ABSTRACT:
A tool coupling device including a seat body, a ratchet locating mechanism and a transmission member disposed in the seat body. The ratchet locating mechanism has a controlling disc and a working stem projecting from the controlling disc. One end of the working stem has a first stopper block. A second stopper block is connected with the working stem next to the first stopper block. A pair of radially symmetric controlling keys are connected with the working stem next to the second stopper block. The controlling keys serve to drive two chucking pins disposed in the transmission member to move up and down so as to achieve ratchet effect. Therefore, the rotational direction of the tool can be changed.
