Abstract
The invention discloses a pencil sleeve of a straight rod structure. A groove is formed in one end of the pencil sleeve, and the inner diameter of the groove is slightly smaller than the outer diameter of a pencil. By the adoption of the straight rod structure with the groove in one end, the inner diameter of the groove is smaller than the outer diameter of the pencil, so one end of the pencil can be clamped in the groove, a user can continue writing by holding the straight rod, so a remaining pencil head can be well used, and resources are saved.
Description
Technical field
The present invention relates to field of stationery, especially a kind of point protector.
Background technology
Pencil uses very general a kind of stationery, is generally to adopt the coated cylindric pencil-lead of pine to form.During use, pocket knife is pruned pine layer, and exposing pencil-lead can write.In actual use owing to being directly hold pencil to write, will hold when being only left several centimeters and continue to employ, thus cause the pencil length taking about 1/4th, will be abandoned, cause great waste.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of point protector, structure is ingenious, economizes on resources.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of point protector, be straight-bar structure, its one end is provided with groove, and the internal diameter of this groove is slightly less than pencil external diameter.
Further, described groove is circular groove, and its inwall is provided with screw thread.
Further, described depth of groove is 1 ~ 2cm.
Compared with prior art, the present invention has the following advantages: adopt one end to establish reeded straight-bar structure, this groove internal diameter is less than pencil external diameter, such pencil one end just can be fastened in this groove, hold straight-bar to continue to write, the pencil stub be left can be used well, economize on resources.
Accompanying drawing explanation
Fig. 1 is the structural representation of point protector of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of point protector as shown in Figure 1, be straight-bar structure 1, its one end is provided with groove 2, and the internal diameter of this groove 2 is slightly less than pencil external diameter.When pencil uses to too short cannot holding, will remain pencil one end extexine truncated section, firmly insert in this groove 2, both immovable fitting, hold straight-bar structure 1, can continue to use residue pencil send a letter here to write.
Groove 2 is circular groove, and its inwall is provided with screw thread; No matter pencil extexine is circular or square, and top layer of pruning all can be threaded in circular groove along this, simple to operate, in conjunction with firm.
Groove 2 degree of depth is 1 ~ 2cm, and this degree of depth can ensure that point protector firmly fixes pencil, substantially increases the actual use amount of pencil, has relatively saved resource.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
