1. A stroller comprising:a handle having two arm tubes; an actuating means operably mounted on the handle; two pivot locking means mounted to a free end of the two arm tubes respectively and connected to the actuating means via a cable; and two front leg tubes one end of each of the tubes being pivotally coupled to a corresponding one of the pivot locking means respectively and the other end being provided a front wheel, wherein the pivot locking means includes a locking portion, which is mounted to the front leg tube, a latching portion which is slidably installed in the arm tube of the handle and is operably coupled to the actuating means via the cable so as to selectively engage/disengage with the locking portion, a connecting member which nivotally counsel the handle to the locking portion, and a protecting cap which encloses the lacking portion, the latch portion, and the connecting member therein; and wherein the locking portion includes a mounting member, which is mounted to one end of the front leg tube, two hook members respectively disposed at either side of the mounting member, wherein each of the hook members has a hook with a slanted face and a notch formed at one side thereof. 2. A stroller as claimed in claim 1, wherein the handle is a substantially U-shaped tube member having a connection portion connecting the two arm tubes and the actuating means is mounted to the connection portion.3. A stroller as claimed in claim 1, wherein the latching portion includes a hollow cylindrical seat, which is fixedly mounded in the free end of the arm tube of the handle and has a bottom, a sidewall having longitudinal slots formed therein, and a top having a diameter greater than the inner diameter of the arm tube of the handle to prevent the seat from sliding into the arm tube; a sliding member which is slidably disposed in the seat and connected to the actuating member via the cable, a return spring disposed between the sliding member and the bottom of the seat, a pin transversely passing through the sliding member and extending out of the arm tube to selectively engage/disengage with the hook members.4. A stroller as claimed in claim 1, further comprising:two rear leg tubes one end of each of the tubes being pivotally counted to one of the front leg tubes at a position proximate to the front wheel respectively and the other end being provided a rear wheel; two connecting tubes one end of each of the tubes being pivotally coupled to one of the pivot locking means respectively and the other end being pivotally counted to one of the rear leg tubes; two swinging pins each rotatably mounted to a connecting tube respectively; a substantially U-shaped seat tube having two arm portions each respectively coupled to a connecting tube via the swinging pin; and a tray assembly mounted to free ends of the arm portions of the seat tube and pivotally counted to the front leg tubes, thereby the pivot locking means may selectively lock the stroller in an erected position where the handle is substantially parallel to the front leg tubes and the connecting tubes is substantially perpendicular to the ground, or unlock the stroller to allow the handle to be forwardly and downwardly folded and make the handle, the front leg tubes, the rear leg tubes, connecting tubes, seat tube, and the tray assembly to claps to a folded position. 5. A stroller as claimed in claim 1, wherein the latching portion includes a spring member fixedly disposed in the free end of the arm tube of the handle; a sliding member slidably disposed in the free end of the arm tube against the spring member and connected to the actuating member via the cable; and a pin transversely passing through the sliding member and extending out of the arm tube to selectively engage/disengage with the hook members.6. A stroller as claimed in claim 4, wherein the swinging pin has a middle portion, a first arm formed at one end of the middle portion and extending in a direction perpendicular to the middle portion, and a second arm formed at the other end of the middle portion and extending in a direction on the same plane of the first arm yet opposite thereto.7. A stroller as claimed in claim 4, wherein the tray assembly includes two mounting pieces each being mounted to a free end of the arm portion of the seat tube at a lower portion thereof and pivotally coupled to the front leg tube at an upper portion thereof, and a tray having two coupling arms for removably coupling to the mounting pieces.
