Abstract
A compound saw, including a frame; a motor driving assembly, which is sleeved in the frame and rotatable around a first axis perpendicular to a main plane of the frame relative to the frame; and a saw blade, which is mounted on an output shaft of the motor driving assembly and rotatable around a second axis passing through the output shaft relative to the motor driving assembly. The second axis is parallel to the first axis, and there is an eccentric distance between the second axis and the first axis.
Claims7
A compound saw, comprising:
- a frame;
- a motor driving assembly sleeved in the frame and rotatable around a first axis perpendicular to a main plane of the frame relative to the frame;
- a saw blade mounted on an output shaft of the motor driving assembly and rotatable around a second axis passing through the output shaft relative to the motor driving assembly, and
- a lower shielding case hinged on the frame and swingable within the main plane of the frame relative to the frame,
- wherein the second axis is parallel to the first axis, and there is an eccentric distance between the second axis and the first axis,
- wherein the frame is provided with a cylindrical mounting hole, the motor driving assembly is provided with a cylindrical surface, the cylindrical surface of the motor driving assembly is fittingly sleeved in the cylindrical mounting hole of the frame, and the first axis is a common central axis of the mounting hole and the cylindrical surface, and
- wherein the motor driving assembly is capable of driving the lower shielding case to swing when the motor driving assembly is rotated around the first axis relative to the frame.
