The side of the crossbar 13 facing the cutting machine table 100 has a mounting base 18, and the mounting base 18 has a through hole 181.

[0027] A tension rod support frame 2 is installed on the side of the support frame 1 away from the cutting blade support frame 101. The tension rod support frame 2 includes a circular vertical tube 21 and a circular horizontal tube 22. The bottom of the circular vertical tube 21 is inserted into the circular hole 181 from bottom to top. A screw 182 is screwed to one side of the mounting base 18. The tail end of the screw 182 abuts against the outer wall of the circular vertical tube 21 to lock the circular vertical tube 21 in the circular hole 181. Tightening the screw 182 locks the circular vertical tube 21 in the circular hole 181. Loosening the screw 182 allows the circular vertical tube to be adjusted in the circular hole to adjust the installation height. The circular horizontal tube 22 is welded to the top of the circular vertical tube 21 and is perpendicular to the circular vertical tube 21. A screw 23 is screwed onto the circular horizontal tube 22.

[0028] A fixed tension rod 3 is installed on the tension rod support frame 2. One end of the fixed tension rod 3 is inserted into the circular horizontal tube 22.
