Abstract
A rotatable fastening device disclosed in the present disclosure includes a rotating seat and an impact element. The impact element is one-way pivoted at the rotating seat. The rotating seat is rotated along a rotation axis and detachably connected between a driving tool and an element to be rotated. The weight and kinetic energy of the impact element will provide a one-way tangential impact force around the rotation axis with of rotation.
Claims16
A rotatable fastening device, connected between a driving tool and an element to be rotated, comprising:
- a rotating seat rotated along a rotation axis and comprising:
- a driving end detachably connected with the driving tool;
- and
- a fastening end detachably connected with the element to be rotated for driving the element to rotate;
- an impact element pivotally configured at an outside of the rotating seat, wherein the impact element is driven by the rotating seat to surround the rotation axis for producing a one-way tangential impact force;
- and
- a one-way position-limiting assembly disposed on the rotating seat and selectively engaged with the impact element;
- wherein when the rotating seat rotates toward a first rotation direction, the one-way position-limiting assembly provides an elastic restoring force to rotate the impact element so as to allow the rotating seat to receive the one-way tangential impact force of the impact element surrounding the rotation axis;
- wherein when the rotating seat rotates toward a second rotation direction, the impact element is not driven by the one-way position-limiting assembly.

A rotatable fastening device, comprising:
- a rotating seat rotated along a rotation axis, wherein the rotating seat comprises:
- a fastening end detachably connected with the element to be rotated for driving the element to rotate;
- and
- at least one position-limiting groove disposed at an outside of the rotating seat;
- a one-way position-limiting assembly comprising:
- at least one pivotal tooth pivotally disposed in the position-limiting groove;
- and
- an elastic restoring element disposed in the position-limiting groove for pushing the pivotal tooth outwards;
- and
- an impact element having a pivoting hole, wherein the pivoting hole is pivoted at the outside of the rotating seat corresponding to the pivotal tooth and has a plurality of one-way position-limiting teeth formed therein;
- wherein the one-way position-limiting teeth cooperates with the pivotal tooth to allow the impact element to be driven through a stored force of the elastic restoring element when the rotating seat rotates toward a first rotation direction and to be limited when the rotating seat is stopped for receiving a one-way tangential impact force of the impact element surrounding the rotation axis;
- wherein the impact element is not driven by the rotating seat when the impact element inertially rotates toward a second rotation direction.
