In the initial state, the threaded sleeve is coupled to the threaded rod by the coupling structure 98 and is not able to rotate continuously.
The process of attaching the bolt 9 into the exhaust hole in this embodiment is: the threaded sleeve is screwed into the threaded rod by rotating the bolt, when the threaded rod of the inner bolt is screwed to abut against the first step 92, the axial rod body 982 is extruded to enable the axial rod body to contract inwards, the axial rod body contracts inwards as a result of the axial rod body being inserted into the driving hole 988 to drive the radial rod body to contract inwards to be separated from the annular clamping groove 985, and after separation, the threaded rod can rotate relative to the threaded sleeve. In this process, the axial rod pop-up spring 983 and the radial rod pop-up spring 987 store energy. Further rotation of the second bolt until the head of the bolt is inserted into the unthreaded bore section causes the seal 97 to sealingly connect the head of the bolt and the unthreaded bore section together. The specific sealing process of the sealing element is as follows: the annular sealing lip 973 is inserted into the annular sealing ring mounting groove 971 to annularly seal the lip-shaped air storage sealing ring 972, so that the annular air storage sealing ring is deformed to be sealed.
