The rotating end block has a limiting tooth groove at the end away from the auxiliary end plate. The auxiliary end plate is evenly welded with stabilizing teeth on the side away from the rotating end block. A sleeve hole is provided on the top surface of the docking gasket, and matching teeth are evenly welded on one side of the docking gasket. A positioning nail body is evenly welded on the side away from the matching teeth.

[0007] As a preferred embodiment of the present invention: the main polygonal column is arranged in the shape of a polygonal column, and the movable grooves are symmetrically opened in groups of two on the side of the main polygonal column near the two ends, and the interior of the movable groove is kept in communication with the interior of the vertical slot. The plug-in end of the toggle block extends to the inner side of the vertical slot, and the extended end is fixedly connected to the side of the movable inner rod near one end.

After the limiting tooth and the limiting tooth groove are away from each other, a rotating end block rotation process can be formed. After the main polygonal column is rotated, the connecting screw forms a thread tightening effect on the mounting body. After tightening to a specified spacing, the side edges of the docking gaskets at both ends are docked and set at the side position of the object, so that multiple positioning nails on the side are inserted and set on the side of the object. The position effectively prevents the rotation of the docking gasket, and after the squeezing operation of the rotating end blocks at both ends, the auxiliary end plate is squeezed to the side of the docking gasket, so that the stabilizing teeth on the side and the matching teeth are engaged with each other, which further stabilizes the rotation between the rotating end block and the docking gasket, and after the toggle block is released, the top connection of the top spring extends the movable inner rod, so that the limiting teeth at one end and the limiting tooth grooves are engaged with each other, thereby limiting the rotation between the main polygonal column and the rotating end block. The use of multiple rotation-restricting structures makes it impossible to form a rotation operation after installation, and the cooperation of the tooth connection effectively prevents the occurrence of rotation loosening after installation.

[0024] One end of the connecting screws 7 at both ends of the main polygonal column 1 is inserted and set inside the mounting hole. After the external toggle block 3 is toggled, the movable inner rod 9 is driven to move along the inside of the vertical slot 8, so that one end squeezes the top spring 11 to contract, so that the limiting tooth 10 at one end of the movable inner rod 9 is away from the limiting tooth groove 15. After the limiting tooth 10 and the limiting tooth groove 15 are away from each other, the rotating end block 4 can be rotated. After the main polygonal column 1 is rotated, the connecting screw 7 forms a thread tightening effect between the mounting body, and after tightening to the specified spacing, the side edges of the docking gaskets 6 at both ends are docked and set on the object. The side position of the object allows multiple positioning pins 19 on the side to be inserted and set at the side position of the object, effectively preventing the rotation of the docking gasket 6. After the rotating end blocks 4 at both ends are squeezed, the auxiliary end plate 5 is squeezed toward the side of the docking gasket 6, allowing the side stabilizing teeth 16 and the matching teeth 18 to engage with each other, thereby further stabilizing the rotation between the rotating end block 4 and the docking gasket 6. After the toggle block 3 is released, the top connection of the top spring 11 causes the movable inner rod 9 to extend, allowing the limiting teeth 10 at one end to engage with the limiting tooth groove 15, thereby limiting the rotation between the main polygonal column 1 and the rotating end block 4.
