Abstract

A bidirectional wrench comprises a working portion (10) and a handle (20). The working portion (10) comprises a main shaft (100) used for outputting a torque and having an axial line perpendicular to the handle (20); a driving gear (312), a driven gear (322), and an intermediate gear shaft (330) that are sleeved on the main shaft (100), wherein an axial line of the intermediate gear shaft (330) is perpendicular to an axial line of the main shaft (100); and intermediate gears (331, 332) mounted on the intermediate gear shaft (330). The working portion (10) further comprises a first ratchet surface (311) rotating with the driving gear (312), a second ratchet surface (321) rotating with the driven gear (322), a first pawl element (211) and a second pawl element (212) capable of driving the main shaft (100) to rotate, and a changeover switch capable of making the first pawl element (211) and the second pawl element (212) enter a first state and a second state. The bidirectional wrench can switch between two working modes, and when an input torque changes directions alternately, the direction of an output torque remains unchanged.
