Rotation stopping tool for installation of connector of glass fiber reinforced plastic membrane shell

The utility model relates to a glass fiber reinforced plastic membrane shell connector installation rotation stopping tool which comprises a base abutting against the inner wall of a glass fiber reinforced plastic membrane shell, a stand column is arranged on the back face of the base, and an external thread and a guide pin are sequentially arranged on the side, away from the base, of the stand column. The ejector block is assembled with the guide pin in a sleeving manner and is propped against the glass fiber reinforced plastic membrane shell interface part; and the nut is rotationally assembled on the external thread and used for being connected with the ejection block, the nut can rotate to one side of the ejection block from the external thread, and after the nut rotates to a preset position, the nut can be limited by the external thread to abut against the ejection block to lock the glass fiber reinforced plastic membrane shell interface part. Due to the fact that the base abutting against the inner wall
