Description

Hand-held cutter and its wheel cutter

This creation is related to hand-held cutters; in particular, it refers to a hand-held cutter with a wheel cutter.

Common cutters, such as utility knives or pen knives, use blades to cut objects, but when using a cutter with blades to cut objects, the cutting direction must be the same as the extension direction of the blade, so as not to cause uneven cuts. .

There are also manufacturers in the market that have introduced a cutter with a wheel cutter. One end of the cutter is equipped with a wheel cutter. When cutting objects with a rolling wheel cutter, the cutting direction can be changed according to needs. It can be used not only for straight cutting, but also for straight cutting. Cutting in curved line segments.

The existing cutters are designed to be easy for users to operate, and the blades of the wheel cutters are too sharp, which often leads to accidental or improper use of the blades. Therefore, the existing cutter with a wheel cutter is still not perfect and needs to be improved.

In view of this, the purpose of this creation is to provide a hand-held cutter and its wheel cutter, which can have cutting ability and is not easy to cut the user.

In order to achieve the above-mentioned purpose, this creation provides a hand-held cutter, which includes a handle and a round knife, wherein the round knife is pivoted at one end of the handle; the round knife has a ring Shaped blade, the blade is composed of two tapered surfaces; on the axial section of the wheel cutter, an included angle is formed between the two tapered surfaces, and the angle of the included angle is between 45 and 60 degrees.

The wheel cutter of a hand-held cutter provided by this creation has an annular blade portion composed of two cone surfaces; on the axial section of the wheel cutter, an included angle is formed between the two cone surfaces , The angle of the included angle is between 45 and 60 degrees.

The effect of this creation is that the design of the angles of the above-mentioned wheel cutter not only provides the user with a good cutting ability when cutting objects by hand, but also makes it difficult to cut the user.

The second handle 36 has at least one second abutting portion 42, 44, and the at least one second abutting portion 42, 44 is used to abut the corresponding at least one first abutting portion 32, 34. In this embodiment, there are two second abutting portions 42, 44, of which one second abutting portion 42 is formed on the connecting rib 40 and located at one end of the connecting rib 40. In addition, the second handle 36 further includes a sealing plate 46 connected between the two side plates 38, and the sealing plate 46 forms another second abutting portion 44 at an end close to the first handle 22.

In order to prevent the first handle 22 and the second handle 36 from loosening in the expanded state or the collapsed state, in this embodiment, the hand-held cutter further includes a positioning mechanism disposed on the first handle 22 and the second handle. Between the handles 36, the positioning mechanism can fix the relative positions of the first handle 22 and the second handle 36 when the first handle 22 and the second handle 36 are in the expanded state or the collapsed state.

In more detail, the first handle 22 is provided with a positioning member 50. In this embodiment, the positioning member 50 takes a spring positioning pin as an example and is disposed in a pin hole 222. The positioning member 50 includes at least one positioning body. 52 and at least one spring 54, the number of at least one positioning body 52 is two and is located at two On the opposite side, each positioning body 52 has an arc surface. The second handle 36 has at least one positioning groove 48 on at least one wall surface of the accommodating space 38 a. In this embodiment, two opposite wall surfaces of the accommodating space 38 a both have a positioning groove 48. The positioning member 50 and at least one positioning slot 48 constitute a positioning mechanism. Each of the positioning grooves 48 has a first groove section 482 and a second groove section 484. The first groove section 482 and the second groove section 484 are connected and located on a straight line. The second groove section 484 has an open end 484a. , The open end 484a communicates with the opening 38b. Each of the positioning grooves 48 is substantially parallel to the extending direction of the connecting rib 40. The two groove sections of the positioning groove 48 communicate with the opening 38b, which facilitates the procedure when the second handle 36 is released from the film.

6 and 7, when the first handle 22 and the second handle 36 are in the expanded state, the two first abutting portions 32, 34 on the first handle 22 abut the second handle 36, respectively The second abutment portion 42 in the accommodating space 38a and the second abutment portion 44 on the sealing plate 46, the first abutment portion 32, 34 and the second abutment portion 42, 44 abut to facilitate the user's implementation force. In addition, the spring 54 of the positioning member 50 pushes against the two positioning bodies 52, so that the two positioning bodies 52 respectively extend into the first groove section 482 of the two positioning grooves 48, thereby achieving the purpose of positioning and fixing the first The relative position of the handle 22 and the second handle 36.

Please cooperate with FIGS. 8-10. When the first handle 22 and the second handle 36 are in the collapsed state, at least a part of the first handle 22 enters the accommodating space 38a through the opening 38b, and the wheel cutter 10 is housed in the accommodating space 38a. In addition, the spring 54 of the positioning member 50 pushes against the two positioning bodies 52, so that the two positioning bodies 52 respectively extend into the second groove section 484 of the two positioning grooves 48, thereby achieving the purpose of positioning and fixing the first The relative position of the handle 22 and the second handle 36.

When the user wants to expand the first handle 22 and the second handle 36, he can grasp the first shallow groove 242 and the second shallow groove 382 with his fingers, and expand the first handle 22 and the second handle 36 relatively, namely Can be restored to the expanded state.
