Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] Example: like Figure 1-8 As shown, this embodiment provides a container spreader that is easy to position, including a spreader body 10, and a container body 40 is arranged below the spreader body 10; The outer wall of the sling body 10 is provided with a circular connecting plate 20, and a driving assembly 50 is provided on the sling body 10. A guide hopper 30 is provided at the bottom of the circular connecting plate 20. The circular connecting plate 20 is connected to the guide hopper 30, and the driving assembly 50 is connected to the circular connecting plate 20, so that the circular connecting plate 20 can be raised and lowered on the sling body 10. The circular connecting plate 20 descends, so that the guide hopper 30 is placed below the sling body 10 to wrap and guide the container body 40.
[0019] In this embodiment, when the container body 40 is hoisted, the hoist body 10 is first placed above the container body 40 by the crane, and then the guide hopper 30 is lowered to the bottom of the hoist body 10 by the driving assembly 50 until the return connecting plate 20 is placed below the hoist body 10, and then the hoist body 10 is lowered, so that the guide hopper 30 is displaced toward the container body 40, until the container body 40 is corrected by the guide hopper 30, so that the container body 40 is aligned with the hoist body 10, and when the hoist body 10 and the top of the container body 40 are in contact with each other, the hoist body 10 locks the container body 40, and then the crane drives the hoist body 10 to lift, completing the hoisting process of the container body 40; Of course, during the hoisting process of the container body 40, the guide hopper 30 is not reset, and the guide hopper 30 is wrapped around the side wall of the container body 40 for protection; The container body 40 is wrapped and guided by the guide hopper 30 to ensure that the container body 40 is accurately aligned with the spreader body 10, thereby reducing the error in the lifting process, improving the safety of the lifting operation, and reducing the adjustment and alignment time in the traditional lifting process, thereby improving the lifting efficiency of the container body 40; During the hoisting process, the guide hopper 30 does not reset, and continues to wrap around the side wall of the container body 40, providing additional protection for the container body 40 and reducing possible collisions and damages during the hoisting process; Through the lifting mechanism of the integrated driving assembly 50 and the circular connecting plate 20, the lifting operation process is simplified, the operating difficulty is reduced, and the operator can complete the lifting operation of the container body 40 more conveniently.
[0020] Specifically, the guide hopper 30 is provided with a first port 31 and a second port 32, and the return-shaped connecting plate 20 is connected to the second port 32; The first port 31 and the second port 32 are similar in shape.

The area of the first port 31 is larger than the cross section of the container body 40 , so that the container body 40 enters the inner cavity of the guide hopper 30 through the first port 31 .
[0021] In this embodiment, when corrective guidance is performed, the container body 40 first enters the inner cavity of the guide hopper 30 through the first port 31. At this time, the container body 40 contacts the inclined surface inside the guide hopper 30. When the guide hopper 30 descends, the sling body 10 is guided and corrected through the inclined surface inside the guide hopper 30, so that the sling body 10 is aligned with the container body 40 for the lifting process.
