摘要： An impact tool includes an electric motor, an output shaft, a grip, and an impact assembly. The impact assembly is used for providing an impact force for the output shaft and includes an impact block driven by the electric motor and a hammer anvil mating with the impact block and impacted by the impact block. The maximum radial dimension of the impact block is greater than or equal to 44 mm and less than or equal to 50 mm, and tightening torque outputted from the impact tool to a workpiece is greater than or equal to 250 N·m. The impact tool ensures good impact performance and is compact and light.

摘要： An impact tool includes an impact assembly and a housing. The impact assembly is used for applying an impact force to an output shaft and includes a main shaft driven by a drive shaft, an impact block connected to the main shaft, and a hammer anvil mating with and struck by the impact block. A motor is at least partially accommodated in the housing. A length L from a rear end of the housing to a front end of the output shaft is greater than or equal to 78 mm and less than or equal to 97 mm and an outer circumferential diameter D of the housing is less than or equal to 60 mm.
