The utility model discloses simple structure, cover can effectively prevent that the lead from breaking after on the pencil, but a position and can be held according to the rubber pad quickly determine of tip under the tip of the brushstyle of a writing or painting to the make full use of pencil stub, are convenient for to form the good pen custom of holding.

Description

A kind of point protector

Technical field

The utility model is related to a kind of stationery, more particularly, to a kind of point protector.

Background technology

Pencil is the indispensable stationery that learns and handle official business.At present conventional pencil is mostly cylindric, is using Fall sometimes in journey on the ground, not only break nib, and break the pen core of the inside, and affect the use of follow-up pencil, cause Greatly waste.Simultaneously after pencil uses into very short nib, it is difficult to grasp use, it is typically only capable to discard pencil stub, Cause the wasting of resources.

Additionally, there are many people's pen holding postures incorrect, hold a pen too on the lower or too top, more just begun to use lead The child of pen, is difficult to grasp pen griping position and affect to write, or forms the bad custom that holds a pen.

Utility model content

The purpose of this utility model is to solve easily to break pen core especially internal pen core during pencil use, and pencil is used Cannot grasp into after nib and writing process in pen griping position be difficult determine problem, there is provided a kind of point protector, the point protector Simple structure, can effectively prevent pencil-lead from breaking after being enclosed within pencil, can make full use of pencil stub, and can quickly determine and hold a pen Position, is easy to form the good custom that holds a pen.

The utility model is in order to solve the above problems using following scheme：

A kind of point protector, including the shaft of a writing brush that upper and lower ends are open, the bottom and top of the shaft of a writing brush/upper end difference Resilient rubbber cushion is provided with, the rubber blanket is sleeved on the shaft of a writing brush, and it is shaped as annular shape.

The shaft of a writing brush upper end is provided with a rubber case that can load rubber, is threadedly coupled between rubber case and the shaft of a writing brush or grafting Formula connects.

The annulus periphery of the resilient rubbber cushion is provided with a stop surfaces.

One or more longitudinal openings are provided with the shaft of a writing brush.

Flexible projection on the inwall of the shaft of a writing brush, used as a kind of preferred structure, elastic bumps are wedge shape, by shaft of a writing brush inwall Progressively become from top to bottom big

Slipmat or anti-slip veins are provided with the outer wall of the shaft of a writing brush bottom.

The beneficial effects of the utility model are to arrange resilient rubbber cushion at the two ends of the shaft of a writing brush of point protector, and point protector is in lead The outside of pen, when pencil is dropped, two resilient rubbber cushions can prevent breaking for internal pen core, to a great extent can also Solve the problems, such as that nib was broken.Be located at simultaneously the resilient rubbber cushion of the point protector shaft of a writing brush lower end finger for grasping pen is had one it is spacing Effect, can accordingly judge pen griping position, form the good custom that holds a pen.What is held in writing process is the sleeve pipe of point protector, and Non-immediate grasping pencil, pencil does not affect normally to use after shortening, and so as to solve the problems, such as that pencil stub cannot be used, improves The utilization rate of pencil, is conducive to energy-conserving and environment-protective.

Specific embodiment

Embodiment 1

As shown in figure 1, point protector in the present embodiment, including the shaft of a writing brush 2 that upper and lower ends are open, pencil 11 is sleeved on the shaft of a writing brush In 2, when pencil is longer, the top of pencil can expose from one end of point protector, cover respectively in the bottom and upper end of the shaft of a writing brush Equipped with resilient rubbber cushion, bottom for lower rubber blanket 1, upper end for upper rubber blanket 3.The part of the shaft of a writing brush 2 of point protector without It is oversize, as long as the shaft of a writing brush 2 between lower rubber blanket 1 and upper rubber blanket 3 conveniently holds a pen.During the insertion shaft of a writing brush 2 of pencil 11, nib is adjusted With the distance between lower rubber blanket 1, when the finger for grasping pen is in lower rubber blanket 1, pen griping position is suitable.

It is shaped as annular shape to resilient rubbber cushion, as shown in fig. 7, resilient rubbber cushion is fixed on into the shaft of a writing brush 2 by centre bore 9 On.As a kind of preferred embodiment, a stop surfaces 10 are provided with the annulus periphery of resilient rubbber cushion, as shown in Figure 8.Using The structure of stop surfaces, when pen is placed on into desktop, stop surfaces 10 are contacted with desktop rather than periphery is contacted with desktop, and pen is difficult Roll down from desktop.In pen from after being higher by and fall, due to the presence of stop surfaces 10 during rolling, can quickly stop rolling.

The shaft of a writing brush 2 can be with as shown in figure 3, be provided with a longitudinal opening 6, the longitudinal opening 6 can run through the upper and lower of the shaft of a writing brush 2 Two ends.Also can multiple longitudinal openings 6 be set on the shaft of a writing brush 2, referring to Fig. 4.When multiple longitudinal openings are set, have in shaft of a writing brush upper end A part of imperforation, is hollow out in the middle of the shaft of a writing brush 2.The purpose for arranging longitudinal opening 6 is to ensure that the shaft of a writing brush 2 has certain shrinkage, In the Convenient pencil insertion shaft of a writing brush 2.

The place of holding a pen of the shaft of a writing brush 2 is provided with slipmat 8, slipmat 8 can be made with rubber etc..Or directly in the shaft of a writing brush 2 Or anti-slip veins are set on the whole shaft of a writing brush, and the skidding that holds a pen after perspiring is prevented, strengthen the comfortableness for holding a pen.

Flexible raised 7 on the inwall of the shaft of a writing brush 2.Elastic bumps 7 can deform after being extruded, and can closely connect with pencil 11 Touch, increase fixed property between the shaft of a writing brush 2 and pencil 11.As shown in fig. 6, elastic bumps be wedge shape, by shaft of a writing brush inwall from top to bottom by Step becomes big, and its fastening effect is more preferable.

Embodiment 2

As shown in Fig. 2 point protector in the present embodiment, including the shaft of a writing brush 2 that upper and lower ends are open, pencil 11 is sleeved on the shaft of a writing brush In 2, the upper end of the shaft of a writing brush 2 is provided with a rubber case 4 that can load rubber 5, is threadedly coupled between rubber case 4 and the shaft of a writing brush 2 or plug-in type Connection.Be respectively installed with resilient rubbber cushion in the bottom and upper end of the shaft of a writing brush, bottom for lower rubber blanket 1, upper end For upper rubber blanket 3.In the present embodiment, the length of the shaft of a writing brush 2 is preferably suitable with the length of complete pencil, can unload when pencil is long Rubber case 4, the top of pencil can expose from one end of point protector, not affect the use of point protector.

Arranging point protector 4 conveniently can at any time embrocate modification wrong word.Simultaneously point protector 4 and rubber 5 increased end Weight, when falling from above, can make nib upward, strengthen the protection to nib.

In the present embodiment, other structures are repeated no more with embodiment 1.
