Abstract
The utility model provides a magnetic knife sharpener, which comprises a knife placing rack, wherein a magnetic body is arranged on the knife placing rack. Therefore, cutting edges of a cutter can be maintained sharp for a long time through magnetic force, and the service life of the cutter is consequently prolonged, which is especially advantageous for the special cutters that are inconvenient or unable at all to grind.
Description
Technical field
The utility model relates to a kind of magnetic force that utilizes makes cutter keep sharp to prolong the magnetic force sharper of cutter life.
Background technology
At present, the cutter that used various of people have a blade in use for some time, blade just can be no longer sharp because of wearing and tearing, at this moment, people can adopt the method for grinding usually, make cutter become sharp again after thin blunt blade polishing.But the method with grinding can tool setting have loss, shorten the service life of cutter, and some special cutter is not convenient to maybe can't carry out grinding, as the cutter that uses on daily used shaver blade and some precision instruments, their service life is just shorter.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of magnetic force sharper, and this magnetic force sharper can reduce wear the blade of cutter by magnetic force, makes blade keep sharp for a long time, thereby significantly prolongs the service life of cutter.
The technical scheme that its technical problem that solves the utility model adopts is that permanent magnet or electromagnet are set on knife-carrier.The cutter rust be since cutter in use, the external force that acts on the blade generally can not be kept in balance, and blade is thinner usually, the intermolecular gravitation that is positioned at the blade place is relatively weak, the molecular arrangement at blade place just can become unordered in a jumble because of the effect of external force like this, repeatedly use the back just to cause the concentrated wear of blade easily, no longer sharp.But when after cutter uses, being put on the knife-carrier of the present utility model, because cutter is in the magnetic field of magnet generation, molecule in the cutter can move under the effect of magnetic force, make the molecular order that is positioned at the blade place recover closely neat again, thereby make blade be not easy to occur concentrated wear, can keep sharp for a long time, reach the purpose that prolongs cutter life.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the utility model.
Fig. 2 is the structural representation of second embodiment of the utility model.
The specific embodiment
By shown in Figure 1, the magnetic force sharper is made of knife-carrier 2 and the magnet 1 that is positioned on the knife-carrier 2, knife-carrier 2 is shaped as cuboid among Fig. 1, but the shape of knife-carrier 2 can be according to the shape conversion of cutter when practice the utility model, but the position of knife-carrier 2 upper magnets 1 preferably is positioned at the top of blade.
In the embodiment shown in Figure 2, the both sides of knife-carrier 2 are fixed with a magnet 1 respectively, and magnet 1 can be selected permanent magnet for use, the also optional electromagnet of using.
To pick must cutter be object, uses second embodiment to oppose than the result such as the following table of test:
| Time | Fate | Access times | A blade (plain cutter holder) | B blade (magnetic force sharper) |
| 2004.12.10～12.19 | 10 | 5 | Sharp | Sharp |
| 2004.12.20～12.29 | 10 | 5 | Sharp | Sharp |
| 2004.12.30～1.08 | 10 | 5 | Sharp | Sharp |
| 2005.1.09～1.18 | 10 | 5 | Sharper | Sharp |
| 2005.1.19～1.28 | 10 | 5 | Sharper | Sharp |
| 2005.1.29～2.07 | 10 | 5 | Not sharp | Sharp |
| 2005.2.08～2.17 | 10 | 5 | Not sharp | Sharp |
| 2005.2.18～2.27 | 10 | 5 | Slight pain is arranged | Sharp |
| 2005.2.28～3.09 | 10 | 5 | Obvious pain is arranged | Sharp |
By reaching trimestral comparative test result as can be known, the magnetic force sharper that uses the utility model to provide can prolong the service life of cutter more than one times at least, and this will play great saving effect to resource.
