Description

Handheld convenient oyster opening knife

Technical Field

The utility model relates to the technical field of oyster opening tools, in particular to an oyster opening knife convenient to hold.

Background

The oyster is a food with very rich nutrition, and especially contains very rich zinc. Therefore, eating the oyster becomes one of the favorite foods of people. However, the oyster meat is dug out from the thick shell before eating the oyster. Because the shells of the oyster are hard, the oyster is difficult to dig.

At present, two types of existing oyster prying knives are common, one type of the existing oyster prying knives is a household common oyster prying knife, the knife is made of stainless steel, the knife handle is made of plastic, wood or stainless steel, the purpose of prying open the oyster gradually is achieved by repeatedly rotating the blade (2) at the edge of the oyster after the blade (2) is inserted into the oyster, and the defects are that the labor is wasted, and hands are easily cut due to careless operation while rotating the blade (2); the second type is a commercial oyster knife (oyster opener), which is provided with a base, the base is provided with a groove, a fixed rod is arranged on the base, and a stainless steel rod with a sharp plug is arranged on the base to achieve the purpose of inserting the oyster to break the oyster, so that the commercial oyster knife has the defects of higher price, limited use occasions and great limitation in popularization.

Disclosure of Invention

The utility model aims to overcome at least one defect of the prior art and provide the oyster opening knife which is convenient to hold, so that the aims of uniform stress, convenient use and small structure are fulfilled.

The utility model discloses a handhold convenient oyster opening knife which comprises a handle and a blade, wherein the connecting end of the handle and the blade is a front end, the other end of the handle is a rear end, and the handle comprises a first handhold part, a second handhold part and a third handhold part; the first handheld part is arranged on the side edge of the front end of the handle and is recessed inwards; for the thumb to hold; the second handheld part is arranged opposite to the first handheld part and is recessed inwards; for the holding of the index finger. The third handheld part is arranged at the lower side of the second handheld part, inclines from the rear end of the handle to the front end and is used for holding middle fingers, ring fingers and little fingers.

The prior art is mainly focused on the improvement of the blade structure, and the comfort level and the stress uniformity of the hand are not considered. Because of the great effort required in the oyster opening process, it is very necessary to improve the comfort level of the hand holding so as to achieve no hurt to the hand and to improve the oyster opening efficiency. The present application contemplates different finger grip locations wherein the first grip is for the thumb grip; the second handheld part is used for holding the index finger, the third handheld part is used for holding other fingers, the width of each holding part is matched with the width of different fingers, and the stress is more uniform.

Further, a boss is arranged between the second handheld part and the third handheld part, and the top of the boss is an elliptic plane; the height of the boss is equal to the height of the rear end of the handle.

The design of the boss separates the second handheld part from the third handheld part, increases the resistance of finger sliding, and simultaneously achieves the purpose of fixing the index finger and other fingers. The height of the boss is equal to the height of the rear end of the handle, so that the oyster opening knife can be stably placed on a table top or the ground and cannot roll at will. And the design of the elliptic plane can increase the contact area with the tabletop, so that the placement is more stable.

Preferably, the two sides of the boss are provided with arc-shaped concave parts for fitting fingers.

The utility model adopts the mode that the tail part is gradually thinned in the middle part, so that a space is reserved for holding the hand, and meanwhile, the height of the tail part can be matched with the height of the boss, thereby being convenient for placing an oyster opening knife.

Further, the first hand-held part is an arc-shaped concave, and the arc-shaped concave is formed by inclining from the rear end to the front end of the handle. Because the thumb is stressed and the thenar of the thumb needs to be attached and stressed, the utility model designs that the first hand-holding part is formed by inclining from the rear end to the front end of the handle, has larger concave area and is suitable for placing the whole thumb.

Further, the blade is embedded from the front end to the rear end of the handle; the first handheld portion is provided with a first through hole, the second handheld portion is provided with a second through hole, the blade is provided with a third through hole, and the first through hole, the second through hole and the third through hole are fixedly connected through threaded fasteners.

Further, the blade comprises a blade body part and a blade tip part, wherein the blade body part and the blade tip part are integrally formed; the knife tip part is tilted upwards.

Preferably, the nose part is a circular arc-shaped rocker.

Preferably, the angle of tilting of the knife tip part relative to the plane of the knife body part is 7-9 degrees. In practical application, the angle of tilting the cutter point part relative to the plane of the cutter body part is 7-9 degrees, and more preferably 8 degrees, in consideration of uniformity of stress and better realization of stress, and is convenient to cut into the oyster shell.

Compared with the prior art, the utility model has the beneficial effects that:

the present utility model contemplates different finger gripping positions wherein the first hand grip is for the thumb grip; the second handheld part is used for holding the index finger, the third handheld part is used for holding other fingers, the width of each holding part is matched with the width of different fingers, and the stress is more uniform. Meanwhile, the whole table can be stably placed on a table top, and is more convenient to hold and store. The influence of the tilting angles of the different knife tip parts on oyster opening stress is examined, and the angle is preferably 7-9 degrees, so that the oyster opening is more time-saving and labor-saving.
