[0002] The transformer is mainly used to change the AC voltage, and there is an iron core in its components, and the iron core is mainly used to wind copper wire. After winding, the iron core can achieve the effect of electromagnetic induction. The announcement number is CN208722735U, which discloses an iron core fixing device for winding a transformer coil with an iron core fixing component, which relates to the technical field of transformer manufacturing, and is used to fix the iron core on a workbench, so that workers do not have to hold the iron core and wind the coil on the iron core, solving the problem that workers hold the iron core but are inconvenient to wind the coil on the iron core; comprising: a base; a bottom plate arranged on the base; a fixing member arranged on the base for fixing the base to the workbench; a fixing block arranged on the bottom plate; a fixing plate arranged on the fixing block; and a clamping component slidably assembled on the fixing plate for cooperating with the fixing plate to clamp or unclamp the iron core; the above patent still has the defect that the iron core cannot be rotated after being fixed to realize direct rotation and winding, which not only affects the overall work efficiency, but also cannot reduce labor, resulting in a large waste of human resources.

[0003] The disclosure (announcement) number is CN218849228U, which discloses an iron core fixing component for transformer coil winding, including a table; the utility model can have the advantage of being able to directly rotate and wind after the iron core is fixed by setting a fixed rotating mechanism, which not only improves the overall work efficiency, but also reduces labor and avoids waste of human resources. The cooperation between the motor, the connecting rod, the turntable and the main gear is used to play a driving role, and the cooperation between the electric push rod and the fixed plate is used to play a role of tightening and fixing, so that it can be directly rotated and wound after the fixation is completed to achieve the desired effect.
