A rotating block 42 is rotatably connected to the inner side of the mounting frame 41. Mounting cylinders 43 are fixedly installed on the opposite sides of the two rotating blocks 42. A rectangular plate 44 is slidably installed on the inner side of the mounting cylinder 43. A connecting column 45 extending to the outside of the mounting cylinder 43 is fixedly installed on one side of the rectangular plate 44. A rectangular block 46 that fits the U-shaped groove 3 is fixedly installed on one end of the connecting column 45. A telescopic spring 47 fixedly connected to the inner wall of the mounting cylinder 43 is fixedly installed on one side of the rectangular plate 44. The elastic coefficient of the telescopic spring 47 can be set according to demand.

[0027] A rotating shaft is fixedly installed on the inner side of the mounting frame 41, and the rotating block 42 is rotatably connected to the mounting frame 41 through the rotating shaft, allowing the rotating block 42 to rotate within a certain range. A rectangular hole that is compatible with the connecting column 45 is opened on the inner wall of the mounting tube 43 close to the rectangular block 46.

[0028] The fixing mechanism 5 includes a card rod 51. Two card rods 51 are slidably installed on the left and right sides of the tray body 1 and extend to the inner side of the U-shaped groove 3. Through holes connected to the U-shaped groove 3 are opened on the left and right sides of the tray body 1. The size of the through hole is adapted to the card rod 51. A handle 52 is fixedly installed on one end of the card rod 51 located on the outside of the tray body 1.

When the limiting mechanism 4 needs to be used, the handle 52 is used to pull the card rod 51 outward, and then the angle of the mounting tube 43 is adjusted to extend it above the pallet body 1 under the support of the rotating block 42. After the rectangular block 46 is separated from the U-shaped groove 3, the limit on it is released, and then the tension of the telescopic spring 47 pushes the rectangular plate 44 to make the connecting column 45 extend outward. After adjusting the angle of the rotating block 42, the handle 52 is released. Under the tension of the limit spring 55, the mounting frame 54 and the stabilizing rod 53 push the clamping rod 51 to reset. The clamping rod 51 extends to the inner side of the rotating block 42 and fixes it. In this way, the mounting cylinder 43, the connecting column 45 and the rectangular block 46 limit and fix the goods, achieving the purpose of the limit function and solving the problem that there is no certain limit function. During use, the goods on the plastic pallet are prone to fall off, resulting in damage to the goods and the inability to transport the goods smoothly, which reduces the practicality of the plastic pallet.
