A cavity is provided inside the fixed block 8, and an adjusting mechanism 9 is provided inside the cavity. A gear disk 10 is fixedly sleeved above the surface of the adjusting mechanism 9. A screw rod 11 is fixedly connected to the surface of the fixed block 8, and the screw rod 11 slides through the support frame 3 on the other side. A threaded sleeve is provided on the surface of the screw rod 11, and the surface of the threaded ring 12 contacts the inner wall of the support frame 3 on the other side. A top plate 15 is fixedly connected to the top of the adjusting mechanism 9, and a rack plate 13 is slidably connected to the bottom of the top plate 15. There are two rack plates 13, and the rack plates 13 are meshed with the gear disk 10. A guide rod 14 is fixedly connected to the top of the rack plate 13, and guide grooves 16 are provided on both sides of the top of the top plate 15. The surface of the guide rod 14 contacts the inner wall of the guide groove 16. A clamping mechanism 17 is provided at one end of the rack plate 13, and the number of the clamping mechanisms 17 is two groups.

[0025] The adjusting mechanism 9 includes a rotating shaft 91, a worm gear 92 and a worm 93. The bottom of the rotating shaft 91 is rotatably connected to the bottom of the inner wall of the cavity, the top of the rotating shaft 91 rotates and passes through the top of the fixed block 8, and the top plate 15 is fixedly connected to the top of the rotating shaft 91. The worm gear 92 is fixedly sleeved on the surface of the rotating shaft 91, and one end of the worm gear 93 is rotatably connected to the inner wall of the cavity.

When the staff turns the handle, the worm gear 93 rotates accordingly to drive the worm gear 92 to rotate. Accordingly, the gear plate 10 can be driven to rotate by the cooperation of the worm gear 92 and the worm gear 93. Accordingly, the state of the clamping mechanism 17 can be adjusted by the cooperation of the gear plate 10 and the rack plate 13.

[0026] The clamping mechanism 17 includes a vertical plate 171, a clamping plate 172 and a limit plate 173. The vertical plate 171 is fixedly connected to one end of the rack plate 13. The clamping plate 172 is fixedly connected to the surface of one side of the vertical plate 171. The surface of the clamping plate 172 contacts the inner wall of the channel steel 6. The size of the longitudinal section of the clamping plate 172 is the same as the size of the longitudinal section of the inner wall of the channel steel 6. The length of the clamping plate 172 is equal to the length of the vertical plate 171 and is equal to the length of the horizontal plate 7. When the staff adjusts the state of the rack plate 13 through the gear plate 10, The two vertical plates 171 respectively drive the two clamping plates 172 to move toward opposite sides, so that the position of the channel steel 6 can be limited by the clamping plates 172 in cooperation with the inner wall of the channel steel 6 to ensure the accuracy of the installation position of the transformer body 5. The limiting plate 173 is fixedly connected to the surface of the other side of the vertical plate 171, and the surface of the limiting plate 173 is slidably connected to the inner wall of the limiting groove 18.

[0027] The diameter of the guide rod 14 is equal to the width of the inner wall of the guide groove 16 , and the height of the top of the top plate 15 is lower than the height of the top of the support frame 3 , thereby increasing the practicality of the guide rod 14 and the top plate 15 .

[0028] Working principle: The staff first fixes the fixing ring 1 on the surface of the pole by using the positioning bolt 2 in conjunction with the fixing ring 1, and then the staff can place the support frames 3 on both sides respectively on both sides of the top of the fixing ring 1. During this process, the staff can fix the state between the two support frames 3 by using the screw rod 11 in conjunction with the threaded collar 12 and the setting of the connecting rod 4. After that, the staff can place the transformer body 5 on the top of the support frame 3 and then turn the handle. The adjustment mechanism 9 and the gear plate 10 can be used in conjunction to drive the two rack plates 13 to move. At this time, the two sets of clamping mechanisms 17 are used in conjunction, and moving toward opposite sides can limit the position of the channel steel 6. The channel steel 6 is placed in the middle position of the top of the support frame 3. At this time, the staff can use the locking bolt to fix the position of the channel steel 6. Based on this, the mounting frame can stably support and fix the position of the power transformer.
