Abstract
The invention discloses a handheld portable knife grinder. The handheld portable knife grinder is characterized by comprising two bases, two grinding stones and hand-protecting blocking sheets. Each base comprises a bottom plate and a connecting plate arranged on the two short edges of the bottom plate, and the connecting plate is of a T shape. The two bases are connected together in a hinged mode through connection points arranged on the connecting plates. The other side of each base is further provided with an anti-skid stop dog. Each grinding stone is divided into three segments, a grinding stone connecting shaft penetrates through the three segments of each grinding stone to gather the corresponding three segments together, and the three segments of each grinding stone are movably connected to the corresponding connecting plate. The hand-protecting blocking sheets are arranged on the two sides of the bottom plates, and the outer sides of the grinding stones are half wrapped with the hand-protecting blocking sheets. The handheld portable knife grinder has the advantages that various knives with different knife edge thicknesses can be effectively sharpened; by the adoption of the mode that the grinding stones are in rolling connection, the surfaces of the grinding stones are evenly worn, and the utilization rate of the grinding stones is improved; the knives can be sharpened through the knife grinder in a handheld mode, and the knife grinder is light in weight, and is suitable for being carried with when a user goes out.
Description
Technical field
The present invention relates to the kitchen utensils in a kind of daily life, specifically a kind of portable whetstone.
Background technology
All kinds of cutters that use in daily life in use for some time, inevitably can become slightly blunt, now need to use whetstone the cutter of thick is carried out to reconditioning, and therefore whetstone is kitchen utensils indispensable in people's daily life.And the whetstone that people use in kitchen is now generally square single structure, when using, this whetstone is difficult for fixing, and easily skid and easily hurt hand; Also having in addition some is circular knife-grinding appliances, but after this whetstone utensil use a period of time, the circular structure of grinding stone is destroyed, and grinding stone can not be changed, and therefore the reconditioning ability of cutter is declined.Two kinds of above-mentioned knife-grinding appliances also all have not portative feature, and under Wu's safeguard measure, square whetstone is also easily because collision is ruptured.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the invention provides one portable, the portable sharpening stone of sharpening excellent in efficiency, in order to achieve the above object, the present invention specifically adopts following technical scheme:
One is held portable sharpening stone, it is characterized in that, comprising:
Base, it is the bracing frame of holding portable sharpening stone described in whole, comprising base plate and connecting plate, described base plate is rectangular sheet, arrange altogether two, on two minor faces of described base plate, be provided with described connecting plate, the in T shape and described base plate of described connecting plate is fixedly connected with, and stretch out a part along the minor face of described base plate, the part that described two base plates stretch out by described T font connecting plate is hinged;
Grinding stone, be arranged to cylindricality, its inside is provided with the grinding stone connecting axle through described grinding stone, described grinding stone connecting axle is movably connected between two described connecting plates that arrange on described base plate, concrete tie point is the part of described connecting plate to downward-extension, the described connecting portion that is aimed at described base plate and described connecting plate downwards;
Handguard catch, be arranged to the rectangular sheet consistent with described floor length, be connected to the outer long side of described two base plates and to downward-extension, its height is higher than the height that is arranged on the described grinding stone on described base plate, and the outer long side of described base plate is aimed at the hinged place of described two base plates.
Preferred scheme is: described grinding stone is cylindrical, when described two bases pin joint are that round dot is while relatively rotating to the inside, drive two described grinding stones of side disposed thereon mutually to draw close, its contact-making surface has formed the ascending angle of angle by the face of cylinder, is more suitable for so all kinds of cutters with different thickness of knife edge and carries out reconditioning; Described grinding stone connecting axle is applied on its axis, described grinding stone is flexibly connected with described connecting plate, be convenient to described grinding stone to be rotated the face of selecting wearing and tearing less, often this such use can keep its cylindrical structural to keep the efficiency of its sharpening preferably.
Preferred scheme is: described grinding stone is at least divided into three sections, is equidistantly arranged on described grinding stone connecting axle.Due in the process of whetting a knife, the grinding efficiency of the initial contact-making surface of grinding stone and blade is the highest, and described grinding stone is divided into multistage, just in time increase the initial contact-making surface of described grinding stone and blade, and increase the angle adjustable of whetstone blade, make reconditioning have more flexibility, increased the efficiency of reconditioning; Another advantage that described grinding stone is divided into multistage is the weight that has reduced to hold described in whole portable sharpening stone, makes it to carry more convenient.
Preferred scheme is: described handguard catch is arranged to arcwall face, and its camber line bends towards described base plate inner side, has so not only increased palm and has held the degree of stability that described base is, and increased the comfort of holding.
Preferred scheme is: described handguard catch outer surface is provided with intensive reticulate pattern.In the time holding portable sharpening stone cutter carried out to reconditioning described in using, can produce back and forth reciprocal thrust, make palm easily depart from described whetstone, be therefore extremely necessary intensive reticulate pattern to be set to increase frictional force at described handguard catch outer surface.
Preferred scheme is: also comprise Anti skid stop dog, be arranged on the another side of described connecting plate with respect to described base plate, and forming a curved surface to described base plate middle bent, it act as and palm is stopped when will depart from described base by high thrust when palm, prevents its landing.
Preferred scheme is also to comprise grinding cleaning rubber, is arranged on the both sides of described grinding stone, with described grinding stone radial parallel, and is fixed on described base plate, is attached to the chip on blade during for wiping reconditioning.
Using method of the present invention is: with palm across described two base plates and hold, be positioned at the described handguard catch of thumb one side by thumb press, now described two bases are taking pin joint as round dot rotation relatively to the inside, and drive two described grinding stones of side disposed thereon mutually to draw close, by blade be placed in grinding stone the face of cylinder form angle between push-and-pull back and forth, can fast blade be polished sharp.Of the present inventionly hold portable sharpening stone and also can be pressed on the ground and to use.
The advantage of holding portable sharpening stone of the present invention is, the angle of utilizing the face of cylinder that cylindrical grinding stone is in contact with one another to form is again little carries out reconditioning to large angle, make the polishing of all kinds of cutters with different thickness of knife edge more effective, grinding stone is divided into multistage has more increased the efficiency of reconditioning; Of the present inventionly hold portable sharpening stone and adopt grinding stone rolling connected mode, make grinding face even wearing, the utilization rate of grinding stone own is improved; Of the present inventionly hold the mode that portable sharpening Shi Keyong holds and carry out stage property reconditioning, hold good stability and be difficult for skidding; The present invention be advantageous in that lightweightly, be suitable for going out to carry.
