The end of the electric push rod 6 is fixed at the top of the side end of the other support plate 3, and the output shaft of the electric push rod 6 passes through the support plate 3;

[0023] The centering and orienting component includes a first thimble 7 and a second thimble 8. The first thimble 7 is fixed at the end of the rotating headstock 5, that is, the first thimble 7 can rotate synchronously with the rotating headstock 5. The second thimble 8 is rotatably connected to the output shaft of the electric push rod 6 through a bearing seat 9. That is, when the electric push rod 6 operates, it can drive the second thimble 9 to move horizontally back and forth. And under the action of the bearing seat 9, the second thimble 8 can rotate freely relative to the output shaft of the electric push rod 6. The centering and orienting component further includes a centering fixed seat 10. A fixed pressure plate 12 is fixed at the edge of the centering fixed seat 10 through a first fixing screw 11. The end of the gear 2 is located within the fixed pressure plate 12.
