Specific embodiment：

Below in conjunction with the accompanying drawings to the design explanation for example.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, the unidirectional knife sharpener of the design includes handle 1, mill frame 8, and mill frame 8 is trapezoidal （Such as Fig. 2 shapes, right side visual effect fruit）, the front end of handle 1 is arranged at, frame is ground and connects by mill frame antetheca 7, mill frame rear wall 4 and its by the two The bottom plate 13 connect forms, mill frame be arranged to it is up-small and down-big it is trapezoidal can make its it is more stable be placed on desktop, conveniently grind behaviour Make；The one mill axis 9 of connection between frame front and rear wall is ground, grinds the emery wheel 5 that a trident of ining succession is worn on axis, and three of emery wheel 5 pitch The angle being disposed between one group of corase grinding mouth, one group of fine grinding mouth, one group of fine grinding mouth and three forks is all impartial hexagonal angle； The notch 2 of a rectangle is provided with from the top down in the end face center of mill frame rear wall 4, and the wall surface of mill frame rear wall is passed through in the rear end of mill axis 9 It reaches afterwards in notch and a flywheel gear 10 is fixedly connected on end, so-called flywheel gear refers to a kind of containing inner ring and outer ring Toothed geared system, the small fixture block for being commonly called as " very heavy " is provided between Internal and external cycle, when the gear of outer ring or the gear ring of inner ring When rotating in a direction it is very heavy cannot ratcheting drive inner ring rotate or outer ring rotating, but can be with Internal and external cycle when negative direction rotates Accompany and move, thereby movement characteristic can realize the function of some transmissions, and flywheel gear 10 is configured to turn in the direction of the clock It moves to rotate in an anti-clockwise direction state for non-idling, the i.e. clockwise rotation of outer ring teeth when flywheel gear for idle running When, the inner ring of flywheel gear cannot be driven rotation, and the enlarged view in Fig. 4 shows shape, i.e., this rotation direction causes outer ring Teeth cannot drive it is very heavy（Outer ring, internal ring gear are combined to the small fixture block of rotation i.e. in enlarged drawing）Inner ring can not be driven It rotates, that is to say cannot drive mill axis to rotate, conversely, when the anticlockwise rotation of the outer ring teeth of flywheel gear, flywheel The inner ring of gear can be driven rotation, i.e., this rotation direction, which enables the teeth of outer ring to drive, very heavy can also drive inner ring to turn Dynamic, that is to say can drive the synchronous rotation in the same direction of mill axis；A upright stretching is connected with the right side of flywheel gear 10 is ratcheting A toothed rack 3 on mill frame rear wall top surface, rack are arranged with a spiral helicine compression spring 11, and pressing rack causes tooth Teeth on item drive flywheel gear to move in the direction of the clock 120 degree of angles, this is the i.e. idle rotation of idle running as previously described, I.e. such rotation will not drive mill axis to rotate, and after unclamping rack, rack recovers former upwards under the action of spring power Position can drive flywheel gear to turn round counterclockwise so as to drive the inner ring of flywheel gear, mill axis, emery wheel are in the same direction to turn again again 120 degree of angles are moved, i.e., such rotation is not dallied, and is working condition, natural return can be very again by pressing the top of rack Adjusting upward one by one easily is carried out to the fork of the device ground on emery wheel so that corase grinding mouth, fine grinding mouth refine mouth court one by one On, facilitate grinding to cutter 12；As shown in figure 5, specifically used middle pull cutter is on ground 6 when carrying out grinding operation, It is seen that emery wheel can be subject to the power rotated in an anti-clockwise direction and generate the movement tendency in this direction（By the position of Fig. 5 From the point of view of state）, it is this to influence from the point of view of reflecting to the location status of Fig. 4, it can be seen that emery wheel drives mill axis to drive flywheel gear again Inner ring drives the outer ring of flywheel gear to move in the direction of the clock again, and the strength of this last movement can pass to rack and make it Compression spring downwards, certainly, the strength of this movement tendency is smaller, and the elastic force of spring in itself also can be unfavorable for grinding to this The movement tendency of operation generates interception, meanwhile, both make the rotation for certain angle occurred, the elastic restoring force of spring also can Timely by above-mentioned transmission by the ground on this fork to work on emery wheel be returned to again upward grind state （By the analysis description of this part it is not difficult to find that the as shown in Figure 5 state that grinds is suitable for left hand and holds the handle right hand taking out to the left Broaching tool has the mode for grind operation, this is also the operating habit of most people, if the pull knife to the right of negative direction Tool come carry out the pull of cutter grind it is then relatively difficult：Reversed emery wheel, which rotates trend, can not obtain the prevention of rack spring, Emery wheel can rotate in draw process, it is impossible to meet the needs for grinding operation）；It can be as after a ground pull is ground several times The upper rack that presses again adjusts out next ground, this so as to very easily complete entire sharpening process Pull grind the mode of cutter and disclosure satisfy that the operation needs of most people to the left.
