Abstract: A hair clipper blade and a manufacture method thereof, comprising using initially a stamping equipment to stamp out a semi-processed blade having plural round through holes, and then using a grinding wheel to perform cutting operations at the front end of the round through holes in the semi-processed blade toward the round through hole direction thereby forming two corresponding edge parts such that plural tooth units can be created on the movable blade, wherein both the two sides of the front end in each tooth unit include an edge part, and a groove hole is inwardly arc-wise formed between the bottom end of each side in each tooth unit and the bottom end in the adjacent tooth unit.

Abstract: A reciprocating tapping device includes a casing, a motor, a power supply, a transmission portion and a tapping portion. The tapping portion is connected with and driven by the transmission portion. An eccentric shaft is connected with the transmission portion. The tapping portion has a reciprocating portion. The reciprocating portion is connected with two tapping bars. The bars extend out of the casing. The eccentric shaft can covert the circular motion of the motor to back-and-forth motion. Therefore, the tapping portion can move backwards and forwards and the two tapping bars can move backwards and forwards. A flat plate is disposed in the front and back of the reciprocating portion so as to pivotally hold the reciprocating portion. Therefore, the tapping portion can move backwards and forwards without any sideway motion.

Abstract: A patting device includes a case for containing other structures; a motor disposed in the case for rotation; a power source installed in the case to provide power to the motor; a transmission structure connected to an output shaft of the motor to transmit power of the motor; and a patting structure at least comprising a turntable connected to and driven by the transmission structure, wherein the turntable includes a protruding block disposed off-axis with respect to the turntable, and a ring body is disposed around the protruding block and connected with a patting bar extending out of the case. Hence, the power of the motor is transmitted through the transmission structure to the patting structure; when the turntable rotates, the off-axis placement of the protruding block drives the patting bar to move back and forth to let the patting bar pat the human body to provide health care effects.

Abstract: The invention discloses an adjustable apparatus for adjusting an upper blade position of a hair clipper to further adjust the hair cut length. The upper blade is connected to a blade spring. The blade spring is placed in a spring housing. The spring housing is connected to a pushing block. The pushing block is connected to a rotary wheel. Therefore, the position of the upper blade is adjustable by moving the rotary wheel.
