When the push shear blade 71 and the outer blade 72 are assembled, the push shear blade 71 and the outer blade 72 can be assembled and held as a whole without fastening screws or the like, and the assembly between the push shear blade 71 and the outer blade 72 is facilitated.

The operating member 75 is provided with a limit projection 751; the clipper carrier 73 is provided with a limiting groove 731, and the limiting projection 751 is inserted into the limiting groove 731. When the limiting protrusion 751 abuts against the top end inner wall of the limiting groove 731, the position corresponds to the position where the clipper connecting piece 74 rises when the clipper carrier 73 is rotated to be opened; when the limiting protrusion 751 abuts against the inner wall of the bottom end of the limiting groove 731, the position corresponds to the position where the clipper connecting piece 74 descends when the clipper carrier 73 is rotated to be closed. The position of the outer cutter 72 of the hair clipper, which is opened and closed, can be ensured to be stable.

The clipper attachment 74 is provided with a latch slot 742 and the clipper carrier 73 is provided with a latch 732; the inner wall of the gear engaging groove 742 has elasticity; when the limiting protrusion 751 abuts against the inner wall of the bottom end of the limiting groove 731, the gear engaging block 732 engages with the gear engaging groove 742. It takes an increased force to move the clipper attachment 74 upward, so that it is possible to secure the stability of the rotatably closed state of the clipper outer cutter 72 and prevent the clipper outer cutter 72 from being automatically opened by vibration when carrying the shaver.

As used in the present invention, the term: first, second, etc. do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

As used in the present invention, the term: one, etc. do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.

As in the present invention, the term indicating orientation or position is used: top, bottom, side, longitudinal, lateral, middle, center, outer, inner, horizontal, vertical, left, right, above, below, and the like are intended to reflect relative positions, not absolute positions.

The term as used in the present invention: approximate, whole, approximate, close, etc., are words of definition that specify the presence of stated features but allow for certain deviations. The amount of tolerance for a certain deviation may vary depending on the particular context; for example, the specific context in which deviations from size may be relied upon includes, but is not limited to, national standards for dimensional tolerances.
