Abstract: An electrically powered garden tool includes an electric motor mounted upright within an outer shell housing, a pair of relatively reciprocating shear blades assembled to be driven by operation of the motor through a crank mechanism provided within a lower portion of the outer shell housing, and a cooling fan assembled to be driven by operation of the motor for introducing outside air into an upper portion of the outer shell housing to exhaust the introduced air from a lower portion of the outer shell housing. In the garden tool, a downward exhaust opening is formed within a lower end peripheral wall of the outer shell housing enclosing the crank mechanism such that the air spouted by rotation of the cooling fan blows out downward from the downward exhaust opening to restrain the occurrence of blowing noise of the air.

Abstract: An apparatus, method and system for cutting a material involves a cutting device with a body and a base. The body attaches to the base by a swing pivot that swings to position the body. A rotary blade, powered by an electric motor of the cutting device, is associated with the body. The body with the rotary blade may descend upon a table configured to receive the material. The table is mounted on the base beneath the rotary blade. An illumination device that emits light is coupled to a sliding, support portion beneath the swing pivot to direct light toward the rotary blade. Further, a light emitting diode (LED) may be mounted within the illumination device at an angle relative to the body to illuminate the material.

Abstract: An auxiliary handle (10) comprises a first clamp member (21), a second clamp member (31), an operation rod (40) and a grip (50). By rotation of the operation rod (40), the first clamp member (21) is moved toward a distal end of the operation rod (40), and at the same time, the second clamp member (31) is moved toward a base end of the operation rod (40). Accordingly, the first clamp member (21) and the second clamp member (31) are moved to be close to each other. As a result, an auxiliary handle attachable part (140) of a screw driver (100) is clamped by the first clamp member (21) and the second clamp member (31), and thereby the auxiliary handle (10) is attached to the screw driver (100).

Abstract: A power tool of one aspect for tightening a screw to a tightening-target-object is provided with a motor as a drive force. A motor controlling device controls the motor so as to make rotational frequency of the motor in accordance with an input operation received by an input-operation receiving unit. A first setting unit sets a maximum rotational frequency to a given first maximum rotational frequency when the motor is initiated. If the power tool clears a given condition for increasing rotational frequency after the motor is initiated, a second setting unit sets the maximum rotational frequency to a given second maximum rotational frequency that is larger than the first maximum rotational frequency.

Abstract: To provide a chain tension adjustment device for a chain saw. When a first mechanism is rotated around an axis, a bevel gear of a second mechanism is engaged with a bevel gear of the first mechanism and rotated, and a bevel gear of a third mechanism is engaged with the other bevel gear of the second mechanism, so that a shaft portion is rotated. A plate portion integrated with a nut portion of a fourth mechanism screwed on a screw formed on the shaft portion moves in an axial direction, and a guide bar engaged with an engagement portion of the plate portion via an engagement hole moves in a longitudinal direction, to adjust tension of the chain saw by adjusting the movement amount. Thus, fine adjustment can be performed while reducing an operating force, and reducing the weight and the cost.

Abstract: A power tool includes a spindle and a clamp shaft, and drives a tool accessory clamped by an outer flange and a clamp head. A ball or a grooved clamping element is configured to hold the clamp shaft against the spindle in a fixed manner. A holding element holds and moves the ball or grooved clamping element. A coil spring biases the holding element. The ball or grooved clamping element is movable between a first position where it holds the clamp shaft and a second position where it does not hold the clamp shaft. The holding element is capable of moving the ball or the grooved clamping element from the first position to the second position. The coil spring biases the holding element and prevents movement of the holding element when the ball or the grooved clamping element is located in the second position.
