Adjustable duct mechanism for heating equipment

Outdoor power equipment, comprising:

• an air inlet;
• an air outlet;
• a fan configured to draw air through the air inlet and expel the air through the air outlet;
• a heating device configured to heat the air between the air inlet and the air outlet;
• and
• an adjustable duct connector fixedly coupled to at least one of the air inlet and the air outlet, the adjustable duct connector comprising:
• a base plate including a center portion and a plurality of plate arms extending radially outwardly from the center portion;
• a plurality of ring arms, each being movably coupled to a respective one of the plurality of plate arms;
• and
• a handle rotatably coupled to the center portion and each of the plurality of ring arms, so that each of the plurality of ring arms translates along the respective one of the plate arms, in response to selective rotation of the handle, between a first position where an outer periphery of the plurality of ring arms defines a first diameter and a second position where the outer periphery of the plurality of ring arms defines a second diameter, wherein the second diameter is greater than the first diameter.
