The invention relates to a container spreader. The rotating angle displacement mechanism comprises a pulling plate, a pawl, a ratchet wheel, a first transmission gear, a second transmission gear, a rotating transmission assembly and a rocking plate, the pulling plate is connected with the pawl, the ratchet wheel is matched with the pawl and connected with the first transmission gear, the first transmission gear is meshed with the second transmission gear, and the second transmission gear is meshed with the rotating transmission assembly. The second transmission gear is connected with the rocking plate through the rotary transmission assembly, and the rocking plate is rotated through the rotary transmission assembly; the transmission shaft is connected with the rocker panel, and the rocker panel drives the transmission shaft to rotate anticlockwise or clockwise; the pull shaft is connected with the transmission shaft and generates linear motion through rotation of the transmission shaft; and the unlocking and locking mechanism is connected with the pull shaft and is driven by the pull shaft to be connected with or disconnected from the hoisted container. According to the lifting appliance, the risk of damage caused by spring fatigue and uneven stress of an existing lifting appliance is reduced, and the overall use efficiency, reliability and safety of the lifting appliance are improved.
