Stroller

A stroller comprising:

• a front leg;
• a rear leg rotatably connected to the front leg;
• a handle assembly rotatably connected to the front leg, the handle assembly comprising a lower handle portion and an upper handle portion rotatable relative to the lower handle portion, the upper handle portion and the lower handle portion being tubular structures;
• and
• a locking component movably disposed on the handle assembly, the locking component engaging with the front leg for restraining rotation of the handle assembly relative to the front leg in a first pivoting direction, the locking component being further driven by a rotating movement of the upper handle portion relative to the lower handle portion in a second pivoting direction opposite to the first pivoting direction to disengage from the front leg for allowing the rotating movement of the handle assembly relative to the front leg in the first pivoting direction during the rotating movement of the upper handle portion relative to the lower handle portion in the second pivoting direction;
• wherein the handle assembly and the front leg cooperatively engage with the rear leg for restraining a rotating movement of the rear leg relative to the front leg when the locking component engages with the front leg.
