An adjustable blade attachment is provided that captures an inner blade relative to the outer blade. A mounting bracket captures the inner blade and provides access to attach the blade assembly. A hinge or metallic stamping extends through the mounting bracket and is adjustable to change the force exerted on the mounting bracket. The adjustment to hinge on the mounting bracket changes the tensile force between the inner and outer blade of the blade assembly. In this way, the hinge provides an adjustable component that can increase or decrease the tensile force exerted between the inner and outer blade to adjustably separate the inner and outer blades and reduce friction during operation of the blade assembly.

There are many trimmer models with 2 main parts, the static comb blade and the side moving cutter blade driven by electric motor/vibrator. These blades differ in many ways, shapes, sizes . . . which require fine adjustments and tenth of millimeter clearance at the end of the blades. Some models come with an adjuster that fits its model only with a fixed clearance that cannot be modified and does not fit other models. The proposed inventions are universal trimmer blades adjusters that fit most trimmer blades models and the clearance can be varied to meet the users' requirements. First invention design has one moving part with non-linear smooth adjustments and second invention design has two moving parts with linear fine adjustments.

The haircutter according to the invention serves for trimming and styling hair and comprises a grip and a blade head connected with the grip. A working section is disposed at one longitudinal face of the blade head and recessed from an alignment line of the longitudinal face. A haircutting blade having at least one cutting edge is accommodated in the blade head and disposed so as to expose at least part of its cutting edge in the working section and to not protrude beyond the alignment line. The blade head comprises a guiding device having at least one placing surface for the hair to be trimmed so that the hair to be trimmed lies at a defined angle to the cutting edge as the placing surface is placed against the hair.

The present invention relates to a cutting unit for a hair-cutting device. A cutting unit 14 is provided that comprises a tapered stationary guard blade 18 and a reciprocating cutter blade 16 in which the stationary guard blade is arranged to be moved perpendicular to the reciprocal motion of the cuter blade to allow the selection of different length settings. The guard blade may be biased to a minimal length setting. The stationary guard blade may be configured to be actuated by a user to allow a stepless change of the cutting length, when the stationary guard blade is pushed from its biased start position to the other end position.

The present invention relates to a beard trimmer having one or more rotary cutting heads having a moving blade and a fixed blade, each head being surrounded by a telescopic comb in the form of a crown, said comb being height adjustable and making it possible to adjust, in use, the distance between said blades and the skin and thus to set the cutting of the beard hairs to the desired length.

The hair clipper of the present invention includes an adjusting device for adjusting a clipping height. The adjusting device includes an attachment, a handle ring, and a connection mechanism. The attachment is allowed to move in a predetermined moving direction relative to a blade block. The handle ring is allowed to rotate around a rotation axis extending along the moving direction. The connection mechanism moves the attachment with rotation of the handle ring. The connection mechanism includes a cam groove and a linking pin allowed to move along the cam groove. The cam groove includes a first side and a second side opposite to each other. The first side includes: plural step parts which are formed in different positions in the moving direction and extend in a direction perpendicular to the moving direction; and a slope part configured to connect the step parts.
