Leaf blower-duct system improved wheel structure

The present invention discloses a leaf blower-duct system improved structure of the wheel, the wheel comprising a duct and a duct system provided in the head end of the outer wall of the duct, the duct system comprises a duct wheel head end along the outer wall of the duct axis and extending the track rail disposed on a wheel carrier, the wheel frame is mounted on wheels, with a gear provided on the track structure, the gear wheel carrier is provided with adjustment means. The present invention is provided in the duct system allows the wheels to adjust the degree of freedom having two wheel track directions duct and the axial position of the wheel at a predetermined position of the fixed gear structure, so mounted wheel carrier wheels can be moved adjusting the position of the track by a fixed structure to achieve a gear position, therefore, the duct is very convenient adjustment of the position of the wheels.
