However, the suspended counterweight is easily touched by accident, causing it to sway. In addition, the height of the limb suspension needs to be adjusted according to the actual recovery situation, which means that the counterweight needs to be replaced frequently, increasing the workload. There is room for technical improvement. Utility Model Content
