Document Type and Number:
WIPO Patent Application WO/2022/188555
Kind Code:
A1
Abstract:
A multifunctional electric tool. The tool comprises a tool drive mechanism, which can move around the axis of an output shaft and comprises at least one hanging and fastening device, a clamping device and a locking device, wherein the hanging and fastening device can apply a tensioning force to the clamping device; the clamping device has an open position and a closed position; and the locking device has an unlocking position and a locking position. A force applied on the locking device by a tool head makes the locking device move from the locking position to the unlocking position; and in at least one locking position, the tensioning force applied to the clamping device by the hanging and fastening device is released by the locking device by means of locking the hanging and fastening device. The tool has the advantage of it being possible to mount the tool head with one hand by means of merely pressing the locking device, and also completely eliminates the instability after being disturbed, such that the tool is more stable and reliable regardless of whether the clamping device is opened for clamping, is closed for releasing, or switches the position.
