Description

technical field [0001] A fastening device belongs to the field of machinery and new technology. Background technique [0002] The known bolts are cumbersome to use and take a long time to tighten or loosen. Contents of the invention [0003] A fastening device is provided here, which can be unscrewed or tightened quickly and is not afraid of rust. It will not rust even if it gets rusty, and it can be unscrewed quickly. [0004] The invention is as follows: the cylindrical toothed bar (1) has a round head (2) at one end, the cylindrical toothed bar (1) is inside the bracket plate (5), the bracket plate (5) is concave in shape, and the bracket Both sides of the plate support the fork (3), the fork is covered with a tooth of the rib rack (1), and the end of the fork (3) has a wheel disc (4). In use, the ribbed rack passes through the object to be fastened and penetrates into the bracket plate. At this time, pinch the wheel disc of the fork and turn the fork to cover the t...
