Low-profile impact tools

1. An impact tool comprising:

a motor including an output shaft configured to rotate about a first axis; and

a drive train driven by the output shaft of the motor and to drive rotation of an output drive about a second axis that is non-parallel to the first axis;

wherein the drive train includes an impact mechanism comprising a hammer that rotates about a third axis to periodically deliver an impact load to an anvil, the third axis being parallel to and spaced apart from the second axis;

wherein the output drive comprises a ratcheting mechanism;

wherein the anvil comprises a first strut having a first end and a second end opposite the first end, the first end being configured to be impacted by the hammer when the hammer rotates about the third axis in a first rotational direction and the second end being coupled to the ratcheting mechanism, such that the first strut causes rotation of the output drive about the second axis in the first rotational direction when the first strut is impacted by the hammer; and

wherein the anvil further comprises a second strut having a first end and a second end opposite the first end, the first end being configured to be impacted by the hammer when the hammer rotates about the third axis in a second rotational direction and the second end being coupled to the ratcheting mechanism, such that the second strut causes rotation of the output drive about the second axis in the second rotational direction when the second strut is impacted by the hammer.

2. The impact tool of claim 1 , wherein the impact mechanism includes a spring that biases the hammer axially along the third axis toward the anvil.

3. The impact tool of claim 1 , wherein no portion of the hammer or the anvil intersects the second axis.
