[0035] See also Figure 1-Figure 5 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0036] Convenient assembly, the convenient assembly includes a connecting shell 21, a mounting groove 22, a square groove 23, a rotating shaft 24, a coil spring 25 and a connecting ring 26. The connecting shell 21 is fixed to the middle part of one side of the outer surface of the lightweight shell 11, the mounting groove 22 is opened on one side of the outer surface of the connecting shell 21, the square groove 23 is opened at the center of one side of the outer surface of the connecting shell 21, the rotating shaft 24 rotates and penetrates the outer surface of the connecting shell 21, the coil spring 25 is installed on both sides of the outer surface of the rotating shaft 24, and the connecting ring 26 penetrates the outer surface of the rotating shaft 24;

[0037] The outer surface of the connecting ring 26 is connected to a connecting rope 27 , and the outer surface of the connecting rope 27 is penetrated by a stopper 28 ;

[0038] The connecting shell 21 is used to install the rotating shaft 24 and the coil spring 25. The coil spring 25 provides elastic force for the rotating shaft 24 so that it can return to its original position automatically. The movement of the rotating shaft 24 can be controlled by pulling the connecting rope 27 to realize a manual control mechanism.

[0039] Working principle:

[0040] When carrying the battery, the user only needs to pull the stopper 28 and pull the connecting rope 27 outward. At this time, the rotating shaft 24 rotates, and the connecting rope 27 is pulled out from the surface of the rotating shaft 24. The user can directly hold the connecting rope 27 with his arm without holding it. When the battery is no longer needed, the user releases the arm, and the coil spring 25 will quickly recover its deformation, driving the rotating shaft 24 to rotate in the opposite direction. The connecting rope 27 will rotate and wrap around the outer surface of the rotating shaft 24, and the stopper 28 will be stuck outside the square groove 23, making it easy to use next time. This avoids the inconvenience caused by traditional carrying methods and is particularly suitable for long-distance travel or heavy work tasks. The user can save more energy and time and focus on other important matters.

[0041] In this step, through simple operations, the connecting rope 27 can be quickly pulled out and used to be hung on the arm, making it easy and free to carry the battery.
