The front parts of the switch knob 9 and the two adjustment knobs 10 are each provided with a rotary seat 11, and multiple rotary seats 11 are each provided with a mounting groove 16, and multiple mounting grooves 16 are each slidably connected with a slide plate 12, and the rear ends of the multiple slide plates 12 are each fixedly installed with a connecting rod 13, and the rear ends of the multiple connecting rods 13 are respectively fixedly installed on the corresponding switch knob 9 and the adjustment knob 10, and the outer sides of the multiple connecting rods 13 are each sleeved with a spring 15, and the outer sides of the switch knob 9 and the two adjustment knobs 10 in the groove 3 are fixedly sleeved with an inner gear ring 17, and the outer sides of the multiple rotary seats 11 are fixedly sleeved with an outer gear ring 18, which is meshed and connected in the inner gear ring 17.

[0022] The right side of the power calibration device body 1 is connected to a protective cover 4 by a hinge, and a buckle 5 is fixedly installed on the right side of the protective cover 4. A card seat 6 is fixedly installed on the left side of the power calibration device body 1. The protective cover 4 can form a shielding protection for the display screen 2. One side of multiple springs 15 is fixedly installed on the slide 12, and the side of multiple springs 15 away from the slide 12 is fixedly installed in the rear end of the mounting groove 16. This design is conducive to the use of this device. The mounting groove 16 is set to a hexagonal shape, and the slide 12 is set corresponding to the mounting groove 16. Through this design, when the rotary seat 11 rotates, the slide 12 can be driven to rotate synchronously. The front ends of multiple rotary seats 11 are fixedly installed with a screw ring 14, which is convenient for pulling the rotary seat 11 through the screw ring 14, which is convenient for using the rotary seat 11.
