A support vertical rod 6 is installed on each of the four guide support slides 1, 2, 3, 4, and 5. The lower end of the support vertical rod 6 passes through the guide support slides 1, 2, 3, 4, and 5 and is fixedly connected to the front wheel 7 and rear wheel 8 below. A positioning seat 9 and a movable connecting seat 10 are installed on each of the four support vertical rods 6. The two ends of the folding and collapsing front support frame 11, folding and collapsing rear support frame 12, folding and collapsing side frame 13, and folding and collapsing side frame 2 14 are respectively fixed to the positioning seat 9 and the movable connecting seat 10 on the four support vertical rods 6.

[0019] The folding support base 1 consists of a guide support base 101, a guide support base 2 102, a front and rear connecting seat 103, a front and rear connecting seat 2 104, a guide seat 105, and a double X-shaped folding frame 106. The guide support base 101 and the guide support base 2 102 are arranged parallel to each other. The front and rear connecting seats 103 and 2 104 are respectively provided in the middle of the guide support base 101 and the guide support base 2 102, and are fixedly connected by positioning pins. Several guide seats 105 are provided on both the first guide support base rod 101 and the second guide support base rod 102. Two sets of double X-shaped folding frames 106 are provided between the first guide support base rod 101 and the second guide support base rod 102. The upper and lower ends of the two sets of double X-shaped folding frames 106 are fixedly connected to several guide seats 105 respectively.
