The paddle 300 is provided to facilitate the staff to press down the insertion rod 240, thereby improving the ease of installation work.

[0031] Working principle and usage process of the utility model: When this device is put into actual use, the left steel frame 110 and the right steel frame 120 are successively embedded inside the outer rotor, and then an external tool is used to squeeze the dial 300, so that the insertion rod 240 retracts into the inside of the hollow tube 220. Here, the spring 230 is stressed and contracts to provide a moving space for the insertion rod 240. Then, the connecting piece 210 is placed between the left steel frame 110 and the right steel frame 120, and then the position of the connecting piece 210 is adjusted so that multiple insertion rods 240 are inserted into the left steel frame 110 and the right steel frame 120. The structure is simple and the installation is convenient.
