Abstract:
1. A power tool, comprising: a housing configured to accommodate at least an electric motor, a tool bit extending from a forward portion of the housing along an axial direction of the housing, a handgrip extending obliquely rearward from the housing with respect to the axial direction, and a trigger configured to actuate the electric motor and disposed on a forward portion of the handgrip adjacent to the tool bit, wherein at least first and second cross-sections of the handgrip taken in a direction parallel to the axial direction are each at least substantially oval, the first cross-section is disposed in a longitudinal intermediate region of the handgrip configured to be grasped by one of a middle finger and a ring finger while a forefinger is grasping the trigger, the second cross-section is disposed in a longitudinal distal region of the handgrip adjacent to a battery holder located on a terminal end of the handgrip, the second cross-section being configured to be grasped by a pinky finger while the forefinger is grasping the trigger, the first cross-section has a first cross-sectional area and the second cross-section has a second cross-sectional area, the first cross-sectional area being greater than the second cross-sectional area, a rearward end surface of the handgrip outwardly bulges in a rearward direction along a longitudinal direction extending from the housing to the terminal end of the handgrip, the longitudinal direction being at least substantially perpendicular to the axial direction, at least a forward end surface of the handgrip, which is opposite of the rearward end surface, is covered with a cushion material at least in the longitudinal direction between the first cross-section and the second cross-section, a first normal extends obliquely upward from the rearward end surface of the longitudinal distal region of the handgrip towards the axial direction of the housing, a second normal extends obliquely upward from a surface of the trigger towards the axial direction of the housing and the first normal extends in parallel with the second normal, a rearmost edge of the housing in the axial direction is disposed farther rearward than a rearmost edge of the battery holder in the axial direction, and the battery holder is configured to receive and engage a battery pack.
