摘要： An impact rotary tool includes an output shaft having an anvil at an end portion thereof, a hammer having a projecting portion applying an impact force to the anvil under a predetermined condition, a driving shaft connected to the hammer through a cam mechanism, and a changeover mechanism for changing the connection between the driving shaft and the output shaft. The mechanism is arranged along with a common axis defined by the driving shaft and the output shaft. The changeover mechanism includes a connecting member accommodated into the driving shaft in a first condition, and connecting the driving shaft and the output shaft in a second condition.

摘要： A drilling and/or chiseling device has a drive spindle (19) for a drilling and/or chiseling tool with two ring gears (17, 18) of different sizes, a countershaft (1) with a drive pinion (15), a wobble drive (7) for a striking mechanism, mounted on the countershaft (1), and a switching sleeve (9), mounted on the countershaft (1) so that it can be shifted axially by a switching element (20). The switching element displaces the switching sleeve (9) into four different modes of operation of the drilling and/or chiseling device.
