Quick rotatable wrench

摘要

A quick rotatable wrench includes a first bar including a first position limit portion and a rotary connector, a second bar including a second position limit portion having a shape complementary to the first position limit portion and a recessed accommodation chamber, and a position limit device to secure the rotary connector to the inside of the recessed accommodation chamber in such a manner that the first bar is movable relative to the second bar between an engaged position where the first and second position limit portions are engaged together to secure the first bar and the second bar together and a released position where the first and second position limit portions are disengaged from each other and the rotary connector is rotatable in the recessed accommodation chamber for allowing relative rotation between the first bar and the second bar.

主权项

1. A quick rotatable wrench, comprising:
a first bar comprising a first surface, a first position limit portion located at said first surface and a rotary connector extended from said first position limit portion; a second bar comprising a second surface, a second position limit portion located at said second surface in a complementary shape to fit said first position limit portion, and a recessed accommodation chamber formed in said second position limit portion and adapted to accommodate said rotary connector for enabling said first bar to be movable relative to said second bar between an engaged position where said first position limit portion and said second position limit portion are engaged together to lock said first bar and said second bar together and a released position where said first position limit portion and said second position limit portion are disengaged from each other and said rotary connector is rotatable in said recessed accommodation chamber for allowing said first bar and said second bar to be moved relative to each other; and a position limit device mounted at said second bar to secure said rotary connector of said first bar to the inside of said recessed accommodation chamber of said second bar; wherein when said first bar is in said released position, said rotary connector is stoppable against an inner wall of said recessed accommodation chamber to bias said second bar relative to said first bar, wherein said rotary connector of said first bar comprises a spherical head secured to the inside of said recessed accommodation chamber by said position limit device; wherein said recessed accommodation chamber of said second bar is a circular blind hole so that said inner wall surrounds said spherical head.
