During work, first rotate the rotating part 201, so that the pin 303 is located inside the card slot 203, then place the heavy object on the hook 204, the crane raises the hook 204. Since the hoisting ring is inclined at an angle of 10 degrees, when the heavy object is lifted, the hoisting ring 106 is vertical, so that the first fixing plate 304 deflects around the second rotating shaft 103, driving the swivel ring 301 and the connecting arm 302 to deflect, so that the pin 303 disengages from the card slot 203. When the heavy object is lowered, the hook 204 is no longer affected by the force of the heavy object. At this time, since the mass of the counterweight 202 is greater than that of the hook 204, the rotating part 201 will rotate counterclockwise, so that the hook 204 can be disengaged from the lifting rope of the heavy object. The release device 3 includes a swivel ring 301, a connecting arm 302 is fixedly connected to the outer surface of the swivel ring 301, a pin 303 is fixedly connected to the lower surface of the connecting arm 302, and the pin 303 is located inside the card slot 203.

The crane raises the hook 204. Since the sling ring is inclined at an angle of 10 degrees, when the heavy object is lifted, the sling ring 106 becomes vertical, which causes the first fixing plate 304 to deflect around the second rotating shaft 103, driving the rotating ring 301 and the connecting arm 302 to deflect, and further causing the latch 303 to disengage from the card slot 203. When the heavy object is lowered, the hook 204 is no longer affected by the force of the heavy object. At this time, since the mass of the counterweight 202 is greater than that of the hook 204, the rotating member 201 will rotate counter - clockwise, and the hook 204 can be disengaged from the lifting rope of the heavy object.
