AI Technical Summary
When carrying an existing backpack, the connection structure connected to the two corners of the backpack if the backpack is placed too long will prevent the backpack from being close to the back of the human body, resulting in the center of gravity away from the human body, which can easily sprain the waist. At the same time, maintaining a bad posture for a long time will lead to deformation of the back posture.
A labor-saving spine protection schoolbag is designed, including a load-bearing plate, slider and slide chute structure. The position of the fixed block is adjusted by sliding the slider in the slide chute, combining elastic shoulder straps and correction plates to ensure that the schoolbag is close to the back, corrects the posture, and conforms to the ergonomic design.
It effectively avoids the shift of the schoolbag center of gravity, improves the comfort and safety of carrying, corrects bad posture, and protects the health of the waist and back.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of learning utensils, in particular to a labor-saving spinal protection schoolbag. Background Art
[0002] A double-shoulder schoolbag is a learning utensil used to place books. At present, when using an existing double-shoulder schoolbag, the schoolbag body is hung on the collarbone protrusion positions on the two shoulders of a human body through two shoulder straps. The main stress points are concentrated on the collarbone. When a carrier carries a relatively heavy schoolbag for a long time, it is easy to feel fatigued. The lower part of the shoulder strap is connected to the two corners of the schoolbag. If the shoulder strap is too long, this connection structure will cause the backpack not to fit closely to the human back, the center of gravity of the backpack is far from the human body, and it is easy to sprain the waist. At the same time, when carrying an ordinary double-shoulder backpack, a person will naturally exert force forward with both shoulders. Maintaining this posture for a long time will cause the back posture to deform. Summary of the Utility Model
