摘要： A power tool includes a tool head, a frame that rotationally couples with the tool head, a piston, and a motor that is operable to drive the piston to perform an operation on a workpiece. The power tool also includes a sensor that senses movement of the piston to provide sensor information indicative of the movement of the piston. The power tool further includes a controller that receives the sensor information from the sensor. The controller operates the motor to perform work on the workpiece until the sensor determines the piston has moved a target distance.

摘要： An example tool includes a housing; an inclined handle coupled to, and extending obliquely from, a top portion of the housing, where the inclined handle has a first trigger button and a second trigger button; and an interlocking mechanism disposed in the inclined handle. The interlocking mechanism is configured to disable one of the first trigger button or the second trigger button while the other of the first trigger button or the second trigger button is triggered.

摘要： A hydraulic tool includes a tool head and a moveable piston coupled to the tool head. The hydraulic tool head includes a plurality of jaws, which are operable to open and close for performing work on a workpiece. The hydraulic tool also includes a motor operable to drive the moveable piston to close the plurality of jaws to a closed position at which the work on the workpiece is completed. The hydraulic tool further includes a position sensor configured to detect when the plurality of jaws are at the closed position and responsively generate a sensor signal indicating that the plurality of jaws are at the closed position. Additionally, the hydraulic tool includes a controller configured to receive the sensor signal from the position sensor. The controller is configured to operate the motor based on the sensor signal that the controller receives from the position sensor.
