The ratchet sleeve (36) is fixedly mounted on the inner wall of the corresponding installation frame (11). The inner wall of the ratchet sleeve (36) is rotatably mounted with a ratchet (38) through a mounting block, and the ratchet (38) is engaged with the ratchet (37). An elastic sheet (39) for unidirectionally limiting the ratchet (38) is fixedly mounted on the mounting block where the ratchet (38) is located. A reset spring for rewinding the canvas roll (12) is also provided between the ratchet sleeve (36) and the end of the canvas roll (12).

10. The method for constructing a load-reducing backpack based on a human skeleton support according to any one of claims 1 to 9, characterized in that: The method comprises the following steps: S1: The backpack body (1) is carried on the shoulders through the shoulder strap (2). When the backpack is heavy, the movable frame (13) provided at the bottom of the mounting frame (11) can be pulled out, and the flexible gait following mechanism provided on the movable frame (13) can be turned down. The telescopic rod (7) can be manually adjusted so that the universal wheel (9) can be in contact with the ground. S2: When the student walks, the backpack body (1) can be supported by the adjustable telescopic rod (7), the elastic buffer rod (8) and the universal wheel (9), thereby achieving a load-reducing effect. Moreover, the front and rear buffer adjustment parts and the upper and lower buffer adjustment parts provided on the flexible gait following mechanism can realize front and rear swing buffer adjustment by the rotation setting of the swing bar (27) and the cooperation of the spring (26) when encountering uphill or downhill. At the same time, the elastic buffer rod (8) can be used to perform upper and lower height buffer adjustment for the fluctuation of the road surface. S3: Through the provided fixing mechanism, when encountering bad weather, after the umbrella is opened, the screw rod (32) is manually rotated. Since the screw rod (32) and the rod sleeve (33) are threadedly connected, the two rod sleeves (33) can be further driven to approach each other, thereby driving the two lower clamping blocks (30) and the upper clamping block (34) to approach each other. When the two lower clamping blocks (30) approach each other, the umbrella handle can be clamped and fixed. When the upper clamping blocks (34) approach each other, the umbrella handle can be clamped, thereby ensuring the effective fixation of the umbrella; S4: When the flexible gait following mechanism rotates 270 degrees clockwise, the universal wheel (9) is located at the upper part of the backpack body (1). Since the universal wheel (9) is at a high position, the light-emitting module provided thereon can achieve a warning effect in bad weather.
