Pass through said structure, in the process that end cover seals high-pressure bottle, end cover is under the effect of suspension mechanism, be in an equilibrant force state, when rotating screw thread holder, suspension mechanism can bear the weight of end cover self by connecting axle, simultaneously, elastic mechanism makes screw thread holder produce with seal receptacle to be separated, such structure can make screw thread holder carry out in the process of threaded engagement in rotation, the friction between screw thread holder and high-pressure bottle and seal receptacle can be reduced as far as possible, only need less torsion just can realize rotation; The setting of elastic mechanism simultaneously, make end cover in the process of movement, produced by the rotation of screw thread holder and move axially thus drive seal receptacle to carry out axial movement, in the process driven, screw thread holder produces flexible driving force to seal receptacle, elastic mechanism now can slow down the motional inertia in screw thread holder moving process, has higher stability, and equipment can not produce larger running load.
The present invention is set to further, and described suspension mechanism is be connected to the oil cylinder of connecting axle upper end or cylinder or balancing weight.
By said structure, oil cylinder or cylinder are connected to end cover by connecting axle, make end cover be in equilibrant force state.
The present invention is set to further, and described elastic mechanism is spring, and the both ends of spring are butted on screw thread holder and seal receptacle respectively, and described spring and screw thread holder are or/and be provided with plane bearing between seal receptacle.
By said structure, the setting of spring can make to form certain Separation between screw thread holder and seal receptacle, the setting of plane bearing, can reduce screw thread holder relative to the frictional force in seal receptacle rotation process.
The present invention is set to further, described screw thread holder is arranged the fixed cover being butted on spring corresponding end.
By said structure, one end of spring is butted on seal receptacle, and the other end is butted on fixed cover.
The present invention is set to further, arranges linear bearing between described connecting axle and screw thread holder.
By said structure, can facilitate connecting axle and seal receptacle relative to the moving axially of screw thread holder.
