square block 12 to swing in the connecting square groove 11, the first rubber layer 19 is intermittently extruded and loosened, so that the lubricating hole 17 is intermittently sucked and supplied with air through the first cavity 20, so that power is provided for the lubricating oil, the lubricating oil flows, the infiltration effect is improved, and in the process that the connecting square block 12 is inserted into the connecting square groove 11, the honeycomb duct 24 is inserted into the insertion hole 22 to extrude the sealing film 23, so that the sealing film 23 is stretched, the opening of the sealing film 23 is enlarged and is wrapped on the outer wall of the honeycomb duct 24 to effectively seal the joint of the lubrication port 17, after the fixing of the inner hexagonal screw fastener is completed, the fastener fixing block 3 is taken down, when the inner hexagonal screw fastener needs to be disassembled, the connecting square block 12 on the fastener fixing block 3 is inserted into the connecting square groove 11 to disassemble the inner hexagonal screw fastener, after the inner hexagonal screw fastener is repeatedly disassembled and installed, the fastener fixing block 3 can cause the damage of the hexagonal wrench groove 5 due to long-term use, at the moment, only the fastener fixing block 3 needs to be replaced without replacing the whole inner hexagonal screw fastener, after the fastener fixing block 3 is taken down, the honeycomb duct 24 is separated from the insertion hole 22, the sealing film 23 is recovered, and the insertion hole 22 is effectively sealed, after the fastener fixing block 3 is removed, the guide pipe 24 is separated from the inserting opening 22, and when the connecting pin bolt 4 is inserted into the first through hole 9 again, the second rubber layer 25 in the first through hole 9 is extruded, so that gas in the second cavity 26 enters the third cavity 27, the gas in the third cavity 27 is in a high-pressure state, the sealing membrane 23 is expanded, and the diameter of an opening hole in the sealing membrane 23 is reduced.
