Description
The utility model relates to the dual-purpose propelling pencil of a kind of double end, belongs to culture and education articles for use field.
Existing propelling pencil has only a kind of lead for retractable pencil of specification, in use, if when wanting to use the lead for retractable pencil of thickness two kinds of specifications different or that soft or hard is different respectively, then needs two propelling pencils.Therefore, frequent change-fountain pen bothers very much when writing or draw, and particularly when drawing drawing, it is more obvious that the drawback of existing singly usefulness propelling pencil shows.
At having the deficiency that propelling pencil has only a kind of lead for retractable pencil of specification now, the inventor has designed the dual-purpose propelling pencil of double end of the present utility model, and purpose is to reduce the consumption of drawing pencil, reduces the totle drilling cost of drawing pen, is convenient for people to draw or write.
The purpose of this utility model is to realize by the following technical programs:
Propelling pencil of the present utility model comprises the cap for brush, penholder, lead for retractable pencil, gum cover, spring, respectively there is a lead for retractable pencil at the two ends of pencil, lead for retractable pencil is by the center of connector, clamped by core body, core body is clamped by tapered sleeve, and nib is connected with splicing sleeve by screw thread, pole one end bearing is on connector, about the other end is bearing on two terminal adapters.
The mark overcoat that pencil specification mark and perforate are arranged on two terminal adapters about propelling pencil of the present utility model.
Fig. 1 is the sectional view of the utility model left end;
Fig. 2 is the sectional view of the utility model right-hand member;
Fig. 3 is the vertical view of the connector at the left and right two ends of the utility model.
Embodiment of the present utility model describes by accompanying drawing.
(1) is the cap for brush among the figure, can cover the two ends of pencil.Left side gum cover (2), right gum cover (18) are made by elastomeric material, and its effect is that the control lead for retractable pencil glides, control lead for retractable pencil stroke.Left side nib (3), right nib (19) are made by plastics or metal, and left side nib (3) is connected with splicing sleeve (8) by screw thread.Tapered sleeve (4) is made of metal, and clamps core body (6), and core body (6) clamps lead for retractable pencil (5) again, core body (6) is a metalwork, the effect of spring (7) is that pole (10) is resetted, and connector (9) one ends prop up on spring (7), and the other end is bearing on the pole (10).Lead for retractable pencil (5) is by the center of connector (9).(11) be penholder, pencil specification mark (12) be positioned at perforate mark overcoat (13) below, mark is marked with various hardness, the perforate of mark overcoat (13) can demonstrate thickness, the hardness of using pencil.String cover (14) can side-to-side movement under the effect of button (15), the lead for retractable pencil of pencil is stretched out or withdraws.Adapter sleeve (16) is inserted in wherein another penholder of penholder (11) and right-hand member, and two pencils are connected as a single entity.(17) be right core body, (20) are right lead for retractable pencil, and (21) are button, and other structures and the left end of right-hand member pencil are in full accord.
The utility model is on a propelling pencil, the lead for retractable pencil of two kinds of different sizes of installing is sent system, use a pen can write out the different word of stroke weight simultaneously, or the different two kind lines different of the thickness of drawing with the depth, this can use the lead for retractable pencil of two kinds of specifications to make up, one-pen can replace two pens to use, and cost is lower than two propelling pencils, and it is extremely convenient to use.
