The invention provides a handheld electrical power tool (100). The handheld electrical power tool (100) comprises a working device (10) for performing a working function of the handheld electrical power tool (100), a power device (50) including a motor (51) for driving the working device (10), a power supplying unit (20) for supplying power to the power device (50), and an operating device (40) through which a user can operate. The operating device (40) comprises an operating handle (411) and a speed regulating device (42) which is arranged beside the operating handle (411). The speed regulating device (42) comprises a speed regulating switch (422) and a speed regulating operating member (423) which is connected to the speed regulating switch (422) and drives the speed regulating switch (422) to act. When the rotating speed of the motor (51) increases from zero to the maximum, the rotating angle of the speed regulating operating member (423) is 0-360°. The handhold electric tool has the advantages that a stepless speed change of the motor (51) is achieved and the operation is convenient.
