[0030] Working principle: When using the device, when the hexagon socket nut needs to be fixed, first, the hexagon socket nut is inserted into the hexagon socket nut sleeve 49. When the hexagon socket nut is inserted into the hexagon socket nut sleeve 49, the inner wall of the hexagon socket nut presses against the right side of multiple limit blocks 413. After the right sides of multiple limit blocks 413 are squeezed by the inner wall of the hexagon socket nut, the multiple limit blocks 413 will rotate. When rotating, the multiple limit blocks 413 will drive the multiple second springs 414 to contract. When the hexagon socket nut is completely inserted into the hexagon socket nut sleeve 49, the multiple limit blocks 413 will press against the left side of the multiple limit blocks 413 due to the elastic force of the multiple second springs 414. On the right side of the hexagon socket nut, the hexagon socket nut is limited, and then the two pull handles 45 are pulled inward, and the two pull handles 45 respectively drive the two pull rods 44 to move inward, and the two pull rods 44 respectively drive the two sliding shaft push-pull blocks 47 to move inward, and the two sliding shaft push-pull blocks 47 respectively drive the sliding shaft 48 to move inward.

[0031] When it is necessary to grind the hexagonal nut, start the motor 17, and the output end of the motor 17 drives the bidirectional screw 18 to rotate. Since the inner wall of the cross bar 24 is threadedly connected to the outer wall side of the bidirectional screw 18, when the bidirectional screw 18 rotates, the cross bar 24 will drive the movable platform 2 to move left and right, thereby adjusting the position of the grinding device 5 and the fixed block 4 for fixing the hexagonal nut, moving to the opposite surface and extending into the inner wall of the grinding tube 32. At this time, the hexagonal nut on the fixed block 4 is also located inside the grinding tube 32. Then, the grinding device 5 is used to start the grinding of the hexagonal nut. The design of the transparent rubber plate 33 makes the grinding process clearly visible, which is convenient for the operator to observe the grinding progress and effect. At the same time, the transparent rubber plate 33 also has a certain protective effect, which can prevent the splashes generated by grinding from causing harm to the operator.

[0032] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
