Benefits of technology

This patent describes an improved cutting tool that has several technical features such as being securely locked when not in use or allowing for more flexibility in adjustment of its locking angle. It also includes a simplified mechanism for making it easier to fold up during storage. Overall, this new cutting tool provides better protection against injury from accidentally exposing it while still providing ease-of-use features.

Problems solved by technology

This patent describes a problem with existing folding knifters that require manual adjustment and locking mechanisms to secure their folds. These mechanisms also make them difficult to store safely due to their bulky size and complicated design. There is a need for a more efficient and effective solution to these issues.

example 1

[0033]As shown in FIGS. 1-3, a folding knife with multiple locking angles includes a knife handle 2, a knife body 1 pivotably coupled to the knife handle 2 at a first end 11, an angle adjusting mechanism, and a positioning mechanism.

[0034]The angle adjusting mechanism is fixedly disposed on the first end 11 of the knife body 1 and includes a plurality of locking structures configured to position the knife body 1 and the knife handle 2 at different angles. Each locking structure has at least one notch opening. The angle adjusting mechanism may have various forms. In the present embodiment, the angle adjusting mechanism is a cam 4. The angle adjusting mechanism may also be in the form of a circular plate having a plurality of circular holes functioning as notch openings. That is to say, the angle adjusting mechanism is not limited to the structure shown in the figures, other structures are contemplated.

[0035]The positioning mechanism is configured to select an angle between the knife bod

example 2

[0046]Referring to FIG. 8, the knife body 1 and the cam 4 may be disposed on one side of the knife handle 2, either on the left side or on the right side. Additionally, the positioning push button 5 may be positioned on one side of the knife handle 2, either on the left side or on the right side. This structure is easy to manufacture and intuitive to use.

example 3

[0047]FIGS. 8 and 9 illustrate another embodiment of the present invention. In this embodiment, a knife body 71 includes a knife blade 82 and a knife frame 81. The knife blade 82 is mounted on the knife frame 81. The knife body 71 is only example and does not limit the scope of the present invention. In other words, the knife body 71 may have any suitable form.

Abstract

A multi-angle positioned foldable knife includes a knife body (1), a handle (2) and a pin (3). The knife body (1) is pivotally connected with the handle (2) through the pin (3). A cam (4) is arranged on the connecting end of the knife body (1), and snap openings (41) on the outer edge of the cam are provided to position the knife body (1) at multi-angle relative to the handle (2). A positioning button (5) is arranged on the connecting end of the handle (2), and a snap edge (51) is provided on the interior end of the button (5). The snap edge (51) can connect with a snap opening (41) on the outer edge of the cam (4). Compared with prior art, the foldable knife has simple structure, controlled angle, safe use, convenient operation, simple preparation etc. The knife body (1) can be positioned at multi foldable position. Additionally, the rotation of the knife body (1) can be achieved only by pressing the button (5).
