摘要： An impact tool includes a housing; and a motor, a tubular tool holder, a driving mechanism, a rotation shaft, a driving mechanism housing region inside the housing. The tool holder has a distal end on which a bit is mountable. The driving mechanism is configured to hammer the bit. The rotation shaft is disposed in the driving mechanism and rotates by a rotation of an output shaft of the motor. The driving mechanism housing region houses the driving mechanism in a sealed state inside the housing. The air escape path that releases air inside the driving mechanism housing region to outside of the driving mechanism housing region is formed inside the rotation shaft while an inlet of the air escape path is formed on an outer peripheral surface of the rotation shaft.

摘要： A hydraulic hammer includes a power cell. A work tool is partially received in, and movable with respect to, the power cell. A sleeve is positioned in the power cell that defines a centerline. A piston is concentrically positioned in the sleeve and movable in the sleeve between a first position in contact with the work tool and a second position out of contact with the work tool. A magnetic guide system includes at least one of a first magnetic guide component disposed in the piston and at least one of a second magnetic guide component disposed in the sleeve that interact to produce magnetic repellent forces therebetween to urge the radial position of the piston towards the center line.

摘要： A handheld power tool is disclosed. The tool has a housing, a hammer mechanism and a torque coupling. The hammer mechanism includes a beater which is movably guided along the working axis in the guide tube. The guide tube is mounted in a suspension attached to the housing so that it is movable along the working axis. The torque coupling is mounted on the guide tube and is supported on the suspension in the impact direction. The guide tube is supported on the torque coupling in the impact direction. The guide tube may be shifted with respect to the housing in the impact direction such that the torque coupling is shifted relative to the housing through the guide tube in a positively guided manner.
