Abstract

Disclosed is an electrical driven sharpener. It is characterized in that: the utility model comprises a shell, inside which an electric motor is fixed; the shaft of the electric motor is from the upper part to the lower part sequentially nested with a pressing spring, a chuck of a sleeve, a rub-stone for milling the knife and a bracket; a transverse pin arranged on the shaft of the electric motor is arranged inside the symmetrical slot mouth of the chuck of the sleeve; the pressing spring , which is nested on the upper end of the shaft of the electric motor, is contacted with the upper end face of the chuck of the sleeve; the rub-stone for milling the knife is fixed on the chuck of the sleeve; the bracket is arranged on the lower end of the shaft of the electric motor by means of a bearing; the bottom of the shell is provided with a base; a guiding rail of the base is provided with a moving frame for putting the knife that matches with the guide rail; a magnet for fixing a kitchen knife is arranged inside the moving frame for putting the knife; the place of the base for putting the knife is provided with a limit ring of a fixed-axis rotation. As the rub-stone for milling the knife has a good flexility, and thus the utility model is firm and durable and only produces little heat when grinded with the blade of the kitchen knife without adding water to cool the blade and does not damage the cutting edge. The utility model has the advantages that grinding operating time is short and the speed is fast, the grinding angles of the blade of the kitchen knife are identical, the blade is sharp, saves labor and time and the grinded kitchen knife has a long service life.

Description

Electric knife sharpener

Technical field

The utility model belongs to knife sharpener, more particularly, is a kind of electric knife sharpener that is mainly used in the blade that sharpens a kitchen knife.

Background technology

The existing use hand grinder that sharpens a kitchen knife usually sharpens a kitchen knife and puts the first edge on a knife or a pair of scissors, and finish grindes blade with grinding stone again, till blade is sharp.Because the grinding angle of kitchen knife blade is difficult to guarantee the grinding angle of blade by people's hand control, and is often improper because of grinding angle, and need for a long time mill repeatedly, and promptly take cutter, expense emery wheel and grinding stone, take a lot of work again, time-consuming, the grinding operating speed is slow, and kitchen knife is short service life.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of grinding angle of kitchen knife blade to be determined that by mobile knife-carrier the grinding activity duration is short, speed is fast, and blade is sharp, the saving of labor, saves time, and is easy to use, easy and simple to handle, the electric knife sharpener of kitchen knife long service life.

Solving the technical scheme that its technical problem takes is: a kind of electric knife sharpener, it is characterized in that: it comprises housing 1, in housing 1, be fixed with motor 2, motor shaft 15 is nested with compression spring 3 from top to bottom successively, muff chuck 4, sharpening whetslate 6 and rest 12, the lateral pin 5 that is provided with on the motor shaft 15 places in the symmetrical notch of muff chuck 4, the compression spring 3 that is nested with in motor shaft 15 upper ends contacts with muff chuck 4 upper surfaces, sharpening whetslate 6 is fixed on the muff chuck 4, rest 12 is contained in motor shaft 15 lower ends by bearing 11, be provided with base 10 in housing 1 bottom, on the guide rail 16 of base 10, be equipped with the mobile knife-carrier 9 that matches with guide rail 16.In described mobile knife-carrier 9, be provided with the fixedly magnet 7 of kitchen knife.Put knife-edge part at described base 10 and be provided with the spacing ring 14 that dead axle rotates.

Electric knife sharpener of the present utility model, owing to adopt sharpening whetslate, sharpening whetslate has good pliability, and is sturdy and durable, only produces slight heat during with the grinding of kitchen knife blade, need not add the water cooling blade, to the cutting edge not damaged; Because driven by motor sharpening whetslate rotation, sharpening whetslate is exerted pressure by compression spring, sharpening whetslate contacts with the kitchen knife blade of placing on mobile knife-carrier, what the grinding angle of kitchen knife blade depended on mobile knife-carrier puts the nose angle degree, have the grinding activity duration short, speed is fast, the grinding angle of kitchen knife blade is consistent, blade is sharp, the saving of labor, save time, easy to use, easy and simple to handle, advantages such as kitchen knife long service life.Also can put the mobile knife-carrier of nose angle degree, realize the grinding operation of multiple different size kitchen knife blade by difference is set.
