Furthermore, when the cable passes through the round sleeve 141, the matching block 142 will squeeze the air bag 143, so that the air bag 143 is deformed, so that the matching arc strip 147 makes the slide bar 144 slide inside the block 142, and the matching ring block 145 makes the clamping spring 146 compress and deform, so as to better adapt to cables with different outer diameters, so that there is no gap between the cable and the round sleeve 141, thereby preventing external impurities and dust from entering the box body 1, and then can further protect the device body.
