Claim:
A collapsible handcart, comprising: a support carrier having a main carrier and two movable carriers, wherein said movable carriers are movably coupled on lateral sides of said main carrier respectively to be driven for movement between a collapsed position, at which said movable carriers are close to said main carrier, and an extended position, at which said movable carriers are away from said main carrier by a predetermined distance so as to extend a support area of the support carrier for supporting goods with a larger size than can be supported by the main carrier; a handle bar having a grip at an end thereof and pivoting the other end thereof on said main carrier of said support carrier to be turned between a collapsed position, at which said handle bar is turned inwardly to said main carrier, and an extended position, at which said handle bar is turned outwardly from said main carrier by a predetermined angle; two wheels pivoted on said support carrier; a movable trigger provided at said main carrier of said support carrier and having an end thereof pivoted on said handle bar such that turning said handle bar will drive said trigger to move and said trigger can activate said movable carriers to move; whereby said movable carriers will be driven to move to the collapsed position via said trigger when said handle bar is turned to the collapsed position and said movable carriers will be driven to move to the extended position via said trigger when said handle bar is turned to the extended position; and two sets of linkages that are used to connect said movable carriers to said main carrier, and each set of said linkages has a first linkage and a second linkage with their ends pivoted on said main carrier and said movable carriers respectively.
