Description

Technical Field

[0001] The utility model relates to the technical field of kitchen tools, in particular to a detachable knife. Background Art

[0002] In daily life, knives are common kitchen tools for cutting vegetables. The handles and blades of existing knives are usually fixed by hammering with pins, and users cannot disassemble and assemble them. When cleaning, the gap between the handle and the blade is difficult to be effectively cleaned, and a large amount of dirt accumulates and breeds bacteria, which cannot guarantee the safety of users.

[0003] According to patent CN 218398217 U, a detachable tool includes a tool body and a tool handle. The tool body includes a blade and a connecting handle. The tool handle is provided with a mounting groove and a plug-in groove. A connecting rod mechanism is passed through the mounting groove. When the connecting handle is plugged into the plug-in groove, the tool handle is locked or unlocked with the connecting handle through the connecting rod mechanism.

[0004] The patent realizes a detachable connection between the knife body and the knife handle by setting a connecting handle on the knife body to be plugged into the knife handle. The connecting rod mechanism is set on the knife handle to penetrate the installation groove to lock and unlock the knife handle and the connecting rod mechanism. The connecting rod mechanism can ensure that the knife body is stably fixed on the knife handle to prevent the user from being injured due to the free separation of the knife body and the knife handle. If the user needs to separate the knife body from the knife handle, the connecting rod mechanism and the connecting handle are unlocked, and the knife body can be easily removed from the knife handle for cleaning and replacement, thereby preventing the knife from having sanitary dead corners, reducing the cost of maintenance and replacement, and being simple and convenient to operate. However, the knife handle in the patent is a whole, and it is not possible to clean the dirt in the knife handle. Utility Model Content

[0031] The back side of the first knife handle 411 is attached to the front side of the knife handle 3 , and the front side of the second knife handle 412 is attached to the front side of the knife handle 3 .

[0032] The surface of the positioning block 413 is slidably connected to the first sliding groove 414 and the positioning groove 415 .

[0033] For example 2, please refer to Figure 4-6 , and on the basis of the first embodiment, a positioning component 41 is further obtained.

[0034] The fixing assembly 42 includes a second slide groove 421, which is arranged in the second handle 412 near the top. A rectangular groove 422 is arranged on the right side of the second handle 412 near the top. A first connecting hole 424 is arranged on the left side of the inner wall of the rectangular groove 422. A connecting block 423 is fixedly connected in the second slide groove 421. A second connecting hole 425 is arranged on the right side of the connecting block 423 corresponding to the first connecting hole 424. A guide rod 426 is slidably connected in the first connecting hole 424. A fixing block 427 is fixedly connected to the surface of the guide rod 426 symmetrically. An L block 4211 is fixedly connected to the bottom of the fixing block 427. An L groove 429 is arranged in the second handle 412 corresponding to the L block 4211. A fixing groove 4213 is arranged on the right side of the positioning block 413. A spring 428 is symmetrically sleeved on the surface of the guide rod 426.
