[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Referring to Figures 1 - 3 , a single-soldier carrying backpack includes a backpack main body 1. A bottom plate 2 is fixedly connected to the lower end of the backpack main body 1. A threaded hole 3 is opened inside the bottom plate 2. A screw 4 is threadedly connected inside the threaded hole 3. A rotating block 5 is fixedly connected to the end of the screw 4 away from the threaded hole 3. The rotating block 5 is slidably connected to the bottom plate 2. By designing the rotating block 5, it can be used to drive the screw 4 to rotate. A wheel column 6 is movably connected to the outside of the screw 4. The wheel column 6 is slidably connected to the bottom plate 2. A wheel 7 is arranged inside the wheel column 6. A sliding groove 8 is opened inside the bottom plate 2. The screw 4 is slidably connected inside the sliding groove 8. By designing the sliding groove 8, the screw 4 can slide inside the sliding groove 8.

[0020] Referring to Figures 1 - 4 , a telescopic sleeve 9 is arranged inside the bottom plate 2. The screw 4 is in contact with the inside of the telescopic sleeve 9. A connecting sleeve 10 is connected to the upper end of the backpack main body 1. A sliding rod 11 is slidably connected inside the connecting sleeve 10. A handle 12 is fixedly connected to the upper end of the sliding rod 11. The handle 12 is made of iron material. By designing the handle 12 to be made of iron material, the handle 12 is made more durable.

[0021] Referring to Figure 2 、 Figure 4, a chute 13 is provided inside the sliding rod 11, a sliding rod 14 is slidably connected inside the chute 13, one end of the sliding rod 14 away from the chute 13 is fixedly connected with a pulling block 15, the pulling block 15 contacts the connecting sleeve 10. By designing the pulling block 15, it can be used to drive the sliding rod 14 to move. A pulling spring 16 is arranged on the outer side of the sliding rod 14, one end of the pulling spring 16 is fixedly connected with the pulling block 15, and the other end of the pulling spring 16 is fixedly connected with the connecting sleeve 10. By designing the pulling spring 16, the pulling block 15 has an elastic force. The sliding rod 14 is slidably connected inside the connecting sleeve 10. By turning the screw rod 4 out of the threaded hole 3, then moving the wheel 7 downward to a specified position, and then turning the screw rod 4 into another threaded hole 3, pulling the handle 12 drives components such as the sliding rod 11 to move upward to a specified position, so that the device can be pulled on flat ground, and the physical strength of personnel can be reduced for the device.

[0022] The specific implementation process of the present utility model is as follows: When the device is in use, rotate the rotating block 5, the rotation of the rotating block 5 drives the screw rod 4 to rotate. The rotation of the screw rod 4 has a threaded movement with the threaded hole 3, so that the screw rod 4 generates a relative displacement. The screw rod 4 rotates out of the threaded hole 3, and then move the rotating block 5 downward. The downward movement of the rotating block 5 drives the screw rod 4 to move downward. The downward movement of the screw rod 4 drives the wheel column 6 to move downward. The downward movement of the screw rod 4 causes the telescopic sleeve 9 to expand and contract. The downward movement of the wheel column 6 drives the wheel 7 to move downward. After the wheel 7 moves downward to a specified position, turn the screw rod 4 into another threaded hole 3, so that the wheel 7 is limited. Then pull the pulling block 15 to move away from the connecting sleeve 10. The movement of the pulling block 15 drives the sliding rod 14 to move. The movement of the pulling block 15 stretches the pulling spring 16. The pulling block 15 moves out of the chute 13. Then move the handle 12 upward. The upward movement of the handle 12 drives the sliding rod 11 and the chute 13 to move upward to a specified position. Then release the pulling block 15. The pulling force of the pulling spring 16 drives the pulling block 15 to move. The movement of the pulling block 15 drives the sliding rod 14 to move. The sliding rod 14 moves into another chute 13, so that components such as the handle 12 are limited, and the device can be pulled on flat ground, and the physical strength of personnel can be reduced for the device.

[0023] The above is only a preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
