| 20090293287 | SCISSORS - The present invention provides multi-blades scissors capable of reducing a load generated when a relatively hard object is cut. | 12-03-2009 |
| 20100212165 | Scissors for hairstylist - The present invention relates to a new type of scissors for hairstylist which allows the hairstylist to optimise the cutting operations, in particular by eliminating the need to go over the tip of the locks of hair with the tip of the straight scissors or to go over the locks of hair with trimming scissors in order to move the edge of the lock of hair, which is straight when the lock of hair is cut using the straight scissors or other similar known models of the prior art. Instead, the scissors according to the present invention allows in a single cutting operation to obtain a “perfectly irregular” end of the lock of hair, obtaining an irregular line of perfect measure and combining the gripping comfort and the manageability of the scissors for hairstylists with the efficacy of a tool capable of obtaining a non-straight cut of the lock of hair, conferring in this manner a greater comfort of use and a greater efficacy to the scissors. | 08-26-2010 |

| 20120000078 | BARBER SCISSORS - An object of the invention is to achieve the practicable use of a pair of barber scissors having a sliding-cutting function. In the barber scissors configured of blade bodies each including a cutting blade and handle, a gear accommodation hole is formed at a pivotal joint intersection of one blade body; a rack is formed on the inner-surface of the gear accommodation hole; and a guide groove is formed in the outer-surface of the blade body. In the pivotal joint shaft position of the other blade body, a pinion having arc-shaped teeth to engage with the rack is mounted to rotate together with the blade body; a guide member having a projection to fit into the guide grove is disposed striding the outer-surface of the gear accommodation hole; and a nut is screwed and mounted on the pivotal joint screw shaft protruding from a shaft hole of the guide member. | 01-05-2012 |
| 20140338200 | SLIDE OPERATED SCISSORS - The present invention relates to the field of hand-operated scissors and shears having an ergonomic design in which one of the blade members is slide operated so as to better conform to the configuration of the operator's hand and the desired cutting orientation of the device. The system includes a first blade having a shank and at least one finger ring. A second blade is provided with a pivot to cross the first blade. The second blade having a guide channel in the proximal end thereof. A slide assembly cooperates with a track formed into the shank of the first blade and a thumb ring is secured to the slide assembly. In operation, the users causes the blades to open and close with respect to each other by reciprocating the slide assembly along the track, thereby eliminating the opening and closing motion required in the scissors of the prior art. | 11-20-2014 |
| 20080209741 | Blade structure of an electric hair trimmer - A blade structure of an electric hair trimmer is a blade set, comprising a fixed blade, a movable blade and a vibration seat which is driven by a motor. A front end of both fixed and movable blades is provided with a plurality of teeth to cut the hair by an alternate movement. The lower sections of edge parts at two sides of a tooth of the movable blade are extended outward from top to bottom to form with externally expanded surfaces with sharp transection angles. Accordingly, when hair is cut, a contact area of the edge parts between the hair is decreased, to largely reduce resistance to cutting, such that the hair can be cut off well with improved speed and efficiency and can be prevented from being damaged. Besides, lifetime of usage of blade structure in the electric hair trimmer can be extended. | 09-04-2008 |

The insert functions as both a wear plate and a piercing tip and is indexable in that a non-worn or less worn portion of the wear surface of the wear plate portion of the insert, and non-worn shearing and piercing edges of the piercing tip portion of the insert, can be presented simultaneously simply by rotating the insert 180° and reattaching it to the nose portion of the upper, movable jaw of a metal demolition shears. | 10-11-2012 |
| 20130097875 | PAIR OF SCISSORS WITH AN OPEN SECOND HANDLE - A pair of scissors with an open second handle includes a first blade and a second blade pivotally connected by a pivot member. A first grip portion of the first handle surrounds the basal portion of a user's thumb, the thumb extends out of an inserting hole of the first blade in a lateral direction and presses against a first extension section, so that the user can hold the first grip portion with the thumb without bending too much at the wrist, thus enhancing stability of holding the scissors. The user's middle, ring and little fingers press against the grip section of the second handle, and the index finger rests against the second extension section. Besides, since the second grip portion is an open structure, the fingers of the user are supported but not restricted by the second grip portion, which improves stability and flexibility when using the scissors. | 04-25-2013 |
| 20160052122 | ROTARY EXTENSION ROD - A rotary extension rod includes an outer tube, an inner tube received in the outer tube, a rotatable assembly having a knob, a fixing seat and a link, and a positioning ring deposited on the fixing seat. The knob is rotatably deposited at one end of the outer tube. The fixing seat is received in the outer tube and fixed to one end of the inner tube. The link is between the knob and the fixing seat, and has two opposite first radially raised portions. The positioning ring has two opposite second radially raised portions. By rotating the knob, the first radially raised portions are posed to abut against or depart from the second radially raised portions, so that the positioning ring radially deforms to press against or release the outer tube, in turn allowing the length of the extension rod to be adjusted. | 02-25-2016 |
| 20160375510 | 360.degree. ROTATABLE DRILL SHEAR ATTACHMENT - A 360° rotatable drill shear attachment has a housing with forward extending shear blades and a rearward extending drive bit connectable to a chuck of a portable hand drill. A cowling is fixed to a mounting flange and rearward of the shear housing protectively covering the drive bit and drill chuck. A circular clamp is rotatable and securable to the mounting flange. Left and right rails slide-ably adjust lengthwise and pivotally extend from the clamp along the left and right sides of the drill body to a point beyond the rear of the drill body to a drill rear end. A connector adjustably is fastened to the rear ends of the rails to adjustably draw the ends together for securing the shear attachment to the drill body. The clamp may be loosened to rotate the mounting flange of shear attachment, and shear blades, within the clamp for shear blade orientation anywhere along a 360° axial arc. After which, the clamp is tightened for safe, one-handed operation of the drill with the shear attachment and shear blades oriented in the desired direction. | 12-29-2016 |
