The invention discloses a supporting leg assembly of a child safety seat. A middle square pipe is sleeved with a supporting base which is supported by a vehicle bottom plate. An elastic locking mechanism is arranged on the supporting base and comprises hinge pins which are matched with a first locking hole and a second locking hole, a first inclined plane is arranged on the inner side of the supporting base, and a second inclined plane is arranged on the outer side of a locking block. When the first inclined plane of the supporting base presses the second inclined plane of the locking block, the front end of the locking block retracts into the inner wall of the middle square pipe. The supporting leg assembly has the advantages that a user can adjust the height of the supporting leg assembly only by pushing upwards or pulling downwards the supporting base with one hand, operation is convenient to conduct, the adjusting range of the height of supporting legs can be extended to 260 mm, and therefore the adaptability requirement of supporting legs of all vehicles with ISOFIX connectors on current domestic and foreign markets can be met.
