Several adjusting bolts 405 are threaded through the slide 404, and the lower ends of the several adjusting bolts 405 contact the upper surface of the support arm 4 and the upper surface of the slide 404 respectively.

[0041] First, based on the combined use of internal and external threads, the position adjustment of the cutting cylinder 5 and the adjusting cylinder 2 is guaranteed to be reliable. And with the combined limiting use of the turntable 201, the rotation of the rotating ring 501 is guaranteed to be reliable and the movement distance of the rotating cylinder 3 is controllable.

[0042] By rotating the turntable 201, adjust the position of the adjusting cylinder 2 on the bracket 1. Then slide the rotating cylinder 3 to adjust its position outside the adjusting cylinder 2. After the position is stable, rotate the fastening arm 302 to simultaneously insert the insertion rod 304 into the positioning hole 202 and the insertion hole 301, and simultaneously lock the fastening arm 302 into the positioning bolt 305. Then use multiple fastening arms 302 and insertion rods 304 to stably fix the rotating cylinder 3 outside the adjusting cylinder 2, and then adjust the tightness of the adjusting bolt 405. With the sliding of the slide 401 and the slide 404, the position between the two placement arms 406 is adjusted, and then the adjusting bolt 405 is tightened to make the slide 404, the positioning frame 403, and the support arm 4 in a tight state, ensuring the tightness of the placement arm 406 in use.
