  • Publication number: 20230284556
    Abstract: A working machine may include: a first blade; a second blade overlapping with the first blade in an up-down direction; and a holding unit configured to hold the first blade and the second blade overlapping each other in the up-down direction. The first blade may be configured to reciprocate in a direction perpendicular to the up-down direction with respect to the second blade. The first blade may include a first elongated hole having a longitudinal direction along the reciprocating direction. The second blade may include a second elongated hole having a longitudinal direction along the reciprocating direction. The holding unit may include: a holding part inserted in the first elongated hole of the first blade and the second elongated hole of the second blade; and an outer sleeve having a cylindrical shape and supported by the holding part such that the outer sleeve is rotatable around the holding part.

  • Patent number: 9044848
    Abstract: An impact tool includes a motor, a rotating shaft rotationally driven by the motor, a swinging member that swings in an axial direction of a tool bit by rotation of the rotating shaft, a tool driving mechanism connected to an end region of the swinging member in a direction transverse to the axis of the rotating shaft. The tool driving mechanism is moved rectilinearly in the axial direction of the tool bit by swinging movement of the swinging member thereby rectilinearly driving the tool bit. A vibration reducing member reduces vibration caused in the axial direction of the tool bit during operation of the tool bit. The vibration reducing member is disposed on an opposite side of a rectilinear working axis of the tool bit from the rotating shaft and connected to a connecting part between the swinging member and the tool driving mechanism so as to be driven.
