Disclosed is an improved structure of a scooter, which comprises at least an upright pole (10) and left and right carrier poles (20). A handle (30) and a front wheel (40) are arranged at the upper end and the lower end of the upright pole (10) thereof, respectively. The front ends of the left and right carrier poles (20) are pivotally arranged at the upright pole (10). Rear driving wheel groups with rear driving wheels (51) are installed at the rear ends thereof, respectively, and the front ends of the left and right carrier poles (20) are respectively connected to an extension arm (60). Sleeves (61) are arranged on the extension arm (60). The sleeves (61) are mutually and movably pivoted on the upright pole (10) in a freely rotating and vertically corresponding manner. Retracting and folding modules (70) are arranged between the extension arm (60) and the left and right carrier poles (20). Each retracting and folding module (70) is provided with a pivot bolt (71) and an adjusting piece (72). The pivot bolts (71) are arranged between the extension arm (60) and the left and right carrier poles (20). Each adjusting piece (72) is located at one side of the pivot bolt (71). The adjusting pieces (72) lock the left and right carrier poles (20) onto the extension arm (60), and the carrier poles retract from the extension arm (60) through the adjusting pieces (72), so that the left and right carrier poles (20) are retracted and folded by moving in the direction parallel to the upright pole (10) with the pivot bolts (71) as an axis. |
