[0028] ​A second spring 12 is connected between each of the four telescopic clamping rods 11 and the rotating block 10. Through the arrangement of the telescopic clamping rods 11, when the telescopic clamping rods 11 are pulled and compressed, the rotating block 10 can drive the telescopic clamping rods 11 to release the fixation of the embedding seat 2. On the upper side of the pole-mounted complete transformer body 1, two symmetrically arranged U-shaped bottom plates 4 are installed. Connecting rods 5 are connected to the inner sides of the two U-shaped bottom plates 4. The outer surfaces of the two connecting rods 5 are respectively slidably connected with a first cross plate 6 and a second cross plate 7. Plug-in blocks 9 are arranged in an array on the inner sides of the first cross plate 6 and the second cross plate 7.

[0029] Two first springs 8 are fixedly connected between the first cross plate 6 and the second cross plate 7. Through the installation and use of the first cross plate 6 and the second cross plate 7, the two cross plates can clamp the front and rear sides of the embedding seat 2 to fix the wiring terminal 3. Two first bolts 13 are threadedly connected to the upper sides of the first cross plate 6 and the second cross plate 7. Through the arrangement of the first bolts 13, the two cross plates can be squeezed and fixed by using the first bolts 13, so that the two cross plates can be fixed on the two connecting rods 5, ensuring that the plug-in blocks 9 at the cross plates can stably fix the wiring terminal 3. The plug-in blocks 9 and the telescopic clamping rods 11 are used to fix the embedding seat 2.

[0030] A vertical rod 14 is installed on the upper side of the pole-mounted complete transformer body 1. A sliding block 15 is slidably clamped on the outer surface of the vertical rod 14. U-shaped blocks 17 arranged in an array are installed on the rear side of the sliding block 15. The U-shaped blocks 17 are used to fix the wiring head 111.

[0031] A positioning plate 19 is slidably clamped inside the wiring terminal 3. The positioning plate 19 is used for the wiring head 111. A fixing block 20 is fixedly installed on the rear side of the wiring terminal 3. A movable rod 21 is slidably connected inside the wiring terminal 3. The rear side of the movable rod 21 penetrates through the fixing block 20 and extends to the rear side of the fixing block 20. A third spring 22 is fixedly connected between the movable rod 21 and the wiring terminal 3. A circular plate 23 is connected to the rear side of the movable rod 21.

[0032] A positioning groove 222 is formed on one side of the embedding seat 2. The positioning groove 222 is adapted to the telescopic clamping rod 11. One side of the telescopic clamping rod 11 is slidably clamped with one side of the embedding seat 2 through the positioning groove 222.

[0033] Installation clamping grooves 333 are formed at both ends of the embedding seat 2. The installation clamping grooves 333 are adapted to the plug-in blocks 9. The inner sides of the plug-in blocks 9 are clamped with both ends of the embedding seat 2 through the installation clamping grooves 333.

[0034] The working principle of a wiring structure of a pole-mounted complete transformer provided by the present utility model is as follows:

[0035] By clamping a plurality of embedding seats 2 above the pole-mounted complete transformer body 1, the embedding seats 2 will initially fix the wiring terminals 3. Subsequently, rotate the two rotating blocks 10 so that the two rotating blocks 10 can drive the telescopic clamping rods 11 installed with the second springs 12 to move to the embedding seats 2. Then, squeeze the elastic telescopic clamping rods 11 so that the telescopic clamping rods 11 can be telescopically adjusted and inserted into the positioning grooves 222 of the embedding seats 2. Then, rotate the first bolts 13 respectively to release the first cross plate 6 and the second cross plate 7 installed with the first springs 8, so that the plug-in blocks 9 at the two cross plates can be clamped into the installation slots 333 of the embedding seats 2 for further fixing and positioning the installation of the wiring terminals 3, improving the stability of the wiring terminals 3. In this way, the wiring terminals 3 can be conveniently replaced by the clamping method, saving the replacement time and improving the replacement efficiency of the wiring structure;

[0036] By pulling the circular plate 23, the circular plate 23 can drive the movable rod 21 installed with the third spring 22 to move and be stored. Then, let the wiring head 111 be clamped above the wiring terminal 3. Subsequently, insert the positioning plate 19 into the wiring terminal 3 and the wiring head 111 for fixing the wiring head 111. Then, release the circular plate 23, so that the elastic movable rod 21 can automatically extend and be positioned inside the positioning plate 19 to limit and fix the entire wiring head 111. Then, move the sliding plate 15 on the vertical rod 14 so that the U-shaped stopper 17 at the sliding plate 15 can be limited and fixed above the wiring head 111. Then, rotate the second bolts 16 respectively so that the second bolts 16 can squeeze and fix the sliding plate 15, so as to make the wiring structure of the pole-mounted complete transformer more stable and reliable.
