[0060] 2. The worker holds the handle 4 of the device and moves the hook upward. After the hook is completely separated from the disconnector clamp, the worker rotates the hook 90 degrees so that the hook belly is parallel to the disconnector;

[0061] 3. Rotate the rotating connection block 602 to lock the fastener 6 and fix the connection member 3 to prevent the connection member 3 from moving up and down and affecting the handling and loading and unloading of the device;

[0062] 4. Repeat steps 2 and 3 to remove the other set of hooks from the disconnector clamp;
