Screwing the lever 91 can drive the elastic end head 92 to move up and down, and move away from or close to the bearing and dragging end surface of the straight line rail b62 which is arranged oppositely below.
When the rotating rod 91 is screwed to move downwards relative to the stud 71, the elastic end 92 can press on the end face of the linear rail b62 arranged at the lower side, and conversely, when the rotating rod 91 is screwed to move upwards relative to the stud 71, the elastic end 92 can be separated from the end face of the linear rail b62 arranged at the lower side.
In order to prevent the elastic end 92 from rotating synchronously with the rotating rod 91 when the rotating rod is rotated, the operation is more labor-saving. In some embodiments, the lower end of the rotating rod 91 is provided with a sleeve b, and the lower port of the sleeve b is provided with an annular flange extending radially inward. The upper end of the elastic end head 92 extends into the sleeve b through the inner ring of the annular flange and is connected with a thread sleeve a.
In some embodiments, the blocking assembly is disposed on the right side wall plate of the U-shaped frame and is oppositely arranged below the tension assembly.
Referring to fig. 1, the blocking assembly includes a functional portion and a driving unit. The functional part comprises a resistance frame 81 and an arched pad 82 fixedly arranged at one end of the resistance frame 81, wherein the arched pad 82 is arranged in the U-shaped frame 2, and the notch of the arched pad 82 is opposite to the notch of the pressure applying belt 4. The resistance frame 81 is matched with the right side wall plate of the U-shaped frame 2 through a linear track structure extending along the left-right direction, the other end of the resistance frame 81 is matched with the driving unit 83, and the driving unit 83 can drive the resistance frame 81 to slide along the left-right direction relative to the right side wall plate of the U-shaped frame 2. That is, the slide base 7 in fig. 2 is rigidly integrated with the right side wall plate of the U-shaped frame 2. The arched pad 82 can only change its position by the driving unit 83 driving the resistance frame 81 to move left and right.
