Description
Technical Field

Background
In most of the existing hair trimmers such as shavers, electric hair clippers, and body hair care products, as shown in fig. 9 and 10, a motor 21 drives a rocker arm 23 to swing left and right relative to a rocker shaft 24 through an eccentric wheel 22, and the rocker arm 24 drives a movable blade 27 to swing left and right through a movable blade driving block 26. Normally, the rocker shaft hole 25 and the rocker shaft 24 must have a certain fit clearance, because too small a fit clearance between them will result in increased friction, and thus increased output load of the motor will result in higher operating current, and thus reduced battery discharge time, and the temperature rise of the cutter head/motor will be higher than the safety standard range. However, the fitting clearance required between the rocker shaft hole 25 and the outer circumference of the rocker shaft 24 causes a large noise due to rocking collision and a small rocking stroke of the movable blade 27 during the movement of the rocker arm, and the output energy of the motor 21 is lost, thereby deteriorating the shearing performance of the side teeth on both sides of the stationary blade. The moving blade swings left and right in a stroke depending on the eccentric amount of a protruding shaft on the eccentric wheel 22 and the center of the eccentric wheel main body, if the eccentric amount is 1.3mm, namely the total swing stroke of the moving blade is 2 times of the eccentric amount 1.3 and is 2.6mm, the matching clearance between the rocker shaft hole 25 and the outer circle of the rocker shaft is too large, so that the moving blade swings during movement, and the total stroke of the moving blade during shearing is reduced due to the clearance, so that the shearing capacity of the fixed blade side teeth is poor.
