An adjusting frame 5 is rotatably installed on the side surface of the side frame 4. A through-type mounting groove 6 is opened on the top side wall of the adjusting frame 5. A sliding groove 8 is opened on the inner wall of the support plate 7. A slot 9 is opened at the connection between the support plate 7 and the adjusting frame 5. A supporting sliding shaft 12 is fixedly installed on the two side end faces of the tension wheel body 11. A spring 13 is sleeved on the outer surface of the supporting sliding shaft 12. A spring 13 is fixedly installed on the outer surface of the sliding sleeve 14. There are two symmetrically spaced limiting rods 16. The support plate 7 is fixedly installed on the top side face near the adjusting frame 5. The tension wheel body 11 is sleeved in the mounting groove 6 through the supporting sliding shaft 12. One end of the spring 13 abuts against the side wall of the adjusting frame 5, and the other end of the spring 13 abuts against the inner end face of the sliding sleeve 14. The sliding sleeve 14 slides on the inner surface of the sliding groove 8 through the limiting rods 16. A through-hole 15 is opened on the inner surface of the sliding sleeve 14.
