Abstract
Crankshafts for handheld power tools are provided. A crankshaft includes an input section configured to be coupled to a motive device and an output section comprising first and second engagement members. The first and second engagement members are configured to drive a first and second cutting implement, wherein the first and second engaging members are spaced apart from each other in a direction along a rotational axis of the crankshaft and in a direction transverse to the rotational axis of the crankshaft, and wherein the first and second cutting implements are each coupled to or detached from the crankshaft by translating relative to the crankshaft in a direction along the rotational axis.

A handheld power tool comprising:
- a first cutting implement;
- a second cutting implement;
- a motive device;
- and
- a crankshaft connecting the motive device to the first and second cutting implements, the crankshaft comprising:
- an input section coupled to the motive device;
- and
- an output section comprising:
- a first engaging member configured to drive the first cutting implement;
- and
- a second engaging member configured to drive the second cutting implement;
- wherein the first and second engaging members are spaced apart from each other in a direction along a rotational axis of the crankshaft and in a direction transverse to the rotational axis of the crankshaft, and
- wherein the first and second cutting implements are each configured to be detached from the crankshaft by translating relative to the crankshaft in a direction along the rotational axis.
