Abstract: A blower, comprises a blower body, accommodating therein a fan and an electric motor driving the fan to rotate. A rotation shaft of the fan defines a longitudinal axis. A blow pipe is removably attached to the blower body. A tapered member is provided between the electric motor and an air inlet of the blower body, the tapered member gradually narrowing toward the air inlet.

Abstract: The present invention provides a working device, comprising a working portion and a grip portion. The working portion comprises a driving component and a working component driven by the driving component. The driving component comprises an electric motor and an electric motor housing. The electric motor housing comprises a housing body and a connecting portion located on a rear side of the housing body. At least one air intake hole is formed in the connecting portion, and is in communication with an inner cavity of the housing body. In the working device of the present invention, the driving component is provided with an air intake hole to allow air for cooling an electric motor to enter the interior of the driving component.

Abstract: A utility knife includes a handle having a body and a receiving aperture. The utility knife further includes a collet at least partially receivable in the receiving aperture, and a sleeve that is engageable with and that surrounds the collet. The collet is configured to alternately receive one of a portion of a blade of a first type in a first slot and a portion of a blade of a second type in a second slot. The collet and the sleeve are co-rotatable relative the handle to move the collet to a secured position in which one of the blade of the first type and the blade of the second type are secured to the collet.

Abstract: A rotary tool includes a housing, a drive shaft positioned within the housing, and a bit holder. The bit holder is positioned adjacent a distal end of the housing and is driven by rotation of the drive shaft. The rotary tool also includes a wrench assembly for adjusting the bit holder and a light source configured to emit light in a direction toward the bit holder. The wrench assembly is positioned adjacent the bit holder and is movable between a first position and a second position. The wrench assembly is coupled to the housing and disengaged from the bit holder assembly in the first position and is engaged with the bit holder assembly in the second position.

Abstract: The power tool comprises a first power tool portion having a rotatable collar and a first locking member arranged to be actuated by the rotatable collar and a second power tool portion having a second locking member. The rotatable collar is rotatable about an axis for actuating the first locking member to removably engage the first locking member with the second locking member, thereby releasably locking the first power tool portion with the second power tool portion along the axis.

Abstract: A rotary tool assembly includes a rotary tool having a body with a working end and a rear end, a motor disposed within the body, and a drive shaft rotatably driven by the motor. A base of the rotary tool assembly includes a battery receptacle configured to receive a battery pack and a stand for supporting the rotary tool when the rotary tool is not in use. The stand includes two arms defining a tool receptacle therebetween in which the rotary tool is supported. A power cord extends between the base and the rotary tool to transfer electric power from the base to the rotary tool to selectively power the motor. The battery pack is received in the battery receptacle for form a foot of the base.

Abstract: An electric handcart, comprising: a main body (1), a power supply device (9) mounted on the main body (1), a power device, and a control device. The power supply device (9) and the control device are separately connected to the power device.

Abstract: A tripod light includes a frame supporting a light assembly, and a support assembly coupled to the frame and configured to support the frame on a surface. The support assembly includes a first leg, a second leg, and a third leg. The support assembly is pivotable relative to the frame about a first axis between a stowed position in which the support assembly including the first leg, the second leg and the third leg is adjacent the frame, and a deployed position in which the support assembly including the first leg, the second leg, and the third leg extends away from the frame. Each of the second leg and the third leg is configured to rotate relative to the first leg about a second axis between a collapsed position and a respective extended position of the second leg and the third leg.
