A wrench having a ratchet head able to vertically and horizontally rotate for 360 ° includes a tang having a longitudinal slit of predetermined length in the center a tong at front end composed of a pair of symmetrical prongs for rotatably engaging with a drum-shaped ratchet head which has a solid rectangular driver on underside and a hexagonal box driver on the top, a handle slidably sleeved on the tang having a small upper through hole in a top for disposing an internally threaded pressed button and a large lower through hole in an underside facing the upper through hole, a bolt inserted through the lower through hole, the slit and screwed with the press button, a positioning cap fixed within the large lower through hole and a spring biased between the cap and a stop head at lower end of the bolt engageable within one of the retaining grooves under the tang. Therefore, the ratchet head is vertically rotated for 360°, the drivers are horizontally rotated for 360° either, and the handle is slidably fixed on the tang.
