Preferably, the side of described uncoupling device is provided with a seal cover cap.

Preferably, described seal cover cap is provided with a chute, and the end of uncoupling crank extends the chute of seal cover cap, and slides in chute.

Preferably, described returning device is a crank spring, and an end of crank spring is installed on the spring pulling seat of uncoupling device end, and the other end is connected with the uncoupling crank; Perhaps, described returning device is the spring that is sleeved on the cylinder piston of uncoupling cylinder.

The beneficial effects of the utility model are: realize manually and automatically decomposing between the tight lock coupler, made things convenient for execute-in-place; Adopt linkage, it is more rationally compact that decomposer is arranged, hitch length shortens greatly, sealing effectiveness improves greatly, reduced the influence of external environment to the hitch associated mechanisms, make hitch bigger simultaneously at the longitudinal space Design freedom, can be integrated with other modular unit of coupler buffering device more easily.
