The hook body and the rod body are made of stainless steel materials; the length of the rod body is 6mm, and the outer diameter of the hook body is 4mm, so that the hook body is suitable for being placed in the oral cavity of a human body as much as possible.
The bonding pedestal is cylindrical, the outer diameter is 3mm, and the height is 1mm.
The connecting seat head and the bidirectional traction hook connector are in a circular cylinder shape with internal threads, the internal diameter and the external diameter are consistent, and the connecting seat head and the bidirectional traction hook connector are connected in series and fixed through screws to form a cylinder shape. The outer diameter of the connecting seat head and the two-way traction hook connector is 2mm, and the height is 1.5mm, so that the connecting seat head and the two-way traction hook connector are suitable for being placed in the oral cavity of a human body as much as possible.
The foregoing examples are illustrative of the present utility model and are not intended to be limiting, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principles of the utility model are intended to be equivalent and are within the scope of the present utility model.
