Quick locking and supporting device

The utility model relates to a supporting device of a pouring formwork, in particular to a fast locking supporting device which comprises a base and a supporting portion used for supporting the pouring formwork, and the supporting portion can move up and down along the base. The device further comprises a limiting part, the limiting part is arranged on the base, and when the supporting part moves downwards along the base, the limiting part blocks the supporting part. According to the rapid locking supporting device, through cooperation of the limiting part and the clamping part, the clamping part can automatically cross the limiting part in the rising process of the supporting part, the rising process is not limited by the limiting part, and therefore efficiency in the rising and falling process of the supporting part is greatly improved; and the limiting part can automatically clamp to prevent the supporting part from moving downwards, so that a self-locking structure is formed, manual intervention is not ne
