By setting the first auxiliary rotating ring 3, specifically, when the first internal gear 4 is rotated clockwise, the six gears 331 are driven to rotate, and at the same time, the gears 331 drive the adjustment plate 36 to slide inside the adaptation slot 32 towards the inside of the wrench body 1, thereby achieving adaptation to a smaller nut size. When it is a larger-sized nut, the first internal gear 4 is rotated counterclockwise, so that the gears 331 rotate counterclockwise. At the same time, the gears 331 drive the adjustment plate 36 to move away from the center of the first auxiliary rotating ring 3, so as to be able to adapt to nuts with larger sizes, improving the applicable range of the device.

[0030] A second auxiliary rotating ring 31 is fixedly connected to the bottom of the six connecting rods 33. The top of the second auxiliary rotating ring 31 is rotatably connected to the bottom of the wrench body 1.

[0031] Gears 331 are rotatably connected to the outer surfaces of the six connecting rods 33. The parts connected by the six gears 331 are the same. The tops of the six gears 331 are in contact with the bottom of the first auxiliary rotating ring 3.
