The driving assembly includes a plurality of connecting strips 11 and a plurality of push rods 12. The four sides of the bottom of the conical block 13 are fixed with a plurality of push rods 12 by bolts. The circumferential outer walls of the plurality of rotating shafts 14 are fixed with connecting strips 11 by bolts. A reserved opening is provided on the support seat 10, and the connecting strip 11 passes through the reserved opening, and each push rod 12 is in contact with the corresponding connecting strip 11.
