It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1-4, the umbrella-shaped split nut disclosed by the utility model comprises a nut body 1, an elongated arm 2 and a connecting cylinder 3; a plurality of convex arms 11 are arranged around the nut body 1; the outer wall of the connecting cylinder 3 is connected into the nut body 1 through a first thread; the lengthening arm 2 is rotatably connected to a convex arm 11 of the nut body 1; wherein a second thread 32 is provided in the connecting cylinder 3, opposite to the first thread 31. It should be understood that the umbrella-shaped split nut can be designed to be smaller according to the needs, so that the umbrella-shaped split nut is suitable for fixing the template in construction places with large fixing difficulty or narrow space, such as expansion joints, post-cast strips and the like. Wherein, because the extension arm 2 can extend 180 degrees along the convex arm 11, not only can pass through a smaller construction space, but also can be well fixed.

Referring to fig. 1-3, in this embodiment, the length of the elongated arm 2 is greater than the length of the protruding arm 11. In the present embodiment, the elongated arm 2 preferably has a thickness corresponding to the thickness of the protruding arm 11.
