    • A swing wrench includes a fixing jaw 1, a moving jaw 2, an acting set 3, and a handle 4 pivotally fixed to the bottom of the fixing jaw 1. A fixing element 6 is disposed between the bottom of the fixing jaw 1 and the front end of the handle 4. A limiting section 64 is disposed around the fixing element 6. A fixing part 45 is formed at the front end of the handle 4, opposite to the fixing element 6. The limiting section 64 of the fixing element 6 can engage or move away from the fixing part 45 of the handle 4. When the limiting section 64 is away from the fixing part 45, a swing space 7 is formed in between for the handle 4 to pivotally swing with respect to the fixing jaw 1.
