The invention relates to a rescue tripod which comprises a top cylinder, a synchronous locking mechanism, three supporting legs, a winch and a pulley. The synchronous locking mechanism comprises a vertical shaft, three adjusting grooves, a lower limiting disc, an upper limiting disc, a limiting bolt, an adjusting round rod, a lifting ring bolt and a locking rod, the vertical shaft is vertically and elastically connected into the top cylinder in a sliding mode, and the three adjusting grooves, the lower limiting disc, the upper limiting disc, the limiting bolt, the adjusting round rod, the lifting ring bolt and the locking rod are all annularly formed in the side wall of the middle of the vertical shaft. The lower part of the vertical shaft extends out of the top cylinder and is sequentially connected with an adjusting round rod and an eyebolt; three locking rods are transversely and elastically connected to the side wall of the top cylinder in a sliding manner, are annularly and uniformly distributed on the top cylinder, and are in one-to-one correspondence with the adjusting grooves; a rotating shaft is arranged at the upper end of each supporting leg to be rotationally connected with the top cylinder, and the rotating shafts are matched and meshed with the outer ends of the locking rods one by one. According to the tripod, the three supporting legs can be conveniently and rapidly locked and unlocked at the same time, and operation and use of the tripod are greatly facilitated.
