Abstract
The utility model relates to a cutter provided with a streamlined handle, which comprises a cutter body, a grab handle and a finger press section. Taking the rear end of the finger press section as a base point, the finger press section is formed by being twisted to the tail end thereof; a tool shank that is formed through twisting is matched with the grab handle; a thumb press surface which is a concave surface is formed at the top of the finger press section; the thumb press surface is matched with a thumb surface; an index finger holding surface which takes the shape of V is formed at the lower part of the finger press section; an upper component and a lower component are arranged on the grab handle, and the upper component is a palm grab handle, the lower end of which is matched with the upper part of the tool shank that is formed through twisting; the lower component is a finger grab handle, of which the upper end is matched with the lower part of the tool shank that is formed through twisting; the upper end of the palm grab handle and the lower end of the finger grab handle form a symmetrical arc; the line of a knife back and the upper arc of the palm grab handle form a streamline; a cutting edge extending from a knife point to the lower right end of a cutting board takes the shape of an arc; and the tail end of the grab handle is processed into an internally tangent inclined plane.
Description
Technical field
The utility model relates to cutter, and what be specifically related to is the cutter of band streamline handle.
Background technology
In life, cutter is the instrument that people use always, and thumb is pressed on the knife back that does not have the finger pressure face, the long-time use, and cocoon will appear in thumb, and these cocoons are because the knife back is uncomfortable, due to the wearing and tearing; In addition, the cutter that prior art is produced, the phenomenon that ruptures or come off often appears in the junction of handle of a knife and cutter hub, and no lever cutter can't use; Because existing cutter lever is dolioform, the thumb pressure point is little, and stressed pressure point of knife plate and blade point of contact make cutter depart from objectives often not at grade easily, and therefore accidents happened easily.
The utility model content
The purpose of this utility model is the cutter that the band streamline handle will be provided, and solves the defective that existing cutter uses; Lever is provided with the cutter of finger pressure face, is characterized in: the finger pressure face is vertical with the knife back, enlarges the lifting surface area of finger pressure, can make stressed pressure point of knife plate and blade point of contact at grade.
The technical solution of the utility model is the cutter of band streamline handle, and cutter hub is provided with the finger pressure section, comprises that finger pressure section rear end is a basic point terminad twisting formation, and the handle of a knife and the lever of described twisting formation are adaptive.Finger pressure section top is provided with the thumb pressure surface, and the thumb pressure surface is concave surface, and thumb pressure surface and thumb pad are adaptive.
The cutter of above-mentioned band streamline handle, wherein, described finger pressure section below is provided with forefinger and holds face, and it is V-shaped that forefinger is held face.
The cutter of above-mentioned band streamline handle, wherein, described lever is provided with two parts up and down, and upper-part is the palm lever, and palm lever lower end and twist mode handle of a knife top are adaptive; Lower member is a finger grip, and the finger grip upper end is adaptive with twist mode handle of a knife bottom, and palm lever upper end is symmetrical circular arc type with the finger grip lower end.
The cutter of above-mentioned band streamline handle, wherein, described knife back lines and palm lever upper end are circular arc streamline, and blade is circular arc type from point of a knife and knife plate bottom righthand side.
The cutter of above-mentioned band streamline handle, wherein, described lever end is processed into interior incisal bevel.
The utility model advantage and good effect are:
The finger pressure face is vertical with the knife back, enlarges the lifting surface area of finger pressure, can make stressed pressure point of the knife back and blade point of contact at grade, uses the Tool in Cutting thing more steady.

The specific embodiment
Please refer to shown in Fig. 1-5 cutter of band streamline handle; Comprise cutter hub 1, lever 2, finger pressure section 3, it is characterized in that: comprise that finger pressure section 3 rear ends are basic point terminad twisting formation, the handle of a knife 11 and the lever adaptive 2 of described twisting formation; Described finger pressure section 3 tops are provided with thumb pressure surface 31, and thumb pressure surface 31 is concave surface, and thumb pressure surface 31 is adaptive with thumb pad; Described finger pressure section 3 belows are provided with forefinger and hold face 32, forefinger hold 32 V-shaped; The described knife back 13 lines are streamlined with grasp handle 21 upper end circular arcs, and blade 15 is circular arc type from point of a knife 12 and knife plate 14 bottom righthand sides; Described lever end 2 ends are processed into interior incisal bevel; Described lever 2 is provided with two parts up and down, and upper-part is a palm lever 21, and palm lever 21 lower ends and twist mode handle of a knife 11 tops are adaptive; Lower member is a finger grip 22, and finger grip 22 upper ends and twist mode handle of a knife 11 bottoms are adaptive, and palm lever 21 upper ends and finger grip 22 lower ends are symmetrical circular arc type.
The cutter using method of band streamline handle is: hold the lever 2 on the handle of a knife 11, thumb press is on finger pressure face 31, and finger pressure face 31 is vertical with the knife back 13, and the power that acts on the knife back 13 passes to blade 15 point of contacts, owing to enlarged the area of finger pressure face 31; Owing to use cutter point of contact direction accurately reliable, therefore can effectively protect the people who uses cutter.
