The lower end of the spiral post (2) is an eccentric cone (3). While in use, the grub screw is inserted into the hole (4) of the grub screw. Using the reason that the eccentric cone seizes the grub screw to rotate together, the utility model makes the grub screw conveniently mounted and dismounted, and the work efficiency is enhanced.
