Clamping units of hair plucking head assembly of hair plucker

Clamping units of a hair plucking head assembly of a hair plucker. A torque transmission apparatus is disposed between the clamping units. Each clamping unit comprises a clamping piece seat. The clamping piece seat is provided with a central clamping groove. A metal clamping piece (1) is inserted into the central clamping groove in an inclined manner. Two ends of the metal clamping piece (1) are respectively located at two sides of the clamping piece seat. Taking the center of the clamping piece seat as the center of a circle, a boss (4) is disposed at a first side of the clamping piece seat 60-degree away from the metal clamping piece (1), and the boss (4) is corresponding to one end of the metal clamping piece (1) of an adjacent clamping unit. A small protrusive block (6) is disposed 180-degree away from the boss (4), and the small protrusive block (6) is corresponding to the other end of the metal clamping piece (1) of the adjacent clamping unit. The boss (4) and the small protrusive block (6) disposed at the other side of the clamping piece seat are 60-degree away from the boss (4) and the small protrusive block (6) disposed at the first side of the clamping piece seat. At least three clamping units match with each other, and can form a hair plucking head assembly of the hair plucker, with an angular difference of 60 degrees. The metal clamping piece (1) of a middle clamping unit is propped by the small protrusive block (6) of the clamping unit at one side, and is close attached to and pressed against the boss (4) of the clamping unit at the other side.
