The adjusting assembly includes a rotating component driven by the power mechanism, a guiding component fixed on the body, and multiple slot-pins. The guiding component includes a guide channel used for annular position limiting of the slot-pin and multiple position limiters used for longitudinal position limiting of the slot-pin, and the rotating of the rotating component enables the sliding of the slot-pin within the guide channel. The invention further provides a Multi-slot track combined raceway on which the slot car travels. With the adjusting assembly, the slot car is enabled to switch between tracks. The slot car is enabled to freely intercept its counterparts by switching tracks, thus the entertainment is enhanced. ## Claims ### Claim 1 A slot car comprising a body and a power mechanism for driving the body, further comprising an adjusting assembly used for track switching of the body, wherein the adjusting assembly includes a rotating component driven by the power mechanism, a guiding component fixed on the body, and a plurality of slot-pins, the guiding component includes a guide channel used for annular position limiting of the slot-pin and a plurality of position limiters used for longitudinal position limiting of the slot-pin, and the rotating of the rotating component enables the sliding of the slot-pin within the guide channel. ### Claim 2 (depends on 1) The slot car of claim 1, wherein the guide channel comprises a lower spot along a longitudinal direction of the guide channel. ### Claim 3 (depends on 2) The slot car of claim 2, wherein the guiding component comprises an annular shell fixed on the body, and the guide channel is provided on an internal wall of the shell. ### Claim 4 (depends on 2) The slot car of claim 2, wherein the guiding component comprises an annular shell fixed on the body, the shell is provided internally with a cylinder fixedly, and the guide channel is fixed on the cylinder. ### Claim 5 (depends on 2) The slot car of claim 2, an identity coding module used for recording a race result is provided in the body, and the identity coding module includes an interface for transmitting information to the Internet. ### Claim 6 (depends on 1) The slot car of claim 1, wherein the guide channel comprises two lower spots arranged symmetrically along a longitudinal direction of the guide channel. ### Claim 7 (depends on 3) The slot car of claim 3, wherein the guiding component comprises an annular shell fixed on the body, and the guide channel is provided on an internal wall of the shell. ### Claim 8 (depends on 6) The slot car of claim 6, wherein the guiding component comprises an annular shell fixed on the body, the shell is provided internally with a cylinder fixedly, and the guide channel is fixed on the cylinder. ### Claim 9 (depends on 6) The slot car of claim 6, an identity coding module used for recording a race result is provided in the body, and the identity coding module includes an interface for transmitting information to the Internet. ### Claim 10 (depends on 1) The slot car of claim 1, wherein the guiding component comprises an annular shell fixed on the body, and the guide channel is provided on an internal wall of the shell. ### Claim 11 (depends on 10) The slot car of claim 10, an identity coding module used for recording a race result is provided in the body, and the identity coding module includes an interface for transmitting information to the Internet. ### Claim 12 (depends on 1) The slot car of claim 1, wherein the guiding component comprises an annular shell fixed on the body, the shell is provided internally with a cylinder fixedly, and the guide channel is fixed on the cylinder. ### Claim 13 (depends on 1) The slot car of claim 1, wherein the position limiter is a U-shaped chute. ### Claim 14 (depends on 1) The slot car of claim 1, wherein the position limiter comprises two parallel baffles. ### Claim 15 (depends on 1) The slot car of claim 1, wherein the slot-pin comprises a positioning end and a guiding end arranged perpendicularly with respect to the positioning end. ### Claim 16 (depends on 1) The slot car of claim 1, wherein the rotating component comprises a connecting pole connected with the power mechanism, and the connecting pole is fixedly connected with the plurality of position limiters. ### Claim 17 (depends on 16) The slot car of claim 16, wherein the rotating component includes a base, on which the connecting pole and the position limiters are fixed. ### Claim 18 (depends on 17) The slot car of claim 17, an identity coding module used for recording a race result is provided in the body, and the identity coding module includes an interface for transmitting information to the Internet. ### Claim 19 (depends on 1) The slot car of claim 1, an identity coding module used for recording a race result is provided in the body, and the identity coding module includes an interface for transmitting information to the Internet. ### Claim 20 (depends on 1) A Multi-slot track combined raceway on which the slot car of claim 1 travels, comprising a plurality of connected tracks, wherein the tracks includes a plurality of recessed track slots used for engaging with a slot-pin of the slot car, and an adjust component of the slot car is used for adjusting the movement of the slot-pin within the track slot so that the slot car is allowed to switch from one track slot to another track slot.
