1. A working machine comprising:
a body;
a working part disposed on the body;
a prime mover;
a handle attached to the body and configured to be gripped by a user;
a switch mechanism for driving the prime mover;
a trigger member configured to be operated by the user for driving the prime mover and configured to be movable between a first position and a second position, wherein the first position is a position where the trigger member does not contact the switch mechanism and the second position is a position where the trigger member pushes in the switch mechanism; and
a lock member,
wherein
the handle is configured to shift between a working state and a non-working state,
the lock member is configured to:
move between a non-restriction position and a restriction position, wherein when the lock member is positioned at the non-restriction position, a user's operation on the trigger member from the first position to the second position is not restricted, and when the lock member is positioned at the restriction position, the user's operation on the trigger member from the first position to the second position is restricted;
be positioned at the non-restriction position when the handle is in the working state;
be positioned at the restriction position when the handle is in the non-working state; and
move from the non-restriction position to the restriction position in response to shift of the handle from the working state to the non-working state.
