[0027] As mentioned above, when using the scanning frame, adjusting member and side frame provided by the utility model, the two side frames are connected by the adjusting member, and the adjusting member is four cross bars 17, and the two ends of the four cross bars 17 are respectively installed on the four intersection points on the two side frames. When the cross bars 17 move on the intersection points, the distance between the two side frames can be adjusted, and the length of the scanning frame can be adjusted.

[0028] In the present utility model, combined with Figure 1-3As shown, the side frame of this embodiment includes two vertical rods 6 and two longitudinal rods 8 in a criss-cross structure, and connecting parts are installed between adjacent vertical rods and longitudinal rods 8. A first connecting ring 7 is installed on the top of each connecting part, and one end of the cross rod 17 slides through the corresponding first connecting ring 7. The first connecting ring 7 is screwed with a second locking bolt 16 that abuts against the cross rod 17.

[0029] Combination Figure 3 As shown, the connecting member includes a sleeve 10 and a second connecting ring 11 arranged on the outside of the sleeve 10, the sleeve 10 is transversely penetrated and sleeved on the corresponding longitudinal rod 8, the second connecting ring 11 is longitudinally penetrated and sleeved on the corresponding vertical rod 6, and the second connecting ring 11 is threaded with a first locking bolt 5 that abuts against the vertical rod 6.

[0030] As mentioned above, when using the side frame provided by the utility model, the two vertical rods 6 and the two longitudinal rods 8 form a tic-tac-toe structure through four connecting parts. The connecting part can slide on the longitudinal rod 8 through the sleeve 10, and the connecting part can slide on the cross rod 17 through the first connecting ring 7. At the same time, the connecting part slides on the vertical rod 6 through the second connecting ring 11, thereby forming a scanning frame with adjustable size. The frame can be adjusted according to the size and layout of different plant factories to ensure adaptation to various environments.

[0031] In the present utility model, combined with Figure 1-2 As shown, a movable seat 1 is also installed below one of the cross bars 17 in this embodiment.

[0032] As mentioned above, when using the mobile seat 1 provided by the utility model, a universal wheel is installed at the bottom of the mobile seat 1, and the mobile seat 1 can be driven to move by the universal wheel. When the scanning platform is used, the cart is pushed to the position of the inspected plant, and the scanning frame is pushed above the plant so that the plant is in the scanning frame.

[0033] In the present utility model, combined with Figure 1 As shown, the top of the mobile seat 1 of this embodiment is also longitudinally and side by side mounted with two telescopic first and second telescopic rods 12 and 14 , a mounting seat 15 is mounted between the top ends of the two first telescopic rods 12 , and the mounting seat 15 is fixedly mounted in the middle of one of the cross bars 17 .

When the height of the scanning frame needs to be adjusted, the limit pin 13 is pressed inward from the outside, and the restriction of the limit pin 13 on the lifting and lowering of the first telescopic rod 12 is released at this time, so that the first telescopic rod 12 can be telescoped and lifted on the second telescopic rod 14. When the first telescopic rod 12 reaches a predetermined height, the limit pin 13 is automatically inserted outward into the limit hole 9 of the corresponding height through the V-shaped spring 18, so as to prevent the first telescopic rod 12 from automatically descending on the second telescopic rod 14.
