Abstract: A trigger structure for switching one shoot mode or repeat shoot mode includes a trigger member and a switching member. The trigger member has a recess defined laterally. Two protrusions are defined in the inner wall of the recess. The switching member has an adjusting member and a trigger plate. Under this arrangement, when the adjusting member is pressed into the recess, the trigger plate is at one position to allow the trigger to shoot in a repeat shoot mode; when the adjusting member is turned to abut against the two protrusions, the trigger plate is at another position to allow the trigger to shoot in a one shoot mode.

Abstract: The present invention provides a rechargeable electric tool in which a battery pack as a power supply slides in a battery holder formed in an end part of a housing. A bag-shaped waterproof cover covering the battery pack including a coupling part between the battery holder and the battery pack is formed by two divided covers which are separated to the front and rear sides in a slide attachment direction of the battery pack. Between the two divided covers, a coupling mechanism can be moved to a coupling position or a coupling cancelling position. The coupling position is a position in which the divided covers are coupled to each other in an attached state where the coupling part and the battery pack are covered. The coupling cancelling position is a position in which coupling of the divided covers is cancelled.
