In order to solve the problem in the prior art that various flywheel shells cannot be adapted, the present application provides an adjustable internal support structure between the sling and the flywheel shell, thereby enabling internal support for flywheel shells of different models, thereby achieving the effect of adapting to flywheel shells of different models and improving the applicability of the sling. Therefore, it is necessary to propose a new solution to solve this problem. Utility Model Content
