The two groups of first bolts 205 respectively penetrate the inner cavity of the corresponding side square hole 204 and extend to the outside of the support plate 101. The two groups of first bolts 205 located at the bottom respectively penetrate the surface of the corresponding side bottom plate 100 and extend to the outside of the bottom plate 100. Through the setting of the cloth tensioning assembly, the cloth is placed on the top surface of the bottom plate 100, and then the threaded column 203 is rotated to push the U-shaped block 200 located above downward to press the cloth, and then the first bolt 205 located at the bottom is rotated to move the two groups of pressing blocks 201 outward at the same time to tighten the cloth at the bottom, and then the two groups of first bolts 205 located at the top are rotated, and the two groups of pressing blocks 201 tighten the cloth at the top, thereby tightening the upper and lower sides of the cloth, so that the deformation degree of the cloth is consistent, and thus the cloth cut has a better effect.
