Abstract
A collapsible handcart comprises a handle bar, a support carrier having a main carrier and two movable carriers, two sets of linkages and a trigger.

The linkages are connected movable carriers with the main carrier such that the movable carriers can be driven to move between an extended position, at which the movable carriers are away from the main carrier, and a collapsed position, at which the movable carrier close to the main carrier. The trigger has an end thereof pivoted on the handle bar whereby turn the handle bar will drive the trigger to move. The trigger can drive the movable carriers to move such that the movable carriers will be driven to the extended position when turns the handle bar to the extended position and will be driven to the collapsed position when turns the handle bar to the collapsed position.
