In this embodiment, the outer surface of each stopping portion 521 is smooth and can be inserted into the gap between adjacent spokes of the corresponding hub, the shape of each sliding portion 522 is spherical, and the size of each sliding channel 511 is matched with the size of the corresponding sliding portion 522.

Preferably, the outer end of each pin 52 is formed with a limit protruding ring 523 protruding outward along the circumferential direction, the outer end of the pore passage of the first shaft hole 1221 is provided with a limit step 1222, the outer end of each pin 52 is sleeved with a return spring 524, each return spring 524 is limited between the corresponding limit protruding ring 523 and the limit step 1222, and each return spring 524 makes the corresponding pin 52 have a tendency that the sliding portion 522 thereof slides downward into the corresponding second limit portion 5112, and the stop portion 521 abuts against the hub of the corresponding wheel 4. In this way, when the wheels 4 are unlocked, the pins 52 can be returned to the locked state of the wheels 4 by the corresponding return springs 524 by depressing the pedals 51, thereby facilitating the locking of the wheels 4. In addition, in order to facilitate the installation of each slide 511, the left and right ends of the bottom of the pedal 51 respectively extend downward vertically to form extension walls 512, the middle of each extension wall 511 is recessed inward to form a mounting groove 5121 on the outer side of each extension wall 512, a second mounting protrusion 5112 is formed on the inner side of each extension wall 512, each slide 511 is respectively arranged on the corresponding second mounting protrusion 5112 in an inner-outer penetrating manner, each first limiting portion 5111 is formed by vertically extending the lower end of the corresponding slide 511 downward, each second limiting portion 5112 is formed by vertically extending the upper end of the corresponding slide 511 upward, and each first limiting portion 5111 and each second limiting portion 5112 are respectively matched with the size of the corresponding slide 522.

Further, in this embodiment, a rechargeable battery 91 is installed in an inner space enclosed by the upper case 12 and the base 11, and the rechargeable battery also includes a power cord 92, a waterproof socket 93 and a wire spool 123 for winding the power cord 92 are respectively disposed on a rear side surface of the upper case 12, and in addition, a first switch 94 for controlling on/off and a second switch 95 for controlling brightness are respectively disposed on a right side surface of the upper case 12.
