A second guide sliding hole 8011 is provided on one side of the outer tube 801 close to the second limiting rod 803 to accommodate the second limiting rod 803 sliding up and down. The second limiting rod 803 passes through the second guide sliding hole 8011 and extends to the outside of the outer tube 801. After that, it is threadedly connected with a fastener 804. The fastener 804 and the second limiting rod 803 can be specifically a threaded connection. By loosening the fastener 804, the extension length of the inner rod 802 can be adjusted, so that the bottom end of the second support seat 5 is in contact with the bottom end of the interior of the car, providing support for one end of the second support seat 5 to improve its stability. Then, the fastener 804 can be tightened to fix it. A universal wheel with a braking mechanism is also installed at the bottom end of the second support seat 5 to facilitate the adjustment of the position of the second support seat 5. In this embodiment, the two outer tubes 801 are fixed on both sides of the second support seat 5 in the width direction. When the second support seat 5 is retracted to the top of the first support seat 1, the telescopic support leg 8 can be extended to the bottom of the first support seat 1 to reduce space occupancy.

[0023] A support rod 301 is horizontally arranged at the bottom of one end of the movable slide groove 3 near the unloading mechanism 7. The support rod 301 is located below the first support seat 1, and the length of the support rod 301 is not less than the width of the first support seat 1. A limiting sliding hole 3011 with an opening at one end is arranged on the support rod 301 along its length direction. A limiting sliding rod 9 is arranged on one side of the bottom end of the first support seat 1 near the limiting sliding hole 3011. The limiting sliding rod 9 can rotate inside the limiting sliding hole 3011. After the limiting sliding rod 9 passes through the limiting sliding hole 3011, a locking member 10 is threadedly connected. In this embodiment, the limiting sliding hole 3011 is provided with one, refer to the attached Figure 6-7 After the first support seat 1 is slid horizontally onto the support rod 301, the limiting slide rod 9 is inserted into the limiting slide hole 3011. When the first support seat 1 is separated from the movable slide groove 3, the first support seat 1 can be rotated to the side close to the unloading mechanism 7, and then the locking piece 10 can be tightened to fix it. At this time, the objects sliding off the unloading mechanism 7 can also fall directly onto the first conveyor belt 2.

[0024] In some embodiments, the limit slide rod 9 can also be detachably installed at the bottom end of the first support seat 1. The two support rods 301 are both penetrated by limit slide holes 3011. By adjusting the position of the limit slide rod 9, it can be inserted into different limit slide holes 3011, and then the first support seat 1 can be rotated to different directions.

[0025] Working principle: When working, the movable rod 403 is pushed to slide horizontally through the linear drive mechanism 404, and then the first connecting rod 401 and the second connecting rod 402 on both sides can be synchronously driven to rotate, so that the distance between the ends of the two is expanded or reduced, and then the second support seat 5 is pushed up or down, and the second support seat 5 is adjusted to be inserted into the interior of the carriage. At the same time, the length of the telescopic support leg 8 is adjusted so that the bottom end of the telescopic support leg 8 is in contact with the bottom end of the interior of the carriage, providing support for the second support seat 5, improving its stability, and placing the goods inside the carriage on the top of the second conveyor belt 6 The second conveyor belt 6 transports the goods to one end, and then slides to the top of the first conveyor belt 2 through the unloading mechanism 7 to realize the downward transportation of the goods. When the first support seat 1 is fixed, the movable slide groove 3 is pushed to slide horizontally relative to the first support seat 1, and the depth of the second conveyor belt 6 inserted into the car can be adjusted. When the direction of goods transportation needs to be changed, the first support seat 1 can be slid horizontally to the end of the support rod 301, and the limiting slide rod 9 is inserted into one end of the limiting slide hole 3011. After the first support seat 1 is rotated 90°, it can be locked by the locking member 10 to meet different needs.
