摘要： A torque output tool includes a housing; an electric motor disposed in the housing; an output shaft capable of being connected to a working accessory and driving the working accessory to rotate; and a transmission assembly. The transmission assembly includes a drive wheel drivable by the electric motor to drive the output shaft to rotate about a first axis; a shaft lock ring disposed around the output shaft; and multiple locking posts disposed in the shaft lock ring and around the output shaft. The torque output tool further includes a spacer disposed between the drive wheel and the shaft lock ring and used for separating the locking posts from at least part of the drive wheel.

摘要： An impact drill includes an output shaft capable of rotating around a first axis and moving along the first axis, a housing, a first impact block fixedly connected to the output shaft, a second impact block, a stopping element for stopping the output shaft from moving backward, and a movable element mounted on the housing. The housing is formed with a through hole for accommodating the movable element. The through hole passes through the housing in a first line and the movable element is capable of moving to a first position and a second position along the first line. When the movable element moves to the first position, the movable element prevents the output shaft from moving backward. When the movable element moves to the second position, the movable element allows the output shaft to move backward.

摘要： A power tool, including an output member, a motor, a housing, a transmission device, and a shifting device. The shifting device includes a first shifting element, a second shifting element, an operation member, and a connecting member. The first shifting element is capable of switching between a first position and a second position, and the second shifting element is capable of switching between a third position and a fourth position. When sliding relative to the housing, the operation member drives the first shifting element to switch between the first position and the second position, and a position of the second shifting element remains unchanged. When the operation member rotates relative to the housing, the connecting member drives the second shifting element to switch between the third position and the fourth position, and a position of the first shifting element remains unchanged.

摘要： An impact drill includes a lock pin, a biasing element, a function conversion member and an operation member. The lock pin is connected to the locking ring. The biasing element is connected to the lock pin and provides a biasing force that causes the lock pin to press against the locking ring. The function conversion member includes a stop portion configured to stop the movement of the lock pin along the first axis and a release portion configured to allow the movement of the lock pin along the first axis. The operation member is connected to the function conversion member. The operation member is configured to drive the function conversion member to rotate around the first axis to switch the stop state of the movement of the lock pin along the first axis.

摘要： An angle drill includes a housing; an electric motor at least partially disposed in the housing and including a motor shaft rotating about a motor axis; an energy source supplying power to the electric motor and detachably connected to the housing; and an output mechanism including an output shaft rotating about a first axis, where the output shaft is driven by the electric motor, and the first axis intersects with the motor axis. When the torque of the output shaft is greater than or equal to 10 N·m, the ratio of the output power of the angle drill to the weight of the angle drill is greater than or equal to 220 W/kg.

摘要： A battery pack includes a casing, a cell group, a bracket, cell connection pieces, and output terminals. A plane where the output terminals of the battery pack are located is defined as an upper plane, a plane where the output terminals of the cell group are located is defined as a front plane, and a plane perpendicular to the upper plane and the front plane is defined as a side plane. One of the cell connection pieces includes a bracket-fixed surface, a cell connection surface, and a power supply output surface. The bracket-fixed surface is fixed on the bracket and parallel to the side plane. The cell connection surface is connected to the power supply output terminals of the cell group and parallel to the front plane. The power supply output surface is connected to the output terminals and parallel to the upper plane.
