Claims (1)

[Scope of utility model registration request] A motor, a gear mechanism for transmitting the rotation from the motor, a spindle for transmitting the rotation transmitted to the gear mechanism to the tip tool, a rotation ratchet fixed to the spindle, and a gear cover opposite the rotation ratchet. A fixed latch fixed inside and abutting against the rear end of the spindle via a steel ball, and supporting the steel ball to prevent reciprocating movement of the spindle due to engagement between the rotary latch and the fixed latch, or The power tool has a motion mode switching member that releases the support and provides reciprocating motion, and selectively engages both ratchets to reciprocate the spindle back and forth to apply impact force to the tip tool. An operating member made of an elastic body is provided at both ends of the mode switching member, the tip of the operating member projects from an opening provided in an outer frame member of the power tool, and either the operating member or the opening of the outer frame member A mode switching mechanism characterized in that a locking protrusion is provided on one side and a locking groove is provided on the other side to determine the position of the mode switching member.
