The first elastic component is sleeved on the first screwing member, and the first elastic component is elastically disposed between the inner circumferential surface and the sleeve, so that the driving head is elastically positioned by the elastic force of the first elastic component. On the body.

The diameter of the second outer peripheral surface of the driving head is slightly smaller than the first distance of the notch of the body, that is, the driving head can be arbitrarily adjusted by the notch of the body, and the driving head system is rotated when the hand grip body is rotated. Rotating to the most appropriate angle and rotating the screw for easy operation. The first elastic component is elastically mounted on the inner circumferential surface of the body and between the sleeves, so that the driving head is elastically positioned on the body by the elastic force of the first elastic component, and is driven by the first screwing member as an axis. In the case of the head, the first elastic member has an elastic resistance and has a better swirling state.
