A telescopic folding frame 4 is assembled and connected inside the base frame 1. A support platform 5 is fixedly installed on the top of the folding frame 4. A hidden groove 6 is opened on the top of the support platform 5, and a guide roller 7 is installed inside the hidden groove 6. Mounting grooves 8 are opened at both ends of the hidden groove 6. Mounting shafts 9, rotatably connected to the inner side of the mounting grooves 8, are fixedly installed at both ends of the guide roller 7. A rectangular groove 10 is opened on the top of the support platform 5, and a locking seat 11 is slidably installed inside the rectangular groove 10. A first spring 12, supporting and connected to the locking seat 11, is fixedly connected to the inner side of the rectangular groove 10. A limit lock groove 13 is opened on the other side of the locking seat 11. A gear mechanism 14 is fixedly installed at one end of one set of mounting shafts 9. The top of the locking seat 11... A control lever 15 is fixedly installed. A limit groove 16 is opened on both sides of the rectangular groove 10. A limit member 17 that passes through the limit groove 16 is fixedly installed on both sides of the locking seat 11. A fence 18 is fixedly installed around the perimeter of the support platform 5. A railing 19 is rotatably connected to one side of the edge of the fence 18. A connecting seat 20 is fixedly installed on one side of the edge of the railing 19. A circular groove 21 is opened on the top of the connecting seat 20. A telescopic shaft 22 is set inside the circular groove 21. A second spring 23 that supports and connects to the telescopic shaft 22 is fixedly connected to the bottom side of the circular groove 21. A connector 24 is fixedly installed on the top of the telescopic shaft 22. A plug 25 is fixedly installed on the bottom of the connector 24. A fixing seat 26 is fixedly installed on one side of the fence 18. A slot 27 is opened on the top of the fixing seat 26.

[0025] Furthermore, the gear mechanism 14 at one end of the mounting shaft 9 is engaged with the limiting locking groove 13 inside the locking seat 11. After the material is placed on the guide roller 7, when the locking seat 11 is engaged with the gear mechanism 14 at one end of the mounting shaft 9 through the limiting locking groove 13, the material is in a limited support state through the guide roller 7.

[0026] Furthermore, when the locking seat 11 is controlled to slide inside the rectangular groove 10 by controlling the lever 15, the locking seat 11 is separated from the gear mechanism 14 and the material on the guide roller 7 is rotated and guided by the guide roller 7.

[0027] Furthermore, when the locking seat 11 slides inside the rectangular groove 10, the locking seat 11 is engaged with the limiting groove 16 by two sets of limiting members 17.

[0028] Furthermore, the plug 25 at the bottom of the connector 24 engages with the slot 27 inside the fixing seat 26 for a limiting insertion. After the railing 19 is flipped and aligned with one side of the fence 18, the plug 25 at the bottom of the connector 24 is inserted into the fixing seat 26, and the railing 19 and the fence 18 are in a closed and fixed state.

[0029] Working principle of the invention:

[0030] The surface of the support platform 5 is equipped with guide rollers 7 through the hidden groove 6. In the default state, the limiting lock groove 13 inside the locking seat 11 can be elastically supported by the first spring 12 inside the rectangular groove 10 and externally limited by the gear mechanism 14. At this time, one set of guide rollers 7 can be fixed and limited. After the material is placed on the support platform 5, the folding frame 4 can be raised to a specific height under the drive of the cylinder assembly. When unloading and moving the material, the control lever 15 can be moved to one side to make the locking seat 11 slide inside the rectangular groove 10 and separate from the gear mechanism 14. At this time, the guide roller 7 can be unlocked, and the material on multiple sets of guide rollers 7 can be rotated and moved by multiple sets of guide rollers 7 without manual force for unloading and handling, thereby improving unloading efficiency.
