[0029] In the case, the connecting mode between the rotator 20 and the container spreader 10 is prior art, that is, the container spreader 10 can be lifted by the hoisting rotator 20, and the container spreader 10 can be rotated by the rotator 20, and the specific structure is not described in detail here.

[0030]

[0031] ​In this embodiment, before the container spreader 10 rotates, two sets of elastic winding assemblies 30 are placed on the limiting rotating plate 21, and the steel cable 40 is placed between the limiting connecting plate 11 and the limiting rotating plate 21, so that the steel cable 40 is wound around the elastic winding assembly 30. When the rotator 20 drives the container spreader 10 to rotate, the steel cable 40 is stretched, so that the wound steel cable 40 is detached from the elastic winding assembly 30, that is, the length of the steel cable 40 between the limiting connecting plate 11 and the limiting rotating plate 21 becomes longer. When the length of the steel cable 40 between the limiting connecting plate 11 and the limiting rotating plate 21 no longer becomes longer, the maximum rotation angle of the container spreader 10 is reached, and at the same time, the steel cable 40 is firmly connected between the limiting connecting plate 11 and the limiting rotating plate 21.

[0032] By matching the positions of two sets of limiting rotating plates 21 symmetrically arranged on the rotating frame 25 of the rotator 20 and two sets of limiting connecting plates 11 symmetrically arranged on the connecting frame 13 of the container spreader 10, and by cooperating with the steel cable 40 between the elastic winding assembly 30 on the limiting rotating plate 21 and the limiting connecting plate 11, precise control of the rotation angle of the container spreader 10 is achieved, preventing safety accidents caused by excessive rotation and greatly improving the safety and reliability of operation.

[0039] Specifically, the two ends of the winding wheel 33 are provided with support rods 36, and the two groups of support rods 36 are rotationally arranged on the two groups of support plates 32.

[0040] Specifically, the mounting plate 31 is also symmetrically provided with two groups of positioning plates 34, and the two groups of support plates 32 are arranged between the two groups of positioning plates 34.

[0041] The support rod 36 is also rotationally arranged on the positioning plate 34.

[0042] Specifically, the outer wall of the support rod 36 is provided with a movable plate 35, a torsional spring 37 is arranged between the movable plate 35 and the positioning plate 34, and the torsional spring 37 is sleeved on the outer wall of the support rod 36.

[0043] In the embodiment, when the steel cable 40 is separated from the winding wheel 33, the winding wheel 33 is in a rotating state, so that the support rod 36 rotates to drive the movable plate 35 to rotate, the torsional spring 37 is deformed through the connection between the movable plate 35 and the torsional spring 37, and when the container spreader 10 is reset, the torsional spring 37 is reset to reversely drive the winding wheel 33 to rotate to wind the steel cable 40.

[0044] Specifically, the limiting rotation plate 21 is provided with a guide block 22, the guide block 22 is fixedly connected with the limiting rotation plate 21, and the guide block 22 is arranged directly below the winding wheel 33.
