[0017] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific rope 204 recorded in the above embodiment. For example, the rope 204 can be selected as a cotton yarn belt. The purpose of this setting is that cotton yarn has good air permeability and can effectively prevent the legs from becoming red, swollen, itchy due to long-term contact with it.

[0018] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific shaft 201 recorded in the above embodiment. For example, a bearing ring can be provided at the connection between the shaft 201 and the housing 101. The purpose of this setting is to prevent the shaft from breaking due to long-term use in this way.
