As an improvement of the utility model, the transition is made between the middle section of the rotating shaft and the two ends through an inclined plane. The transition of the nut between the thread section and the installation section is smoother due to the inclined surface transition structure.

As the utility model discloses an improve, be located the cover and be equipped with the innerspring on the erection site between inner bearing frame and the screw thread section, the one end of innerspring is contradicted on the inner bearing frame, the one end that the innerspring is close to the screw thread section is fixed with interior baffle. The design of the inner spring ensures that the nut can be smoothly meshed with the thread section again when the rotating shaft rotates reversely. The design of the inner baffle further ensures the smoothness of the re-engagement of the nut and the thread section.

As the utility model discloses an improve, be located the cover and be equipped with outer spring on the erection section between outer bearing frame and the screw thread section, the one end of outer spring is contradicted on the shell inner wall, the one end that outer spring is close to the screw thread section is fixed with outer baffle. The design of the outer spring ensures that the nut can be smoothly meshed with the thread section again when the rotating shaft rotates reversely. The design of the outer baffle further ensures the smoothness of the re-engagement of the nut and the threaded section.
