摘要： An electric boring tool(1) comprises an electric motor (40), a switch trigger(61), a tip tool (20) driven by driving force of the electric motor(40), a power transmission mechanism (14) for transmitting the driving force of the electric motor (40) to the tip tool (20) as rotational force and/or hammer force, and a motor control unit (50, 55) for controlling speed of the electric motor (40) in response to an extent of pulling of the switch trigger (61). The motor control unit (50, 55) subjects the electric motor (40) to low speed control (109, 126) after the electric motor (40) is started up, and controls the speed of the electric motor (40) in response to the extent of pulling of the switch trigger (61)when the load current (107) of the electric motor is set value or greater during the low speed control (109).

摘要： A stake driver for driving wood stakes into a soil has a rectangular hollow housing having an open top and an open bottom. The bottom portion is configured for receiving at least a part of the wood stake therein, while an elongated driving shaft extends from an interior of the housing upwardly above a top edge of the housing. The upper part of the driving shaft is configured for engagement by a power transmitting tool, such as a jack hammer. A driving pad is secured to a bottom end of the driving shaft transversely to the longitudinal axis of the housing. At least one hammer plate is secured, through Connection to a shaft sleeve, to the driving shaft above the driving pad. The hammer plate and the driving pad are each configured to move in an axial direction inside the housing and transmit a hammering force to the wood stake.
