    [0001] [0001] 1. Field of the Invention
    [9002] [9002] The invention relates to the technical field of electric tools, in particular to a multifunctional quick assembly mounting hole for swing tools.
    [0003] [0003] 2. Description of the Related Art
    [0004] [0004] With the rapid development of industrial technology today and continuous development of industrial technology, more and more various electric tools have penetrated into many fields, such as cutting, polishing, trimming, drilling and so on. These electric tools usually comprise a drive motor, a transmission device connected to the drive motor, and a tool head driven by the transmission device. Tool heads of different structures have different functions. The tool heads people used in the past did not have the function of quick assembly; it is very troublesome to replace tool heads with different functions, which not only wastes time and {ool materials, but also has extremely low labor productivity and is not easy to store. Common tool heads include straight saw blades, circular saw blades, triangular sanding discs, scrapers, etc, which can meet work requirements such as sawing, cutting, grinding, and scraping. Later, people designed the tool head into a detachable structure; by replacing the tool head, different functions were obtained, which not only greatly saved time and tool materials, but also facilitated storage, and it can also be carried when working out. At present, different factories use different specifications of the hole-type interface, which makes the matching tool variety. It is extremely inconvenient for users to purchase accessories, which not only wastes consumers’ time to purchase, but also makes it difficult to purchase accessories when using products from the same factory.SUMMARY OF THE INVENTION
    [9005] [9005] In order to solve the existing problems above, the invention provides a multifunctional quick assembly mounting hole for swing tools with high practicability, simple structure, convenient carrying, quick assembly, wide application range, which is suitable for multiple machine connection modes.
    [0006] [0006] The invention adopts the following technical solutions: multifunctional quick assembly mounting hole for swing tools, comprising an assembly bottom plate, a bending transition segment, and a tool head connecting plate, wherein the bending transition segment is arranged between the assembly bottom plate and the tool head connecting plate; the bending transition segment is arranged obliquely, and the bending transition segment is in arc transition between the assembly bottom plate and the tool head connecting plate; the assembly bottom plate is provided with a first assembly positioning boss and a second quick assembly positioning boss; the center of the second quick assembly positioning boss is provided with a quick assembly through hole; one side of the assembly botiom plate is provided with clearance openings that are in through connection to the quick assembly through hole; the assembly bottom plate is provided with limiting clearance through holes that penetrate the assembly bottom plate and are in through connection to the second quick assembly positioning boss and the quick assembly through hole; the limiting clearance through holes are symmetrically arranged on both sides of the second quick assembly positioning boss, and the clearance openings are symmetrically arranged on both sides of the second quick assembly positioning boss; the two sides of the quick assembly through hole are symmetrically provided with inside limiting holes that are in through connection to the quick assembly through hole; the upper wall of the second quick assembly positioning boss is provided outside positioning holes, and the outside positioning holes are arranged in a flower-shaped matrix array around the center of the quick assembly through hole; the first assembly positioning boss is arranged as a regular prismoid with openings at the lower end; the upper wall of the first assembly positioning boss is provided with a central hole penetrating up and down and flower-shaped holes that are in through connection to the central hole; the flower-shaped holes are circumferentially distributed at equal intervals along the edge of the central hole; the side wall of the first assembly positioning boss is provided with hollow arc-shaped bulges that are in through connection to the first assembly positioning boss.
