  • Patent number: 9908249
    Abstract: The present invention relates to a hair clipping device, comprising: —a housing (12); —a cutting assembly (14) which is arranged on one end of said housing (12) and comprises a stationary blade element (22) with a circumferentially arranged toothed cutting edge (26) surrounding the stationary blade element (22) and a moveable blade element (24) with a circumferentially arranged second cutting edge (28) surrounding the moveable blade element (24), wherein the stationary blade element (22) and the moveable blade element (24) are arranged substantially parallel to each other; and —a motor (34) for driving a drive shaft (36) in a rotatory manner; wherein the drive shaft (36) is coupled to the moveable blade element (24) via an eccentric coupling mechanism (38) that translates a rotatory movement of the drive shaft (36) into an eccentric movement of the moveable blade element (24).

  • Publication number: 20040068875
    Abstract: The present invention relates to a handheld planer with a chip-ejecting duct, more particularly, the chip ejecting direction of the chip-ejecting duct is changeable. The planer comprising: a driving motor, a transmission strap, a tool blade, a blade shank, a button for adjusting cutting depth, an adjustable base, a motor output shaft, a fan, an air department, a outlet for airflow out, the outlets for chips and a chip-ejecting duct. There is a plate in the chip-ejecting duct, and the plate divide the chip-ejecting duct into left and right departments. There are inlets for airflow into and inlets for the chips into on the wall of the duct, and the wall respectively face the said plate downwardly and upwardly. The inlets for airflow into and inlets for chips into respectively communicate with the said outlet for airflow and outlet for chips out on the planer, thereby formed the chip ejecting passages and outlets for exhausting chips in opposite directions.

  • Patent number: 6381853
    Abstract: A tensioning means for a rotary handpiece is described in which the handpiece (2) is characterized in having a planar rotating blade (12) provided with a plurality of teeth and a plurality of cutting elements (22) capable of moving reciprocally in a linear direction in response to contact by the teeth of the rotary blade (12) when it rotates. There is a clearance gap between the rotary blade and the cutting chips, the size of which is varied by movement of the tensioning means so that the cutting characteristics of the handpiece are changed in accordance with movement of the tensioning means which applies tension to the rotary blade. In one form, the tensioning means comprises a rotating spindle, a flanged member, a bearing member and a resilient means such as an O-ring located between the flanged member and bearing member.

  • Patent number: 4037323
    Abstract: The trimming device has a blade driven by a shaft to have each end pass over cutting teeth at the forward edge of a circular cutting plate. The drive mechanism may be a belt or a gear train driven by a motor which is mounted on a frame to which a top and bottom plate is secured. A housing encloses the drive mechanism having a handle containing a switch and a receptacle for the prongs on a plug-in cord.

  • Patent number: 3945116
    Abstract: A portable hand-held shear for cutting grass and the like comprising a housing enclosing an electric motor and forming a handle. The motor includes an output rotary shaft which, through a gear train, drives a rotary blade. A stationary bed knife assembly connected to the housing cooperates with the rotary blade in scissor-like fashion to cut grass.An improved cutting assembly is described in which the rotary cutting blade member, of particular design and positioned in a floating relationship above the stationary bed knife assembly, is inclined into engagement with the cutting teeth projecting from the stationary bed knife assembly, also of particular design, in such a manner to improve the performance of the shear. The improved cutting assembly further includes a rotary hub drive member which cooperates with the shear housing and the bed knife to eliminate clogging and partially overlaps the bed knife assembly's cutting teeth to further improve the performance of the shear.
