Description

Technical Field

[0001] This utility model relates to a folding knife, and more particularly to a folding knife with a quick-change blade, which belongs to the field of utility knife technology. Background Technology

[0002] A craft knife is a type of knife used for art and handicrafts, primarily for cutting soft materials. It typically consists of a plastic handle and a blade, with a pull-out design. A few also have metal handles. The blade is usually beveled; when dull, it can be broken along the scored lines on the blade to create a new, sharp edge for easier use.

[0003] Existing knives are usually single-function, only able to perform one or two of the functions of a cutter, scraper, or safety utility knife. They are also very inconvenient to operate with either hand, and it is inconvenient to carry different types of knives separately. They are also prone to injury during the process of switching between them, making them unsafe to use.

[0004] Therefore, it is particularly necessary to provide a multi-functional knife that has a reasonable structural design, is safe and reliable, is easy to operate, and can meet the needs of multiple scenarios. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a folding knife with a reasonable structural design, safety and reliability, and the ability to quickly switch between a spatula and a utility knife, and to be easy to install and disassemble.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: This folding knife with quick-switchable blades includes a handle component, a blade holder, a blade head, and a blade. The blade holder is rotatably connected to the handle component. The blade head is provided inside the blade holder. The blade holder includes a left blade holder and a right blade holder connected to each other. The blade head includes a left blade head and a right blade head connected to each other. The blade is disposed between the left blade head and the right blade head. The feature is that it also includes a rotary button component, a spring, and a blocking component. The blade head is rotated by the rotary button component, which is disposed between the left blade holder and the right blade holder. The rotary button component contains a spring, and the rotary button component is provided with a blocking component that can block the blade for safety protection. The rotary button component and the blocking component can achieve bidirectional functional safety.

[0007] Preferably, this utility model also includes a locking mechanism, which is disposed between the left and right tool holders; by operating the locking mechanism, it locks against the left cover plate, preventing the tool holder from folding.

[0008] Preferably, the present invention also includes a rotary button for rotating the tool holder, the rotary button extending outside the handle component.

[0009] Preferably, the present invention also includes a screw and a plurality of screws, wherein the left tool holder and the right tool holder are connected by the screw, and the left cutter head and the right cutter head are connected by a plurality of screws.

[0010] Preferably, the present invention also includes anti-slip recesses, and anti-slip recesses are provided on the lower parts of both the left cover plate and the right cover plate.

[0011] Preferably, the handle component of this utility model includes a left cover plate, a right cover plate, a protective cover plate, and bolts. The left cover plate and the right cover plate are fixed together by bolts, and the protective cover plate is fastened to the upper part of the left cover plate and the right cover plate.

[0012] Preferably, the blocking component and the rotary button component of this utility model are integrated into one unit.

[0013] Compared with the prior art, this utility model has the following advantages and effects: the overall structure is reasonably designed, safe and reliable, and the conversion process is fast and stable. The blade is rotated into a shovel by the rotary button on the blade holder; the rotary button and the blocking part achieve bidirectional functional safety; the operating latch locks the cover plate, preventing the blade holder from folding, thus increasing safety; when the latch lock is retracted, the entire blade head can automatically spring back under the action of the spring inside the latch lock and the rotary button is operated; the blade can be replaced by screw one and multiple screws two, meeting usage requirements.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] Example

[0024] See Figures 1 to 7 This embodiment of a folding knife with quick-switchable blades includes a handle component 1, a blade holder 2, a blade head 3, a blade 4, a rotary button component 5, a spring 51, and a blocking component 52. The blade holder 2 is rotatably connected to the handle component 1. The blade head 3 is disposed inside the blade holder 2. The blade holder 2 includes a left blade holder 21 and a right blade holder 22 connected to each other. The blade head 3 includes a left blade head 31 and a right blade head 32 connected to each other. The blade 4 is disposed between the left blade head 31 and the right blade head 32. The blade head 3 is rotated by the rotary button component 5, which is disposed between the left blade holder 21 and the right blade holder 22. The rotary button component 5 contains a spring 51, and the rotary button component 5 is provided with a blocking component 52 that can block the blade for safety protection.

[0025] In this embodiment, the blocking member 52 and the rotary button member 5 are integrated; the specific structure of the rotary button member 5 can be selected and set according to different situations.

[0026] In this embodiment, the handle component 1 includes a left cover plate 11, a right cover plate 12, a protective cover plate 13, and a bolt 14. The left cover plate 11 and the right cover plate 12 are fixed together by the bolt 14, and the protective cover plate 13 is fastened to the upper part of the left cover plate 11 and the right cover plate 12.

[0027] In this embodiment, the locking mechanism 7 is located between the left tool holder 21 and the right tool holder 22; the rotating button 6 is used to rotate the tool holder 2, and the rotating button 6 extends to the outside of the handle component 1.

[0028] In this embodiment, the left tool holder 21 and the right tool holder 22 are connected by screw 23, and the left cutter head 31 and the right cutter head 32 are connected by multiple screws 33.

[0029] In this embodiment, anti-slip recesses 15 are provided at the lower part of both the left cover plate 11 and the right cover plate 12.

[0030] This embodiment features a folding knife with rapidly switchable blades, operating as follows: 1) Normally, it is a utility knife or paper cutter. The knife holder 2 has a rotating button 5. When pressed, the blade 4 rotates into a scraper. 2) To change the type of blade 4, the left blade head 31 and right blade head 32 are unscrewed using two screws 33. 3) The rotating button 5 and the blocking part 52 provide bidirectional safety. The blade head 3 rotates via the rotating button 5. After rotation, the locking part 7 retracts, locking the handle part 1 so that the knife holder 2 cannot be folded in the scraper state, increasing safety. When the locking part 7 retracts, the entire blade head 3 automatically springs back under the action of the spring inside the locking part 7 when the rotating button 5 is operated. 4) Pressing the rotating button 6 rotates the knife holder 2 into the inner cavity of the handle part 1 to quickly switch blades. At this time, it is in the folded state.

[0031] Based on the above description, those skilled in the art are already able to implement it.

[0032] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components.
