Abstract

The utility model relates to a cutter. On the basis of the existing cutter handle, the cutter handle extends to a cutter surface. One part of the cutter handle which extends to the cutter surface extends to the direction of a cutter head, and the other part extends to the direction of a cutter edge. The part of the cutter handle on the cutter surface of part of the handle which extends to the direction of the cutter edge clamps the cutter surface, extends to the direction of the cutter edge and becomes thinner and thinner. Both surfaces of part of the cutter handle extending to the direction of the cutter edge are respectively provided with grooves, and three grooves which are arranged in order are arranged below the cutter handle; the grooves which are annular surround around the cutter handle for in about half a circle. A cutter tail under the cutter handle extends towards the tail part of the cutter handle for a certain distance.

Description

New-type cutter

Technical field the utility model relates to cutter, particularly new-type cutter.

The existing cutter of background technology does not meet mechanics and ergonomics principle, uses inconvenient.

Summary of the invention the utility model is a new-type cutter, and it redesigns the handle of cutter and cutter, makes it more meet mechanics and ergonomics principle, and is user-friendly.

Described cutter on the basis of existing cutter handle, extends on the knife face handle, extends to the handle on the knife face, and a part is extended to the cutter head direction, and a part is extended to the blade direction.

Part handle to the blade direction is extended makes the part of handle on knife face clamp knife face, and along with extending and attenuation gradually to the blade direction.

The two sides of the part handle that extends to the blade direction has a groove respectively, the direction of groove is identical with the bearing of trend of handle, when user's right hand is held described handle, thumb is put in the groove on the part handle that the blade direction is extended on the knife face left side, forefinger is put in the groove on the part handle that the blade direction is extended on knife face the right, the groove on the left side extends to the back of described handle always, and change direction gradually, extend back upper place to handle, and combine together with handle gradually, also extend to the back of handle at the groove on the right side always, and combine together with handle gradually, can make user's thumb and forefinger clamp knife face like this, can be more steady when using cutter, because finger is put in the groove, exert oneself before and after being convenient to during with cutter simultaneously.

On the part handle that the blade direction is extended, when the right hand is held cutter, the back of the groove that thumb is held, on the handle tail direction, being close to groove has one to be horizontal plane with the knife face, the part as ridge of projection, it is pasting groove always and is extending to the handle back upper place gradually, combine together with handle, it be used to hold thumb and with the approaching part palm of thumb, be convenient to during like this with cutter exert oneself downwards.

Part handle to the extension of cutter head direction, with the intersection of the knife back, the part of handle is dented, curved, on its back handle orientations, it is the part of projection, as small hill, this bag is positioned at the cutter head direction of the groove on the part handle that the blade direction is extended, and when the user held described handle like this, thumb and forefinger were put in respectively in the groove on the part handle of blade direction extension, and tiger just in time is positioned at the back of this bag, be convenient to cutter the time so firmly, thumb also can so also be convenient to firmly by the recess at handle and knife back intersection.

There are 3 tactic grooves the below of handle, and groove is annular, around the about half cycle of handle, combine together with handle gradually from depth to shallow in two of groove, 3 fingers except that thumb and forefinger can be held in these 3 grooves, can make like this hand more steady hold cutter.

Cutter tail under handle is not a straight line perpendicular to the knife back, cutter Caudad handle afterbody under the handle extends a segment distance, but some does not extend to the handle afterbody below handle, purpose is in order to make finger can hold handle, article also can be cut in the extension, and can use bigger power here, be convenient to cut hard object.
