DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Combination Figures 1 to 5 The utility model is described in detail. The utility model relates to a load-reducing backpack, comprising a backpack body 1 and two shoulder straps 2; the shoulder straps 2 are fixed to the rear part of the backpack body 1.

[0024] The backpack body includes a main compartment 3 and a secondary compartment 4 for accommodating items; an upper zipper bag 5 and a lower front bag 6 are arranged on the front panel of the backpack body 1. The backpack used by students is a standard four-open bag structure, that is, it includes a main compartment 3, a secondary compartment 4, an upper zipper bag 5 and a lower front bag 6. The four-open bag structure can optimize the use. The main compartment 3 is used to place books. The secondary bag 4 opens to the bottom of the backpack and has a large capacity. It can place rolls of paper or books. The upper zipper bag 5 has a relatively suitable capacity for placing small items, and the lower front bag 6 can be used to place items such as red scarves.
