[0023] A cylindrical gear 16 and a main shaft transmission gear 23 meshing with the cylindrical gear 16 are arranged below the workbench 14. The brake unit 15 includes a slide 17, a floating brake seat 18 that can move laterally on the slide 17, a brake tooth 19 arranged on the floating brake seat 18, and a clutch brake assembly 20 arranged in the floating brake seat 18 for stopping the rotation of the brake tooth 19, and an adjustable pressure cylinder 21 arranged on the slide 17 for pushing the floating brake seat 18, and an ejection type floating support cylinder 22 arranged on the slide 17 for fixing the floating brake seat 18, and the ejection type floating support cylinder 22 is located above the adjustable pressure cylinder 21.
