Abstract: A foot repair device is provided, which includes a housing, a foot repair device main body, and a functional head. The housing forms a handle, and the handle includes a first handle end and a second handle end. The foot repair device main body is accommodated in the housing and includes a driving motor, a power supply component, and a control component. The functional head is detachably connected to the driving motor, and the control component includes a control circuit board, a switch button, and a speed control dial. The speed control dial adjusts a rotation speed of the functional head by adjusting an output rotation speed of the driving motor. The present disclosure provides a reasonable layout of switch button and speed control dial, allowing a user to easily control the switch and adjust the speed without significantly moving their fingers during operation.
