Document Type and Number:
Japanese Patent JP7274593
Kind Code:
B2
Abstract:
Disclosed are a clutch device, a drill chuck, a power tool, and a bidirectional rotation method of the drill chuck. The clutch device comprises a return elastic member (216), a transmission assembly and a rotating portion (203), wherein the transmission assembly comprises at least two engagement portions which are arranged opposite each other; the engagement between the two engagement portions enables a front body (101) and a rear body (100) to rotate synchronously; the rotation of the rotating portion (203) in a first direction enables the return elastic member (216) to be compressed, such that the two engagement portions are disconnected; and the rotation of the rotating portion (203) in a second direction enables the compressed return elastic member (216) to be reset, such that the two engagement portions are engaged. The drill chuck comprises a front body (101), a rear body (100), a clamping jaw (102) and the clutch device; and the power tool comprises a driving shaft and the drill chuck. The device can guarantee the mounting of a drilling tool on a drill chuck in a more stable manner, thereby avoiding the occurrence of loosening or detachment, and enabling the drilling tool to be replaced in a more convenient manner.
