Abstract
The utility model discloses a constitute pencil sharpener by blade, shell, the inside coniform cavity that is of pencil sharpener shell is equipped with the edge of a knife on the awl wall, is equipped with the sword platform with edge of a knife department of meeting, and the blade is fixed on it, is equipped with the fixed orifices on the blade, and the shell is equipped with fixture block and nail post in sword platform department, prevents it by fixture block fixed blade and upwarps, still is equipped with the draw-in groove on the shell to further block the head of blade. Because the utility model discloses only through add some plastics fasteners on the shell, make the production technology of pencil sharpener simplify greatly, reduced the material and used, improved production efficiency, reduced manufacturing cost.
Description
Technical field
The utility model relates to a kind of manufacturing field of stationery, relates in particular to a kind of manufacturing of pencil sharpener.
Background technology
Pencil sharpener is a kind of instrument that the student uses always.Pencil sharpener in the market generally all is to be made of blade and pencil sharpener shell, and a bellmouth that is used to insert pencil is generally arranged on the pencil sharpener shell, establishes an edge of a knife on hole wall, along edge of a knife face one blade platform is arranged, fixed blade on it.Because the fixing of blade generally all is to fix by screw, therefore wastes time and energy in the pencil sharpener production process, and takes material, production cost is higher.
Summary of the invention
The purpose of this utility model just provides a kind of pencil sharpener without the screw fixed blade.
The utility model is realized by following manner: constitute pencil sharpener by blade, shell, enclosure is coniform hollow, the awl wall is provided with the edge of a knife, be provided with the cutter platform with edge of a knife joint, blade is fixed on it, and blade is provided with fixing hole, shell be provided with at cutter platform place fixture block and the nail post, prevent that by the fixture block fixed blade it from upwarping, also be provided with draw-in groove on the shell, further to block the head of blade.
Only by on shell, having set up some plastics fasteners the production technology of pencil sharpener is simplified owing to this is practical greatly, reduced the material use, improved production efficiency, reduced production cost.
Description of drawings
Fig. 1 is a pencil sharpener surface structure schematic diagram;
Fig. 2 is the broken section structural representation of pencil sharpener shell;
Fig. 3 is the blade structure schematic diagram.
The specific embodiment
Shape need according to the pencil sharpener shell makes injection molding mould earlier, in mould, reserve the hole of corresponding fixture block 2, cutter groove 4, discharging opening, utilize the locating hole 5 on the blade that blade 1 is fixed in the mould then, in mould, inject thermoplastic afterwards, make liquid plastics inject the interior various piece of mould, after the cooling, closely cooperate by plastics and blade, and form the fixture block 2 of fixed blade at the blade middle part, form the cutter groove 4 of parcel point of a knife at the point of a knife place, finished the technical pattern feature that the utility model had thus.
