[0022] Specific use time: taper head 202 and support plate 201 can realize the support structure effect of the material to be processed.

[0023] In the embodiment: workpiece clamping structure 9 includes clamping block 901, the bottom of clamping block 901 is attached to the top of upper frame 4, and the outer wall of the side of two groups of clamping blocks 901 is fixedly installed with supporting plate 902, the number of supporting plate 902 is several groups and is equidistantly distributed on clamping block 901, and the upper surface of supporting plate 902 is horizontal with the upper surface of taper head 202.

[0024] Specific use time: clamping block 901 can clamp the material to be processed, and supporting plate 902 can play the role of lifting the workpiece to be processed when taper head 202 is uneven, to prevent the inclination of the workpiece in the processing process.

[0025] In the embodiment: the end of clamping block 901 close to slide 7 is fixedly installed with sliding ring 903, sliding ring 903 is sleeved on the outer wall of slide 7, and the inner diameter size of sliding ring 903 is slightly larger than the outer diameter size of slide 7.

[0026] Specific use time: sliding ring 903 plays the limiting role of clamping block 901 and supporting plate 902 in the left and right moving process, to prevent the self-rotation phenomenon of clamping block 901 and supporting plate 902 when following the rotation of screw rod 8.
