[0036] The use method and advantages of the utility model: When the power electric transformer is used, the working process is as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, first, the user can pull the transformer fixing steel component 9 out of the bottom end of the transformer fixing base 6, so that the rotating connecting rod 11 is stretched, and rotate the transformer fixing steel component 9 so that the two ends of the transformer fixing steel component 9 face the front and rear sides, and then the side fixing steel components 10 at the front and rear ends of the transformer fixing steel component 9 can be pulled out of the inside of the transformer fixing steel component 9, and at the same time, the fixing steel component limit plate 14 can be rotated out of the rectangular groove of the side fixing steel component 10, and then the limit plate fixing component 15 can be rotated around the rotating shaft to make it fit the front and rear surfaces of the transformer fixing base 6 and fix the limit plate fixing component 15 to the front and rear surfaces of the transformer fixing base 6 by fixing screws 16, so that the side fixing steel component 10 can be limited to the front and rear sides of the transformer fixing steel component 9, and then the transformer fixing bolt 13 can be rotated into the threaded groove of the fixed connecting plate 12, so that the transformer fixing bolt 13 can fix the side fixing steel component 10 and the fixed connecting plate 12 at the installation position, and connect components such as wires through the electrical connector 2;
