A slider 11 is screwed on the outside of the screw rod 10, and a connecting rod 12 is rotatably installed on the lower surface of the slider 11. A buffer rod 13 is rotatably installed on the lower end of the connecting rod 12, and the lower end of the buffer rod 13 is fixed to the upper part of the lifting tool.

[0024] The lifting tool is composed of a lifting crossbar 6, an upper knife seat 7 and an upper blade 8. The two ends of the lifting crossbar 6 are slidably connected to the vertical tracks 14 on the support rod 3 and the connecting rod 5 respectively. The middle part of the upper surface of the lifting crossbar 6 is connected to the lower end of the buffer rod 13. The upper knife seat 7 is welded to the lower surface of the lifting crossbar 6, and the upper blade 8 is fixed to the lower part of the upper knife seat 7 by bolts. The fixed tool is composed of a fixed crossbar 2, a lower knife seat 18 and a lower blade 19.
