Preferably, the side of the shoulder strap away from the support plate is provided with a cover cloth.

Preferably, a second limiting groove is formed between the covering cloth and the supporting plate, and the braces are in sliding connection with the second limiting groove.

Preferably, the rigid limiting belt is arranged on one side, away from the bag body, of the second elastic belt, and the length of the rigid limiting belt is longer than that of the second elastic belt.

Preferably, the support plate is made of polyethylene.

Preferably, the first elastic belt and the second elastic belt are both 10-15cm in length.

The beneficial effects of the utility model reside in that:

this both shoulders knapsack is subtract to shock attenuation makes the junction become elastic connection by rigid connection through first elastic webbing and second elastic webbing, the weight of two baldrics of distribution that can be balanced when bearing the knapsack, shock attenuation when reaching the use, the effect of subtracting the burden, through the flexible length of rigidity spacing band restriction second elastic webbing, prevent that it from exceeding the elasticity limit, guarantee the durability of second elastic webbing, slide along first spacing groove through the shoulder strap, prevent the baldric horizontal hunting, slide along the second spacing groove through the back strap, further improve the stationarity.
