Publication number: 20230349538Abstract: A standing light includes a light assembly, a support rod assembly, and a housing assembly. The support rod assembly is configured to support the light assembly. The housing assembly or the support rod assembly is formed with a power access interface for being connected to a power supply. The standing light further includes a mounting assembly configured to detachably install the light assembly to the support rod assembly. When the light assembly is installed to the support rod assembly, the light assembly is capable of being powered by the power supply connected to the power access interface. The light assembly is further formed with a power supply access interface for accessing power, and when the light assembly is detached from the support rod assembly, the light assembly is capable of being detachably connected to a battery pack through the power supply access interface.Type: ApplicationFiled: July 11, 2023Publication date: November 2, 2023Inventors: Shichun Tao, Xiang Chen, Shubin Tong, Tian Yu

Publication number: 20230339081Abstract: A power tool includes a main housing, a drive mechanism, a working head, and a connection assembly. The connection assembly includes an input portion connected to the drive mechanism and an output portion connected to an output shaft. The connection assembly rotates the working head about a first axis relative to the main housing. The power tool includes a first transmission path. When the working head rotates about the first axis relative to the main housing, components in the first transmission path are allowed to deform or to be displaced along a direction of the first transmission path.Type: ApplicationFiled: July 6, 2023Publication date: October 26, 2023Inventors: Hanqing Zheng, Xiangqing Fu, Changwei Zuo, Shubin Tong, Xu Wang, Binbin Chen

Publication number: 20230019359Abstract: A torque output tool includes an output shaft, a motor, a transmission assembly, and a gearbox. The gearbox is used for accommodating the transmission assembly. The transmission assembly includes a first planetary gearset and a second planetary gearset. The transmission assembly is capable of being switched to a first state and a second state such that the transmission assembly outputs a first gear ratio or a second gear ratio separately, where the first gear ratio is greater than the second gear ratio. When the transmission assembly outputs the first gear ratio, a rotational speed of the output shaft is greater than or equal to 300 r/min and less than or equal to 800 r/min. A length of the gearbox in an axial direction is greater than or equal to 38 mm and less than or equal to 46 mm.Type: ApplicationFiled: September 30, 2022Publication date: January 19, 2023Inventors: Chunrui Li, Shubin Tong, Hejun Wang, Hanqing Zheng

Publication number: 20150306758Abstract: An accessory device for a power tool includes a first moving member, a second moving member, a functioning member associated with at least one of the first moving member and the second moving member, and a connecting assembly for connecting the first moving member and the second moving member. The first moving member is provided with a first installing member and the second moving member is provided with a second installing member. The first installing member and the second installing member are located in an installation state when the first moving member and the second moving member are moved towards each other to a preset position. The connecting assembly forces the first moving member and the second moving member to move simultaneously in a straight direction to enable the first installing member and the second installing member to be moved into or out of the installation state.Type: ApplicationFiled: April 16, 2015Publication date: October 29, 2015Inventors: Cuihua Chen, Shubin Tong
