In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0033] Referring to Figures 1 to 3 The utility model provides a kind of split nut, including big nut 1, connecting shaft 2 and super nut 3, big nut 1 includes first pair of half nuts 11 and second pair of half nuts 12, first pair of half nuts 11 and second pair of half nuts 12 shape are compatible;Connecting shaft 2 passes through first pair of half nuts 11 and second pair of half nuts 12 respectively, for first pair of half nuts 11 and second pair of half nuts 12 are connected with cooperation;Super nut 3 is set on connecting shaft 2 and is connected with connecting shaft 2 by screw thread, for limiting the relative position of connecting shaft 2 and big nut 1, super nut 3 is connected by screw thread with multiple push bolts 31.

[0034] In the embodiment, the large nut 1 and the super nut 3 are both cylindrical nuts, the inner walls of the first pair of half nuts 11 and the second pair of half nuts 12 are provided with threads for threadedly connecting with the column 7, two connecting shafts 2 are symmetrically arranged on one large nut 1, the length direction of the connecting shaft 2 is arranged at an angle with the central axis of the large nut 1, the super nut 3 is coaxially arranged with the connecting shaft 2, and a plurality of pushing bolts 31 are arranged around the connecting shaft 2, and the length direction of the pushing bolt 31 is parallel to the length direction of the connecting shaft 2.

[0035] Thus, since the pushing bolt 31 is not coaxial with the large nut 1, when the large nut 1 is connected with the column 7 and subjected to vibration from the whole machine 6, the large nut 1 is not prone to circumferential rotation under the restriction of the super nut 3 and the pushing bolt 31, thereby avoiding loosening of the large nut 1 on the column 7, improving the pre-tightening effect of the split nut, and saving installation space; since the pushing bolt 31 has a small diameter and requires a small torque, the large stress pre-tightening can be realized by using an ordinary wrench, so that the split nut has high overall structural strength, is convenient to install and disassemble, and has high reliability and safety.

[0038] Thus, when an external torque acts on the super nut 3, the connecting shaft 2 will be extruded and deformed, and relative movement will occur between the super nut 3 and the pushing bolt 31 under the deformation, which can increase the friction between the pushing bolt 31 and the super nut 3, between the super nut 3 and the connecting shaft 2, and between the connecting shaft 2 and the large nut 1, thereby achieving the locking effect and improving the reliability and stability of the split nut.

[0039] It can be understood that the angle between the length direction of the connecting shaft 2 and the central axis of the large nut 1 can also be adjusted according to actual design needs. In the embodiment, the connecting shaft 2 is arranged perpendicular to the central axis of the large nut 1 for the convenience of assembly and locking.
