Embodiment

The utility model is further described with reference to Fig. 1 to 5.

The utility model adopts the following technical scheme that：A kind of expansion nut, including cylinder A1 and be located under cylinder A1 Cylinder B2 on end face；The upper surface of the cylinder A1 is provided with how lateral opening 11, and screwed hole is provided with the cylinder A1 12；The screwed hole 12 and how lateral opening 11 insertions；The outer surface of the cylinder B2 is provided with screw thread 21.

Preferably, the cylinder A1 with cylinder B2 connected mode can be fixedly connected, be threadedly coupled, grafting or The forms such as person's welding.

Preferably, the outer surface of the cylinder A1 is provided with flange 13.

Preferably, the lower surface of the cylinder A1 is provided with retaining ratchet 14.

Preferably, the cylinder B2 is provided with tapered cup nut 3.
