The invention relates to a multifunctional tool head installation hole which comprises an installation circular hole, wherein a groove shape on the periphery of the installation circular hole is equally divided into 12 parts, the groove shape is arranged in a shape like a plum blossom, and peripheries of quincunx holes are provided with small semi-circle rectangular holes of 12 equal parts. The multifunctional tool head installation hole is applied to installation tool heads on electric power tools, the edge of the installation hole is provided with the 12 quincunx holes distributed uniformly, the quincunx holes are provided with the small semi-circle rectangular holes of 12 equal parts to facilitate installation and using of more than 98% of multifunctional electric power tools, therefore the utilization rate of the electric power tools is greatly improved, and due to the fact that replacement of tool heads is convenient and fast, labor productivity is also improved.
Description
technical field [0001] The invention relates to an electric tool accessory, in particular to a multifunctional tool head installation hole. Background technique [0002] Today, with the rapid development of industrial technology, there are more and more various electric tools, and people's awareness of electric tools has been greatly improved, such as cutting, grinding, trimming, engraving and so on. These electric tools usually include a driving motor and a transmission device and a tool head driven by the transmission device. Tool heads with different structures have different functions, such as: engraving requires a tool head with engraving, cutting requires a serrated saw blade tool head, etc. . In the past, the power tools for each function were equipped with a set of tool heads, which was a big waste of resources and was not convenient for storage. Later, people designed the tool head as a detachable structure. By changing the tool head, different functions can be ob...
