The two mechanical claws 23 cooperate with each other to clamp the transfer tray. A control motor 26 is also installed at the bottom center of the carrying frame 21. The output shaft of the control motor 26 extends into the carrying frame 21 and is installed with a linkage gear 25. Racks 24 are arranged on the inner sides close to the two extension arms 22, and the two racks 24 are meshed with the linkage gear 25.

[0026] Specifically, with the cooperation of the control motor 26, the linkage gear 25 can be easily pushed to rotate. Due to the meshing action of the linkage gear 25 and the rack 24, the rack 24 and the extension arm 22 can be pushed to slide in the supporting frame 21. A mechanical claw 23 is also installed on the outer end of the extension arm 22. When the extension arm 22 slides, the mechanical claw 23 can be operated to clamp and fix the pallet, thereby facilitating the transfer of the pallet and facilitating packaging and transportation.

[0027] like Figure 3 , Figure 4 As shown, the retracting and unfolding mechanism includes a rotating plate 11 arranged at the center of the bearing part 1, and the two ends of the rotating plate 11 are respectively connected to the two bearing frames 21 through connecting rods 12, which are used to adjust the distance between the two bearing frames 21. A working motor 14 is also installed at the top center of the bearing part 1, and the output shaft of the working motor 14 extends into the bearing part 1 and is installed at the center of the rotating plate 11. A hinge seat 13 is also provided on the side of the bearing frame 21, and the connecting rod 12 is installed on the hinge seat 13;

[0028] Specifically, in order to adapt to pallets of different sizes, a rotating plate 11 is further provided in the load-bearing portion 1. With the cooperation of the working motor 14, the rotating plate 11 can be pushed to rotate. The ends of the rotating plate 11 are respectively connected to the two load-bearing frames 21 through connecting rods 12. When the rotating plate 11 rotates, the connecting rods 12 can be used to push the load-bearing frames 21 to slide, and sliding grooves 15 are also provided on the front and rear side edges of the load-bearing portion 1. The length of the load-bearing frame 21 is greater than the width of the load-bearing portion 1. The load-bearing frame 21 is slidably set in the sliding groove 15, and the two ends of the load-bearing frame 21 are respectively set beyond the sliding groove 15, so that the distance between the two load-bearing frames 21 can be conveniently adjusted to facilitate the coordination of pallets of different sizes.

[0029] like Figure 1 , Figure 2 As shown, two guide bars 3 are further arranged above the load-bearing portion 1, a plurality of reinforcing ribs 32 are arranged between the two guide bars 3, and two guide frames 31 are installed on the top of the load-bearing portion 1, and the guide frames 31 are slidably installed in the guide bars 3. In addition, the guide frames 31 installed on the load-bearing portion 1 can be slidably installed in the guide bars 3.

[0033] When in use, first control the bearing part 1 to slide along the guide rail 3 and move to the top of the conveying frame to facilitate alignment with the pallet, then start the control motor 26, which can easily drive the linkage gear 25 to rotate. Due to the meshing action of the linkage gear 25 and the rack 24, the rack 24 and the extension arm 22 can be driven to slide in the bearing frame 21. A mechanical claw 23 is also installed on the outer end of the extension arm 22. When the extension arm 22 slides, the mechanical claw 23 can be operated to clamp and fix the pallet, so that the pallet can be conveniently transported without being limited by the grid structure of the pallet. It is more practical and convenient for packaging and transportation.

[0034] In addition, in order to adapt to pallets of different sizes, a rotating plate 11 is further provided in the load-bearing portion 1. With the cooperation of the working motor 14, the rotating plate 11 can be pushed to rotate.
