AI Technical Summary
In existing nose hair trimmers, the assembly efficiency of the movable knife and plastic parts is not high, and the overall effect is not good, which leads to unsafe and reliable use.
The plastic core is equipped with a fixed knife and a movable knife. The movable knife slides through the side hole and the knife seat, and is equipped with an elastic locking tongue and a lever to form an elastic interference structure to ensure that the engagement point between the movable knife and the plastic core is elastic and reduces the Assembly interference force and improve use safety.
In the case of high-speed rotation, the blade edge of the movable knife and the fixed knife are well fitted, reducing the probability of the blade being removed, improving the safety and reliability of the nose hair trimmer, and enhancing the overall functional perfection.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0017] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0018] Example 1
[0019] See also Figures 1 to 5As shown, a nose hair trimmer involved in this embodiment includes a plastic core member 1, on which a fixed knife 2 is coaxially arranged, the fixed knife 2 rotates relative to the plastic core member 1, the plastic core member 1 is provided with a movable knife 3 for follow-up, the fixed knife 2 is provided with a guide hole 4, the plastic core member 1 is provided with a side hole 5 extending radially, the movable knife 3 includes a knife seat 31 slidably connected in the side hole 5, and a blade 32 arranged outside the side hole 5, the movable knife 3 moves radially relative to the plastic core member 1, the knife seat 31 is provided with an elastic locking tongue 33, the hole wall of the side hole 5 is provided with a stopper 51 for blocking the elastic locking tongue and limiting the knife seat from escaping from the side hole, the movable knife 3 is provided with a shifting hole 34 arranged outside the side hole 5, and also includes an elastic shifting rod 6 with one end connected to the plastic core member 1 and the other end inserted into the shifting hole 34, the elastic force provided by the elastic shifting rod 6 causes the knife seat 31 to move axially away from the plastic core member 1.
[0020] Furthermore, the number of the movable knives 3 is two, and the interval angle between the two movable knives 3 is 180°.
[0021] Furthermore, one end of the elastic locking tongue 33 facing away from the stopper 51 has a guide portion 35 .
[0022] In this embodiment, the movable knife 3 continues to move outward under the outward force provided by the elastic lever 6, but cannot continue to move outward due to the mutual matching and limiting between the elastic locking tongue 33 and the stopper 51. At this time, the movable knife 3 is elastic in the lateral direction.
