Description

Technical Field

[0001] The utility model relates to the technical field of knives, in particular to a knife with a replaceable clavicle. Background Art

[0002] Knives are divided into two categories: straight-handled knives (non-foldable, such as kitchen knives for home use, hunting knives for outdoor use, etc.) and folding knives. Folding knives are mainly used for some daily delicate work and are easy to carry. However, in the past, folding knife products either adopted a sliding spring without lock or a back lock structure. Since the design structure of the blades of the two designs is also different, it is impossible to switch between the locked and unlocked functions, and it is impossible to meet different usage scenarios at the same time. Utility Model Content

[0003] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects of the prior art, a small knife with a replaceable clavicle is provided. The unique structural design can change the structure of the entire knife by replacing and combining two different locking back bones or non-locking back bones without changing the blade, thereby realizing the switching between locked and non-locked, thereby meeting different usage scenarios.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A knife with a replaceable clavicle comprises a handle and a blade rotatably connected to the handle, the handle being provided with a locking spine or a non-locking spine, the blade being provided with a full-stop locking tip and a half-stop locking tip, the locking spine being provided with a first locking position matched with the full-stop locking tip and the half-stop locking tip, the inner angle of the first locking position being a right angle, the non-locking spine being provided with a second locking position, the inner angle of the second locking position being an obtuse angle.

[0006] Preferably, a blade connecting portion connected to the handle is provided at the end of the blade, and a clamping groove adapted to the end of the locking spine and the end of the non-locking spine is provided on the blade connecting portion.

[0007] Preferably, the full-stop locking tip is arranged at the upper end of the blade connecting portion, and the half-stop locking tip is arranged at the right end of the blade connecting portion.

[0008] Preferably, a latch through hole for a latch to pass through is provided at the center of the blade connecting portion, and the knife handle is rotatably connected to the blade connecting portion via the latch.

[0009] Preferably, the locking spine and the non-locking spine are both embedded in the inner side of the upper end of the handle.

[0010] Preferably, a blade groove matching the blade is formed on the inner side of the bottom of the knife handle.

[0011] By adopting the above technical scheme, the utility model provides a knife with replaceable clavicle, which has the following beneficial effects: the handle of the knife is provided with a locking spine or a non-locking spine, the blade is provided with a full-stop locking tip and a half-stop locking tip, the locking spine is provided with a first locking position matched with the full-stop locking tip and the half-stop locking tip, the inner angle of the first locking position is a right angle, the non-locking spine is provided with a second locking position, the inner angle of the second locking position is an obtuse angle, and the unique structural design can be adopted to realize the replacement of the knife without changing the blade. By replacing and combining two different locking back bones or non-locking back bones, the structure of the entire knife can be changed, and locking and non-locking can be switched. When used lightly, such as opening express deliveries, peeling fruits, etc., the non-locking structure of the non-locking back bone is harmonious and convenient. When used heavily, the locking back bone can be replaced to achieve a locked structure, and even the half-stop state has a locked closure to prevent the blade from closing and hurting the hand. It is safer and suitable for outdoor use. At the same time, by setting a half-stop locking tip and combining it with a locking back bone, the blade can be locked when it is half closed, thus meeting different usage scenarios.
