WRENCH COMBING SLEEVE
Document Type and Number:
WIPO Patent Application WO/2016/019617
Kind Code:
A1
Abstract:
A wrench combining a sleeve comprises a wrench (1), a rotating sleeve (2), a locking strip (3), a hexagonal sleeve (4), and magnetic steel (5). The locking strip (3) is mounted at the bottom of the rotating sleeve (2). The hexagonal sleeve (4) is disposed in the rotating sleeve (2). The magnetic steel (5) sleeves one end of the hexagonal sleeve (4), so as to form a sleeve device. The wrench (1) penetrates through the sleeve device. The outline of the external circle of the locking strip (3) is of a gradually-opened surface structure, the rotating sleeve (2) matches the external circle contact surface structure of the locking strip (3) and the gradually-opened surface structure. The magnetic steel (5) absorbs a screw. When the sleeve device slides to a corresponding position on the wrench (1), the fixation or release of the sleeve device is controlled by means of the two gradually-opened surfaces, and therefore, functions of operating a screw or an inner angle screw are achieved, and the functionality of the wrench is effectively improved.
