Abstract
A rotary fastening device includes a rotating axial member and an inertia member. The rotating axial member includes a base body, an input end, an output end and an engaging portion. The input end is disposed at one end of the base body and selectively connected to a wrench. The output end is disposed at the other end of the base body. The engaging portion is disposed on the base body. The inertia member is detachably connected to the rotating axial member, and includes a gravity portion and an engaging hole. The gravity portion is extended toward the output end of the rotating axial member so as to form an annular space. The engaging hole is communicated to the annular space.
Claims8
A rotary fastening device, comprising:
- a rotating axial member, comprising:
- a base body;
- an input end disposed at one end of the base body and for connecting to a wrench;
- an output end disposed at the other end of the base body;
- and
- an engaging portion disposed on the base body;
- and
- an inertia member detachably connected to the rotating axial member, and the inertia member comprising:
- a gravity portion protruding from a surface of the inertia member and extended toward the output end of the rotating axial member so as to form an annular space;
- an engaging hole communicated to the annular space;
- and
- a convex portion protruding from another surface of the inertia member and extended toward the input end of the rotating axial member, wherein a position of the convex portion corresponds to a position of the annular space;
- wherein a center of gravity of the rotary fastening device approaches to the output end.
