A group of armrests 203 are respectively rotatably connected to the side walls of each group of lifting blocks 202. A gear 204 is fixedly sleeved at one end of the armrest 203 located inside the lifting block 202. Two groups of limit pins 205 extending into the inside of the back panel 201 are slidably connected to the inner wall of the lifting block 202. A rack 206 is fixedly connected to one end of each group of limit pins 205 located inside the lifting block 202. The two racks 206 are respectively located above and below the gear 204, and the two racks 206 are simultaneously engaged with the gear 204. A plurality of limit grooves 207 matching the limit pins 205 are opened on the inner wall of the back panel 201, and a headrest 3 is fixedly connected to the top end of the back panel 201.

[0032] Principle of this embodiment: By flipping the armrest 203 upwards, the armrest 203 drives the gear 204 to rotate. The gear 204 drives the two racks 206 to move, so that the two racks 206 simultaneously drive the two limit pins 205 to slide out of the limit groove 207. Then, the armrest 203 is pulled upwards, so that the armrest 203 drives the lifting block 202 to slide upwards on the side wall of the back panel 201, thereby increasing the height of the armrest 203. Then, the armrest 203 is rotated in the reverse direction, so that the armrest 203 drives the gear 204 to rotate in the reverse direction. At this time, the gear 204 pushes the two racks 206 to reset. The two racks 206 respectively drive the two limit pins 205 to move away from each other, so that the limit pins 205 are inserted into the corresponding limit grooves 207.

[0035] Principle of this embodiment: The sliding plate 104 is fixed to the scooter by using bolts, and multiple groups of fixing screw holes 105 at different positions can adapt to different installation positions. Before driving the scooter, the user pulls the turning handle 106, so that the turning handle 106 drives the rotating arm 107 in the reverse direction. The rotating arm 107 pushes the latch 108 during the flipping process, so that the latch 108 slides out from the inside of the limiting hole 109. At this time, the bottom plate 101 is pulled, so that the bottom plate 101 drives the first guide plate 102 and the second guide plate 103 on the sliding plate 1 04, thereby changing the front and rear position of the seat. When the front and rear position of the seat is adjusted to a suitable position, the turning handle 106 is released, and the reset spring 110 rebounds, thereby pushing the latch 108 to slide upward and insert into the corresponding limiting hole 109, so that the first guide plate 102 and the sliding plate 104 cannot slide, so that the position of the seat is fixed. During the resetting process of the latch 108, the latch 108 pushes the rotating arm 107 to flip back and reset, so that the rotating arm 107 drives the turning handle 106 to reset.
