The arc grooves 7 are respectively opened on the two support plates 6, and the sliding rod 8 is located between the two arc grooves 7, so that the sliding rod 8 can slide up and down and rotate along the arc groove 7. The turntable 9 is fixedly mounted on the sliding rod 8 and is located between the two support plates 6, so that it can slide up and down in the arc groove 7 following the sliding rod 8. A plurality of teeth 10 are integrally formed on the outer wall of the turntable 9, and the turntable 9 follows the sliding rod 8 to slide to the bottom end of the arc groove 7, so that the teeth 10 can engage with the rack 5. The turntable 9 follows the sliding rod 8 to slide upward from the bottom end of the arc groove 7, so that the teeth 10 can be disengaged from the rack 5.

[0026] In one embodiment, specifically, a limit block 11 is provided at each end of the sliding rod 8, and the limit block 11 abuts against the outer wall of the support plate 6. The limit blocks 11 are fixedly installed at the two ends of the sliding rod 8. When the sliding rod 8 slides in the arc groove 7, the limit block 11 abuts against the outer wall of the support plate 6, which can prevent the sliding rod 8 from swinging.

[0027] Among them, the rotating wheel 9 is provided with a connecting rod 12, and the connecting rod 12 is provided with a handle 13. The connecting rod 12 is fixedly installed on the outer wall of the rotating wheel 9, and the handle 13 is screwed to the end of the connecting rod 12. Pressing the handle 13 downward can make the rotating wheel 9 rotate in the arc groove 7 and move to the bottom end of the arc groove 7, so that the teeth 10 can engage with the rack 5. Continuing to press the handle 13 downward can make the teeth 10 push the rack 5 to move upward, and can make the lifting rod 3 drive the mounting seat 4 to move upward.

[0028] On the basis of the above embodiment, specifically, an extension rod 14 is screwed onto the handle 13, and the extension rod 14 is screwed onto the outer wall of the handle 13. Rotating the extension rod 14 can move the extension rod 14 toward the end of the handle 13, which can make pressing more labor-saving.

[0029] More specifically, the support rod 1 is provided with a movable cavity 15, and a top block 16 is provided in the movable cavity 15. The support rod 1 is provided with a locking bolt 17, one end of the locking bolt 17 is rotatably connected to the top block 16, and a handle 18 is provided at the end of the locking bolt 17 and located on the outside of the support plate 6.

Rotating the locking bolt 17 can move the top block 16, and can cause the top block 16 and the rack 5 to be stuck with each other, so that the lifting rod 3 and the support rod 1 can be fixed to each other. The handle 18 is fixedly installed on the end of the locking bolt 17 and is located on the outside of the support rod 1, so that the locking bolt 17 can be rotated conveniently by the handle 18.

[0030] Furthermore, a pressure plate 19 is provided at the bottom of the support rod 1, which is fixedly installed at the bottom of the support rod 1, thereby increasing the contact area between the support rod 1 and the ground, preventing the bottom of the support rod 1 from sliding on the ground, and making the device more stable in supporting the trailer.

[0031] On the basis of the above embodiment, more specifically, a plurality of grooves 20 are provided at the bottom of the pressure plate 19. The plurality of grooves 20 are opened at the bottom of the pressure plate 19, which can increase the friction between the pressure plate 19 and the ground, further prevent the pressure plate 19 from sliding on the ground, and further increase the stability of the device in supporting the trailer.

[0032] When in use, multiple devices are pre-fixed on the trailer through the mounting base 4. When the ground where the trailer is parked is uneven, the trailer becomes skewed. At this time, according to the skewed position of the trailer, the corresponding locking bolt 17 of the device is screwed. As the locking bolt 17 is screwed, the top block 16 moves out of the rack 5. Then, the handle 13 is lifted upward. As the handle 13 is lifted, the connecting rod 12 drives the sliding rod 8 on the rotating wheel 9 to move upward in the arc groove 7. At the same time, the rotating wheel 9 drives the teeth 10 to separate from the rack 5. Then, the support rod 1 falls along the lifting rod 3. Then, the bottom of the pressure plate 19 contacts the ground. Then, the extension rod 14 is rotated and pressed downward. The extension rod 14 drives the handle 13 and the connecting rod 12 to move downward. At the same time, the connecting rod 12 drives the sliding rod 8 on the rotating wheel 9 to the bottom end of the arc groove 7. When the sliding rod 8 moves to the bottom end of the arc groove 7, the teeth 10 on the rotating wheel 9 engage with the rack 5. As the extension rod 14 is continued to be pressed, the teeth 10 push the rack 5 upward. At the same time, the rack 5 drives the lifting rod 3 to move upward, and the lifting rod 3 drives the mounting seat 4 and the trailer to rise. Then, the extension rod 14 is lifted, the teeth 10 are separated from the rack 5. Then, the extension rod 14 is pressed again, the teeth 10 engage with the rack 5 again and push the lifting rod 3 upward. In this way, the lifting rod 3 drives the mounting seat 4 to gradually lift the skewed position of the trailer. When the skewed position of the trailer is in a relatively horizontal state, the locking bolt 17 of the corresponding device is screwed, and the top block 16 moves in the active cavity 15. Then, the top block 16 and the rack 5 are stuck with each other, and the lifting rod 3 and the support rod 1 are relatively fixed. Then, the extension rod 14 can be released.
