The first limiting frame 35 and the second limiting frame 36 are transversely arranged in parallel in the groove of the support 31, the first limiting frame 35 and the protrusion of the radial middle part of the second limiting frame 36 are connected with the support 31 through pin shafts, the radial bottom end of the first limiting frame 35 is connected with the middle connecting mechanism 32 through pin shafts, the radial upper end of the second limiting frame 36 is connected with a second reset spring 307, and the other end of the second reset spring 307 is connected with a second reset spring pin shaft 304 at the radial upper end of the support 31. The bracket 31 is further provided with a locking arm 37, one end of the locking arm 37 is connected with the bracket 31 through a pin shaft, and the arm end in a pincer shape is arranged at the upper end or the lower end of the radial middle protruding part of the second limiting frame 36. When the arm end of the clamp-shaped locking arm 37 is arranged at the upper end of the middle bulge of the second limiting frame 36, the second limiting frame 36 can be pushed to move, and when the arm end of the clamp-shaped locking arm is arranged at the lower end of the middle bulge of the second limiting frame 36, the second limiting frame 36 cannot be pushed to move.

One end of the bracket 31 is provided with a cylindrical steering cam 34, the steering cam 34 is connected with the intermediate connecting mechanism 32 through a pin shaft, and one end of the cross section of the steering cam 34 is connected with a control handle 33 outside the bracket 31. A reset guide rod 38 is fixed near the fixed ends of the operating handle 33 and the bracket 31, the other end of the reset guide rod 38 is fixed on the outer side of the bracket 31, and a first reset spring 39 is fixedly sleeved on the reset guide rod 38. And a standard container lock 7 is also arranged on the frame 1 near the fixed locking device 3.

In operation, as shown in fig. 2, the operator operates the operating handle 33 to rotate 180 degrees clockwise, the operating handle 33 drives the steering cam 34 to move, and the steering cam 34 drives the intermediate connection mechanism 32 to move together; the intermediate connection mechanism 32 drives the locking arm 37 and the first limiting frame 35 to move together, and pushes the first limiting frame 35 to achieve a limiting locking function when the intermediate connection mechanism 32 is vertical. If the second limiting frame 36 is required to perform the limiting and locking function, the arm end of the locking arm 37 is placed at the upper end of the middle protrusion of the second limiting frame 36, and the limiting and locking function is realized when the middle connecting mechanism 32 drives the locking arm 37 to push the second limiting frame 36 to be perpendicular to the middle connecting mechanism 32 in the moving process.
