Abstract

The invention discloses a portable school bag with a labor-saving device. The structure comprises a connecting base, an automatic tightening device, a fixing surface layer, a bag body, a moving rod and a hand grip, and the hand grip is nested above the moving rod. The handle bar is connected to the one end pull rod by an interference fit, and the automatic tightening device is embedded and connected to the inside of the connection base, and the fixed surface layer is stitched to the rear side surface of the main body of the bag by a connecting line. One end of the bottom of the moving rod is connected to the connecting base, and the upper part of the moving rod passes through the inner surface of the fixing surface layer and is in close contact with the main body of the bag body. The structure realizes that the bag with the labor-saving device can effectively fix the bag securely when used, avoiding shaking left and right when pulling, which is more labor-saving. Moreover, the bottom of the automatic tightening device can buffer the bag by providing a spring, and reduce the vibration inside the bag, which is beneficial to protect the stationery inside the bag and enhance the practicability.
