A latch mechanism for a power tool such as a hedge trimmer having a housing accommodating a motor and a handle assembly adapted to pivot relative to the housing between a plurality of positions is disclosed. The latch mechanism includes a lever ( 210 ) carrying a first retaining member ( 181 ) for movement relative to the housing between an engaging condition to engage the handle assembly to releasably retain the housing relative to the handle assembly, and a retracted condition for allowing pivotal movement of the housing relative to the handle assembly. A second retaining member ( 182 ) is movable relative to the housing ( 103 ) between an engaging position to engage the handle assembly to releasably retain the housing ( 103 ) in position relative to the handle assembly, and a retracted condition for allowing pivotal movement of the housing relative to the handle assembly. The retaining members ( 181 ), ( 182 ) are biased towards their engaging conditions by means of a spring ( 186 ). An interlock member ( 214 ) on lever ( 210 ) cooperates with an arm member ( 163 ) to prevent disengagement of the first ( 181 ) and second ( 182 ) retaining members from the handle assembly when the motor is actuated, and for preventing actuation of the motor when the first ( 181 ) or second ( 182 ) retaining member is in a retracted condition.
