Description

New type auto pen

Technical field:

The utility model relates to a kind of pen, particularly a kind of flexible automatically pen.

Background technology:

At present, as putting one-pen as last, use for messenger at mechanism's windows such as bank, administrative services, but situation is so mostly: people use up a back bulk storage on table top, Pen Association's leakage of oil, the table top fleckiness of lane, also can make dirty because of carelessness coat-sleeve and so easy damage nib.

Summary of the invention:

The utility model provides a kind of new type auto pen, and in the automatic indentation penholder of pen core meeting, in case hold the first stroke of a Chinese character, pen core just can be stretched again when this was no.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of new type auto pen, form by penholder (1), inner pen tube (2), rubber sleeve (3).Rubber sleeve is placed in the position that penholder holds a pen, and there is the cavity at the position that holds a pen of penholder, and the rubber sleeve inwall has outer projection (5), is just passing the cavity; Outer projection is the inverted triangle body, and its inclined-plane is a concave arc; The inner pen tube outer wall has interior projection (4), and interior projection is triangle body, and its inclined-plane is a convex arc.Outer projection staggers relative with interior projection; There are corner angle one termination of inner pen tube, is stuck in penholder and movable.The other end headgear of inner pen tube has elastic component, and is placed in the penholder restraining position ring block in the penholder, the motion of restriction flexible member again.

The beneficial effects of the utility model are: simple and reasonable, convenient and practical, the shatter-resistant pen core provides a kind of kind of novelty again for a market.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the sectional view of outer projection (5).

Fig. 3 is the sectional view of interior projection (4).

1. penholders among the figure, 2. inner pen tube, 3. rubber sleeve, 4. in projection, 5. outer projection, 6. flexible member.

The specific embodiment

In the drawings, form new type auto pen by penholder (1), inner pen tube (2), rubber sleeve (3).Rubber sleeve (3) is placed in the position that penholder holds a pen, and there is the cavity at the position that holds a pen of penholder, and the rubber sleeve inwall has outer projection (5), is just passing the cavity; Outer projection is the inverted triangle body, and its inclined-plane is a concave arc; The inner pen tube outer wall has interior projection (4), and interior projection is triangle body, and its inclined-plane is a convex arc.Outer projection staggers relative with interior projection; There are corner angle one termination of inner pen tube, is stuck in penholder and movable.The other end headgear of inner pen tube has elastic component (6), is placed in the penholder restraining position ring block in the penholder, restriction flexible member (6) motion again.Install pen core to inner pen tube, when external force acts on rubber sleeve (3), outer projection (5) is pressed to interior projection (4), promotes inner pen tube (2) and moves down, and nib comes out; Remove external force again, rubber sleeve (3) recovers shape, under the effect of flexible member (6) bounce-back, and the nib withdrawal.

Claims (3)
