The connecting plate 50 is pressed towards the direction of the first strap fixing bolt 6 by the hand, the third pawl 5 is separated from contact with the third ratchet wheel 4, and the third strap 20 can be pulled at the moment, and the pulled-out using length is determined according to actual needs. In use, such as the tensioner 200 is used on a truck, the third strap 20 is pulled out of the shaft 2 to a desired length, the third spiral spring 18 begins to wind up and accumulate elastic potential energy, and the third pawl 5 is then abutted against the third ratchet wheel 4. The first hook 27 and the third hook 21 are hooked on two sides of the boxcar, then the hexagonal hole 45 on the ratchet wrench 43 is sleeved on the hexagonal head 44 of the rotating shaft 2, the second handle 46 is pulled to enable the hexagonal head 44 to rotate and drive the rotating shaft 2 to rotate, and the third binding belt 20 is wound on the rotating shaft 2 again until the articles in the boxcar are tightened all the time, so that the articles in the boxcar are also tightly bound. If the binding is to be released, the connecting plate 50 is pressed by hand towards the direction of the first binding band fixing bolt 6, the third pawl 5 is separated from contact with the third ratchet wheel 4, and the third spiral spring 18 rapidly drives the rotating shaft 2 to rotate reversely due to the accumulation of enough elastic potential energy, so that the third binding band 20 is rewound on the rotating shaft 2 and wound up.
Example 5
As shown in fig. 20, the strap on tensioner 200 also includes a cord 56.
