Abstract

The present invnetion includes a sharpener for sharpening cutting tool (for example knife and scissors) by using a grinding disc or steel disc, in which it possesses a U-shaped self-body like an opened handle, and its bottom side is equipped with a support or a supporting surface. Said U-shaped self-body possesses a receiving piece which is projected toward the frout of said sharpener device for fixing the grinding disc or steel disc, under the receiving piece a ceramic rod is placed, and said ceramic rod can be longitudinally forward moved to repair the irregular edge of cutting tool to be sharpened.

Description

Portable sharpener for cutting tool

The present invention system is about utilizing an abrasive disc or steel disc to come the device and method of sharpening cutting tool (for example knife, scissors etc.).

The device of cutting tool sharpening is generally comprised installing one grinding or steel sharpening member on flat handle.In order to grind, blade must place on the Grinding structural unit with the blade sharpening.The shortcoming of this prior art is can not be supported on the stationary plane to hold unstable operator scheme running.Therefore, do not have the user of experience instrument to be turned the edge of because grasping tool and DeviceMode are incorrect, rather than sharpening.

The object of the present invention is to provide a kind of device of above-mentioned pattern, it can effectively use, even inexperienced user also can use it to come the sharpening cutting tool.

For this reason, now provide a kind of device with the cutting tool sharpening, it comprises that one grinds or steel sharpening element, has an elongated sharpening edge substantially, it is characterized in that a body that is generally U-shaped is designed to an open handle, and establishes one in its bottom side and support or supporting surface.The U-shaped body also is provided with a member that protrudes out towards the extension of sharpening apparatus front end, is used for fixing and grinds or steel sharpening element.Below protruding out member a ceramic bar is arranged, it optionally moves towards the sharpening apparatus at length direction.

The big advantage that sharpener device of the present invention is provided be for can stably support or support to lean against (for example desk) on the stationary plane, and allows the user utilize U-shaped body handle steadily to hold.Then make the cutting tool cutting edge across fixing grinding or the pulling of steel sharpening element and with the cutting tool sharpening.In addition, protruding out below the member and can be the irregular equating in the cutting edge of instrument that can sharpening at the ceramic bar that vertically moves between a retracted position and the extended position at cutting edge during across ceramic bar.According to a preferred embodiment, the fixing grinding or the protruding out sheet and can be designed to of steel sharpening element toward 10 ° that tilt.Allow processing of the present invention and use be more prone to.

Ceramic bar can be fixed on the plastic actuator element, moves in the recessed or slotted eye of of making that it can be in U-shaped body bottom of the latter's installing, so that ceramic bar is displaced between retracted position and the extended position.

At last, the fixing grinding or the protruding out member and can establish a negative area of steel sharpening element in the bottom, and the lid that utilizes an energy to slide on the U-shaped body covers.The lower surface copline of the lower surface of lid and U-shaped body makes lid can not only protect ceramic bar, also can improve U-shaped body stability of strutting system in use.

Under following accompanying drawing cooperates, sharpener device of the present invention will utilize a preferred embodiment form to introduce in detail.

Fig. 1 is the side view of sharpener device of the present invention;

Fig. 2 is the vertical view of sharpener device of the present invention;

Fig. 3 is the front view of sharpener device of the present invention;

Fig. 4 is and the similar vertical view of Fig. 2 that wherein over cap is in the location;

Fig. 5 is the profile of being got along 5-5 line among Fig. 1;

Fig. 6 is the profile of being got along 6-6 line among Fig. 4.

As shown in the figure, sharpener device of the present invention comprises a U-shaped body 1, and its shape will be installed firm the gripping just like the leader for one hand, have a hole 2 to pass in the handle.Body 1 is established a flat support or seating surface 3 in the bottom side, in order to the firm twelve Earthly Branches of body by on the surface of stability, for example desk or sales counter end face, floor, wall or the like.

The front end of U-shaped body 1 be provided with one protrude out forward hold sheet 4, for a plastic fixer 5 stretch into and with one grind or steel sharpening element 6 fixing.Protrude out and hold sheet 4 and also up extend a low-angle, upper surface and seating surface 3 that sharpening member 6 is exposed form about 10 ° of angles.In this preferred embodiment, sharpening element 6 is shaped as a bar, but also can be other shapes, as long as its function is identical.

Protrude out the bottom side that holds sheet 4 and be provided with a concave region 7, so that fixedly circular cross-section ceramic bar 8 and ceramic bar 8 can lengthways move.Ceramic bar be used for making to grind or the irregular or uneven place of the cutting tool (making the cutting tool cutting edge) of sharpening across ceramic bar smooth-going.For this purpose, ceramic bar 8 is connected to a plastic actuator 9, and its position can be slided it in U-shaped body 1 bottom.For it can be vertically moved, actuator 9 is provided with a block 10 that extends in the intrinsic cannelure 11 of U-shaped, and block 10 can be vertically moved in groove 11 with user's finger.

One big advantage of sharpener device of the present invention is when leaning against a stationary plane (for example desk or sales counter end face, floor or wall) and U-shaped body 1 is supported on the stationary plane on the other hand firmly gripping and to force.Afterwards, with another hand will sharpening the cutting tool edge across grinding or 6 pullings of steel sharpening element.

In order to protect ceramic bar 8, a lid 12 can be pressed in and protrude out sheet 4 downsides top.The lower surface of lid 12 is preferably the plane, when leaning against when protruding out on the sheet 4, with face 3 coplines, more firmly leans against on the stationary plane when sharpener device is used.

Claims

1. the type of holding device with cutting tool cutting edge sharpening comprises:

One body, its first side is established leader's supplying apparatus operator's a firm grasping of hand, body has a smooth seating surface in second side relative with first side, when the operator with the proficiency grasps handle, the user can this hand application of force be pressed against seating surface on one fixed support surfaces, for example desk or sales counter end face, floor or wall; And

Wherein want the cutting tool cutting edge of sharpening to be held and to be spurred along the sharpening element by second of operator by the fixing sharpening element of body for one, seating surface then is pressed against on the fixed support surfaces.
