Abstract
The utility model discloses a stepless speed regulator of an AC electric hand drill. The stepless speed regulator of an AC electric hand drill comprises a push type switch and a slide resistor. One end of the push type switch is connected with one pole of a power supply, and the other end of the push type switch is divided into two branches; one branch is connected with the T2 terminal of a silicon controlled rectifier, and the other branch is connected with one end of the slide resistor; the other end of the slide resistor is in series with one end of a divider resistor; a trigger is arranged between the other end of the divider resistor and the G terminal of the silicon controlled rectifier; the input terminal of a capacitor is connected with the other end of the divider resistor; the output terminal of the capacitor is connected with the T1 terminal of the silicon controlled rectifier and then is connected with the electric hand drill; and the electric hand drill is connected with the other pole of the power supply. According to the utility model, stepless speed control is achieved, when the AC electric hand drill begins to drill, the switch is slightly pushed, the rotating speed is low, a drilling position is easy to control, a drill bit is not easy to break, with the deepening of the drilling, the push force applying on the switch becomes larger and larger, the rotating speed becomes higher and higher, and the work efficiency is greatly raised.
