An angle-shifting bracket 13 is fixedly installed on the end face by a threaded set screw 12. A universal ball 14 is provided at the inner end of the angle-shifting bracket 13. A support shaft 100 is fixed on the surface of the base 1. A copper wire drum 101 is sleeved on the outer surface of the support shaft 100. By using a support shaft to sleeve the copper wire drum, it can be shifted outside the copper wire drum by the angle-shifting bracket. The copper wire drum can be positioned and shifted. It is convenient to install, disassemble and replace. When winding, it is convenient to shift the position and wind. When positioning the transformer winding, it is compressed and squeezed by the left and right extrusion plates, and the clamping and fixing are flexible. The angle-shifting bracket 13 is supported at the outer end of the copper wire drum 101, and the universal ball 14 of the angle-shifting bracket 13 is attached to and supported on the upper and lower end surfaces of the copper wire drum 101. The angle-shifting bracket 13 can be supported on the outside of the copper wire drum 101, and can position the copper wire drum 101. When the electric lifting cylinder 10 drives the push rod 11 to move up and down, it can drive the angle-shifting bracket 13 to move up and down, and can move the copper wire drum 101 up and down. The universal ball 14 squeezes the copper wire drum 101 to move it. When the universal ball 14 supports the copper wire drum 101, the copper wire drum 101 rotates when winding. When rotating, it rotates at the support shaft 100 and is attached to the universal ball 14 to reduce friction and make it easy to rotate when moving. The threaded set screw 12 is fixedly locked to the inner end surface of the angle-shifting bracket 13. A torque handle 120 is fixedly connected to one outer surface of the threaded set screw 12. The threaded set screw 12 can be tightened to fix the angle-shifting bracket 13, which is convenient for fixing the angle-shifting bracket 13 and the push rod 11. It is easy to install. The torque handle 120 is provided on the outside of the threaded set screw 12. The torque handle 120 is convenient for turning the threaded set screw 12 to lock and loosen. It is easy to operate. One end face of the bolt rod 4 is provided with a hexagonal boss 9; during operation, it is convenient to use a wrench to be engaged and rotated on the outside of the hexagonal boss 9, making it easy to twist and operate. The outer surfaces of the first extrusion plate 6 and the second extrusion plate 8 are covered with a rubber layer; when the transformer winding is extruded by the first extrusion plate 6 and the second extrusion plate 8, it is firmly fixed and the friction is increased; the inner end of the copper wire drum 101 is tightly sleeved on the outer surface of the support shaft 100, and the surface of the copper wire drum 101 is wound with copper wire; the sleeve is stable, and when winding, pulling the copper wire to rotate can drive the copper wire drum 101 to rotate stably outside the support shaft 100. The lower surface of the base 1 is provided with support legs, and four sets of support legs are distributed and fixed on the lower surface of the base 1; the support is stable. In use, a support plate 3 is fixedly connected to the end face of the drive shaft of the motor 2. The surface of the support plate 3 is provided with a groove 30. The inner surface of the groove of the support plate 3 is connected to a bolt rod 4 through a bearing.

When the bolt rod 4 is twisted, the forward thread 5 of the bolt rod 4 can be driven to rotate inside the first extrusion plate 6, and the reverse thread 7 can be driven to rotate at the second extrusion plate 8. This can drive the first extrusion plate 6 and the second extrusion plate 7 to contract and slide synchronously. When twisted in the reverse direction, they expand synchronously, which can facilitate clamping the transformer winding. Furthermore, a support shaft 100 is fixed to the surface of the base 1, and a copper wire drum 101 is sleeved on the outer surface of the support shaft 100. In use, the copper wire is pulled and fixed outside the transformer winding. The rotation of the motor 2 and the support disc 3 drives the transformer winding to rotate, thus winding the copper wire. The angle-shifting bracket 13 supports the outer end of the copper wire drum 101, and the universal ball 14 of the angle-shifting bracket 13 is fitted and supported against the upper and lower surfaces of the copper wire drum 101. The angle-shifting bracket 13 can support the copper wire drum 101 externally, allowing for the adjustment of the copper wire drum 101. When the electric lifting cylinder 10 drives the push rod 11 to move up and down, it can drive the angle-shifting frame 13 to move up and down, which can move the copper wire drum 101 up and down. It can move the copper wire drum 101 up and down and wind the wire. It is easy to use. The copper wire drum 101 is pushed by the universal ball 14. When the universal ball 14 supports the copper wire drum 101, the copper wire drum 101 rotates when winding. When rotating, it is supported at the support shaft 100 and rotates in contact with the universal ball 14, which reduces friction and makes it easy to rotate when shifting.
