Description

Handheld Knife Sharpener

technical field

The utility model relates to a hand-held knife sharpener, especially a portable knife sharpener which can sharpen a knife (such as a fruit knife, a kitchen knife, a tailor knife, etc.) at one end and cut hard objects (glass, tile, etc.) at the other end. .

Background technique

Looking at the current market ecology, there are various knife sharpeners to choose from, and their types and formations are varied and numerous. For example, the approved application case No. 88221039 of Taiwan, China discloses a simple portable knife sharpener. Knife sharpener, which consists of a sharpener body, a knife seat, a knife and a side cover, is equipped with two accommodation chambers, each of which has a cross knife set. Put it in the knife set, and move the knife to be sharpened back and forth, so as to implement sharpening. But the shortcoming of this knife sharpener is that the weight is too heavy, and it loses the convenience of being easy to carry. Moreover, because the knife sharpener is provided with a handle, one hand moves the knife back and forth, and a part of the friction force generated at this time is caused by the hand. Absorption, part of which is absorbed by the body, but there is no support to absorb its front and rear component forces, resulting in unexpected displacement of the body following the magnitude of the applied force, and the resulting danger is out of the question.

In response to various tailoring needs, different knives have been developed. Whether industrial or commercial, knives have their roles, ranging from scissors and utility knives used by general companies to household kitchen knives, fruit knives, tailor knives or as large as Scissors in sheet metal factories, etc., are all the same. However, it is unavoidable that no matter what kind of hard material the knives are made of, they will wear out and become unusable. Therefore, it is our goal to make the knives reusable enough to maximize economic benefits. However, looking at the knife sharpeners sold on the market, if they are distinguished according to the power source, there are many kinds of sharpeners that use electricity, air pressure, hydraulic pressure or natural sharpening stones. However, there is no knife sharpener that can be widely used in various industries.

Utility model content

The technical problem to be solved by the utility model is to provide a hand-held knife sharpener with wide application range, safe operation, light texture and easy to carry in view of the deficiencies of the prior art.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a hand-held knife sharpener, including a handle; one end of the handle is provided with a sharpening seat, and a sharpening seat is provided on the sharpening seat; The other end of the handle is provided with a roller cutting mechanism.

Compared with the prior art, the beneficial effect of the utility model is that: one end of the utility model is provided with a sharpening blade, and the other end is provided with a roller type cutting mechanism, so that the utility model can not only grind various knives, but also cut glass and mirror surfaces Hard objects such as , acrylic and tiles meet the needs of people's lives; and the utility model deliberately reduces the volume and weight, making the utility model easier to carry and use.

Detailed ways

In conjunction with the drawings, the preferred embodiments of the present invention are described in detail as follows:

Please refer to Fig. 1, which is a three-dimensional view of the hand-held knife sharpener of the present invention, which includes:

One is the handle 10 of the hand grip part, and one is connected to the sharpening seat 20 at one end of the handle 10. The sharpening seat 20 is provided with a sharpening edge 201, and the sharpening edge 201 is bonded to a plane of the sharpening seat 20. One end of the sharpening seat 20 is provided with a disc-shaped retaining ring 202 protruding from the handle 10, and the retaining ring 202 is interposed between the sharpening seat 20 and the handle 10, so when the user sharpens the knife, the retaining ring 202 That is to cover the hands of the user to prevent the user from operating accidentally and achieve the purpose of safety.

In order to conform to the ergonomics of the palm, the appearance of the handle 10 is set in an arc shape; and, the two sides of the handle 10 are provided with a number of grooves 101, so when sharpening the knife, the palm and fingers can firmly hold the knife. The knife sharpener is held, as shown in Figure 2. In this embodiment, the preset user is a right-handed user who holds the handle 10 with the thumb and four fingers, and then uses the sharpener on the sharpening seat 20 to hold the sharpener. The acute angle of the blade 201 performs reciprocating grinding along the front surface of the tool to be sharpened, and since the sharpened blade 201 has several acute angles 201A and 201B for grinding, the user can choose any acute angle according to his preference.

Please refer to Fig. 3A, another function of the present utility model is to cut hard objects, so one end of the handle 10 is provided with a roller-type roller-type cutting mechanism 30, and the roller-type roller-type cutting mechanism 30 includes at least one fixed roller. Seat 301, a cutting roller 302 and a bearing 303, as shown in Figure 3B, because the center of this cutting roller 302 is provided with a bearing 303, thereby be fixed on this roller fixing seat 301, implement rolling and cut hard object simultaneously; Referring to Figure 3C, in order to make the utility model sharp and durable, the angle Θ of the cutting roller 302 wheel surface is designed to be between 90 degrees and 120 degrees, please refer to the implementation shown in Figure 4 For example, the figure also presupposes that the user is a right-handed operator, the thumb presses the grip groove 102, and the four fingers hold the handle 10 to cut the object to be cut. The roller fixing seat 301 is also a It is made of hard metal, and it is pointed at the place where the roller 302 is pivoted, so as to facilitate visual inspection during operation, and when cutting, an auxiliary mechanism can be installed on the object to be cut, in order to achieve the desired effect, the auxiliary mechanism It can be a linear walking mechanism or as a pullover for linear motion.

From this point of view, the utility model "Handheld Knife Sharpener" does have the utility of grinding knives and cutting hard objects (glass, tiles), and has the characteristics of lightness, portability and safety.
