[0020] like Figures 1 to 5 When the tooth 1 is fixed with the tooth 1, the tooth 1 is fixed with the connecting layer 2, and the connecting layer 2 is fixed with the base 3. Two elastic sheets 8 are fixedly installed in the middle of the top surface of the base 3. The outer end of the top surface of the base 3 is fixedly installed with a vertical plate 4. An upper clamping block 16 and a lower clamping block 14 are slidably installed between the two vertical plates 4. A steel wire 7 is installed between the upper clamping block 16 and the lower clamping block 14. The two vertical plates 4 are fixedly installed with a supporting plate 5 on the top. A bolt 6 is installed in the middle of the support plate 5. The bottom of the bolt 6 is tightened to the upper clamping block 16. The top plate 20 is fixedly installed on the two outer sides of the base 3. The bolt 6 provided in the utility model is adjusted so that the upper clamping block 16 and the lower clamping block 14 can slide up and down between the two vertical plates 4 so that the steel wire 7 can move up and down. The elastic sheet 8 presses the lower clamping block 14 tightly so that the steel wire 7 is fixed after moving. The top plate 20 can support the two ends of the steel wire 7, and the tightness adjustment of the steel wire 7 can be completed by simple operation.

[0021] A card channel 9 is provided on the inner side of the vertical plate 4 , and an entrance 10 is provided on the outer end of the card channel 9 . The card channel 9 is used to limit the circumferential position of the upper clamping block 16 so that the upper clamping block 16 can only move up and down. The entrance 10 is used for the entry of the slide rod 15 .

[0022] The two outer ends of the upper clamping block 16 are respectively provided with upper fixing blocks 11, and the two outer ends of the lower clamping block 14 are respectively provided with lower fixing blocks 12. The outer ends of the upper fixing block 11 and the lower fixing block 12 are fixed to the upper clamping block 16 and the lower clamping block 14 to fix the steel wire.
