[0025] Specifically, Figure 1 As shown, the L-shaped plate 2 is symmetrically distributed on the outside of the nut body 1, the clamping cover 5 is symmetrically distributed on the top of the nut body 1 through the moving rod 4, and the interior of the clamping cover 5 is hollowed out, the end of the compression spring 6 away from the clamping cover 5 is fixedly connected to the outside of the movable tube 3, the connecting plate 7 is located above the movable tube 3, the pulling rod 9 crosses the inside of the conduit 8, and the limiting rod 10 is movably connected to the bottom of the connecting plate 7 through the pulling rod 9.
[0026] In this embodiment: by setting up a nut body 1, the nut body 1 is first connected to the screw rod. When the connection is completed, the pull rod 9 is moved upward inside the conduit 8, so that the pull rod 9 drives the limit rod 10 to move upward, and the limit rod 10 is away from the outside of the clamping cover 5. At this time, the clamping cover 5 is moved by the moving rod 4 under the action of the compression spring 6, so that the two clamping covers 5 are close to the screw rod inside the nut body 1, thereby clamping the screw rod inside the nut body 1, thereby preventing the nut body 1 from loosening.
[0027] Example 2 Please refer to Figure 1 , Figure 2 and Figure 4 The difference between this embodiment and embodiment 1 is that: the outer side of the nut body 1 is fixedly connected to the operating box 11, the inside of the operating box 11 is fixedly connected to the elastic oil bag 12, the top of the operating box 11 is clamped with an oil inlet cover 13, the inside of the operating box 11 is movably connected to an extrusion rod 14, the outer side of the elastic oil bag 12 is fixedly connected to the oil pipe 15, the outer side of the oil pipe 15 is fixedly connected to the telescopic hose 16, and a leakage hole 17 is opened in the inner bottom wall of the clamping cover 5.
