摘要： A hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.

摘要： A brushless DC motor includes a stator, a rotor, and motor terminals mounted on the stator. Each motor terminal includes a planar portion extending circumferentially from the end insulator, a wire-receiving member extending from a first end of the planar portion and folded over an outer surface of the planar portion away from the center axis of the stator at an angle of less than 90 degrees, and a tab portion extending from a second end of the planar portion parallel to the center axis of the stator. A circuit board is disposed adjacent the motor including power switches mounted thereon for energizing the stator windings. Slots are formed in the circuit board to align with and securely receive the tab portions of the motor terminals, thus electrically connecting the motor terminals to the power switches.

摘要： A gripping device includes a housing has an annular flange and a plurality of positioning recesses provided at the annular flange, a rear handle assembled with the annular flange of the housing, a push button pivoted to the rear handle and partially exposed to the outsides, a positioning block disposed in the rear handle, and a link rod having two ends pivoted to the push button and the positioning block, respectively. When the push button is unlocked, the positioning block is driven by the link rod to be disengaged from the positioning recesses, such that the rear handle is rotatable to adjust angle. When the push button is locked, the positioning block is engaged with one of the positioning recesses under the force of an elastic member for positioning the rear handle.
Therefore, a user can operate the gripping device at an ergonomic angle.

摘要： A portable power tool, in particular an angle grinder, includes a housing that accommodates a drive and an electronic device with an interface configured to electrically connect the electronic device. The power tool further includes a housing inner part that is configured as a drive housing and supports the electronic device. The interface has at least one first electrical interface contact region and at least one second interface contact region spaced apart from the first interface contact region. At least one insulating element spaced apart from the interface contact regions is arranged between the housing inner part and the electronic device. The insulating element is configured to avoid an electrical short-circuiting connection between the first interface contact region and the second interface contact region.

摘要： An electric tool includes a motor, a first intermediate member configured to be displaced when a first accessory is attached to a first attachment portion, a second intermediate member configured to be displaced when a second accessory is attached to a second attachment portion, and a first interlock member. The first interlock member mechanically moves in conjunction with the respective displacements of the first intermediate member and the second intermediate member. The first interlock member is displaced in the same direction between when the first accessory is attached and when the second accessory is attached, and is cumulatively displaced when the first accessory and the second accessory are attached. The electric tool is configured in such a manner that power supply to the motor is permitted only in a state that the first interlock member is cumulatively displaced.

摘要： An impact power tool includes a transmission output shaft, a rotary impact assembly with a cam shaft, hammer, and anvil, and a tool output shaft rotatable with the anvil. A coupler removably couples the cam shaft to the transmission output shaft. When torque on the tool output shaft is less than or equal to a first threshold, the transmission output shaft, cam shaft, hammer, and anvil rotate together to transmit torque to the tool output shaft. When torque on the tool output shaft is above the first threshold, the hammer moves along the cam shaft away from the anvil by a first distance and applies rotary impacts to the anvil. When the hammer moves along the cam shaft away from the anvil by a second distance greater than the first distance, the coupler decouples the transmission output shaft from the cam shaft, interrupting torque transmission to the tool output shaft.

The structures disposed at the power head (120) and the structures disposed at the housing of the tool attachment (106, 108, 110) for defining the physical mating assembly are configured to contact each other before the structures disposed at the power head (120) and the structures disposed at the housing of the tool attachment (106, 108, 110) for defining the drive power transfer assembly contact each other responsive to operably coupling of the power head mating interface (121) to the tool mating interface (123). The structures disposed at the power head (120) and the structures disposed at the housing of the tool attachment (106, 108, 110) for defining the drive power transfer assembly are configured to contact each other before the structures disposed at the power head (120) and the structures disposed at the housing of the tool attachment (106, 108, 110) for defining the electronic assembly contact each other responsive to operably coupling of the power head mating interface (121) to the tool mating interface (123).
