Abstract
A vacuum device for a drilling hand tool includes a housing, a connection piece, a blower, and a collecting vessel. A drilling tool can be plugged into and through the connection device along a working axis. The blower conveys dust-laden air from the connection piece into the collecting vessel. The connection vessel includes a tray cartridge which can be removed from the housing, and a locking bar. The locking bar is hinged on the tray cartridge or on the housing and can pivot between a locking position and an unlocked position. When the locking bar is in the locking position, it presses the tray cartridge against the housing to provide pretensioning.
