Description

Technical Field

[0001] The utility model relates to the technical field of broaches, in particular to an assembled broach. Background Art

[0002] A modular broach is a tool that is assembled from multiple components and can be disassembled and reassembled as needed. The main components of this tool include the blade, handle and connecting rod.

[0003] The blade is the key component of the assembled broach, which is usually made of high-strength materials, such as carbide, high-speed steel, etc. The blade shape can be designed according to different processing requirements, such as straight blade, curved blade, etc. The handle is the handle part of the assembled broach, which is usually made of durable materials, such as metal or plastic. The design of the handle should conform to the principles of ergonomics and provide a stable grip and a comfortable feel. The connecting rod is the component that connects the blade and the handle together. It is usually made of metal material with sufficient strength and stability.

[0004] When using an assembled broach, you can select the appropriate blade and handle for assembly as needed. For example, when fine processing is required, you can choose a slender blade and a handle that feels comfortable; when rough processing is required, you can choose a wide and thick blade and a durable handle. The advantage of an assembled broach is that the blade and handle can be replaced as needed, which extends the service life of the tool. At the same time, it can also be freely assembled according to different processing requirements, improving processing efficiency. Existing assembled broaches are usually fixed by screws. When there is no corresponding screwdriver at hand, the broach cannot be replaced, which affects subsequent processing. To address this problem, we have proposed an assembled broach.
