[0029] Among them, the positioning structure further includes a sub-magic tape 102, a mother magic tape 103, and a dust-proof foot pad 104; there are multiple sub-magic tapes 102, and the multiple sub-magic tapes 102 are evenly distributed and fixedly connected to the upper end faces of the first support body 1 and the second support body 2; there are multiple mother magic tapes 103, and the multiple mother magic tapes 103 are respectively adhered to the upper parts of the multiple sub-magic tapes 102; there are two dust-proof foot pads 104, and the two dust-proof foot pads 104 are respectively fixedly connected to the upper parts of the multiple mother magic tapes 103.

[0030] Among them, the anti-slip structure includes fixed anti-slip strips 201 and a third reset elastic member 501; there are multiple fixed anti-slip strips 201, and the multiple fixed anti-slip strips 201 are evenly distributed and fixedly connected to the upper end face of the second support body 2; the limiting compression inclined block 5 is elastically connected to the first support body 1 through the third reset elastic member 501.

[0031] Among them, the anti-slip structure further includes sliding anti-slip strips 301 and second reset elastic members 302; a plurality of sliding anti-slip strips 301 are provided, and the plurality of sliding anti-slip strips 301 are evenly distributed and fixedly connected to the upper end surface of the sliding connection plate 3; a plurality of second reset elastic members 302 are provided, and the sliding connection plate 3 is elastically connected to the first support body 1 through the plurality of second reset elastic members 302.

[0032] The specific usage method and function of this embodiment: When it is necessary to install the booster on a bicycle for use, flip the first support body 1 so that the first support body 1 coincides with the second support body 2. At this time, the first positioning magnets 101 adsorb each other to limit the first support body 1, and fix the second support body 2 under the bicycle seat through the positioning bolts, and adjust the angle of the booster so that the roller is close to the wheel. When it is necessary to unfold the booster for use as a skateboard, separate the first support body 1 and the second support body 2. At this time, the second positioning magnets 105 adsorb each other to limit the positions of the first support body 1 and the second support body 2. Place the booster on the ground, step on the sliding anti-slip strips 301 to make the sliding connection plate 3 and the limit extrusion inclined block 4 slide downward. When the limit extrusion inclined block 4 slides, it will squeeze the limit pressure-receiving inclined block 5, so that the limit pressure-receiving inclined block 5 drives the position-limiting insertion rod 6 to slide to the right. At this time, the position-limiting insertion rod 6 moves out of the position-limiting hole 8, and the roller connecting shaft 7 is no longer limited, and the roller can roll when the booster moves. After the child gets off the booster, the second reset elastic member 302 will push the sliding connection plate 3 to reset, and the third reset elastic member 501 will push the limit pressure-receiving inclined block 5 to reset, so that the position-limiting insertion rod 6 is inserted into the corresponding position-limiting hole 8 to limit the roller connecting shaft 7. If the position-limiting insertion rod 6 is not aligned with the position-limiting hole 8, when the booster slides, the roller connecting shaft 7 will rotate to adjust the angle of the position-limiting hole 8. After the position-limiting hole 8 is aligned with the position-limiting insertion rod 6, the position-limiting insertion rod 6 will automatically snap into the nearest position-limiting hole 8. The fixed anti-slip strip 201 and the sliding anti-slip strip 301 can increase the friction between the shoes and the booster. When it is necessary to clean the stepping surface of the booster, tear off the dust-proof foot pad 104 and the female magic tape 103 from the male magic tape 102 and clean the dust-proof foot pad 104 separately.

[0033] Embodiment Two: As Figures 4 to 8 shown: On the basis of Embodiment One, it further includes a traction structure; the traction structure is arranged on the right side of the first support body 1.

[0034] Among them, the traction structure includes a positioning installation box 106, a transmission winding shaft 107, and a reset scroll spring 112; the positioning installation box 106 is fixedly connected to the right side of the first support body 1; the transmission winding shaft 107 is rotatably connected to the middle of the positioning installation box 106; the transmission winding shaft 107 is elastically connected to the positioning installation box 106 through the reset scroll spring 112.

[0035] Among them, the traction structure further includes a direction-limiting ratchet 108 and a limit installation shaft 109; the direction-limiting ratchet 108 is fixedly connected to the upper part of the transmission winding shaft 107; the limit installation shaft 109 is rotatably connected to the upper part of the positioning installation box 106; the limit installation shaft 109 is elastically connected to the positioning installation box 106 through a limit scroll spring.

[0036] Among them, the traction structure further includes a direction-limiting pawl 110 and a first reset elastic member 111; the direction-limiting pawl 110 is splined to the upper part of the limit installation shaft 109; the direction-limiting pawl 110 is elastically connected to the limit installation shaft 109 through the first reset elastic member 111, and the direction-limiting pawl 110 and the direction-limiting ratchet 108 together form a ratchet transmission mechanism.

[0037] Among them, the traction structure further includes a traction rope 113 and a rubber pull ring 114; the traction rope 113 is fixedly connected to the outside of the transmission winding shaft 107; the traction rope 113 is wound around the outside of the transmission winding shaft 107 and sequentially passes through the positioning installation box 106 and the first support body 1 and is fixedly connected to the rubber pull ring 114.

[0038] The specific usage mode and function of this embodiment: After the power of the booster is exhausted, fold the booster, and then pull the rubber pull ring 114 to pull out the traction rope 113. At this time, the child can pull the booster back. During the process of pulling out the traction rope 113, the traction rope 113 will drive the transmission winding shaft 107 and the direction-limiting ratchet 108 to rotate in the positioning installation box 106. At this time, the direction-limiting pawl 110 and the limit installation shaft 109 will swing along the outer edge of the direction-limiting ratchet 108 and at the same time limit the transmission winding shaft 107 and the direction-limiting ratchet 108 from reversing. When it is necessary to rewind the traction rope 113, push down the direction-limiting pawl 110 so that the direction-limiting pawl 110 no longer contacts the direction-limiting ratchet 108. At this time, the reset scroll spring 112 will drive the transmission winding shaft 107 and the direction-limiting ratchet 108 to reverse and wind up the traction rope 113. After the winding is completed, release the direction-limiting pawl 110, and the first reset elastic member 111 will push the direction-limiting pawl 110 back to its original position.
