[0067] Example 6: Figure 12As shown, the difference from the third embodiment is that the hook 25 has an inclined surface to facilitate the hook 25 to squeeze into the socket. After the hook 25 passes through the socket, it is buckled on the edge of the socket. The side strips 3 in the second embodiment are also provided on the left and right sides of the plastic base plate 1, and separators 31 are provided on the side strips 3 on both sides.

[0068] Example 7, as Figures 13 to 15 As shown, the difference from the first embodiment is that a separator 31 is provided. The guide slide 2 is provided at the front end 13, left side 14, rear end 15, and right side 16 to form a cavity 18. The side strips 3 on the left and right sides 15 and 16 are provided with separators 31 that are integrally formed with the side strips 3 and extend vertically. The left and right sides 15 and 16 are provided with a snap groove 17, and the side strips 3 are provided with a clip groove 32. The clip groove 32 is provided with a protrusion 33 that snaps into the snap groove 17. The upper end surfaces of the left and right sides 15 and 16 have one snap groove 17, and the lower end surfaces of the left and right sides 15 and 16 have two snap grooves 17. There are three protrusions 33 corresponding to each snap groove 17.

[0069] Example eight, as Figures 16 to 18 As shown, the difference from Example 1 is that the structure of the first plug-in portion 22 is different from that of the second plug-in portion 11. Specifically, the first plug-in portion 22 includes positioning and mounting grooves on the left and right sides of the bottom end of the guide slide 2, and the second plug-in portion 11 includes a positioning block that can be inserted into the positioning and mounting groove. The first plug-in portion 22 also includes an inserting edge at the bottom end of the guide slide 2 and extending vertically.

Two support buckles 72 are respectively provided on the left and right sides of the annular frame to support the annular frame. A plurality of parallel and spaced longitudinal beams 5 are provided on the bottom frame 4, and the longitudinal beams 5 extend in the front and rear directions. The front and rear sides of the bottom frame 4 are respectively provided with connecting strips 6. The bottom frame 4 is provided with a plurality of parallel bottom plates 1 supported by the longitudinal beams 5. The two ends of the bottom plate 1 are respectively inserted into the front and rear connecting strips 6. The two ends of the connecting strip 6 have slots for the two ends of the bottom plate 1 (the front end head 13 and the rear end head 14) to be inserted. The height of the longitudinal beam 5 gradually decreases from the rear end to the front end, so that the bottom plate 1 and the guide slide plate 2 are low in the front and high in the rear, and the material can slide by gravity. Guardrails 7 are provided on the left and right sides of the bottom frame 4, and both ends of the guardrails 7 extend downward and protrude from the bottom frame 4 to form positioning ends 71. The two positioning ends 71 ​​on the same side are respectively pressed against the support buckles 72 to position the bottom frame 4 in the front and rear directions. The two ends of the guardrails 7 are respectively blocked against the front side of the front support buckle 72 and the rear side of the rear support buckle 72, so that the bottom frame 4 can be positioned front and back.
