Patent number: 11253986Abstract: A handle includes an inner core and a gripping portion disposed around the periphery of the inner core, and at least one chamber is formed between the inner core and the gripping portion. A hammering tool includes the handle. When the hammering tool is used for striking, the internal damping slot of the hammerhead can use a damping material as a first buffering and absorb the vibration and impact force of the hammerhead, which are then delivered to the inner core of the handle, the inner damping layer and its chamber serve as a second buffering and absorb the vibration and impact force delivered from the inner core of the handle, and finally, the outer damping layer serves as a third buffering and absorbs the vibration and impact force delivered from the inner damping layer.Type: GrantFiled: November 30, 2016Date of Patent: February 22, 2022Assignees: Hangzhou Great Star Industrial Co., Ltd., Hangzhou Great Star Tools Co., Ltd.Inventor: Wentian Yu

Patent number: 9772093Abstract: A lens has a front surface, a rear surface, a side surface extending between the front surface and the rear surface. The rear surface defines a rear-facing chamber. The front surface has a central surface and an edge surface connected in a surrounding manner with the central surface, and the edge surface extends between the central surface and the side surface. The lens is an axisymmetric body and defines a central axis. The lens cooperates with the LED light source or similar light source which are located at the central axis and can move within the chamber, to form a lens system, so as to achieve a high capacity factor of the emergent light emitted from the light source, and functions of collimating and focusing for the incident light. This lens system can be applied to a flashlight with the function of variable focus.Type: GrantFiled: April 16, 2014Date of Patent: September 26, 2017Assignees: Hangzhou Great Star Tools Co., Ltd., Hangzhou Great Star Industrial Co., Ltd.Inventor: Wentian Yu

Patent number: 9421675Abstract: The invention provides an adjustable torque screwdriver, including a torque input assembly and a torque output assembly, and further including a ratchet pair, which comprises a first ratchet and a second ratchet, respectively having circular teeth. The torque input assembly transmits the torque to the first ratchet, and the second ratchet then transmits the torque to the torque output assembly, and the circular teeth are arranged to enable the ratchet pair to slip either clockwise or counterclockwise, but not to slip in the respective opposite direction. The adjustable torque screwdriver also includes an adjusting assembly and an elastic assembly, the elastic assembly exerting pressure to the ratchet to tightly fit the ratchet pair, the adjusting assembly loading and unloading the elastic assembly, thereby adjusting the exerted pressure and the in-between fitting tightness of the ratchet pair, thus adjusting the torque for the ratchet pair to slip.Type: GrantFiled: September 4, 2012Date of Patent: August 23, 2016Assignees: Hangzhou Great Star Tools Co., Ltd., Hangzhou Great Star Industrial Co., Ltd.Inventor: Wentian Yu
