[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] In order to improve the stability of the container during lifting, refer to Figure 1 、 Figure 2 and Figure 3As shown, it includes a supporting frame 1, two positioning frames 2, two clamping frames, a first driving assembly and a second driving assembly. The two positioning frames 2 are respectively arranged on the left and right sides of the supporting frame 1. A limiting area for fixing the container is formed between the two positioning frames 2. The two clamping frames are arranged in the limiting area to further clamp the container. Among them, the two positioning frames 2 change the size of the limiting area through the first driving assembly, and the two clamping frames are switched and closed by the second driving assembly to achieve clamping and fixing of the container. The first motor 5 drives the first gear 6 to rotate, and the first gear 6 is connected to the second gear 7 through the first gear 6. They mesh with each other, driving the second gear 7 to rotate, driving the first rotating shaft 4 to rotate, so that the two positioning frames 2 are close to each other and are sleeved on the container, fixing the container in the limited area. As the second motor 9 drives the third gear 11 to rotate, the two third gears 11 are in meshing with each other, causing the second rotating shaft 10 to rotate, so that the two clamping frames 3 are close to each other, clamping the container, further improving the fixation of the container, and with the stretching of the telescopic cylinder 13, the two clamping frames 3 are fixed, which is stable, has a simple overall structure, is easy to use, and can increase the clamping force of the container.

[0021] In order to further improve the clamping and fixing of the container, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the left and right ends of the support frame 1 are both plugged with a first rotating shaft 4, and a first motor 5 is provided on the upper surface of the support frame 1. The power output end of the first motor 5 is connected to a first gear 6. As the first motor 5 drives the first gear 6 to rotate, the first gear 6 and the second gear 7 engage with each other, thereby driving the rotation of the first rotating shaft 4. A second gear 7 is provided at one end of the first rotating shaft 4, and the second gear 7 engages with the first gear 6. The second gear 7 is sleeved on the first rotating shaft 4, so when the second gear 7 rotates, the first rotating shaft 4 rotates accordingly. A notch is provided in the center of the upper surface of the positioning frame 2, and the two ends of the rotating shaft are respectively connected to the inner wall of the notch. As the first rotating shaft 4 rotates, the two positioning frames 2 can be driven to rotate, so that the two positioning frames 2 are moved closer to or away from each other. The first motor 5, the first gear 6, the second gear 7 and the first rotating shaft 4 are all provided in pairs. The support frame 1 is provided with a plurality of fixed plates 8 on the lower surface, and a cavity is separated between each two adjacent fixed plates 8. The second drive assembly includes a second motor 9 provided on the outside of the fixed plate 8. There are four fixed plates 8 in total, and at least two non-adjacent fixed plates 8 are provided with a second motor 9 on the outside. The clamping frame is provided in the cavity through a second rotating shaft 10. The power output end of the second motor 9 is connected to the second rotating shaft 10. Two third gears 11 are provided on the side of the fixed plate 8 away from the motor. The two third gears 11 are respectively connected to the second rotating shaft 10. Two second rotating shafts 10 are inserted into each cavity, and the two third gears 11 are respectively sleeved on the second rotating shaft 10. The second motor 9 is connected to one of the second rotating shafts 10. When the second motor 9 drives the second rotating shaft 10 to rotate, it can drive one of the third gears 11 to rotate. Through the engagement of the two third gears 11, the two clamping frames 3 are driven to rotate, so that they are closer to each other or farther away from each other. Two connecting rods 12 are connected between the two clamping frames, and a telescopic cylinder 13 is provided between the two connecting rods 12. Both connecting rods 12 are provided with connecting buckles. The telescopic cylinder 13 is installed between the two connecting buckles. The power output end of the telescopic cylinder 13 is connected to one of the connecting buckles. When the power output end of the telescopic cylinder 13 is pulled, the two connecting rods 12 can be driven to approach each other, so that the two clamping frames 3 are approached to each other, thereby improving the stability of the clamping frame 3 after clamping the container.

[0022] When in use, the first motor 5 first drives the first gear 6 to rotate, and the first gear 6 and the second gear 7 are engaged with each other, driving the second gear 7 to rotate, driving the first rotating shaft 4 to rotate, so that the two positioning frames 2 are close to each other and are sleeved on the container to fix the container in the limited area. As the second motor 9 drives the third gear 11 to rotate, the two third gears 11 are engaged with each other, causing the second rotating shaft 10 to rotate, so that the two clamping frames 3 are close to each other, clamping the container, further improving the fixation of the container, and the two clamping frames 3 are fixed as the telescopic cylinder 13 is stretched.
