An electric telescopic rod 23 is rotatably installed on the end of the hinge seat 22 away from the baffle 21, and a hinge seat 25 is rotatably installed on the end of the electric telescopic rod 23 away from the hinge seat 1 22. An insert plate 26 is fixedly installed on the end of the hinge seat 25 away from the electric telescopic rod 23, and a crossbeam 24 is slidably installed on the outside of the insert plate 26, so that the device can be adjusted to be telescopic.

[0032] Two cross beams 24 are provided, and baffles 21 are fixedly installed at one end of the two cross beams 24 away from the plug plate 26. Two electric telescopic rods 23 are provided to limit the telescopic movement of the device. Embodiment 2

[0033] See also Figure 6 In combination with the first embodiment, it is further obtained that the telescopic component 32 includes a limit frame 322, the limit frame 322 is fixedly installed on the right side of the base 1, a telescopic frame 323 is slidably installed inside the limit frame 322, a fixed wheel 324 is rotatably installed at the bottom of the telescopic frame 323, and a spring pin 321 is slidably installed on the top of the telescopic frame 323, which can make the chassis of the device telescopic.

[0034] There are two telescopic frames 323 and two fixed wheels 324, and the two fixed wheels 324 are rotatably mounted on the right bottom of the telescopic frame 323 to limit the telescopic operation of the chassis.

[0035] The supporting assembly 31 includes a rectangular block 311, which is fixedly mounted on the front side of the limit frame 322. A rotating plate 312 is rotatably mounted on the bottom side of the inner part of the rectangular block 311. A changing wheel 318 is rotatably mounted on the end of the rotating plate 312 away from the rectangular block 311. A connecting rod 1 313 is rotatably mounted on the top of the rotating plate 312. A connecting rod 2 315 is rotatably mounted on the end of the connecting rod 1 313 away from the rotating plate 312. A hinge seat 316 is rotatably mounted on the end of the connecting rod 2 315 away from the connecting rod 1 313. A bolt 314 is threadedly mounted on the outer side of the connecting rod 2 315. A limiting block 317 is slidably mounted on the outer side of the connecting rod 1 313, which can make the chassis more stable through adjustment.

[0036] A threaded hole is provided on the outer side of the limit block 317, two hinge seats 316 are provided, and the two hinge seats 316 are fixedly installed with a limit frame 322 at one end away from the connecting rod 2 315 to limit the adjustment of the chassis.

[0037] In actual operation, when the device is used, the rotating plate 312 is manually rotated in advance. When the rotating plate 312 is rotated, the connecting rod 1 313 is rotated by the rotating installation between the connecting rod 1 313. When the connecting rod 1 313 is rotated, the connecting rod 2 315 is rotated by the rotating installation between the connecting rod 2 315. At this time, the rotating plate 312 is rotated to form a 90-degree angle with the limiting frame 322, and the connecting rod 1 313 and the connecting rod 2 315 are horizontal by the rotating installation. When the connecting rod 1 313 and the connecting rod 2 315 are horizontal, the limiting block 317 is manually slid. When the sliding limiting block 317 is When the block 317 is in contact with the bolt 314 on the outside of the second connecting rod 315, the bolt 314 is manually rotated when in contact with the bolt 314, so that the direction-changing wheel 318 can be unfolded, so that the chassis is more stable during movement. At this time, the spring pin 321 is manually pulled out, and when the spring pin 321 is pulled out, the spring pin 321 is separated from the limit frame 322, so that the telescopic frame 323 is telescoped. When the telescopic frame 323 is telescoped to the moving position, the bottom support area can be increased, so that when the cargo is heavy or the weight of the truck is irregular, the chassis can be ensured not to shake.

[0038] When the bottom adjustment is completed, the motor on the left side of the base 1 is energized manually. When the motor is energized, the rotating shaft is rotated by fixing it with the rotating shaft. When the rotating shaft rotates, the gear is rotated by fixing it with the gear. When the gear rotates, the gear is rotated by fixing it with the toothed disc. When the toothed disc rotates, the lifting screw is rotated by threading it with the lifting screw. When the lifting screw rotates, the baffle 21 is raised by threading it with the baffle 21. In this way, when the baffle 21 rises, it drives the plug plate 26 to rise. When it rises to the same height as the platform, the electric telescopic rod 23 is energized again. When the electric telescopic rod 23 is energized, it is rotatably installed with the hinge seat 25. When the hinge seat 25 and the electric telescopic rod 23 are rotatably installed, the plug plate 26 can be driven to extend and retract. In this way, the goods can be loaded and unloaded by extending and retracting the plug plate 26.
