The connection of oil pocket, resistance oil, stirring bar, oil sealing, big envelope, retainer, annular driving cog and Connection Block as shown in Figure 1, at first oil-sealing sleeve on stirring bar, allow the square step of stirring bar pass big envelope then, insert the square hole of retainer, and the button of stirring bar blocks retainer; Allow annular driving cog be enclosed within on the step cutting pattern of retainer then, allow the concave station rank of Connection Block link to each other, and the button of retainer blocks Connection Block with the step cutting pattern top of retainer; Inject a certain amount of resistance oil then in oil pocket, allow the circular shaft of stirring bar link to each other with the axle sleeve of oil pocket, the featheredge cavity of big envelope is connected the position with through hole and links to each other respectively with the step cutting pattern of stirring bar with the big envelope of oil pocket.
After adopting above scheme, the beneficial effects of the utility model are: the oil sealing compressing big envelope dynamics on the stirring bar is suitable, cushion effect scale standard.
