Abstract

The utility model relates to a propelling pencil with changeable lead cord, which changes the pen with a prior timber penholder as the pen with metal or plastic lead core protecting cover. The lead core protecting cover includes an adjusting socket, the lead core can be adjusted at random or be changed by an adjusting ring, so as the aim of saving timber, long time of using and convenience for writing can be reached.

Description

Propelling pencil
Affiliated technical field
The utility model relates to a kind of pencil of usefulness of writing, paint, and especially can freely change the pencil of lead for retractable pencil.
Background technology
At present, generally the pencil of Shi Yonging is to be made by timber parcel lead for retractable pencil, need with a large amount of timber, and remaining one section of pencil, abandon it because of holding with a firm grip, cause and waste and environmental pollution.Pencil makes dysgraphia after short, it is incorrect to form writing posture.
Summary of the invention
In order to overcome the many deficiencies of current wooden pencil consumption timber, the purpose of this utility model provides a kind of pencil, and it can not only resemble painting and calligraphy the existing pencil, and can be convenient for changing lead for retractable pencil, does not use timber, the permanent use.
The technical scheme that its technical problem that solves the utility model adopts is: in the shell of former pencil, change make material of wood as metal or plastics into, [Merlon (PC)] protects core retainer plate.Lead for retractable pencil is contained in and protects in the lead core cover, thereby has saved timber, protects lead for retractable pencil and is with a little elongated slot that is equivalent to lead core diameter 1/3rd, makes the lead for retractable pencil of all size can both be fit to be mounted in it.Protecting has a lead extrusion core adjustable ring in the lead core cover, be used for regulating lead for retractable pencil, utilizes adjustable ring, uses plumbous the author can regulate lead for retractable pencil as required.Protect lead core cover and be contained in the penholder, have the nut of V-type head to combine by one, be used for regulating clamping lead for retractable pencil with the screw thread of penholder mouth.There are two symmetrical sulculuses the upper end of protecting lead core cover, combines with two symmetrical salient points in the penholder, makes to protect lead core cover and can not rotate, and so just forms a complete pencil.
There is pencil to bore on the pen cap,, is used for the rotary cut pen core by the lead-sharpening pencil cutter that small blade is formed.
Protect the internal diameter size of the core pen cap and make according to the size of the model of lead for retractable pencil, core diameter, make it can be fit to fastening lead for retractable pencil, the upper end of lead for retractable pencil is placed with a lead extrusion core adjustable ring, and lead for retractable pencil can be regulated according to the needs that use, and is equivalent to batch wood chip position that sharpens a pencil.
The beneficial effects of the utility model are, can heavily insert replacing after lead for retractable pencil uses up, and load onto new lead for retractable pencil, and long use can be continued in other auxiliary position, has saved timber in large quantities, save user's economy spending simultaneously.
For the school-ager owing to adopted above-mentioned novel pencil,, just can once adapt to from pen, needn't walk from pencil to the conversion laundering period of using pen instead.

Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural map of utility model
Fig. 2 is the enforcement figure that protects lead core cover
Fig. 3 is a penholder threaded portion view
Fig. 4 is that lead for retractable pencil presss from both sides nearly adjusting nut figure
Fig. 5 is a lead for retractable pencil adjusting ring part drawing
Among the figure: 1, lead for retractable pencil is cut brill; 2, small blade; 3, the pen cap; 4, lead for retractable pencil presss from both sides nearly adjusting nut; 5, pen cap spacing collar; 6, penholder; 7, protect lead core cover; 8, lead for retractable pencil; 9, protect the lead core cover regulating tank; 10, lead for retractable pencil adjusting ring; 11, anti-rotation is spacing; 12, rubber is wiped.
The specific embodiment
In Fig. 1, lead for retractable pencil (8) is contained in and protects lead core cover (7) lining, with lead for retractable pencil adjusting ring (10) along protect lead core cover regulating tank (9) lead for retractable pencil (8) down pressure regulation to the position that needs of nib crack tip, the lead core cover (7) that protects of loading onto lead for retractable pencil (8) is packed in the penholder (6), protect the two prominent some interlocks mutually (11) that the lead core cover anti-rotation is spacing and penholder is interior of protecting of lead core cover (7) both sides, top, make that to protect lead core cover (7) fixing, lead for retractable pencil is pressed from both sides the thread connection of nearly adjusting nut (4) and penholder (6), by on revolve the V-type folder that protects the lead core cover front end mouthful tightened up, thereby clamp lead for retractable pencil (8).Then, use the lead for retractable pencil that matches with the pen cap (3) to cut the small blade (2) of brill (1) lining, dextrorotation is repaiied and is cut lead for retractable pencil (8), reaches the sharp degree that use needs.As write wrongly, the available rubber that is contained in penholder (6) afterbody is wiped (12) erasing and is gone.
It should be noted: the internal diameter degree that protects lead core cover (7) is consistent with the specification of lead for retractable pencil (8), and little have looseningly, and unsuitable tension is in order to avoid lead for retractable pencil adjusting ring (10) can't be regulated.Also unsuitable wide, otherwise easily broke lead for retractable pencil because of losing to fall.
The L hook of adjusting ring (10) is run into nail and is exceeded, and should not give prominence to that to protect lead core cover regulating tank (9) too much, in order to avoid hit penholder (6).Metal wire cover glue is made in the adjusting ring, and the purpose of cover glue is not allow adjusting ring arbitrarily walk about.
Be positioned at the pen cap spacing collar (5) on the penholder (6), its effect is the degree of depth of the restriction pen cap (3), avoids touching disconnected lead for retractable pencil.
