The specific embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, below the utility model will be further described by the specific embodiment.

Of the present utility modelly a kind of train tail host is locked at the device of last vehicle of train, mainly comprises housing 10, fixedly latch hook 21, movable latch hook 22, worm screw 31, worm gear 32, ratchet 41, ratchet 42, ratchet fixed cover 43, spring 44, release bar 50, triangle lock core 60 and circular spanner 70.

Fixedly latch hook 21 is fixedly connected on a side of housing 10, by first fixedly latch hook 211 and second fixedly latch hook 212 form.

Movable latch hook 22 is fixedly connected on the worm gear 32, is made up of the first movable latch hook 221 and the second movable latch hook 222.
