Description

Technical Field

[0001] The utility model belongs to the technical field of cutters, in particular to a lettuce knife. Background Art

[0002] The main edible part of lettuce is its fleshy tender stems, which can be eaten raw, served cold, fried, dried or pickled. The tender leaves are also edible. In daily life, people need to use knives to process them.

[0003] In the prior art, Chinese design CN202230193883.8 discloses a paring knife. The structure of this knife is similar to that of a conventional lettuce peeler on the market. This knife can only be used to plan the lettuce. However, in order to facilitate the processing of the lettuce, in actual use, other knives are needed to cut and scrape the lettuce. This increases the number of steps for the user to operate, and the user needs to put down the lettuce peeler and pick up other knives, which is inconvenient.

[0004] Therefore, a knife is needed that can directly cut, score and shave the lettuce. Summary of the Invention

[0008] The present invention is further configured as follows: the limiting component is circular, and the outer end of the limiting component is bent toward the outer end surface of the blade.

[0009] The utility model is further configured as follows: a portion of the blade back protrudes outward to form a mounting portion, and the limiting component is mounted on the edge of the mounting portion.

[0010] The present invention is further configured such that: the limiting component is arranged in an arc shape.

[0011] The utility model is further configured as follows: the outer end of the blade is protruded to form a blade tip.

[0012] The utility model is further configured such that: the cutter head, the blocking component and the limiting component are all fixed by welding.

[0013] The utility model is further configured as follows: the outer end of the cutter head is provided with a through hole.

[0014] The utility model is further configured as follows: a fixing rod is provided at the tail of the blade head, the fixing rod axially passes through the handle and the tail is bent to form a fixing end, and the end of the fixing end penetrates the end surface of the handle; or

[0015] A fixing rod is provided at the tail of the cutter head. The fixing rod is bent at the tail after axially passing through the handle to form a fixed end. A limiting groove is provided on the end surface of the handle, and the fixed end is fixed in the limiting groove.

[0016] The utility model is further configured as follows: the tail of the blade head is embedded in the handle.

[0017] The utility model is further configured as follows: the length of the planing area is greater than the length of the operating area; and the blade is configured in an inwardly concave arc shape.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the planing area and the operating area are directly arranged on the blade, so that one lettuce knife can directly cut, scratch and plan lettuce, which is convenient for users to operate, low in cost and high in efficiency.

[0027] The present invention will be further described below with reference to specific embodiments of the present invention:

[0028] See also Figures 1 to 5 As shown, a lettuce knife comprises a handle 1 and a blade head 2 arranged on the handle 1, the blade head 2 comprises a blade back 21 and a cutting blade 23, a blocking component 3 arranged on the blade back 21, a limiting component 4 is provided on the portion of the blade 23 close to the handle 1, a planing area 5 is formed between the limiting component 4 and the blade 23, the blocking component 3 is located above the planing area 5, and the blade 23 extends out of the area of ​​the limiting component 4 to form a cutting and scratching operation area 6; the planing area 5 and the operation area 6 are directly provided on the blade 23, so that a lettuce knife can be used to directly cut, scratch and plan lettuce, which is convenient for users to operate, low in cost and high in efficiency.

[0029] At the same time, in this embodiment, the length of the planing area 5 is greater than the length of the operating area 6, which can avoid the operating area 6 being too heavy and affecting the feel of use. At the same time, the length of the operating area 6 does not need to be too long in actual use to achieve cutting and scratching operations.

[0030] In order to facilitate cutting of lettuce, the blade 23 can be set to be a concave arc. The arc can be a regular arc, or an irregular or wavy arc, all of which are within the protection range.

[0031] In this embodiment, the limiting component 4 is circular, and the outer end of the limiting component 4 is bent toward the outer end face of the blade 23. The limiting component 4 is preferably a component with a circular cross-section. Combined with the bending setting, the planing area 5 can be planed more smoothly, and the limiting component 4 can be smoother when guiding.

[0032] The blade back 21 partially protrudes outward to form a mounting portion 22, and the limiting component 4 is installed on the edge of the mounting portion 22; the limiting component 4 is arranged in an arc shape; the limiting component 4 facilitates the collection of the cut skin and prevents the skin from extending onto the user's clothes.

[0033] In order to facilitate the user to scratch or pierce the lettuce, the outer end of the blade 23 is protruded to form a blade tip 24.

[0034] The cutter head 2, the blocking component 3 and the limiting component 4 are all fixed by welding, which facilitates assembly and production.

[0035] At the same time, a through hole 25 is provided at the outer end of the knife head 2, and the through hole 25 serves to hang the lettuce knife. When not in use, the lettuce knife can be hung on the hook for storage.

[0036] In this embodiment, in order to facilitate the installation of the blade head 2 and the handle 1 and prevent them from loosening after installation, the following structure can be used to fix the two:

[0037] Structure 1:

[0038] A fixing rod 26 is provided at the tail of the cutter head 2. The fixing rod 26 is bent at the tail after axially passing through the handle 1 to form a fixed end 27. The end of the fixed end 27 penetrates the end surface of the handle 1. The end of the fixed end 27 penetrates the handle 1 to limit the relative rotation of the cutter head 2 and the handle 1.

[0039] Structure 2:

[0040] A fixing rod 26 is provided at the tail of the cutter head 2. The fixing rod 26 is bent at the tail after axially passing through the handle 1 to form a fixed end 27. A limiting groove is provided on the end surface of the handle 1. The fixed end 27 is fixed in the limiting groove. The cooperation between the limiting groove and the fixed end 27 limits the relative rotation of the cutter head 2 and the handle 1.

[0041] Structure three:

[0042] The tail of the blade head 2 is embedded in the handle 1. The handle 1 is made of wood. The blade head 2 is made of metal. The tail of the blade head 2 can be directly embedded in the handle 1, or the handle 1 can be directly made of metal. The blade head 2 and the handle 1 are welded and fixed.

[0043] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
