Abstract: The present invention relates to the technical field of outdoor equipment, in particular to an easily extendable and retractable canopy mechanism comprising two center hubs arranged up and down and several carrier rods. The first and second center hubs are arranged on the same vertical line. One end of the carrier rods is rotatably connected to the first center hub with equal angle between any two adjacent carrier rods. It also comprises equal number of support rods and carrier rods. One end of the support rods is rotatably connected to the second center hub and the other end is fixed on the side of the carrier rods. The angle between any two adjacent support rods is equal. The carrier rods have stop blocks at the upper part of the fixed connection between the carrier rods and the support rods.
