A horizontal plate 4 is installed at the rear end of the frame 1. Several sliding rods 5 are slidably connected inside the horizontal plate 4, and each sliding rod 5 corresponds to one of the annular guide grooves 3. Several sliding holes 15 are formed inside the horizontal plate 4, and the horizontal plate 4 is slidably connected to the sliding rods 5 through the sliding holes 15. A pressing block 6 is installed at the upper end of the sliding rod 5, and a U-shaped block 8 is installed at the lower end of the sliding rod 5. A tensioning wheel 9 is rotatably connected inside the U-shaped block 8, and the tensioning wheel 9 corresponds to one of the annular guide grooves 3. A scale line 7 is provided at the rear end of the sliding rod 5. A sliding groove 10 is formed at the right end of the sliding rod 5, and a fixing rod 11 is installed inside the sliding groove 10. The outer surface of the fixed rod 11 is slidably connected to the fixed block 12, and the fixed block 12 is fixedly connected to the inner wall of the sliding hole 15. The outer surface of the fixed rod 11 is fitted with a spring 13, and the spring 13 is located at the upper end of the fixed block 12. Several positioning grooves 14 are opened at the left end of the sliding rod 5. The positioning mechanism 16 is set inside the horizontal plate 4 corresponding to the position of the sliding rod 5. The positioning mechanism 16 includes a cavity 17 and a pull block 18. The cavity 17 is located on the left side of the sliding hole 15. The pull block 18 is slidably connected inside the cavity 17. Two positioning blocks 19 are installed on the right end of the pull block 18, and the positioning blocks 19 pass through the position of the left end of the sliding hole 15 corresponding to the positioning groove 14.

[0023] The working principle of this utility model is as follows: When it is necessary to adjust the position of the corresponding tension wheel 9, the sliding rod 5 is pushed down by the pressing block 6. The sliding rod 5 drives the tension wheel 9 down through the U-shaped block 8, thereby adjusting the tension. The adjustment position of the tension wheel 9 can be quickly grasped through the scale line 7. When the sliding rod 5 descends, the sliding rod 5 drives the fixing rod 11 down, causing the slide groove 10 to descend and compress the spring 13.
