Provided is a handheld power tool, including: an output shaft that defines an output axis; and an output housing that defines a first central axis passing through a geometric center, where a radial distance from the first central axis to an outer edge of the output housing is R; the output shaft includes a first position and a second position; when the output shaft is at the first position, a radial distance from the output axis to the first central axis is D1; and when the output shaft is at the second position, the radial distance from the output axis to the first central axis is D2, D1 being less than D2, D1 being greater than or equal to 0 and less than R, and D2 being greater than 0 and less than or equal to R.
