out, the user can see the situation of sharpening from the observation window 8 of the cap for brush.Pulling up the cap for brush after cutting can normally write, go out the lead screw cover and come off together when a lead for retractable pencil is only used remaining 1.5 centimetres of left and right sides, getting a lead for retractable pencil of taking the lead screw cover out of this moment inserts in the penholder from nib, promptly gone up holddown groove by 12 delineations of cutting locking plate, prevent lead for retractable pencil and go out the rotation simultaneously of lead screw cover, can fine away or write after inserting good lead for retractable pencil, this lead for retractable pencil length can be greater than 2 centimetres and isometric with penholder length, improved the effective rate of utilization of lead for retractable pencil greatly, this is that other propelling pencil can't be compared.
Can change with the erasing rubber of penholder upper end when writing wrongly written character.
