[0023] Example 2

[0024] like Figure 2-4 As shown, in order to solve the problem that it is inconvenient to control the rotation of the second threaded shaft 5 through the fixed shaft 6, the front end of the fixed shaft 6 is fixedly connected to the limit block 7, and the limit block 7 is slidingly connected to the second threaded shaft 5. The limit block 7 is arranged in a rectangular shape. By arranging a rectangular limit block 7 that slides with the second threaded shaft 5 at the front end of the fixed shaft 6, it is convenient to control the rotation of the second threaded shaft 5 through the fixed shaft 6.

[0025] Example 3

[0026] like Figure 1-3 As shown, in order to solve the problem that it is inconvenient to move the control device mounting plate 9 out of the electrical control cabinet 1, a motor 10 is fixedly connected to the rear side of the top of the electrical control cabinet 1, and a worm 11 is fixedly connected to the end of the main shaft of the motor 10, and the worm 11 is rotatably connected to the electrical control cabinet 1. The spiral direction of one side of the worm 11 is opposite to the spiral direction of the other side of the worm 11, and the worm 11 is symmetrically arranged. A worm wheel 12 is meshed with the outside of the worm 11, and the worm wheel 12 on one side is fixedly connected to the first threaded shaft 2, and the worm wheel 12 on the other side is fixedly connected to the fixed shaft 6. By controlling the motor 10 to drive the worm 11 to mesh with the worm wheel 12, the rotation of the first threaded shaft 2 and the fixed shaft 6 is further controlled, which facilitates the removal of the control device mounting plate 9 from the electrical control cabinet 1.

[0027] Example 4

[0028] like Figure 2-3As shown, in order to solve the problem that it is inconvenient to automatically control the motor 10 to stop after the device mounting plate 9 is moved out and reset, stop switches 13 are fixedly connected to the front and rear ends of the outer side of the slider 3, and the stop switch 13 at the rear end is in contact with the electrical control cabinet 1. After the device mounting plate 9 is moved out and reset, the stop switch 13 on one side is triggered by the slider 3, which facilitates the automatic control of the motor 10 to stop.

[0029] Example 5

[0030] like Figure 2-3 As shown, in order to solve the problem that it is inconvenient to remove the device mounting plate 9 for maintenance, a spring 14 is fixedly connected to the inner side of the device mounting plate 9, and the other end of the spring 14 is fixedly connected to a clamping rod 15, and the clamping rod 15 passes through the device mounting plate 9, and the clamping rod 15 is slidably connected to the device mounting plate 9, and the clamping rod 15 is engaged with the positioning block 8. One end of the outer side of the clamping rod 15 is fixedly connected with a push block 16 that passes through the device mounting plate 9, and the push block 16 is slidably connected to the device mounting plate 9. The push block 16 pushes the clamping rod 15 to compress the spring 14, and at the same time, the clamping rod 15 is disengaged from the positioning block 8, which facilitates the removal of the device mounting plate 9 for maintenance operations.

[0031] Example 6

[0032] like Figure 2-3 As shown, in order to solve the problem of large friction generated when the first threaded shaft 2, the second threaded shaft 5 and the fixed shaft 6 rotate, the outer rear end of the first threaded shaft 2, the outer rear end of the fixed shaft 6 and the outer rear end of the second threaded shaft 5 are fixedly connected with bearings 17, and the bearing 17 at the rear end is fixedly connected to the electrical control cabinet 1, and the bearing 17 at the front end is fixedly connected to the slide rod 4. By connecting the first threaded shaft 2 and the fixed shaft 6 to the electrical controller 1 through the bearings 17, and connecting the second threaded shaft 5 to the slide rod 4 through the bearings 17, the generation of large friction is avoided when controlling the rotation of the first threaded shaft 2, the second threaded shaft 5 and the fixed shaft 6.

[0033] In this embodiment, when the device is maintained, the motor 10 is first started through the controller 18. At this time, the motor 10 will drive the worm 11 to engage the worm wheel 12, and then the worm wheel 12 on one side will control the first threaded shaft 2 to be spirally connected with the slider 3, and the worm wheel 12 on the other side will control the fixed shaft 6 to drive the second threaded shaft 5 to be spirally connected with the positioning block 8 through the rectangular limit block 7. At this time, the first threaded shaft 2 is spirally connected with the slider 3, and the slide rod 4 will continue to slide out of the electrical control cabinet 1, and then be spirally connected with the positioning block 8 at the same time through the second threaded shaft 5. The positioning block 8 will continue to drive the device to be installed through the clamping rod 15. The mounting plate 9 moves to the right side of the slide bar 4. When the slider 3 triggers the stop switch 13 on one side, the motor 10 stops, and the device mounting plate 9 is also moved out of the electrical control cabinet 1 at this time. In this way, when the maintenance personnel subsequently maintain the electrical control cabinet 1, the maintenance personnel's range of movement can be avoided to the greatest extent. In the process of maintaining the device, when it is necessary to remove the device mounting plate 9 for maintenance, the push block 16 pushes the card rod 15 to compress the spring 14, and at the same time, the card rod 15 is disengaged from the positioning block 8, which facilitates the removal of the device mounting plate 9 for maintenance operations, and thus facilitates maintenance operations according to needs.
