Hand tool adapter capable of increasing output torque or rotational speed
Abstract:
A hand tool adapter capable of increasing output torque or rotational speed has a main body. The main body has a through hole. The through hole is provided with a first rotary seat and a second rotary seat. The through hole of the main body is provided with an annular toothed portion. The first rotary seat is provided with a plurality of gears to mesh with the annular toothed portion. The second rotary seat is provided with a gear axle to mesh with the gears. By the speed-changing principle of the planetary gear, the first rotary seat is selected as the input axle to increase the output rotational speed of the second rotary seat, or the second rotary seat is selected as the input axle to increase the output torque of the first rotary seat.
