Abstract

The utility model discloses an automatic pencil which comprises a pencil holder, an inner core, a pencil core, an elastic element and a switching member, wherein the holder body of the pencil holder is provided with two big holes; the switching member comprises an extending press-button and a retraction press-button which are pivoted in the big holes of the pencil holder; the side wall of the inner core forms an inclined plane and also an elastic rod with a projection, the inclined plane is opposite to the extending press-button, and the elastic rod is opposite to the retraction press-button; the pencil core is sheathed in the inner core, and the front end of the pencil core is sheathed with the elastic element; the inner core is sheathed in the pencil holder; a limiting structure which can limit the reverse position of the inner core is arranged between the inner core and the pencil holder. The utility model arranges the switching member on the holder body of the pencil holder, so in operation and control, the press-buttons on the pencil holder can be directly pressed, and the operation is very convenient.

Description

A kind of from starting writing

Technical field

The utility model relates to a kind of pen, refers to a kind of from starting writing especially.

Background technology

In the prior art, the push switch of starting writing certainly is arranged on the end of pen usually, pushes once, and pen core promptly stretches out outside the penholder, pushes once again, and pen core promptly is retracted within the penholder, thereby reaches switching purposes.Yet, thisly control refill expansion from starting writing at every turn, all thumb must be retracted into the end of pen, can push, operation is convenient inadequately, so people usually forget the pen core withdrawal, causes nib to be drawn to the place that should not draw, also may damage nib.

The utility model content

The purpose of this utility model is to provide a kind of easy to operate starting writing certainly smoothly.

For achieving the above object, technical solution of the present utility model is:

A kind of from starting writing, comprise penholder, inner core, pen core, flexible member and switching member, wherein: have two large openings on the shaft of described penholder; Described switching member comprise be articulated in penholder large opening in stretch out button and the retraction button; Be formed with an inclined-plane on the sidewall of described inner core and to stretch out button relative, the elastic rod that also is formed with a band projection on it is relative with the button that bounces back; Pen core is placed in interior in-core, and its front end sleeve has elastic component, and inner core then is placed in the penholder; Between inner core and penholder, be provided with the position limiting structure that can limit its going-back position in addition.

Described position limiting structure is the little perforate that is opened on the penholder, and this little perforate is positioned at the rear of retraction button.

Described position limiting structure is the limited block that is arranged on the inner rear of penholder.

After adopting such scheme, because the utility model will be controlled the switching member that pen core stretches out and be arranged on the shaft of penholder, and control by two buttons, to realize stretching automatically to pen core, like this, when controlling, do not need thumb is retracted into the end of pen, and the button of directly pushing on the penholder gets final product, and is smoothly easy to operate.

The specific embodiment

Please as shown in Figures 1 and 2, described in the utility model starting writing certainly comprises penholder 10, inner core 20, pen core 30, flexible member 40 and switching member 50.Wherein:

Described penholder 10 hollows, its front end have the through hole 11 that the nib that can make pen core 30 is stretched out; Also have two

large openings

12,13 on the shaft of this penholder 10, the junction respectively is provided with a junction 14 between two

large openings

12,13; Also have a little perforate 15 in addition at rear side large opening 13 rears.

Described inner core 20 is placed within the penholder 10, and its structure has a groove as shown in Figure 6 on inner core 20 front end sidewalls, and this front of the slot has an inclined-plane 21; Have a through hole 22 on these inner core 20 stage casing sidewalls, be provided with the elastic rod 23 that a front end links to each other with inner core 20 in the through hole 22, because the existence of through hole 22 makes elastic rod 23 have elasticity, and the end of this elastic rod 23 is provided with a projection 23a; In inner core 20 inner bottom, be provided with a fixed leg 24 in addition.

Described pen core 30 inserts in the inner core 20, and its terminal inserting is consolidated on the fixed leg 24 of inner core 20 with fixing; The front end of pen core 30 is with a flexible member 40.

Described switching member 50 comprise stretch out button 51 and the retraction button 52; This stretches out button 51 shown in Fig. 4 A, 4B, it is arranged in the place ahead large opening 12 of penholder 10, and stretch out both sides, button 51 rear end at this and be provided with protruding axle 51a and cooperate with large opening 12 both sides forming rotatable form, other this stretch out the connecting portion 14 that button 51 rear ends also are provided with draw-in groove 51b and described large opening 12 and fasten; Stretch out button 51 upper surfaces at this and also be provided with some protruding grain 51c to increase friction; Described retraction button 52 is shown in Fig. 5 A, 5B, it is arranged in the rear large opening 13 of penholder 10, and its structure is with to stretch out button 51 similar, some protruding the 52c that also is provided with protruding axle 52a, the draw-in groove 52b that matches with the connecting portion 14 of rear large opening 13 and is provided with on upper surface.

The utility model is when combination, to stretch out button 51 and the retraction button 52 be individually fixed in the

large opening

12,13 of penholder 10, and it can be pivoted around its protruding

axle

51b, 52b, again pen core 30 is solidly plugged in the inner core 20, put flexible member 40 simultaneously, then, inner core 20 is positioned in the penholder 10, and makes its inclined-plane 21 and to stretch out button 51 relative.

The utility model as shown in Figure 2, is pushed downwards with thumb and to be stretched out button 51 in use, and its front end then presses down the inclined-plane 21 on inner core 20 sidewalls, and forces inner core 20 to move forward, thereby makes pen core 30 compression elastic elements 40 and stretch out outside the penholder 10; At this moment, the projection 23a of elastic rod 23 ends is then relative with the large opening 13 at rear on inner core 20 sidewalls, and under elastic reaction, insert into the inner, and be stuck on large opening 13 rear walls, button 52 jack-up simultaneously will bounce back, inner core 20 can't be retreated, be about to pen core 30 and be fixed on the form of stretching out outside the penholder 10.

When not re-using this and desire to make pen core 30 retraction from starting writing, as shown in Figure 3, push retraction button 52 downwards with thumb, its rear end then with the projection 23a of inner core 20 elastic rods 23 by being back in the penholder 10, like this, pen core 30 and inner core 20 are promptly under the elastic recovery effect of flexible member 40 and be retracted in the penholder 10, when the little perforate on the projection 23a of inner core 20 elastic rods 23 and the penholder 10 15 is relative, it can be under the effect of elastic force and stretches out and be stuck in this little perforate 15, make inner core 20 stop retraction, make its inclined-plane 21 and to stretch out button 51 relative, get ready for pushing next time.Certainly, also little perforate 15 can be set, and at penholder 10 inner rears one limited block be set, limit the going-back position of inner core 20 with this, when guaranteeing pen core 30 retractions, the inclined-plane 21 on inner core 20 sidewalls is with to stretch out button 51 relative.
