[0023] In this embodiment, the user can rotate the bolt member 42 so that one end of the bolt member 42 cancels the abutment with the inner wall of the through groove set on the mounting plate 3, and then the sliding electrical component 44 can be set, so that the electrical component 44 can slide within the stroke range of the through groove set on the mounting plate 3. By rotating the positive and negative threaded rod 6, the two mounting plates 3 can be synchronously driven to align or move outward, and the electrical component 44 installed on the mounting plate 3 can be driven, so that the electrical component 44 can achieve more comprehensive position adjustment to adapt to different installation requirements. Multi-position adjustment makes the position adjustment of the electrical component 44 more convenient and can easily adapt to different generator structures and working environments. At the same time, the device is simple to operate, and the user can easily get started and adjust it. Compared with the existing device, the device solves the problems of limited position adjustment, insufficient flexibility and complicated operation of traditional fixed installation.

[0024] Specifically, refer to Figure 1-2 The center points of the lower end surfaces of the two mounting plates 3 are both equipped with sliders 31 , and the two sliders 31 are respectively embedded and slidable in the slide rails 2 on the same side.

[0025] In this embodiment, the mounting plate 3 is provided with a slider 31 installed at the lower end so that the mounting plate 3 can slide within the travel range of the slide rail 2 .

[0026] Specifically, refer to Figure 4 A bolt member 42 is penetrated through the lower end surface of the U-shaped block 4 and one end of the bolt member 42 is tightly pressed against the inner wall of the through groove of the mounting plate 3 .

[0027] In this embodiment, the bolt member 42 is rotated clockwise so that one end of the bolt member 42 is tightly against the inner wall of the through-slot of the mounting plate 3, thereby completing the positioning of the electrical component 44. Conversely, the bolt member 42 is rotated counterclockwise so that the bolt member 42 is downward and one end of the bolt member 42 is no longer in contact with the inner wall of the through-slot of the mounting plate 3, and then the U-shaped block 4 can be slidably arranged.

Then, the U-shaped block 4 can be slidably arranged to drive the electrical component 44 installed on the upper end of the U-shaped block 4 to slide within the travel range of the through-groove provided on the mounting plate 3 and adjust the position. The reverse threaded rod 6 is limited by the two fixed blocks 5. When the forward and reverse threaded rod 6 rotates, the two fixed blocks 5 engaged with the forward and reverse threads on the outside of the forward and reverse threaded rod 6 are driven and moved, and the slide rails 2 and sliders 31 are cooperated, so that the two mounting plates 3 are centered or moved synchronously outward, thereby driving the electrical components 44 installed on the mounting plates 3 to adjust their positions, and the bolt component 42 is rotated clockwise so that one end of the bolt component 42 is tightly pressed against the inner wall of the through-slot of the mounting plate 3, thereby completing the positioning of the electrical component 44.
