Rotatable tool handle

摘要

A rotatable tool handle comprises a first part and a second part which can be switched between an in-line position and an angle position. Further, the locking structure for fixing the first and second parts is disposed between the connecting structures of the first and second parts, so that the engaging points of the first and second parts lie on the rotation axis of the two parts. Moreover, the portion of the first part for forming the recess is harder than the rest of the first part, and the portion of the second part for forming the pivot portion is harder than the rest of the second part, so as to enhance the structural strength of the engaging structure of the first and second parts of the handle.

主权项

1. A rotatable tool handle comprising:
a first part formed with a first slanted end surface at one end thereof, the first slanted end surface being formed at a center thereof with a recess, a first engaging cavity being formed at a bottom of the recess; a second part formed with a second slanted end surface at one end for mating with the first slanted end surface, the second slanted end surface being formed with a pivot portion to be inserted in the recess of the first part, at an end surface of the pivot portion being formed a second engaging cavity formed in the shape of the first engaging cavity, on a peripheral surface of the second part being defined an assembling cavity, and a penetrating hole being formed at a bottom of the second engaging cavity and extending to the assembling cavity, the first and second engaging cavities each including at least two pairs of opposite ends; a control member movably disposed in the assembling cavity of the second part; a pin including an operating end to be inserted in the penetrating hole of the second part and pushed against by the control member, and a drive end to be inserted in the second engaging cavity; an engaging member formed in the shape of the first and second engaging cavities and engaged in the first engaging cavity, the engaging member being aligned with and capable of engaging with the second engaging cavity after the second part rotates 180 degrees; an elastic member disposed between the engaging member and the first engaging cavity in such a manner that the engaging member is pushed against the drive end of the pin by the elastic member, and the pin is pushed by the control member to selectively keep the engaging member between the first and second engaging cavities or to push the engaging member back into the first engaging cavity.
