Abstract

The invention relates to the technical field of knapsacks, and discloses a multi-functional backpack convenient for reducing spine load. The backpack comprises a backpack; the backpack is composed of a main body, a reciprocating device, an adjusting device, storage devices, a buffer layer, a supporting device and straps; the interior of the main body is movably connected to the reciprocating device; the bottom of the reciprocating device is fixedly connected to the adjusting device; the adjusting device is movably connected to the main body; the storage devices are arranged in two groups, and the two groups of storage devices are fixedly connected to the two sides of the main body respectively; the buffer layer is fixedly connected to one end of the main body, and the interior of the buffer layer is movably connected with the supporting device; and the straps are fixedly connected with the buffer layer. By means of the supporting device in the buffer layer, when the backpack is carried on the back, supporting for the backpack is assisted, the backpack can be attached to the spine of the back, the situation that the touching feeling of the back of a user is too hard is avoided, and therefore the comfort of the backpack is improved, and the load on the spine is reduced.
