The invention discloses a locking device of a bicycle seat tube. The locking device is composed of a base, calipers and tooth grooves; the base and a frame beam are connected into a whole; the calipers are arranged on the base, and a calipers shaft of the calipers is fixed on the base; a tooth protruding inward is arranged on each jaw of the calipers, the tooth grooves are formed in the two sides of the seat tube of a bicycle, and each tooth groove is matched with the corresponding tooth; when the calipers are in a closed state, each tooth of the calipers is capable of being connected with the corresponding tooth groove into a whole in a meshed mode, thereby the seat tube is locked and cannot slide downward or swing leftward or rightward; when the bicycle seat height needs to be adjusted, a calipers handle is pinched by a hand so that the teeth can leave the tooth grooves of the seat tube, the seat tube is drawn and inserted in the vertical direction, when the required height is reached, the calipers handle is loosened, the teeth are made to be meshed with the tooth grooves once again, and a bicycle seat can be located.
