Electrical knife sharpening device

Abstract

A knife sharpening device includes a base with a motor and a gear reduction assembly connected thereto. A main shaft is connected to the gear reduction assembly and two grinding disks are mounted on the main shaft. A separation tube is mounted on the main shaft and located between the two grinding disks. Each grinding disk has a spring urging thereto so as to prevent the grinding disks from shaking. A cover is mounted to the base and has straight slots each of which is in communication between two openings. Each slot includes two narrow ends which communicate with the two openings so that the blades of knives are inserted perpendicularly in the slots and the cutting edge is slightly clamped by the narrow ends.

What is claimed is:  
     
         1 . An electrical knife sharpening device comprising: 
 a base;    a motor connected to the base and a gear reduction assembly connected to an output shaft of the motor, a main shaft connected to the gear reduction assembly, two grinding disks mounted to the main shaft and a separation tube mounted to the main shaft and located between the two grinding disks, two springs mounted on the main shaft and pushing the two grinding disks toward the separation tube, and    a cover mounted to the base and having straight slots defined therethrough to access the grinding disks, a grinding surface of each of the grinding disks being located at an angle relative to the slot corresponding thereto.    
     
     
         2 . The knife sharpening device as claimed in  claim 1  wherein each straight slot is in communication between two openings.  
     
     
         3 . The knife sharpening device as claimed in  claim 2  wherein each straight slot includes two narrow ends which communicate with the two openings respectively.
