[0035] Reference Figure 1 、 Figure 2 、 Figure 4 The adjustment component also includes a turntable 42, which is located in a front position above the support plate 2, but the front end of the turntable 42 is still a certain distance away from the front end of the support plate 2. The turntable 42 can rotate flexibly, and the rear surface of the turntable 42 is fixedly connected to a threaded rod 43. Rotating the turntable 42 can drive the threaded rod 43 to rotate synchronously. The threaded rod 43 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The upper surface of the support plate 2 is slidably connected to a positioning block 44, which slides in the front and rear directions along the upper surface of the support plate 2, and the left surface of the positioning block 44 is hinged with a connecting rod 45.

[0036] Reference Figure 1 - Figure 3 The quick-release assembly includes a lever 53, the front end of which protrudes from the front surface of the mounting plate 47 for easy movement. The inner wall of the mounting plate 47 is elastically connected to a block 52 through a compression spring 51, and a slot 501 is provided on the left surface of the mounting foot 3, and the block 52 fits in the slot 501.

[0037] Reference Figure 1 、 Figure 2 、 Figure 4 The fixing block 41 is fixedly connected to the front end of the upper surface of the support plate 2, the support plate 2 provides support for the fixing block 41, the lower surface of the mounting plate 47 is in contact with the upper surface of the support plate 2, the support plate 2 provides support for the mounting plate 47, and the outer wall of the mounting plate 47 is in contact with the inner wall of the mounting foot 3, which can prevent the transformer body 1 from shaking when the installation is completed.

[0038] Reference Figure 1 、 Figure 2 、 Figure 4 A handle is fixedly connected to the front surface of the turntable 42 away from the center of the circle, and the handle is convenient for grasping. The threaded rod 43 passes through and is rotatably connected to the front surface of the fixed block 41. The threaded rod 43 passes through and is threadedly connected to the front surface of the positioning block 44. When the threaded rod 43 rotates, it will drive the positioning block 44 to move in the front and back directions.

[0039] Reference Figure 1 、 Figure 2 、 Figure 4 The left end of the connecting rod 45 is hinged to the right surface of the slider 46. When the positioning block 44 moves, it will squeeze the connecting rod 45, and the connecting rod 45 will swing under the squeeze. When the connecting rod 45 swings, it will drive the slider 46 to move horizontally. There are two groups of connecting rods 45, sliders 46, mounting plates 47, and mounting feet 3. The two groups of connecting rods 45, sliders 46, mounting plates 47, and mounting feet 3 are symmetrically distributed on the left and right sides with respect to the center line of the support plate 2. Under the connection of the connecting rod 45, when the positioning block 44 moves, it will drive the sliders 46 on both sides to shrink or open synchronously.

[0040] Reference Figure 1 - Figure 3 The lever 53 passes through and is slidably connected to the front surface of the mounting plate 47, sliding horizontally. The block 52 is inserted into the inner wall of the slot 501 to limit the mounting foot 3. The upper surface of the block 52 is set to an arc surface. When the arc surface of the block 52 is squeezed, the block 52 will retract into the mounting plate 47 to release the obstruction to the mounting foot 3. The rear surface of the lever 53 is fixedly connected to the front surface of the block 52. When the lever 53 moves, it will drive the block 52 to move synchronously.

[0041] Reference Figure 1 - Figure 3 The block 52 passes through and is slidably connected to the left surface of the mounting plate 47, sliding horizontally. One end of the compression spring 51 is fixedly connected to the right surface of the block 52, and the other end of the compression spring 51 is fixedly connected to the inner wall on the right side of the mounting plate 47. When the block 52 is retracted into the mounting plate 47, it will squeeze the compression spring 51 to generate a reaction force.

[0042] Working Principle: To adjust the spacing of mounting plates 47 to accommodate different transformer body models 1, the handle on the front surface of the turntable 42 is gripped and rotated, causing the threaded rod 43 fixed to its rear surface to rotate. Because the threaded rod 43 extends through and is threadedly connected to the front surface of the positioning block 44, and the positioning block 44 slides along the upper surface of the support plate 2, the rotation of the threaded rod 43 causes the positioning block 44 to move forward and backward along the upper surface of the support plate 2. As the positioning block 44 moves, it compresses the connecting rod 45 to which it is hinged, causing the connecting rod 45 to swing. This movement of the connecting rod 45 drives the slider 46 and mounting plate 47 to move laterally. Because the connecting rod 45, slider 46, mounting plate 47, and mounting foot 3 are arranged in two sets, symmetrically about the centerline of the support plate 2, the movement of the positioning block 44, driven by the connection of the connecting rod 45, causes the sliders 46 and mounting plates 47 on both sides to retract or expand synchronously, thereby changing the spacing between the mounting plates 47 to adjust the position of the mounting foot 3.

[0043] After adjusting the position of the mounting plate 47, install the transformer body 1. During installation, the mounting foot 3 is placed on the outer wall of the mounting plate 47. The lower surface of the mounting foot 3 will press the curved surface of the block 52, causing the block 52 to retract into the mounting plate 47 and compress the compression spring 51. When the mounting foot 3 is completely placed on the outer wall of the mounting plate 47, the slot 501 will align with the block 52. The reaction force of the compression spring 51 will push the block 52 into the slot 501, thereby limiting and fixing the mounting foot 3. When it is necessary to remove the mounting foot 3, the levers 53 on both sides are simultaneously moved. The levers 53 drive the block 52 to move horizontally and disengage from the slot 501, releasing the obstruction on the mounting foot 3, and the mounting foot 3 can be removed from the mounting plate 47.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
