Patent ID: 7373861

Claim:
A pivoting assembly of a hand tool comprising a tool body, the tool body including a driving portion, a handle and a pivotal portion; the pivotal portion having a first pivoted end and a second pivoted end; the first pivoted end being installed to the driving portion; and the second pivoted end being installed to the handle so that an angle between the handle and driving portion are adjustable; wherein the first pivoted end is formed with a buckling hole; a tooth portion is formed in the buckling hole; the second pivoted end is formed with a post; the post is axially moveable with respect to the tooth portion of the buckling hole; and a bottom of the post is formed with teeth with respect to the tooth portion of the buckling hole; the teeth being axial arranged and being near a lower side of the post; thereby, when a bottom of the post is pressed so that the post inserts into the buckling hole, the teeth of the post will engage to the tooth portion of the buckling hole so that the driving portion is retained to the handle for screwing an object; wherein the driving portion is a ring with inner teeth at a periphery of a wall of the ring; and wherein a wall of the buckling hole of the first pivoted end is formed with a recess; and the recess is installed with a buckling unit; and the post is formed with an annular groove; the buckling unit resists against the annular groove so that when the teeth of the post is engaged to the tooth portion of the buckling hole, the buckling unit is retained in the buckling hole; wherein the buckling unit is formed by a steel ball and a spring resisting against the ball and an inner bottom of the recess; and wherein a top end of the post is firmly secured with a positioning sheet for preventing the first pivoted end from separating from the second pivoted end wherein the positioning sheet is locked to the post by using a screw to pass through a center of the positioning sheet and an upper center of the post.
