Two buckling seats 53 are arranged and buckled at two ends of the mounting seat 2 along the length direction of the mounting seat 2, and the two buckling seats 53 can independently swing through the connecting plate 54 and the swing connecting structures at the two ends of the connecting plate; the eccentric 52 is located between two snap seats 53. The buckling base 53 is additionally arranged, so that the contact area between the mounting base 2 and the cutter head bracket 5 is increased, the connection stability of the mounting base 2 and the cutter head bracket 5 is improved, the mounting base 2 can be buckled on the buckling base 53 in the integral structure, the eccentric rod 521 of the eccentric wheel 52 can abut against the conversion part 122, and the compactness of the mounting structure of the trimmer is improved.
The mounting seat 2 is provided with a shielding part 22 for shielding the movable cutter teeth 124, the shielding part 22 comprises a plurality of shielding blocks 221 arranged in a comb-tooth-shaped structure, and a movable gap 3 for the movable blade 12 to slide back and forth is reserved between the shielding part 22 and the fixed blade 11. The fixed blade 11 is located above the movable blade 12, the mounting seat 2 is located below the movable blade 12, meanwhile, the movable teeth 124 can be covered by the fixed teeth 112 of the fixed blade from the top, and the movable teeth 124 can be covered by the shielding portion 22 from the bottom, so that the movable blade 12 can be prevented from being exposed, the user can be prevented from touching the movable blade 12 which swings in a reciprocating manner in the using process, and the using safety of the trimmer is greatly improved.
Meanwhile, the shielding part 22 is arranged in a comb-tooth-shaped structure, so that the hair can pass through the comb-tooth-shaped shielding part 22 when the hair is trimmed, the trimming effect of the trimmer is not affected, and the effect of preventing the fingers or other parts of a user from touching the movable blade 12 from the lower part of the movable blade 12 is achieved.
The fixed blade 11 is provided with two fixed cutter teeth 112 along both sides of the length direction thereof, the movable blade 12 is provided with two movable cutter teeth 124 along both sides of the length direction thereof, and the two shielding portions 22 are provided and located on the two opposite sides of the length direction of the mounting seat 2, respectively. The cutter head with the cutter teeth on the two sides is beneficial to improving the application range of the trimmer, and is convenient for a user to trim hair at different parts when using the trimmer; meanwhile, the shielding part 22 is added to effectively protect the movable blade 12 and prevent the cutter teeth on any side of the movable blade 12 from touching the user.
The comb-tooth-shaped structure of the shielding part 22 is matched with the structure of the fixed cutter teeth 112, and the number, width and gap sizes of the shielding blocks 221 are consistent with those of the fixed cutter teeth 112. The hair can also pass through the blocking portion 22 after passing through the fixed cutter teeth 112, which is beneficial for the hair to be cut off smoothly when the cutter head cuts the hair.
The end of each of the stoppers 221 is provided with a wrapping block 222 for wrapping the end of the fixed cutter tooth 112, and the wrapping block 222 supports the end connected between the stopper 221 and the fixed cutter tooth 112. The structure can directly inject the wrapping block 222 at the end part of the fixed cutter tooth 112 during injection molding of the mounting seat 2, can effectively enhance the connection strength of the fixed cutter tooth 112 and the wrapping block 222, and can form a movable gap 3 for the reciprocating sliding of the movable blade 12; in addition, in the use, the conflict portion of tool bit outermost side is for softer plastic materials makes, can avoid the fixed sword tooth 112 of being made by the metal to produce the fish tail when conflicting human skin, improves the safety in utilization, and the while still can avoid movable sword tooth 124 to follow the side protrusion of tool bit thereby the in-process fish tail user that reciprocates to slide.
The end of each fixed cutter tooth 112 is provided with an inserted bar 113 for improving the connection strength between the fixed cutter tooth 112 and the wrapping block 222, and the inserted bar 113 is inserted into the wrapping block 222 and is fixedly connected with the wrapping block 222. The arrangement of the inserted link 113 can effectively improve the connection strength of the fixed cutter teeth 112 and the wrapping block 222 by increasing the contact area of the fixed cutter teeth 112 and the wrapping block 222, thereby not only greatly enhancing the structural strength of the cutter head part, but also being beneficial to supporting and forming the movable gap 3 between the fixed blade 11 and the mounting base 2. In addition, the width of the insert rod 113 can be smaller than that of the fixed cutter teeth 112, so that the insert rod 113 can be conveniently wrapped by the wrapping block 222 during injection molding, and the width of the wrapping block 222 is not larger than that of the fixed cutter teeth 112, so that hairs can fall between two adjacent fixed cutter teeth 112 conveniently.
As a modified specific embodiment, the mounting seat 2 is fixedly connected to both ends of the fixed blade 11 in the length direction, a swing frame 121 penetrating through the thickness direction of the mounting seat 2 is disposed on one side of the movable blade 12 away from the fixed blade 11, and the conversion piece 122 is disposed on the swing frame 121.
