  • Patent number: 9263715
    Abstract: A battery pack includes a casing having an opening, an engaging member having a stopper, and a regulating member configured to regulate a movement of the engaging member. The engaging member is supported in a slidable and rotatable manner relative to the casing, and is applied with a biasing force such that the stopper projects from the opening. The regulating member includes a contact portion configured to block a rotation of the engaging member and an operating portion configured to displace the contact portion to release a blocking of the rotation of the engaging member. When the operating portion is a non-operated state, the engaging member is slidable against the biasing force to retract the stopper. When the operating portion is in an operated state, the engaging member is rotatable against the biasing force to retract the stopper.

  • Patent number: 8272452
    Abstract: A hammering tool includes, within its tool main body, a piston which reciprocates by using a motor as its drive force, a hammering member which carries out its hammering operation in linking with the reciprocating motion of the piston, and an intermediate member which transmits a hammering force of the hammering member to a top end tool mounted on the top end of the tool main body. The tool main body further includes a measuring device which measures a hammering state of the hammering member and a control device which controls the number of rotations of the motor. The control device, according to measurement results of the measuring device, determines the limit number of times of hammering where the hammering member becomes unable to follow the reciprocating motion of the piston, and thus controls the number of rotations of the motor.
