A foldable toy stroller includes two main rods and two extension rods whose upper ends are mounted to lower ends of the main rods. Lower ends of the extension rods are rotatably mounted to two ends of a front-wheel base. A sliding seat is slidably mounted on a central rod having an end connected to the front-wheel base. Two rear wheel support rods are provided and each include a first end pivotably connected to the front wheel base and a second end to which a rear wheel is mounted. Pivotably connected to the sliding seat are two struts whose upper ends are pivotably connected to upper ends of the main rods. Two connecting rods are pivotably connected between the rear wheel support rods and the sliding seat. Each rear wheel support rod and each connecting rod are pivotable toward or away from the central rod for folding or unfolding operation.

I claim: 1. A foldable toy stroller comprising: two main rods each including an upper end and a lower end; a front-wheel base including two ends; two extension rods each including an upper end mounted to the lower end of one of the main rods and a lower end rotatably connected to one of the ends of the front-wheel base; a central rod including a first end connected to the front-wheel base and a second end, a locking member being mounted in the second end of the central rod and including a locking portion; a sliding seat slideably mounted on the central rod and including a positioning hole for receiving the locking portion of the locking member; two rear wheel support rods each including a first end pivotably connected to the front wheel base and a second end to which a rear wheel is mounted; two struts each including an upper end pivotably connected to the upper end of one of the main rods and a lower end pivotably connected to the sliding seat; and two connecting rods each including a first end pivotably connected to one of the rear wheel support rods and a second end pivotably connected to the sliding seat, with each of the rear wheel support rods and the connecting rods being pivotable away from the central rod for unfolding the foldable toy stroller or toward the central rod for folding the foldable toy stroller, with the locking portion of the locking member being engaged in the positioning hole of the sliding seat when the foldable toy stroller is in an extended state, with the struts being away from the central rod and stretching the main rods upward, and with the connecting rods being away from the central rod and stretching the rear wheel support rods outward away from the central rod, and with the sliding seat being slidable on the central rod when the locking portion of the locking member is disengaged from the positioning hole of the sliding seat, allowing the main rods, the rear wheel support rods, the struts, and the connecting rods to pivot toward the central rod for folding the foldable toy stroller. 2. The foldable toy stroller as claimed in claim 1, further comprising, in combination: a coupler mounted, on the upper end of each of the main rods; and two links mounted between the main rods and each including an inner end and an outer end, with the inner ends of the links being pivotably connected together, and with the outer ends of the links being respectively and pivotably connected to the couplers. 3. The foldable toy stroller as claimed in claim 1, with the sliding seat further including four connecting portions to which the lower ends of the struts and the second ends of the connecting rods are pivotably connected. 4. The foldable toy stroller as claimed in claim 1, with the sliding seat including a longitudinal hole that slideably receives the central rod, with the positioning hole of the sliding seat being in communication with and transverse to the longitudinal hole, with the sliding seat further including a guiding groove extending parallel to the longitudinal hole and in communication with the positioning hole, and with the locking portion being slideable in the guiding groove when the sliding seat is slideable on the central rod. 5. The foldable toy stroller as claimed in claim 1, the locking member further including an engaging portion, with the central rod including a first slot in a periphery thereof through which the locking portion of the locking member extends, with the central rod further including a second slot in the periphery thereof through which the engaging portion of the locking member extends, with the foldable toy stroller further comprising, in combination: a handle mounted to the second end of the central rod and including an engaging hole for receiving the engaging portion of the locking member; and a spring mounted in the central rod for biasing the locking portion and the engaging portion of the locking member to respectively engage with the positioning hole of the sliding seat and the engaging hole of the handle, with the handle further including a push button slideably received in the engaging hole of the handle and pressable to disengage the engaging portion of the locking member from the engaging hole of the handle and to disengage the locking portion of the locking member from the positioning hole of the sliding seat to allow sliding movement of the sliding seat along the central rod. 6. The foldable toy stroller as claimed in claim 1, with the front-wheel base including a vertical portion extending downward from an intermediate portion between the ends of the front-wheel base, with a front wheel being attached to the vertical portion, with the front-wheel base further including a horizontal portion extending horizontally from the intermediate portion and including an end to which a coupler is mounted, and with first end of the central rod being coupled to the coupler. 7. The foldable toy stroller as claimed in claim 6, with each of the ends of the front-wheel base including a stud extending outward from an end face thereof and at an acute angle with a longitudinal axis of the central rod, with the lower end of each of the extension rods including an eccentric hole parallel to and spaced from a central portion thereof and rotatably receiving the lower end of one of the extension rods, and with each of the studs defining a rotating axis for the lower end of one of the extension rods. 8. The foldable toy stroller as claimed in claim 6, with the coupler including two pairs of lugs on an outer periphery thereof, and with the front end of each of the rear wheel support rods being pivotably received between one of the pairs of lugs. 9. The foldable toy stroller as claimed in claim 6, with the sliding seat including a longitudinal hole that slideably receives the central rod, with the positioning hole of the sliding seat being in communication with and transverse to the longitudinal hole, with the sliding seat further including a guiding groove extending parallel to the longitudinal hole and in communication with the positioning hole, and with the locking portion being slideable in the guiding groove when the sliding seat is slideable on the central rod.
