[0049] Detailed explanation of usage: When performing emergency treatment for heat stroke, an emergency backpack will be used for operation. However, the internal space of the emergency backpack is limited, and the number of emergency instruments and medicines that can be stored is very limited. It has obvious limitations in practical applications, which makes it impossible to conveniently carry a large number of medical supplies to treat heat stroke patients. At this time, in order to facilitate the expansion of the entire backpack, the extension belt 43 and the positioning component 47 in the adjustment device 4 are used for auxiliary operation, thereby facilitating the convenient use of the entire backpack.

[0050] In order to conveniently operate the backpack, the extension belt 43 is used to expand the space between the upper backpack body 1 and the lower backpack body 2, and then the connecting frame 44 fixed to the upper backpack body 1 is connected with the fixing frame 41 on the lower backpack body 2, and the binding belt 42 is stretched and limited to fix, so that the roller 46 on the connecting frame 44 and the positioning frame 45 can fix the entire binding belt 42, and the position of the entire binding belt 42 can be fixed by the fixing strip 48, which is convenient for limiting the binding of the excessively long binding belt 42. When the binding belt 42 on the connecting frame 44 and the positioning frame 45 is slidably limited, in order to better fix the binding belt 42, the sliding rod 471 on the positioning frame 45 is used to slide the binding belt 42. The tension generated by the first spring 472 on the rod 471 squeezes the position of the entire extrusion plate 473 and the extrusion block 474, so that the entire restraint belt 42 can be fixed to prevent it from falling off. When the position of the extrusion plate 473 is adjusted and moved, the limiting rod 475 on the extrusion plate 473 can be used to conveniently limit and fix it. By operating the adjustment device 4, the extension belt 43 is used to expand the space between the upper backpack body 1 and the lower backpack body 2, and then the connecting frame 44 fixed on the upper backpack body 1 is connected to the fixing frame 41 on the lower backpack body 2, and the restraint belt 42 is stretched and limited and fixed, and the roller 46 and the positioning frame 45 on the connecting frame 44 fix the entire restraint belt 42.

[0051] When the entire backpack is used for a long time, in order to reduce the burden of the backpack on the human body, the support frame 51 fixed on the lower bag body is used for support and limitation, and then the support frame 53 on the bottom surface of the support frame 51 is used to slide with the roller 54, so that the entire backpack can slide, and then the rotation shaft 58 on the support frame 53 and the sliding shaft 57 are squeezed and fixed, so that the position of the roller 54 on the entire sliding shaft 57 can be adjusted, so that the entire backpack can be conveniently and effectively operated. After adjusting the entire roller 54, in order to facilitate the support and limitation of the support frame 53, the support frame 53 is used. The support pad 59 fixed on the support frame 53 is used for auxiliary operation. When the support frame 51 is used to support and limit the entire backpack, the protective frame 52 in the support frame 51 can effectively avoid direct collision and damage to medical supplies. By operating the moving device 5, the support frame 53 on the bottom surface of the support frame 51 and the roller 54 are used to slide, so that the entire backpack can slide, and then the extrusion and fixation between the rotating shaft 58 on the support frame 53 and the sliding shaft 57 are used to adjust the movement of the roller 54 on the entire sliding shaft 57, so that the entire backpack can be conveniently and effectively operated.

[0052] When the upper backpack body 1 and the lower backpack body 2 are operated and used together with the shoulder strap 3 for a long time, the shoulder strap 3 on the backpack is prone to breakage. At this time, in order to facilitate the replacement and position limiting of the shoulder strap 3, the rotating frame 602 rotating on the inlay plate 601 is docked with the rotating docking frame 603 on the shoulder strap 3 through the inlay plate 601 fixed on the backpack, and the fixed plate 604 on the rotating frame 602 is plugged and limited with the docking plate 605 on the docking frame 603, and then the inlay frame 606 on the docking frame 603 is used to allow the tension generated by the third spring 608 on the inlay frame 606 to abut and fix the inlay frame 606 and the fixing hole 609 to limit the position, so as to facilitate the replacement and position limiting of the entire shoulder strap 3. The arc-shaped protective pad 611 on the shoulder strap 3 can effectively protect the shoulder and avoid excessive friction during long-term use. By operating the auxiliary device 6, the fixed inlay plate 601 on the backpack is limited, so that the rotating frame 602 rotating on the inlay plate 601 is docked with the rotating docking frame 603 on the shoulder strap 3, and the fixed plate 604 on the rotating frame 602 is plugged and limited with the docking plate 605 on the docking frame 603, and then through the inlay frame 606 on the docking frame 603, the tension generated by the third spring 608 on the inlay frame 606 causes the inlay frame 606 to abut and fix with the fixing hole 609, so as to facilitate the replacement and limit fixation of the entire shoulder strap 3.
