Abstract
The utility model relates to a multifunctional tool head installing hole, comprising an installing circular hole, the groove shape at the periphery of the installing circular hole is uniformly divided into 12 equal parts, each part of the groove shape is in the shape of a circular arc, the periphery of the circular arc holes is provided with small semicircular rectangular holes in 12 equal parts. The multifunctional tool head installing hole is suitable for installation of tool heads on an electric tool, the edge of the installing hole is provided with 12 circular arc holes in uniform distribution, and the small semicircular rectangular holes in 12 equal parts are in an outwardly-extended direction of the circular arc holes, facilitating installation and use of more than 98% of multifunctional electric tools, thereby greatly improving utilization rate of electric tools, and since replacement of the tool heads is convenient and fast, labor productivity is also improved.
Description
Technical field
The utility model relates to a kind of electric tool accessory, relates in particular to a kind of multifunctional tool head installing hole.
Background technology
In today of industrial technology develop rapidly, various electric tools are more and more, and people improve greatly to the cognition degree of electric tool, for example: cutting, polishing, pruning, engraving etc.These electric tools generally include drive motors and transmission device and by the tool heads of actuator drives, the tool heads of different structure has different use functions, as: engraving needs the carved tool heads of tool, and cutting needs jagged saw blade tool heads etc.The electric tool of every kind of function all was complete configuration tool head in the past, and was large to the wasting of resources, and was not easy to deposit.People were designed to dismountable structure with tool heads afterwards, by changing tool heads, obtained different functions, had not only saved greatly material, were convenient for carrying when going out to operate.Since also there is not the installation code of real tool heads at present, each manufacturer, according to production capacity, the process condition of oneself, the drive mechanism of designed, designed electric tool and the mounting structure of tool heads, the structure of each producer and each producer is all different.
Summary of the invention
The utility model provides a kind of simple in structure, applied widely, multifunctional tool head installing hole that versatility is good in order to overcome the above problems.
The technical solution of the utility model is: the multifunctional tool head installing hole, comprise the installation circular hole, and the flute profile of described installation circular hole periphery is divided into 12 equal portions, and flute profile is arranged to circular-arc, the outer small semicircle slot that is arranged with 12 equal portions in circular-arc hole.
The inward flange in described circular-arc hole is knuckle.
The inward flange of described small semicircle slot is knuckle.
Described circular-arc hole is consistent with the orientation angle of small semicircle slot equal portions.
The utility model is applicable in the erecting tools head on the electric tool, the installing hole edge has 12 circular-arc holes of even branch, circular-arc hole is outward extended with the multi-functional electric tools that the rectangle installing hole of the small semicircle of 12 equal portions is convenient to more than 98% and installs and uses, thereby improved greatly the utilization rate of electric tool, because it is convenient and swift to change tool heads, has also improved labor productivity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is that circular hole, the 2nd, circular-arc hole, the 3rd, small semicircle slot, the 4th, knuckle are installed among the figure.
The specific embodiment
The multifunctional tool head installing hole, comprise circular hole 1 is installed, the flute profile of described installation circular hole 1 periphery is divided into 12 equal portions, flute profile is arranged to circular-arc, the outer small semicircle slot 3 that is arranged with 12 equal portions in circular-arc hole 2, the inward flange in described circular-arc hole 2 is knuckle 4, and the inward flange of described small semicircle slot 3 is knuckle 4, and described circular-arc hole 2 is consistent with the orientation angle of small semicircle slot 3 equal portions.
