Since the widths of the first and second cutters 101 and 201 are just consistent with the widths of the docked dental sockets 8, the first and second cutters 101 and 201 cannot slide out of the cutter lifting grooves 801 of the dental sockets 8 due to the limitation of the walls of the screw holes 9 in the screw holes 9, but when one ends of the cutter lifting grooves 801 of the dental sockets 8 are outside the screw holes 9, the first and second cutters 101 and 201 are inserted and easily slide out of the dental sockets 8. Therefore, in this embodiment, the third knife-lifting device 3 is specially configured, the width of the third knife-lifting device 3 is designed to be far greater than the outer diameter of the tooth socket 8, so that the third knife-lifting device is not easy to slide out of the knife-lifting groove 801, and meanwhile, the knife edge of the third knife-lifting device 3 is set to be an arc-shaped knife edge 301, and when in application, a part of the arc-shaped knife edge 301 is sunk into the inner hole of the tooth socket 8, so that the third knife-lifting device is not easy to slide. Thus, the problem that the installation of the dental floss 8 into the hole cannot be successfully completed because the dental floss 8 easily slides out from the outside of the screw hole 9 to the initial stage of screwing in the screw hole 9 is solved.

The above embodiments are only for the purpose of more clearly describing the present utility model and should not be construed as limiting the scope of the present utility model, and any equivalent modifications should be construed as falling within the scope of the present utility model.
