A vertical groove 21 is opened on the side of the vertical plate 2, a center groove 5 is opened in the middle position of the side of the vertical plate 2, and the lower clamping plate 3 is fixedly set at the bottom of the front side of the vertical plate 2. The upper clamping plate 8 includes a vertical section and a horizontal section. The horizontal section of the upper clamping plate 8 and the lower clamping plate 3 are equidistantly provided with wire holes 31 in the horizontal direction to assist the wiring work of the programmable controller.

[0021] A center plate 1 is fixedly provided in the middle position at the bottom of the upper folding plate 8, and an adjustment limit assembly for adjusting the distance between the upper folding plate 8 and the lower clamping plate 3 is provided on the center plate 1. The adjustment limit assembly includes a locking bolt 10, an anti-slip ring 9, and a guide column 11. The top of the center plate 1 is fixedly provided at the bottom of the upper folding plate 8, and an installation groove 4 is opened at the center position of the front side of the center plate 1. Locking bolts 10 are screwed into threads on both sides of the installation groove 4. An anti-slip ring 9 is fixedly provided on one end of the locking bolt 10 extending into the installation groove 4. The anti-slip ring 9 prevents the locking bolt 10 from being excessively screwed out and causing the locking bolt 10 to be lost.

[0022] The locking bolt 10 passes through the vertical groove 21, and the width of the head of the locking bolt 10 is greater than the width of the vertical groove 21. Threaded holes 13 are provided at the bottom of the two side surfaces of the center plate 1, and a guide column 11 is screwed into the threaded hole 13. A hexagonal groove 12 is provided at the head of the guide column 11. The guide column 11 extends into the vertical groove 21 and is the same width as the vertical groove 21. The setting of the guide column 11 assists the center plate 1 to move in the vertical direction of the center groove 5.

[0023] An extension plate 6 is fixedly provided at the bottom of the lower clamping plate 3 on the vertical plate 2, and a U-shaped groove 61 is symmetrically provided on the front side of the extension plate 6. When a bolt is screwed into the U-shaped groove 61, the position of the entire fixed structure in the horizontal direction can be fine-tuned. Edge rings 7 are symmetrically fixedly provided at the bottom of both side surfaces of the vertical plate 2, and holes are provided on the side surfaces of the edge rings 7. The U-shaped groove 61 and the edge ring 7 make it convenient for workers to fix the entire fixed structure to the frame using screws.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] Insert the center plate 1 into the center groove 5, and use a wrench to sequentially pass the locking bolt 10 through the vertical groove 21 and screw it into the installation groove 4. Then use a bolt to fix the anti-slip ring 9 at the end of the locking bolt 10, pass the guide column 11 through the vertical groove 21, and use an Allen wrench to screw the guide column 11 into the threaded hole 13, insert the screw into the U-shaped groove 61 and the edge ring 7, and screw the screw into the machine base. According to the actual height of the programmable controller, fix the upper clamping plate 8 at an appropriate distance close to the lower clamping plate 3, and finally tighten the locking bolt 10.

[0026] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
