This structure has certain shortcomings. Due to the objective existence of processing tolerances and assembly tolerances, after the motor bracket is fixed, its axis will be offset from the axis of the outer casing. When the fascia gun is operating, it will produce greater vibrations, and the user experience will be poor. Utility Model Content
