Document Type and Number:
WIPO Patent Application WO/2011/099654
Kind Code:
A1
Abstract:
The present invention relates to a driver. The driver comprises: a front body in which a first main gear is provided; a rear body in which a second main gear is disposed coaxially to the first main gear; a connection ring disposed between the first and second main gears and including at least one support part on the outer surface thereof; at least one side gear inserted in the support part and engaging with the first and second main gears to form a right angle with each of the first and second main gears; a main axle; and an elastic member. A driver bit is coupled to the main axle through a groove formed in one end of the main axle, and the main axle is slidable when the other end of the main axle is inserted into the center holes of the first main gear, the connection ring, and the second main gear. The elastic member applies an elastic force to the main axle so that the main axle can return to an original position from a retracted position. Therefore, a user can select an RPM adjustment mode and a torque adjustment mode, and thus operating efficiency can be improved.
