[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1 , Figure 2 and Figure 3As shown, this utility model embodiment provides a novel screw fastening device, specifically including a housing 1. A hydraulic cylinder 4 is rotatably connected inside the housing 1. A support shell 5 is fixedly connected to the output end of the hydraulic cylinder 4. The outer wall of the support shell 5 is slidably connected to the inside of the housing 1. A cylinder 6 is fixedly connected inside the support shell 5. A connecting block 7 is fixedly connected to the output end of the cylinder 6. The outer wall of the connecting block 7 is slidably connected to the inner wall of the support shell 5. A support block 8 is also connected to the inner wall of the connecting block 7. A clamping block 9 is rotatably connected to the outer wall of the support block 8. A spring 10 is fixedly connected inside the clamping block 9. The outer wall of the spring 10 is fixedly connected to the inside of the support block 8. A spring 2 12 is fixedly connected to the upper surface of the support block 8. The outer wall of the spring 2 12 is fixedly connected to the inside of the connecting block 7. A screw head 11 is slidably connected to the outer wall of the clamping block 9. The outer wall of the screw head 11 is slidably connected to the inside of the support shell 5. A drive assembly is provided inside the housing 1. The outer shell 1 supports the hydraulic cylinder 4, and the hydraulic cylinder 4 fixes the support shell 5. The output end of the hydraulic cylinder 4 drives the support shell 5 to move, thereby causing the screw head 11 to contact the screw. The support shell 5 fixes the cylinder 6, and the cylinder 6 fixes the connecting block 7. The lower outer wall of the connecting block 7 is beveled. The connecting block 7 and the support block 8 fix the second spring 12, and the second spring 12 supports the support block 8. The connecting block 7 has a limit offset function on the support block 8. When the support block 8 moves, it slides inside the connecting block 7 and compresses the second spring 12. At the same time, the second spring 12 has a reset function on the support block 8. The outer wall of the support block 8 supports the clamping block 9. At the same time, the outer wall of the support block 8 has a groove. When the connecting block 7 moves, the screw head 11 will contact the support block 8. As the output end of the cylinder 6 drives the connecting block 7 to continue moving, the support block 8 will move inside the connecting block 7. At this time, the support block 8 will drive the clamping block 9 to move, and the clamping block 9 will be in contact with the lower side of the connecting block 7, and the connecting block 7 will press the clamping block 9. The clamping block 9 will rotate under the pressure, thereby clamping and fixing the screw head 11. The spring 10 plays a reset role for the clamping block 9. When the clamping block 9 stops rotating, it will no longer press the spring 10, and the spring 10 will return the clamping block 9 to its original position.

[0026] Please see Figure 2 As shown, the drive assembly includes a motor 2, the outer wall of which is fixedly connected to the inside of the housing 1. A rotating shaft 3 is fixedly mounted on the output end of the motor 2, and the outer wall of the rotating shaft 3 is fixedly connected to the upper surface of the hydraulic cylinder 4. The housing 1 serves to fix the motor 2, and the motor 2 serves to fix the rotating shaft 3. When the motor 2 is started, it drives the rotating shaft 3 to rotate, which in turn causes the hydraulic cylinder 4 to rotate. Furthermore, the hydraulic cylinder 4 drives the screw head 11 to tighten the bolt.

[0027] Please see Figure 1 , Figure 4and Figure 5 As shown, a support ring 13 is slidably connected to the outer wall of the outer shell 1, a limit post 14 is slidably connected inside the support ring 13, the outer wall of the limit post 14 is also connected to the inner wall of the outer shell 1, a fixing ring 15 is fixedly connected to the outer wall of the limit post 14, the outer wall of the fixing ring 15 is slidably connected to the inside of the support ring 13, a fixing handle 16 is fixedly connected to the outer wall of the fixing ring 15, and the outer wall of the fixing handle 16 is slidably connected to the inner wall of the support ring 13. The support ring 13 has two symmetrical limiting posts 14 inside. The support ring 13 supports and limits the offset of the limiting posts 14, ensuring that the limiting posts 14 can only move within the support ring 13 and will not detach from it. The outer wall of the limiting post 14 is beveled, and the outer wall of the outer shell 1 has a groove. When the support ring 13 moves within the outer wall of the outer shell 1, the outer wall of the limiting post 14 also slides within it, and the outer shell 1 presses against the limiting post 14. This pressure causes the fixing ring 15 to move. When the limiting post 14 slides into the groove on the outer wall of the outer shell 1, it clamps the outer shell 1 and prevents the support ring 13 from detaching from the outer shell 1. The upper surface of the support ring 13 has holes for moving the fixing handle 16. Pulling the fixing handle 16 causes the limiting post 14 to detach from the groove in the outer shell 1, thus achieving quick installation and disassembly.

[0028] Please see Figure 1 , Figure 4 and Figure 5 As shown, an elastic ring 17 is fitted onto the outer wall of the limiting post 14. One end of the elastic ring 17 is fixedly connected to the outer wall of the fixing ring 15, and the other end of the elastic ring 17 is fixedly connected to the right outer wall of the limiting post 14. The elastic ring 17 has a resetting function for the limiting post 14, and the fixing ring 15 and the support ring 13 have a supporting function for the elastic ring 17. When the limiting post 14 moves to the groove on the outer wall of the outer shell 1, it will slide into the groove by the elastic force of the elastic ring 17. A fixing block 18 is fixedly connected to the inner wall of the support ring 13, a spring 19 is fixedly connected to the outer wall of the fixing block 18, a limiting shell 20 is fixedly connected to the outer wall of the spring 19, a placement tube 21 is fixedly connected to the inside of the limiting shell 20, and the outer wall of the screw head 11 is slidably connected to the inner wall of the limiting shell 20.

[0029] Specifically, in this embodiment, the fixing block 18 and the limiting shell 20 support the spring 19, and the spring 19 also supports the limiting shell 20. The limiting shell 20 fixes the placement tube 21. The limiting shell 20 has holes inside, and the screw can fall into the lower outlet of the limiting shell 20 through the holes of the placement tube 21 and the limiting shell 20. At the same time, the outlet supports the screw. There is a slide between the two limiting shells 20, which can limit the movement of the screw head 11, so that the screw head 11 can accurately fit with the screw. At the same time, the outlet of the limiting shell 20 is narrower than the diameter of the screw head 11. When the screw head 11 tightens the screw, it will drive the screw to disengage from the inside of the limiting shell 20 and squeeze the outlet of the limiting shell 20. When the limiting shell 20 is squeezed, it will squeeze the spring 19, thereby causing the limiting shell 20 to rotate outward without friction with the screw head 11. The spring 19 resets the limiting shell 20.

[0030] When the device is needed, first place the required screw head 11 inside the support shell 5, then start the cylinder 6. The cylinder 6 will drive the connecting block 7 to move, and the movement of the connecting block 7 will drive the support block 8 to move. When the support block 8 moves, its lower surface will contact the screw head 11. At this time, the support block 8 will move inside the connecting block 7, and drive the clamping block 9 to contact the lower surface of the connecting block 7. The lower surface of the connecting block 7 will lubricate the clamping block 9, thereby causing the clamping block 9 to rotate, further clamping and fixing the screw head 11. After the screw head 11 is replaced, move the support ring 13 upward along the outer wall of the shell 1 and fit it on the outer wall of the shell 1. When the support ring 13 moves, the shell 1 will squeeze the limiting post 14. The limiting post 14 being squeezed will squeeze the elastic ring 17 through the fixing ring 15. The outer wall of the shell 1 has a groove. When the limiting post 14 slides into the groove, the elastic ring 17 releases elastic force on the limiting post 14, causing the outer wall of the limiting post 14 to slide into the groove, clamping and limiting the shell 1 to prevent the support ring 13 from detaching from the shell 1. Then, the screw to be tightened is placed into the inside of the limiting shell 20 through the placement tube 21. The limiting shell 20 can support the screw. Then, the motor 2 is started to drive the rotating shaft 3 to rotate, thereby tightening the screw through the screw head 11. This device can not only quickly replace the screw head 11 to adapt to the tightening of different screws, but also has a small size for easy carrying and is more flexible and convenient to use. At the same time, the limiting shell 20 for placing the screw can be quickly disassembled. The limiting shell 20 limits and supports the screw and helps the screw to align and tighten.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
