2. Description of the Related Art
TW Pat. No. 1307652 shows a reversely movable and fast operable open end wrench. The open end wrench includes two projections and an open end between the two projections. A jaw block is movably mounted on one of the two projections and cooperates with a jaw formed from the other of the two projections. The jaw block and the jaw delimit an object clamping area therebetween. Additionally, the jaw block is prevented from moving in order to turn an object. However, it is not easy to stop the jaw block from moving inadvertently. Moreover, if the jaw block moves inadvertently, the open end wrench will not be able to withstand a large torque transmission.
The present invention is, therefore, intended to provide a wrench that is easier to assemble and is made at a reduced cost than the prior art.
According to the present invention, a ratcheting wrench having an anti-slip effect includes a body. The body includes a first body portion and a second body portion. The second body portion extends from the first body portion. The second body portion is configured to include a first jaw and a second jaw. The first and second jaws include a gap in between. The second jaw has an edge thereof including a first restraining structure. A ratchet mechanism connects to the second jaw and includes a slider, a pawl, and a biasing member. The slider is movable and disposed on the second jaw. The slider bears the pawl. The pawl includes a second restraining structure. The biasing member connects to the slider. the pawl is selectively changeable between a first position in which the second restraining structure corresponds to and engages with the first restraining structure and a second position in which the second restraining structure disengages from the first restraining structure.
