| description | The utility model discloses a variable-speed drill bit special for drilling. Comprising an output gear, a driven gear, a semicircular ball, a transmission shaft, a bevel gear, a spring, a shaft support, a sector gear, a shifting rod, a pressing rod, a motor gear A, a servo motor A, a short shaft A, a disc frame, a motor support, a servo motor B, a motor gear B, a speed change fluted disc, a short shaft B, an output shaft, a bearing, a lower end shell, a drill bit, drill teeth, an upper end shell and a middle end shell. When the variable-speed transmission is used, speed change can be carried out on the premise that the constant power of the output motor is kept, the speed change principle is achieved through a mechanical mechanism instead of changing the output power of the motor, and the purpose of changing the output speed of the variable-speed fluted disc is achieved through meshing with different gear rings of the variable-speed fluted disc under the same output power.
