Title:
DRILL CHUCK AND POWER TOOL
Document Type and Number:
WIPO Patent Application WO/2024/036484
Kind Code:
A1
Abstract:
A drill chuck and a power tool. In the drill chuck, a front body is provided with a plurality of clamping jaw grooves (102), and the plurality of clamping jaw grooves are uniformly distributed in an axial direction of the front body (103), such that after clamping jaws (100) are installed, the clamping jaws can easily apply uniform force to a drilling tool, thereby ensuring the stability and safety in the process of using the drilling tool. The directions of the guiding of the clamping jaw grooves are radially set along the front body, such that the plurality of clamping jaws can be driven by a rear body (104) to directionally move under the limitation of the corresponding clamping jaw grooves, and radial movement of the clamping jaws along the front body is conducive to widening the range of diameter of the drilling tool that matches the drill chuck and shortening the lengths of the clamping jaws, and thus helps to reduce the overall axial length of the drill chuck.
