Patent attributes
There is disclosed a selective one-way wrench with a device for retaining a socket. The selective one-way wrench includes a handle and a head formed at an end of the handle. The retaining device includes a cover installed on the head. Two parallel grooves are defined in the internal side of the cover. A stop is formed between the grooves. A shackle is put between the cover and the head. The shackle includes two slides sliding in the grooves. The shackle defines an opening larger than the socket. The shackle includes a retaining portion at a front end. An arched leaf spring is compressed between the shackle and the stop. Thus, the shackle is normally at a locking position and will be returned to the locking position after it is moved and released. Because of the above-mentioned design, the socket can easily be retained and released. As the slides slide in the grooves, the operation of the retaining device is smooth. Therefore, its lifecycle is long.
