When bumps occur, the recoil force of the cushioning cylinder 2 can cushion the load-carrying cushioning plastic bracket 3 and the backpack thereon, preventing the backpack from falling and increasing the burden on the user;

[0030] As attached Figure 1, Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown in , when the backpack falls downward due to the earth's gravity, the output end of the weight-reducing cylinder 2 is fixedly connected to the load-reducing rubber bracket 3, and the weight-reducing cylinder 2 pushes the load-reducing rubber bracket 3 to rise, and the load-reducing rubber bracket 3 pulls the elastic rope 8 fixed thereunder, and the elastic rope 8 passes through the guide wheels 9 staggeredly distributed up and down, and the guide wheels 9 limit and support the elastic rope 8, and the elastic rope 8 is deformed and pulls the load-reducing rubber bracket 3 to limit the load-reducing rubber bracket 3 to prevent the load-reducing rubber bracket 3 from shaking too much. When the load-reducing rubber bracket 3 descends, the buffer rubber blocks 12 symmetrically fixed on the backrest rubber frame 1 and the buffer rubber blocks 12 symmetrically distributed on the load-reducing rubber bracket 3 collide with each other, dissipating part of the force, achieving buffering, reducing the falling of the load-reducing rubber bracket 3, and reducing the burden on the user;

[0031] As attached Figure 1 , Attachment Figure 2 and attached Figure 4 As shown in the figure, when the load-carrying slow-down rubber bracket 3 slides, the side guide pulleys 4 symmetrically installed on the left and right sides of the rear side of the load-carrying slow-down rubber bracket 3 slide in front of the first clamping strip 5 connected to the clamping slot, and the middle bone guide pulley 6 installed in the middle of the rear of the load-carrying slow-down rubber bracket 3 slides on the outside of the second clamping strip 7. The middle bone guide pulleys 6 symmetrically distributed on the left and right fit closely with the second clamping strip 7, which can ensure the stability of the load-carrying slow-down rubber bracket 3 and prevent the load-carrying slow-down rubber bracket 3 from shaking left and right;

[0032] As attached Figure 2 , Attachment Figure 5 and attached Figure 6 As shown in the figure, when the tension of the elastic rope 8 needs to be adjusted, the adjustment handle 13 can be rotated on the backrest rubber frame 1, and the adjustment handle 13 drives the connecting block 15 installed on the rear side to rotate, and the connecting block 15 drives the connecting wheel 16 engaged on the left side to rotate, and the connecting wheel 16 drives the winding roller 10 integrated on the rear side to rotate, so that the winding roller 10 can wind the elastic rope 8 or release the elastic rope 8. The winding roller 10 is rotatably connected to the backrest rubber frame 1 through the reset spring 11, and the reset spring 11 provides support force for the winding roller 10. The outer side of the connecting block 15 is tightly fitted with a support spring 14 to provide support force for the connecting block 15. After the adjustment is completed, the winding roller 10 can be fixed with screws.
