Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
1 it is Jie's bar in attached drawing, 2 be primary nut, 3 be cylinder core, 4 be cylinder sleeve, 5 be locking nut, 6 be big nut, 7 is cross
Head, 8 be driving hole, 9 be action pane.
Specific embodiment
The utility model includes the big nut with the primary nut 2 of 1 external screw thread of Jie's bar cooperation and with the cooperation of 7 external screw thread of crosshead
6, it is characterised in that: be provided with cylinder sleeve 4 between big nut 6 and primary nut 2, be provided with cylinder core 3 in cylinder sleeve 4, the end face of cylinder core 3 with
The primary nut 2 cooperates, and the end face of cylinder sleeve 4 and the big nut 6 cooperate；It is provided with oil filler point on cylinder sleeve 4, it is corresponding on cylinder sleeve 4
Locking nut 5 on Jie's Yu bar 1 is provided with action pane 9.
As a kind of preferred embodiment of the utility model, the big nut 6, primary nut 2 and 5 outer surface of locking nut are arranged
Cloth is provided with multiple driving holes 8.
3 surface of cylinder core is provided with the positioning spigot cooperated with primary nut 2.
When the utility model is used, Jie's bar 1 and crosshead 7 are connected and screws locking nut 5；Then, by big nut 6
It is fixed on the external screw thread of crosshead 7, cylinder sleeve 4 is mounted on outside Jie's bar 1,4 end face of cylinder sleeve is contacted with 6 surface of big nut；By cylinder
Core 3 is installed in cylinder sleeve 4；Primary nut 2 is fixed on Jie's bar 1 again；The cooperation of the positioning spigot of primary nut 2 and cylinder core 3；Pass through note
Oilhole is separated to injection pressure oil between cylinder sleeve 4 and cylinder core 3, cylinder sleeve 4 and cylinder core 3, is stretched through 2 pairs of Jie's bars 1 of primary nut；
After 1 length of Jie's bar is stretched, can at action pane 9, to 5 further progress of locking nut pre-tighten, guarantee locking nut 5 can
By installation.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
