[0002] The new energy industry is currently in its development phase, particularly with the widespread use of clean energy sources such as wind, electric, and solar power. The market for instrument transformers has grown significantly. Instrument transformers, which convert high voltage and high current into low voltage and low current, are used for measuring and protecting new energy equipment.

[0003] In the existing technology, operators wrap the enameled wire from the wire package around two pins, solder the two pin conductors of the wire package, and then insert the pins into the pin holes of the transformer housing. Manually pressing the pins into the transformer housing can cause many problems, such as excessive force, the pins being inserted too deep into the pin holes and breaking, or the two pins being at different heights, rendering the product unusable. The manual pressing method is costly and relatively inefficient. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a manual pressure device for fixing the pin of a mutual inductor to solve the above-mentioned problem.

[0006] As a preferred technical solution of the present invention, the other side of the connecting shaft and away from the top end of the rack column is connected to the bracket through a spring.

[0007] As a preferred technical solution of the present invention, the bottom end of the needle pressing rod is connected to a needle pressing block.

[0008] As a preferred technical solution of the present invention, the length, width and height of the fixture are 90-110 mm, 60-80 mm and 10-30 mm respectively.

[0009] As a preferred technical solution of the present invention, the fixture has an axisymmetric structure.

[0010] As an optimal technical solution of the present invention, bolt head limit grooves are respectively opened on both sides of the fixture, a bolt rod limit groove is opened in the middle of the bolt head limit groove, a transformer limit groove is opened in the middle of the fixture, and a pressure pin limit groove is provided on the right side of the transformer limit groove.

[0011] Since the utility model adopts such a structure, the needle pressing tooling has high adjustability and strong replaceability, and the efficiency is greatly improved compared with the manual pressing of pin needles by workers, thereby improving the overall production efficiency and reducing labor costs.
