Patent number: 8935855Abstract: The invention discloses a utility knife preventing its blade from accidental detachment. Prior utility knives may lose constraint on the blade due to tilting of the retaining member when the blade receives external force from the blade holder pulling outward, causing the blade to detach accidentally from the blade holder. In the present invention, the line of the action force in the engagement area of blade and retaining member extends over the axis of axle pin where the retaining member is mounted, so that when the blade receives external force pulling it outward from the blade holder, a counterclockwise torque is formed to the retaining member to allow the retaining member constrain the blade more tightly and thus prevent the blade from accidental detachment.Type: GrantFiled: October 15, 2010Date of Patent: January 20, 2015Assignees: Hangzhou Great Star Industrial Co., Ltd., Hangzhou Great Star Tools Co., Ltd.Inventor: Jianping Qiu

Patent number: 8770067Abstract: Pliers with adjustable jaw span have a first member (1) and a second member (2) which cooperate with each other. A long slot (13) is formed in the first member (1). The second member (2) is connected with the first member (1) by means of a pivot (3) passing through the long slot (13), and rotatable around the pivot (3) relative to the first member (1), while adjusting the span of the jaws by varying the position of the pivot (3) within the long slot (13). The edge of the long slot (13) is provided with ratchet teeth (14). The pivot (3) is engaged with the ratchet teeth (14) by a pawl (31), thus the pivot is movable within the long slot (13) in a first direction and immovable in a second direction which is opposite to the first direction. The pliers are convenient to operate because when the position of the pivot (3) is moved within the long slot (13), the user's operation is required only for the movement in one direction.Type: GrantFiled: July 16, 2010Date of Patent: July 8, 2014Assignees: Hangzhou Great Star Industrial Co., Ltd., Hangzhou Great Star Tools Co., Ltd.Inventor: Jianping Qiu

Publication number: 20130255087Abstract: The present invention first provides a utility knife with a replaceable blade, comprising a knife handle, a blade holder, a blade and a locking device that locks the blade in the blade holder. The blade holder and the blade are enabled to switch between a first position and a second position. When the blade holder and the blade are in the first position, the blade is used for cutting operation, and when the blade holder and the blade are in the second position, both the blade holder and the blade are received in the knife handle. The utility knife further includes a restriction means which is thus arranged as, when the blade holder is in the second position and the locking device is in unlocked state, the restriction means is used for preventing the detachment of the blade from the blade holder by confining the movement of the blade relative to the blade holder.Type: ApplicationFiled: April 6, 2012Publication date: October 3, 2013Applicants: Hangzhou Great Star Industrial Co., Ltd., Hangzhou Great Star Tools Co., Ltd.Inventor: Weiyi Wang
