摘要： A handle for a tool includes a handle body, an operation device and a pair of clamp halves. The operation device has an operation member operable by an operator. At least one of the clamp halves can move relative to the handle body along an axis. As the operation member is operated, the one of the handle halves moves along the axis, so that the distance between the handle halves can be changed for clamping or releasing a portion of the tool.

摘要： A working tool in which a tip tool with a longitudinal shaft is linearly moved, wherein a motor and other tool constituting members are effectively cooled. In order to cool the inside of a motor-driven hammer comprising a main body, a motor, and a motion converter, the hammer is provided with a first cooling air passage through which a cooling air is supplied to the motor, and a second cooling air passage through which a cooling air is supplied to a hammer portion. To generate a cooling air to be supplied to the first and second cooling air passages, a cooling fan is provided at a lower portion of an output shaft of the motor and a hammer portion cooling fan is provided between the output shaft of the motor and the motion converter.

摘要： Mode switching is reliably performed with a durable and small-sized configuration. A clutch pin (40) is provided in a reduction shaft (34) and configured to be slidable by an operation from outside, and a driven gear (38) is inserted onto the reduction shaft (34) and configured to be rotatable separately from the reduction shaft (34), so that a clutch mechanism is provided. By switching the clutch mechanism, a selection can be made between a hammer drill mode and a hammer mode. Meanwhile, the clutch pin (40) is configured to be slidable to a sliding position where the clutch pin (40) runs through the reduction shaft (34) so as to be capable of protruding upward beyond the reduction shaft (34), and at the sliding position, the clutch pin (40) engages with an engagement hole (46) provided on the tool holder (7) side so that a rotation of the tool holder (7) can be locked, whereby in the hammer mode, a selection can be further made between a neutral state where the clutch pin (40) does not engage with the engagement hole (46) and a rotation locked state where the clutch pin (40) engages with the engagement hole (46).
摘要翻译：通过耐用和小型化配置可靠地执行模式切换。离合器销（40）设置在减速轴（34）中并构造成可以通过外部的操作而滑动，并且从动齿轮（38）插入到减速轴（34）上，并且构造成能够与减速轴（34），从而设置离合器机构。通过切换离合器机构，可以在锤击模式和锤击模式之间进行选择。同时，离合器销40能够滑动到离合器销（40）穿过减速轴（34）的滑动位置，以能够向上突出到减速轴（34）的上方，并且在所述滑动位置，所述离合器销（40）与设置在所述工具架（7）侧的接合孔（46）接合，使得所述工具架（7）的旋转能够被锁定，由此在所述锤模式中，可以进一步在离合器销（40）不与接合孔（46）接合的中立状态和离合器销（40）与接合孔（46）接合的旋转锁定状态之间进行。

摘要： A hammer drill has an aluminum cylinder non-rotatably mounted in a crank housing, a synthetic resin slide sleeve, and a tool holder. The latter two members are coaxially fitted over the front part of the cylinder. The slide sleeve is a cylindrical member slidably mounted between a large bore portion of the tool holder and the cylinder. A steel ring is mounted at the rear of the slide sleeve. The slide sleeve and the steel ring are urged in the forward direction by a compression spring interposed between a bevel gear and the steel ring. A first air chamber which is formed in the cylinder includes a plurality of air ports which are covered by the steel ring when the slide sleeve and steel ring are pushed in their respective rear positions by pressing a tool bit attached to the hammer against a work piece. A plurality of wide and narrow slits are formed in the front portion of the slide sleeve while a plurality of air passage holes are also formed in the large bore portion of the tool holder.
