The utility model discloses further set up: each stop block is provided with a baffle surface, each stop hole inner wall is provided with a flange, and each baffle surface on the stop block is attached to the corresponding flange on the stop hole.
The technical scheme is adopted, and the method has the advantages that: the arrangement of the blocking surface and the blocking edge in the technology further improves the stability of the stop block in the stop hole, avoids the problems of separation of the upper gasket and the lower gasket or slipping between the upper gasket and the lower gasket, further avoids influencing the actual operation of an external tool,
the utility model discloses further set up: the end face of the upper gasket and the bottom face of the lower gasket are respectively provided with a connecting gasket which is used for being in contact with parts of an external connecting tool, and the connecting gaskets are made of polyurethane materials.
The technical scheme is adopted, and the method has the advantages that: the arrangement of the connecting pads improves the friction torque between the upper gasket and the lower gasket and the external bolt or nut, avoids the slipping phenomenon between the upper gasket and the external bolt or nut and between the lower gasket and the external bolt or nut, and further avoids influencing the actual operation of the external tool.
The utility model discloses further set up: the expansion spring is made of wear-resistant rubber.
The technical scheme is adopted, and the method has the advantages that: the expanding spring is made of the wear-resistant rubber material in the technology, so that the friction torque between the expanding spring and the annular groove is improved, and the phenomenon that the upper gasket rotates or slips relative to the lower gasket when the upper gasket and the lower gasket are coaxially stacked is avoided.
