Description
Technical Field
The invention relates to a cloth device, in particular to a tension adjusting device for cloth.
Background
In addition to the basic forms of the various screw connections, so-called tensionable screw connections have been used for decades. In particular, screw tensioners are used in steel construction and in various engine design applications. The screw tensioners generally all operate according to the same well known principles based on the torque-free tensioning method. In order to apply tension to the screw or bolt, the first end of the screw is typically connected to the first component via a threaded arrangement. The second end then extends through the second component. A nut may then be placed on the screw to secure the first and second components. Tension may then be applied to the screw. The nut may then be further tightened to maintain the tension applied to the screw. After the nut is tightened, the screw tensioner may fall off the screw.
Disclosure of Invention
Aiming at the problems, the invention provides a tension adjusting device which is compact in structure and convenient and fast to operate.
