Abstract
The utility model discloses a pencil lengthener comprising a body which is a hollow rod-shaped casing. The hollow rod-shaped casing is divided into three parts including a handheld part, a cylindrical pencil clamping part and a hexahedron pencil clamping part. The cylindrical pencil clamping part is arranged at one end of the handheld part, the diameter of an inner hole of the cylindrical pencil clamping part is larger than that of an inner hole of the handheld part, the hexahedron pencil clamping part with hexagonal section is arranged at the other end of the handheld part, limit pits or/and limit projections are arranged on connecting transition surfaces of the hexahedron pencil clamping part and the handheld part as well as the cylindrical pencil clamping part and the handheld part, and the handheld part beside the limit pits or/and limit projections is provided with clamp grooves. The pencil lengthener is conducive to use of pencils when sharped to be quite short, and brings convenience for the pencils to be sharpened in a pencil sharpener. Besides, the pencil lengthener is simple in structure, high in cost performance and cost saving and more importantly, is environment friendly and forest resource saving.
Description
Technical field
The utility model relates to a kind of stationery, is specifically related to a kind of pencil lengthening device.
Background technology
The pencil of knife cutting type is used and is often just dropped (being commonly called as pencil stub) very short time, cause the waste of resource, also there are a lot of children adhering to so short pencil, what be unfavorable for like this that child forms writes gimmick custom, even if so also can only use 45-50 millimeter, just can not adhere to having used again, finally still must be dropped, although there has been the lengthener for lengthening pencil under prior art, but its complex structure, cost is high, and inconvenience is used in conjunction with the hand pencil sharpener on market.
Utility model content
The utility model is mainly for the problem of the waste of pencil resource and pencil stub inconvenience cutting, special provides a kind of pencil lengthening device.
To achieve these goals, the utility model solves the technical scheme that its technical problem adopts: a kind of pencil lengthening device, comprise body, body is the shaft-like sheath body of a hollow, the shaft-like sheath body of described hollow is divided into three parts, it is respectively Handheld Division, cylinder pencil holding portion, hexahedron pencil holding portion, cylinder pencil holding portion is arranged on one end of Handheld Division, and its diameter of bore is greater than the diameter of bore of Handheld Division, the aperture degree of depth is 5-10mm, hexahedron pencil holding portion is arranged on the other end of Handheld Division, its cross section is hexagon ring-type, and longitudinal length is 5-10mm, be positioned at hexahedron pencil holding portion and cylinder pencil holding portion and be provided with spacing pit or/and spacing preiection with being connected on transition face of Handheld Division, at described spacing pit or/and offer draw-in groove on the Handheld Division of spacing preiection one side.
Furtherly, the degree of depth of described draw-in groove is half of Handheld Division diameter of bore.
Furtherly, described cylinder pencil holding portion and hexahedron pencil holding portion are all smooth excessive connections with the surface of junction, Handheld Division.
The beneficial effects of the utility model: this pencil lengthening device that the utility model provides contributes to pencil to be cut to very in short-term can also well to be used, and Convenient pencil cuts in cutter, and structure is extremely simple, cost performance is high, save money, the more important thing is environmental protection, save the forest reserves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
The specific embodiment
Below in conjunction with the detailed explanation of the accompanying drawing specific embodiment of the present utility model, a kind of pencil lengthening device as depicted in figs. 1 and 2, comprise body 1, body 1 is the shaft-like sheath body of a hollow, the shaft-like sheath body of described hollow is divided into three parts, it is respectively Handheld Division 2, cylinder pencil holding portion 3 (be used for socket and clamping cross section are the end of circular pencil), hexahedron pencil holding portion 4 (be used for socket and clamping cross section are hexagonal pencil end), cylinder pencil holding portion 3 is arranged on one end of Handheld Division 2, and its diameter of bore is greater than the diameter of bore of Handheld Division 2, the aperture degree of depth is that 5-10mm is (for the intensity that guarantees that pencil is inserted in, writing Shi Buhui comes off), hexahedron pencil holding portion 4 is arranged on the other end of Handheld Division 2, its cross section is hexagon ring-type, and longitudinal length is that 5-10mm (is the intensity in order to guarantee that pencil is inserted in equally, writing Shi Buhui comes off), be positioned at hexahedron pencil holding portion 4 and cylinder pencil holding portion 3 and be provided with spacing pit or/and spacing preiection (is mainly used to limit the degree of depth that pencil is inserted in being connected on transition face of Handheld Division 2, convenient taking-up is not stuck), at described spacing pit, or/and offer draw-in groove 5 on the Handheld Division 2 of spacing preiection one side, (draw-in groove 5 is to be convenient to allow the fixing pencil lengthening device of catching of pencil sharpener, thereby better sharpening pencil, play in addition the effect of pencil lengthening device axial location, pencil lengthening device can not be cut or damage pencil sharpener).
A preferred embodiment of the present utility model, the degree of depth of described draw-in groove 5 is half of Handheld Division 2 diameter of bores; Described cylinder pencil holding portion 3 and hexahedron pencil holding portion 4 are all smooth excessive connections with the surface of 2 junctions, Handheld Division, and the super good sense of holding is provided.
