1. A reciprocating saw comprising:
a housing formed with an accommodating space and a first gripping part for a user to grip, the housing also formed with a second gripping part extending in a direction of a second gripping part straight line, the second gripping part formed with a gripping groove transverse to the direction of the second gripping part straight line;
an electric motor disposed in the accommodating space and including a winding extending in a direction of a first straight line;
a first transmission wheel disposed in the accommodating space and connected to the electric motor;
an output shaft reciprocating in a front-rear direction under a driving action of the electric motor;
the first transmission wheel being fixed in the accommodating space by a support shaft extending in a direction of a second straight line, and rotatable about the second straight line under the driving action of the electric motor;
the electric motor including a first end and a second end in the direction of the first straight line, and a first plane perpendicular to the first straight line and passing through a first end face of the first end being defined; a second plane perpendicular to the first straight line and passing through a second end face of the second end being defined, the first plane being parallel to the second plane, and the winding being located between the first plane and the second plane;
the support shaft being at least partially located between the first plane and the second plane.
