Description

Electric tool conversion head Technical Field The utility model relates to the technical field of electric tools, in particular to a conversion head of an electric tool. Background The electric tool generally comprises an electric drill, an electric wrench, an electric screwdriver, an electric hammer and an impact electric drill, and according to different use scenes, different electric tools are often required to adapt to the scenes of drilling, impact screwing and the like. However, a single electric tool has the problem of single function, and multiple functions of one machine cannot be realized; Chinese patent publication No. CN216152272U discloses a locking device of a power tool conversion head and a power tool, the conversion head has a complex structure and cannot implement various conversions, so a power tool conversion head solution is needed. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides the electric tool conversion head which has compact structure, rapid mode switching and stable power output. In order to solve the technical problems, the utility model solves the technical problems by the following technical scheme that the electric tool conversion head comprises a shell, wherein an input shaft connected with an electric tool is arranged in the shell, the input shaft is connected with an output shaft, and a conversion unit for the output shaft is arranged in the shell; The conversion unit comprises a first fluted disc arranged in the shell and a second fluted disc connected to the output shaft, the second fluted disc is arranged on one side of the first fluted disc through a spring, and the output shaft is propped against the second fluted disc to overcome the spring and match with the first fluted disc. In the above scheme, preferably, the device comprises a speed reduction unit, wherein the speed reduction unit comprises an output gear and a plurality of rotatable speed reduction gears, the speed reduction gears are uniformly distributed on a mounting piece, and an annular gear is arranged on the outer side of the mounting piece.
