Fixed connection; through the above structure, when the stepper motor 20 drives the turntable 12 to deflect ninety degrees at a fixed frequency, under the action of the tensioning spring 23, the end of the arc head cavity block 22 can be adapted and connected with the hemispherical slot 24, thereby fixing the turntable 12; at the same time, when the stepper motor 20 runs again, the torsional force generated by the turntable 12 can retract the arc head cavity block 22 through the hemispherical slot 24, and when the adjacent hemispherical slot 24 is aligned with the arc head cavity block 22 again, the arc head cavity block 22 can be clamped into the hemispherical slot 24 again.

[0035] Furthermore, a column 17 is fixedly installed between the top of the fixed block 16 and the side frame 2, and a V-shaped support frame 4 is fixedly installed between one side of the column 17 and the side frame 2, a limiting groove 18 is provided on the other side of the column 17, and a limiting slide bar 19 that slides with the limiting groove 18 is fixedly installed on one side of the connecting plate 901; the V-shaped support frame 4 and the column 17 can improve the structural stability of the device; at the same time, the limiting slide bar 19 and the limiting groove 18 cooperate with each other to improve the stability of the up and down movement of the connecting plate 901 and ensure the accuracy of the punching operation.

[0036] Furthermore, a plurality of equidistantly distributed reinforcing ribs 3 are fixedly connected between the side stand 2 and the frame seat 1; this arrangement can improve the structural stability of the side stand 2.

When the cutting tube 11 abuts against the upper, the end of the cutting tube 11 can complete the cutting and punching of the upper. The round chips generated by the punching will be retained in the lumen of the cutting tube 11, so they will not fall onto the upper. When cleaning is required later, the stepper motor 20 drives the turntable 12 to deflect 90 degrees again.
