[0025] One end of the double threaded rod (8) is rotatably mounted on one of the fixed plates (3), and the other end passes through another fixed plate (3), with a throttle (4) fixedly provided on the end.

[0026] In this embodiment, during use, the cable passes through the cable tray (2) and the device is fixed. When the height of the device needs to be adjusted, the throttle (4) is turned. The throttle (4) drives the double threaded rod (8) to rotate. When the double threaded rod (8) rotates clockwise, the two ends of the lifting mechanism (5) move on the double threaded rod (8) and approach each other. At this time, the active state tends to be vertical, and the height of the entire device is stretched. Since the top of the device is fixed, the support frame (1) drives the cable tray (2) to move down. When the double threaded rod (8) rotates counterclockwise, the two ends of the lifting mechanism (5) move on the double threaded rod (8) and move away from each other. At this time, the active state tends to be horizontal, and the height of the entire device is compressed. The support frame (1) drives the cable tray (2) to move up.

[0027] This embodiment can adjust the height of the cable tray (2). Through the double threaded rod (8) and the lifting mechanism (5), the rotation of the double threaded rod (8) drives the operation of the lifting mechanism (5). When the double threaded rod (8) rotates clockwise, the two ends of the lifting mechanism (5) move on the double threaded rod (8) and move closer to each other. At this time, the active state tends to be vertical, and the height of the entire device is stretched. When the double threaded rod (8) rotates counterclockwise, the two ends of the lifting mechanism (5) move on the double threaded rod (8) and move away from each other. At this time, the active state tends to be horizontal, and the height of the entire device is compressed. The height of the cable tray (2) can be adjusted according to actual needs, which is convenient and practical.

The second mounting base (505) is fixedly mounted on the support frame (1).

[0030] In the embodiment, during use, the cable passes through the bridge (2), and the device is fixed. When it is necessary to adjust the height of the device, the knob (4) is rotated, the knob (4) drives the double-threaded rod (8) to rotate, when the double-threaded rod (8) rotates clockwise, the two ball nuts (501) move on the double-threaded rod (8) and approach each other, the ball nut (501) drives the first lifting rod (502) and the second lifting rod (504) to rotate, the first lifting rod (502) and the second lifting rod (504) gradually tend to be vertical, at this time, the height of the entire device is lengthened; when the double-threaded rod (8) rotates counterclockwise, the two ball nuts (501) move on the double-threaded rod (8) and move away from each other, the ball nut (501) drives the first lifting rod (502) and the second lifting rod (504) to rotate, the first lifting rod (502) and the second lifting rod (504) gradually tend to be horizontal, at this time, the height of the entire device is compressed.
