Description

Combined plastic knife

Technical Field

The utility model relates to the technical field of plastic cutters, in particular to a combined plastic cutter.

Background

The steak knife is a common western-style food tableware, the knife part of the steak knife is provided with a plurality of fine teeth to cut meat, when eating western-style food, the common tableware is usually used, the current steak plastic knife is of an integral structure through injection molding, the plastic knife is molded at one time in the injection molding process, the knife head and the handle are all made of the same thermoplastic material, the materials and the colors of the knife head and the handle are uniform, the combination and the collocation cannot be carried out, and the steak plastic knife is monotonous and unattractive.

Disclosure of Invention

The utility model aims to provide a combined plastic knife which is firmly combined by independent knife heads and handles and is various and attractive.

The utility model provides a combined plastic knife which comprises a knife head and a handle, wherein the knife head vertically and downwards extends to form a flat inserting part, clamping parts are symmetrically arranged on the left side and the right side of the inserting part, an inserting hole which is used for accommodating the inserting part to extend into and accommodating the clamping part to clamp is formed in the upper end of the handle, and the inserting part and the clamping part enter the inserting hole in a heat expansion and cold contraction mode.

Further, a reinforcing rib with two unfolded wings is arranged on one side, far away from the cutter teeth, of the cutter head.

Furthermore, the lower end of the cutter head is equidistantly provided with racetrack-shaped convex parts.

Further, the grip is composed of a straight section with the upper side connected with the cutter head and an arc-shaped section with the lower side, and the thickness of the straight section is larger than that of the arc-shaped section.

Further, the tail of the arc section is gradually narrowed and tilted backwards.

Further, the left side and the right side of the handle are symmetrical in outline and incline from top to bottom, and the lower side of the handle is arc-shaped.

The combined plastic knife firmly combines the independent knife head and the handle in a thermal expansion and cold contraction mode, and is various and attractive as a whole; the tool bit and the grip are respectively contracted and expanded, and then the insertion part and the clamping part of the tool bit are arranged in the jack, so that the tool bit is difficult to pull out at normal temperature; the cutter tooth section of the cutter head is thinner, and the cutter tooth section is easy to break when used for cutting steak and the like, and the structural strength of the cutter tooth section is enhanced through the reinforcing rib; the two fingers can pinch the convex part, so that the hand feeling is enhanced, and the force is convenient to apply; the straight section connected with the cutter head needs enough thickness to improve the structural strength, the arc section can enable the hand feeling to be better, the cutter cannot be abrupt, the tail of the arc section is gradually narrowed and tilted backwards, the state of holding the arc section is met when the cutter head is tilted backwards, and the tail can be attached to a hand; the outline of the handle can effectively prevent the handle from being taken off.

Description of the embodiments

Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, the utility model provides a combined plastic knife, which comprises a knife head 1 and a handle 2, wherein the knife head and the handle are of an integrated structure, the knife head and the handle can be respectively injection molded, so that the materials and colors of the knife head and the handle can be different, the combined plastic knife is more diversified and attractive, the choice of the materials of the handle can pay attention to the improvement of hand feeling, the knife head 1 vertically and downwards extends to form a flat plug part 5, the left side and the right side of the plug part 5 are symmetrically provided with clamping parts 6, the upper end of the handle 2 is provided with a jack 2.1 which is provided with a clamping groove which is used for accommodating the clamping parts and is used for clamping the plug part 5, the clamping parts 6 enter the jack 2.1 in a heat expansion and cold contraction mode, the knife head and the handle are respectively contracted and expanded in heat expansion mode, the plug part and the clamping part of the knife head are contracted a little, the jack expansion point of the handle is arranged in the jack, and the plug part and the clamping part are difficult to be pulled out under normal temperature.

The cutter tooth section of the cutter head is thinner, the cutter tooth section is easy to break when used for cutting steak and the like, the structural strength of the cutter tooth section is enhanced through the reinforcing rib, and the side, away from the cutter tooth, of the cutter head 1 is provided with the reinforcing rib 3 with two unfolded wings.

The lower end of the tool bit 1 is equidistantly provided with racetrack-shaped convex parts 4. The number of the preferred convex parts is 4, and when a user holds the handle, two fingers can pinch the convex parts, so that the hand feeling is enhanced and the force is conveniently applied.

Referring to fig. 3, in order to improve the structural strength of the joint and the hand feeling of the hand, the grip 2 is composed of a straight section with the upper side connected with the cutter head 1 and an arc section with the lower side, and the thickness of the straight section is larger than that of the arc section, the straight section connected with the cutter head needs enough thickness to improve the structural strength, the arc section can make the hand feeling better, the tail of the arc section is gradually narrowed and tilted backward, the backward tilting is set to be in accordance with the state of holding the arc section, and the tail can be in contact with the palm.

Referring to fig. 2, the contours on the left and right sides of the grip 2 are symmetrical and incline from top to bottom, the contour on the lower side of the grip 2 is arc-shaped, and the contour arrangement of the grip can effectively prevent the grip from being out of hand.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
