Description

Paring knife

The utility model relates to daily living article, specifically is a kind of paring knife.

The melon and fruit peeling has become the preceding requisite step of the edible melon and fruit of people.Traditional skinner one is the common fruit cutter, the one, and melon and fruit is removed the peel special-purpose paring knife, the plane of peeling.When reality was used, above-mentioned two kinds of instruments all existed defective to some extent.The common fruit cutter that is made of blade and the hilt blade depth and the full armrest of uniformity coefficient firmly that advance skin is in use grasped, and is difficult to control, and the effect of peeling is often not ideal enough.Special-purpose paring knife, peel and dig generally by hilt, blade, header board constitutes, header board and blade lay respectively on two planes of V font, header board and blade are for being fixedly connected, header board is as the benchmark in when cutting, grasp the depth that blade advances skin for people and played certain help, but because header board is a stationary structure, and be to lean against the melon and fruit surface as benchmark, must increase the resistance of cutting movement during use, use very effort, simultaneously, also easy damaged pericarp during cutting movement, bad grasp and use, this also is a paring knife, peel and dig a reason of extensively not popularizing.

The purpose of this utility model just provides a kind of paring knife, can overcome present paring knife, peel and dig the defective that structurally exists, and is more convenient to use, better effects if.

The technical solution of the utility model is: comprise hilt and the blade that is contained on the hilt, wherein the rolling shaft that can freely rotate is housed in blade the place ahead of blade, the axis of rolling shaft parallels with the blade of blade, and the angle between the sword face of tangent line that is connected with point of a knife blade rolling shaft and blade is 90 °≤θ＜180 °.

According to technique scheme, the utility model utilizes the benchmark of rolling shaft as cutting, through on probation, compared with above-mentioned header board as benchmark, the depth of easier control and grasp cutting, rolling shaft is as benchmark simultaneously, and in working angles, rolling shaft rolls on the melon and fruit surface, little compared with header board in melon and fruit surface resistance to sliding, use more laborsavingly, be easy to cut, also can not damage the melon and fruit surface simultaneously.

The formula that the is connected as one structure of rolling shaft of the present utility model and blade or be fixedly connected or grafting, clamp connected is movable connects, structure and manufacturability according to blade, rolling shaft and blade are made an integral body or be fixed into an integral body, promptly become a special-purpose paring knife, simple in structure, easy to use.If rolling shaft is made an accessory, by being contained in, the movable connecting mode of its grafting, clamp connected constitutes a paring knife on the blade when needing, can realize the function of peeling, when not required it is taken off, can realize the function of universal cutter.One-object-many-purposes makes things convenient for the user.

Rolling shaft of the present utility model is the axle of a rolling or is with roller in the activity of the two ends of an axle, to constitute different embodiment, can achieve the above object equally.

So the paring knife that the utility model provides is simple in structure, reasonable in design, uses laborsaving, convenience, and good with result of use, and the scope of application is wide, can satisfy people's different instructions for uses.

Describe in detail below in conjunction with the embodiment accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents structural representation of the present utility model, is a kind of embodiment;

The A-A profile of Fig. 2 presentation graphs 1.

Referring to accompanying drawing, constitute one universal cutter by hilt (1) and blade (2), one axis of rolling that can freely rotate (3) is housed in blade the place ahead of blade (2), the axis of the axis of rolling (3) parallels with the blade of blade (2), and the angle theta between the tangent line that the point of a knife with blade (2) of the axis of rolling (3) is connected and the sword face of blade (2) is about 140 °

Claims (3)

1, a kind of paring knife, comprise hilt and the blade that is contained on the hilt, it is characterized in that being equipped with the rolling shaft (3) that can freely rotate in blade the place ahead of blade (2), the axis of rolling shaft (3) parallels with the blade of blade (2), and the angle between the tangent line that the point of a knife with blade (2) of rolling shaft (3) is connected and the sword face of blade (2) is 90 °≤θ＜180 °.

2, paring knife according to claim 1 is characterized in that the formula that the is connected as one structure of rolling shaft (3) and blade (2) or is fixedly connected or grafting, clamp connected is movable connects.

3, paring knife according to claim 1 is characterized in that rolling shaft (3) is an axis of rolling or is with roller in the activity of the two ends of an axle.
