Further, the knife handle is a wood handle.

Further, the handle becomes progressively wider from the end near the blade to the end away from the blade.

Furthermore, the corner of the L-shaped blade part adopts a circular arc angle for transition.

Further, the head edge part is of a convex arc structure.

Further, the length of the knife handle is 8-12cm, the length of the blade is 18-22cm, and the widest position of the blade is 6-10 cm.

Further, a protective shell is detachably arranged on the blade.

Furthermore, the protective shell is provided with a blocking edge matched with the profile of the blade, and the protective shell is connected with the blade in a clamping manner.

Furthermore, a clamping column is arranged on the protective shell, and a clamping hole is formed in the blade in a matched mode.

Furthermore, a rubber sleeve with a clamping edge at the end part is fixedly arranged on the clamping column.

The technical scheme of the utility model has the following beneficial effects:

1. the blade of the utility model is gradually widened from thin to wide, thus enhancing the bearing capacity of the tool knife and enabling the tool knife to exert force more easily, and the blade adopts a structure similar to a sickle, thus realizing the action of gathering and harvesting, harvesting lettuce and having high working efficiency;

2. the two sides of the cutter head of the blade are provided with the cutting edges, so that the practicability is higher, the application range is changed, and the tool knife is not long, so that the tool knife is easier to carry compared with harvesting tools such as sickles and the like;

3. the utility model combines the characteristics of various tools, is convenient, light, portable, easy to exert force and strong in bearing capacity, and greatly increases the harvesting effect, thereby playing a great role in the process of harvesting lettuce.

Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the utility model. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, lettuce harvest tool knife described in this embodiment, including handle of a knife 1 and blade 2, blade 2 widens gradually from the one end that is close to handle of a knife 1 to the one end of keeping away from handle of a knife 1, make blade 2 exert oneself more easily, blade 2 is provided with hook 201 in the one end of keeping away from handle of a knife 1 and thus make blade 2's whole present to be the L shape, present the structure similar with the hook, it gathers the ability of closing to reap to have increased, it comes to reap lettuce, high efficiency, the inboard of blade 2 is provided with L shape cutting part 202, the tip of blade 2 is provided with head cutting part 203, connect through transition cutting part 204 between L shape cutting part 202 and the head cutting part 203, adopt the structure of many cutting parts, make its function richer, can satisfy different operation requirements, application scope is wider.
