[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A portable nut fastening device includes a mounting frame 1, with four identical connecting posts 2 fixedly connected to the top corners of the mounting frame 1, and an operating box 3 fixedly connected to the top of the four connecting posts 2. It also includes:

[0028] The fixing component, located inside the operating box 3, is used to clamp the outer surface of the nut;

[0029] The clamping assembly, located inside the placement frame 1, is designed to accommodate screws of different sizes. The user inserts the screw through the central area of ​​the placement frame 1 with the head of the screw (the nut portion to be tightened) facing upwards.

[0030] Furthermore, the fixing assembly includes a clamping plate 6, a turntable 11, a fixing cylinder 12, and a first connecting rod 14. The turntable 11 is rotatably connected to the top inner wall of the operating box 3, and the fixing cylinder 12 is fixedly connected to the bottom of the turntable 11. Multiple first connecting rods 14 are rotatably connected to the outer surface of the fixing cylinder 12. The clamping plate 6 is rotatably connected to the outer surface of the multiple first connecting rods 14 in the same vertical direction. Under the action of the first connecting rod 14 and the second connecting rod 16, the multiple clamping plates 6 are driven to clamp the nut.

[0031] Furthermore, the fixing assembly also includes a connecting block 13, a pushing cylinder 15, and a second connecting rod 16. The pushing cylinder 15 is fixedly installed at the bottom of the turntable 11. The pushing cylinder 15 is located inside the fixed cylinder 12. The output end of the pushing cylinder 15 is fixedly connected to the connecting block 13. Multiple annularly distributed second connecting rods 16 are rotatably connected to the outer surface of the connecting block 13. The multiple second connecting rods 16 are rotatably connected to the corresponding clamping plates 6. The output end of the pushing cylinder 15 drives the connecting block 13 to extend and retract. During the extension and retraction process, the connecting block 13 drives the second connecting rods 16 to change angle, further transmitting force to the first connecting rod 14.

[0032] Furthermore, a gear 10 is rotatably connected inside the control box 3, and a drive motor 5 is fixedly installed on the top of the control box 3. The output end of the drive motor 5 is fixedly connected to the gear 10, and the gear 10 is fixedly connected to the turntable 11. The output end of the drive motor 5 drives the gear 10 to rotate. Since the gear 10 is fixedly connected to the turntable 11, the turntable 11 also rotates. The rotation of the turntable 11 can tighten the nut during the rotation process.

[0033] Furthermore, a controller 4 is fixedly installed on the top of the control box 3. The controller 4 is electrically connected to the drive motor 5 and the push cylinder 15. The user starts the push cylinder 15 and the drive motor 5 through the controller 4.

[0034] Furthermore, the clamping assembly includes clamping blocks 7, slots 8, and springs 9. The interior of the placement frame 1 has multiple annular slots 8 distributed at equal intervals. Multiple springs 9 are elastically connected inside the multiple slots 8, and clamping blocks 7 are slidably connected inside the multiple slots 8. The multiple springs 9 are located inside the corresponding clamping blocks 7. The springs 9 and clamping blocks 7 are adjusted within the slots 8, thereby automatically adjusting their positions according to the diameter of the screw, ensuring that the screw is firmly clamped in the placement frame 1 and preventing movement during the tightening process.

[0035] Working principle: When the operator needs to use this portable nut fastening device, when the screw needs to be placed into the device, the user passes the screw through the central area of ​​the placement frame 1, with the head of the screw (the part of the nut to be fastened) facing upwards. The spring 9 and the clamping block 7 are adjusted within the slot 8, thereby automatically adjusting the position according to the diameter of the screw to ensure that the screw is firmly clamped in the placement frame 1 and prevents movement during the fastening process. The user activates the push cylinder 15 through the controller 4. The output end of the push cylinder 15 drives the connecting block 13 to extend and retract. During the extension and retraction of the connecting block 13, the angle of the second connecting rod 16 changes, further transmitting force to the first connecting rod 14. Under the action of the first link 14 and the second link 16, multiple clamping plates 6 are driven to clamp the nut. The user starts the drive motor 5 through the controller 4. The output end of the drive motor 5 drives the gear 10 to rotate. Since the gear 10 is fixedly connected to the turntable 11, the turntable 11 also rotates. During the rotation of the turntable 11, the nut can be tightened. After tightening, the controller 4 controls the push cylinder 15. Through the linkage of the second link 16 and the first link 14, the clamping plate 6 loosens the nut. The user can easily take out the tightened screw and nut assembly. At the same time, the clamping block 7 returns to the initial position under the action of the spring 9, ready to receive the clamping of the next screw.
