Clamp mechanism of clamp crown block

The utility model discloses a clamp mechanism of a clamp crown block, and relates to the technical field of clamp equipment, in particular to the clamp mechanism of the clamp crown block, which comprises a first lifting hook and a semi-support rectangular cylinder, and the outer surface of a stepped shaft is rotatably connected with an arc-shaped gear long plate. According to the clamp mechanism of the clamp crown block, through the arrangement of the supporting rod, the clamp mechanism of the clamp crown block has the effect of preventing the supporting column from being broken, through the cooperative arrangement of a connecting long plate, a second limiting long rod and a limiting long plate, the purpose that the clamp mechanism is not prone to falling off from a lifting hook is achieved, and through the arrangement of a second supporting ring, the clamp mechanism is not prone to falling off. According to the clamp mechanism of the clamp crown block, the stability is improved, two first gears, two second g
