A positioning screw 16 is threadedly connected to the inner wall of the top middle of the inverted U-shaped connecting rod 15. The bottom of the outer wall of the positioning screw 16 is movably connected to the inner wall of one of the positioning grooves 12.

[0024] In order to accommodate cables or walls of different lengths during use, the extension frame 14 can slide along the inner wall of the cable tray body 11. By moving the inverted U-shaped connecting rod 15 in the side groove 13, the length of the extension frame 14 extending out of the cable tray body 11 can be adjusted. After the extension frame 14 is adjusted to the appropriate position, the positioning screw 16 is rotated so that the bottom of the positioning screw 16 is engaged in the corresponding positioning groove 12 to fix the extension frame 14. Thus, the length of the cable tray can be adjusted according to actual usage needs, improving the practicality of the cable tray.

[0025] Please see Figure 3-4 The angle adjustment assembly 2 includes a connecting plate 21. The top of the connecting plate 21 is fixedly connected to the left side of the bottom of the cable tray body 11. A hinge block 25 is fixedly connected to the right side of the bottom of the connecting plate 21. An inverted U-shaped control frame 23 is fixedly connected to the bottom of the connecting plate 21 near the hinge block 25. A guide rail plate 22 is fixedly connected to the left side of the bottom of the connecting plate 21. A lead screw 24 is threadedly connected to the inner wall of the bottom of the inverted U-shaped control frame 23. The top end of the lead screw 24 extends to the inner side of the inverted U-shaped control frame 23 and is movably connected to a sliding frame 26. Slider blocks 27 are fixedly connected to the front and rear sides of the sliding frame 26, respectively. The outer walls of the two sliders 27 are slidably connected to the inner walls of the front and rear sides of the inverted U-shaped control frame 23, respectively. A rotating rod 28 and a second rotating rod 29 are rotatably connected to the inner wall of the sliding frame 26, respectively. The side of the rotating rod 28 that is close to the second rotating rod 29 is rotatably connected to the inner wall of the hinge block 25.

The inner sides of the two angle adjustment rods 214 that are away from the push-pull crossbar 213 are rotatably connected to the front and rear sides of the second bridge frame 17 respectively.

[0026] When the angle of the cable tray needs to be adjusted according to the angle of the corner, the lead screw 24 can be rotated. When the lead screw 24 rotates within the inverted U-shaped control frame 23, it can drive the sliding frame 26 to move up and down along the inner wall of the inverted U-shaped control frame 23. While the sliding frame 26 moves, it can drive the rotating rod 28 and the second rotating rod 29 to rotate. While the rotating rod 28 and the second rotating rod 29 rotate, they can drive the U-shaped connecting rod 210 to move. While the U-shaped connecting rod 210 moves, it can drive the push-pull block 211 to slide at the bottom of the guide rail plate 22. While the push-pull block 211 slides, it can drive the connecting block 212 and the push-pull crossbar 213 to move. While the push-pull crossbar 213 moves, the second cable tray 17 can be rotated through the angle adjustment rod 214, thereby adjusting the angle between the second cable tray 17 and the cable tray body 11. This allows the cable tray to be adaptively adjusted according to the angle of the corner, further improving the practicality of the cable tray.

[0027] Working principle: When using this device, in order to adapt to cables or walls of different lengths during use, the extension frame 14 can slide along the inner wall of the cable tray body 11, and adjust the length of the extension frame 14 extending out of the cable tray body 11 by moving the inverted U-shaped connecting rod 15 in the side groove 13. After the extension frame 14 is adjusted to the appropriate position, the positioning screw 16 is rotated so that the bottom of the positioning screw 16 is engaged in the corresponding positioning groove 12 to fix the extension frame 14, thereby adjusting the length of the cable tray according to actual usage requirements.

[0028] When the angle of the cable tray needs to be adjusted according to the angle of the corner, the lead screw 24 can be rotated. When the lead screw 24 rotates within the inverted U-shaped control frame 23, it can drive the sliding frame 26 to move up and down along the inner wall of the inverted U-shaped control frame 23. While the sliding frame 26 moves, it can drive the rotating rod 28 and the second rotating rod 29 to rotate. While the rotating rod 28 and the second rotating rod 29 rotate, they can drive the U-shaped connecting rod 210 to move. While the U-shaped connecting rod 210 moves, it can drive the push-pull block 211 to slide at the bottom of the guide rail plate 22. While the push-pull block 211 slides, it can drive the connecting block 212 and the push-pull crossbar 213 to move. While the push-pull crossbar 213 moves, the second cable tray 17 can be rotated through the angle adjustment rod 214, thereby adjusting the angle between the second cable tray 17 and the cable tray body 11, so that the cable tray can be adaptively adjusted according to the angle of the corner.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
