Description

Technical Field

[0001] The utility model relates to the technical field of tools, and more precisely, to a tool. Background Art

[0002] The tool body of traditional tools is generally made of a single material, such as steel knives, ceramic knives, etc. The tool body is provided with a pin body, and the pin body is connected to the handle. This connection method results in a relatively large volume, poor integrity, and low connection stability, and the reliability for users to use is relatively poor. Content of the Utility Model

[0003] Aiming at the deficiencies and defects of the prior art, a tool with a compact structure, good overall performance, and durability and stability is provided.

[0004] A tool, comprising:

[0005] A tool body, with a cutting edge provided at the lower end of the tool body, a connecting portion provided at the upper end of the tool body, a plurality of holes provided in the connecting portion, and a notch provided in the connecting portion, and the notch exposes the upper end surface of the tool body;

[0006] A tool holder with a handle, and the tool holder is integrally embedded with the connecting portion by an integral molding method;

[0007] The connecting portion is provided with a plurality of holes, and a connecting body penetrating into the holes is formed on the tool holder;

[0008] A limiting portion entering the notch is formed on the tool holder, and the limiting portion supports the rear end surface of the tool body and the notch end surface of the connecting portion.

[0009] After adopting the above structure, compared with the prior art, the tool of the utility model has the following advantages: by integrally embedding the connecting portion of the tool holder and the tool body by an integral molding method (such as an injection molding method), there is no need to use connecting parts (such as screws, etc.) for connection, the tool body and the tool holder are more integral, the structure is compact, and the aesthetics is better;

[0010] A connecting body penetrating into the holes is formed on the tool holder, and both ends of the connecting body are integral with the tool holder. The connecting body and the holes form a blocking fit, reducing the relative movement between the tool body and the tool holder, improving the safety and durability during use, and providing stronger structural stability.

[0011] A limiting portion entering the notch is formed on the tool holder, and the limiting portion can support the connecting portion and the rear end surface of the tool body. The vertical stress performance of the tool body is better, and further reduces the relative movement between the tool body and the tool holder, improving the durability and stability.

[0012] As an improvement of the utility model, the connecting portion is arranged in a structure extending along the path of the cutting edge.

[0013] As an improvement of the present utility model, several of the said hole bodies are evenly distributed along the length direction of the connecting part.

[0014] As an improvement of the present utility model, the number of the notches is two, one of which is arranged at the front end of the connecting part and the other is arranged at the tail end of the connecting part. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0023] Please refer to Figures 1-5 as shown, a tool, comprising:

[0024] A tool body 1, a cutting edge 1.1 is arranged at the lower end of the tool body 1, a connecting part 1.2 is arranged at the upper end of the tool body 1, several hole bodies 1.21 are arranged on the connecting part 1.2, and a notch 1.22 is arranged on the connecting part 1.2, and the notch 1.22 exposes the upper end surface of the tool body 1;

[0025] A tool holder 2 having a handle 2.1, and the tool holder 2 and the connecting part 1.2 are integrally embedded by an integral molding method;

[0026] Several hole bodies 1.21 are arranged on the connecting part 1.2, and a connecting body 2.2 penetrating the hole bodies 1.21 is formed on the tool holder 2;

[0027] A limiting part 2.3 is formed on the tool rest 2 and enters the notch 1.22. The limiting part 2.3 supports the rear end face of the tool body 1 and the end face of the notch 1.22 of the connecting part 1.2.

[0028] By integrally molding and inlaying the connecting part 1.2 of the tool rest 2 and the tool body 1 (such as by injection molding), there is no need to use connecting parts (such as screws) for connection, making the tool body 1 and the tool rest 2 more integral and having better aesthetics;

[0029] A connecting body 2.2 that penetrates into the hole body 1.21 is formed on the tool rest 2. Both ends of the connecting body 2.2 are integral with the tool rest 2. The connecting body 2.2 and the hole body 1.21 form a blocking fit, reducing the relative movement between the tool body 1 and the tool rest 2, improving the safety and durability during use, and providing stronger structural stability.

[0030] A limiting part 2.3 that enters the notch 1.22 is formed on the tool rest 2. The limiting part 2.3 can support the connecting part 1.2 and the rear end face of the tool body 1, making the vertical force-bearing performance of the tool body 1 better, and further reducing the relative movement between the tool body 1 and the tool rest 2, improving durability and stability.

[0031] Please refer to Figure 2 As shown, the connecting part 1.2 is arranged in a structure that extends in an arc along the path of the cutting edge 1.1.

[0032] In this embodiment, the cutting edge 1.1 is arranged in an arc path with a gradually decreasing height from the front end to the tail end.

[0033] Please refer to Figure 6 As shown, this is the second embodiment of the present application. In this embodiment, the rear end face of the connecting part 1.2 can also be set to a serrated structure, which can further increase the connection stability after being inlaid with the tool rest 2.

[0034] A plurality of the hole bodies 1.21 are uniformly distributed along the length direction of the connecting part 1.2. After the above improvement, the hole bodies 1.21 are uniformly distributed along the length direction of the connecting part 1.2. After the connecting body 2.2 penetrates into the hole bodies 1.21, the formed connection structure is uniformly distributed along the length direction of the connecting body 2.2, increasing the connection positions to make the connection firm and reliable, and further improving durability and stability.

[0035] Please refer to Figures 1-5 As shown, the number of the notches 1.22 is two. One is arranged at the front end of the connecting part 1.2, and the other is arranged at the tail end of the connecting part 1.2. Setting the notches 1.22 at both ends of the connecting part 1.2 makes production and manufacturing more convenient;

[0036] After the limiting part 2.3 enters the notch 1.22, it supports and limits the connecting part 1.2 at both ends in the length direction, plays a role in vertically and horizontally supporting the tool body 1, further improves the firmness of the connection, and makes the stress performance of the tool body 1 better.

[0037] Another feature of this device is that injection molding can reduce production costs and improve production efficiency.

[0038] While ensuring functionality, the tool holder 2 and the tool body 1 can also be matched with different materials and colors to improve the aesthetic appearance of the product.

[0039] By optimizing the weight distribution of the tool body 1 and the handle 2.1, the weight balance of the tool can be improved, making it more stable and accurate during cutting.

[0040] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
