The inner rings of the two groups of torsion springs 55 are installed correspondingly to the outer rings at both ends of the mounting column 54. One end of the two groups of torsion springs 55 is installed correspondingly to the stabilizing frame 51. One end of the torsion spring 55 is fixedly connected to the stabilizing frame 51. The other end of the torsion spring 55 is installed correspondingly to the adjusting pedal 53. The other end of the stabilizing frame 51 is fixedly connected to the inner wall of the connecting hole on the adjusting pedal 53. The arrangement of the two groups of torsion springs 55 makes it easy for the operator to quickly drive the standpipe body 1 and the adjusting tube 2 to flip and fold by connecting the folding frame 4. At the same time, it is easy for the operator to quickly buckle the adjusting pin 52 with a group of card slots 12 by stepping on the adjusting pedal 53. A positioning pin is provided on the inside of the stabilizing frame 51.The positioning pin is threadedly connected to the stable frame 51, and the positioning pin can be manually disassembled and assembled. The setting of the positioning pin can prevent the adjusting pin 52 from sliding freely in the limiting slide groove when the adjusting pin 52 is correspondingly buckled with the card slot 12, thereby making the connected folding frame 4 more stable when it is unfolded or folded. Protective outer panels 56 are provided on both sides of the stable frame 51. The two sets of protective outer panels 56 are installed on one side close to each other and on both sides of the stable frame 51. The two sets of protective outer panels 56 are fitted together on one side close to the two sides of the stable frame 51, and the two sides of the stable frame 51 are The two sets of protective outer panels 56 are each provided with a plurality of screw holes 1, each set of screw holes 1 being provided with a fixing bolt 13, which is threadedly connected to the screw holes 1. The provision of the fixing bolt 13 enables the protective outer panels 56 to be securely mounted on both sides of the stabilizing frame 51, thereby enabling the protective outer panels 56 to protect the stabilizing frame 51. The provision of the folding assembly 5 enables the connecting folding frame 4 to be stably unfolded, while facilitating the operator to flip and fold the standpipe body 1 and the adjustment tube 2 by connecting the folding frame 4, thereby reducing space occupied when the electric scooter is folded and stored, and facilitating handling and transportation.

[0021] A connecting mounting plate 6 is provided at the bottom of the stabilizing frame 51. The bottom of the stabilizing frame 51 is installed corresponding to one side of the connecting mounting plate 6. One side of the stabilizing frame 51 is fitted with the top of the connecting mounting plate 6.

The fixing bolt 2 14 is threadedly connected to the screw hole 2. The setting of the fixing bolt 2 14 can make the stabilizing frame 51 firmly installed on the connecting mounting plate 6. The overall structure of this mechanism is simple and easy to operate. The operator can adjust the height of the standpipe body 1 by setting the spring pin 8 and the pin hole 9. At the same time, the setting of the folding component 5 and the card slot 12 can make the connecting folding frame 4 more stable when folding and unfolding, thereby reducing the space occupied by the electric scooter when folded and stored, and making it more stable when unfolded, which is beneficial for the operator to ride the electric scooter safely.

[0022] The folding frame 4 is rotated on the inner wall of the stabilizing frame 51 through the positioning column 57. The rotation of the folding frame 4 drives the vertical pipe body 1 and the adjusting pipe 2 to rotate accordingly through the fixed connecting sleeve 3. When the folding frame 4 rotates, the other group of grooves 12 on the folding frame 4 moves to the position of the limiting groove. The operator no longer steps on the adjusting pedal 53. The adjusting pedal 53 drives the two ends of the adjusting pin 52 to resume the locking state with the grooves 12 under the reset action of the torsion spring 55, so that the folding frame 4 drives the vertical pipe body 1 and the adjusting pipe 2 to complete the flipping and folding operation.

[0023] The above specific embodiment is only a preferred embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
