For this reason, we proposed a horizontal tensioner, which forms a tension adjustment mechanism through a fixed block, an adjusting nut, a screw and a fastening bolt. The tension adjustment mechanism is used to adjust the rear end starting position of the spring according to the working state of the tensioner to complete the tension adjustment switching.
