Knife-grinder

Abstract

A knife-grinder has a body and a grinding device. The body has a handle segment and a mounting segment. The handle segment is formed on a rear end of the body. The mounting segment is formed on a front end of the body, is formed on and protrudes from the handle segment and has a chamber, an opening, two pivot holes and a major grinding mouth. The grinding device is detachably mounted in the body and has two pivot rods, a first grinding element and a second grinding element. The pivot rods are respectively mounted in the pivot holes of the mounting segment. The grinding elements are respectively, rotatably and movably mounted around the pivot rods, and each grinding element has a spacing disk and two grinding slices. The grinding slices are respectively, rotatably and movably mounted around the pivot rods beside the spacing disks in an alternative arrangement.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a knife-grinder, and more particularly to a knife-grinder that can be used to grind knifes at multi-directions.[0003]2. Description of Related Art[0004]A conventional knife-grinder has multiple sharpening stones or grinding slices interoperable with each other to sharpen or grind the cutting-edges of the knifes. However, the sharpening stones or grinding slices are mounted securely in the conventional knife-grinder and cannot be moved relative to each other to adjust or change the angles between the sharpening stones or the grinding slices, and so the conventional knife-grinder can only sharpen or grind the cutting edges of the knifes at a specific angle. Then, the conventional knife-grinder cannot be used to sharpen or grind all kinds or sizes of knifes. In addition, the cutting edge of a knife has to be inserted between the sharpening stones or the grinding slices at the specific angle...

AI Technical Summary

Benefits of technology

The present invention is a knife-grinder that is designed to grind knifes from multiple directions. It has a body with a handle and a mounting segment, which is formed on the front of the body and protrudes from the handle. The grinding device is detachably mounted in the body and has two pivot rods, a first grinding element, and a second grinding element. The grinding elements are rotatably and movably mounted around the pivot rods and each has a spacing disk and two grinding slices. The grinding slices are alternatively arranged and extend into the major grinding mouth of the mounting segment. Overall, this invention allows for more versatility and flexibility in grounding knifes.

Problems solved by technology

However, the sharpening stones or grinding slices are mounted securely in the conventional knife-grinder and cannot be moved relative to each other to adjust or change the angles between the sharpening stones or the grinding slices, and so the conventional knife-grinder can only sharpen or grind the cutting edges of the knifes at a specific angle.

Then, the conventional knife-grinder cannot be used to sharpen or grind all kinds or sizes of knifes.

In addition, the cutting edge of a knife has to be inserted between the sharpening stones or the grinding slices at the specific angle for being sharpened or grinded and this is inconveniently in use.

However, the components of the conventional adjusting device are complicated and this will increase the cost of production and the time of assemble of the conventional adjusting device.
