[0037] In this embodiment, in order to achieve the effect that the voltage transformer can rotate horizontally after being fixed, a rotating connection assembly 5 is designed. An annular chute 5-1 is provided on the surface of the stable base plate 1, and a rotating ring 5-2 is slidably connected inside. The annular chute 5-1 and the rotating ring 5-2 are circular.

[0043] In this embodiment, the inner threaded pipe 4-6 is located inside the long hole 4-2, which will not block the voltage transformer and is convenient for pushing and moving the position on the surface of the mounting frame 2.

[0044] Further, the transverse screw 6-1 has a double-thread structure, and the thread directions of the threads at both ends of the transverse screw 6-1 are positive helix and reverse helix respectively.

[0045] In this embodiment, due to the two different thread directions, when the transverse screw 6-1 rotates, it can drive the two cross bars 6-3 to move towards the center or both sides simultaneously.

[0046] Further, the stabilizing base plate 1 is integrally circular in structure.

[0047] In this embodiment, due to the circular structure, the mounting frame 2 can rotate around the stabilizing base plate 1, can stably support the voltage transformer, and can reduce the contact area between the bottom and the tabletop or the ground, and can be installed on various tabletops.

[0048] When in use, fix the position of the stabilizing base plate 1, place the voltage transformer on the mounting frame 2 and adjust its position, align the bottom mounting holes of the voltage transformer with the long holes 4-2, then according to the positions of the mounting holes, turn the adjusting screw 4-3 to drive the moving block 4-5 to adjust the position of the internally threaded tube 4-6, align the internally threaded tube 4-6 with the mounting holes, then pass the fixing bolt 4-7 through the mounting holes and screw it into the internally threaded tube 4-6 for fixation. Subsequently, perform the assembly operation. When rotation is required, turn the screwing block 7 to make the support seat 5-7 leave the surface of the stabilizing base plate 1, and then the mounting frame 2 can be pushed and rotated arbitrarily. After the assembly is completed, the mounting frame 2 is kept in a fixed and non-rotatable state. Turn the transverse screw 6-1 to make the lifting seat 6-5 lift the voltage transformer upwards to separate it from the surface of the mounting frame 2, and then the voltage transformer can be taken away.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
