[0024] The embodiment of the present application provides a bendable screwdriver rod, which effectively solves the problem that the above-mentioned device increases the torsional force by plugging and gripping, but requires additional carrying and storage during work, which reduces the portability of the tool. In particular, it is more likely to be lost in work environments that require frequent movement. When screwing the screws, the second tool rod can be rotated with the rotating shaft as the center of the circle. During the rotation of the second tool rod, the first connecting rod and the second connecting rod are rotated to provide limit support for the second tool rod. The second tool rod is rotated ninety degrees to adjust its position, thereby increasing the torsional force on the screw. In this way, large or high-tightness screws can be driven more easily without adding or using tools for operation, thus saving the steps of finding, carrying and using additional tools, and helping to improve operating comfort and work efficiency.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the above-mentioned device increases the torsional force by plugging and holding, but needs to be carried and stored additionally during work, which reduces the portability of the tool, especially in work situations where frequent movement is required, and it is more likely to be lost. The overall idea is as follows: it includes a first knife bar 11, the first knife bar 11 is rotatably connected to a rotating shaft 12, the outer surface of the rotating shaft 12 is sleeved with a second knife bar 13, one side of the first knife bar 11 and the second knife bar 13 are fixedly connected to a connecting block 14, the two connecting blocks 14 are rotatably connected to a first connecting rod 15, and the first connecting rod 15 The outer surface is rotatably connected to a second connecting rod 16, which is rotatably connected to the inside of the second cutting rod 13. When screwing a screw, the second cutting rod 13 can be rotated around the rotating shaft 12 as the center. During the rotation of the second cutting rod 13, the first connecting rod 15 and the second connecting rod 16 are used to limit the rotation of the second cutting rod 13. The second cutting rod 13 is rotated ninety degrees to adjust the position, thereby increasing the torsional force on the screw. This makes it easier to drive large or high-tightness screws without adding or using tools for operation, thus saving the steps of finding, carrying and using additional tools, and is conducive to improving operating comfort and work efficiency.

[0027] A positioning mechanism is fixedly connected inside the second tool rod 13, and the positioning mechanism includes a positioning block 17. The positioning block 17 is fixedly connected inside the second tool rod 13. A positioning groove 18 is opened inside the first tool rod 11, and the positioning block 17 and the positioning groove 18 are adapted to each other. A magnetic block 19 is sleeved inside the first tool rod 11, and a cutter head 21 is sleeved inside the first tool rod 11. The cutter head 21 is sleeved inside the magnetic block 19. When the second tool rod 13 rotates and resets, it rotates into the positioning groove 18 through the positioning block 17, providing an exact stopping point, so that the handle can accurately return to its original position, ensuring the stability and reliability of the tool during operation, and the cutter head 21 is sleeved into the first tool rod 11, and the cutter head 21 is fixed by the magnetic block 19, and the cutter head 21 is fitted with the screw to be screwed, and the first tool rod 11 is screwed to tighten or loosen the screw. The types of the two ends of the cutter head 21 are different. By changing the direction of the cutter head 21, different types of cutter heads 21 can also be replaced to adapt to different types of screws.

[0028] A rotating ring 22 is rotatably connected inside the first knife rod 11, and a handle 23 is fixedly connected to the outer surface of the rotating ring 22. Two arc grooves 24 are provided inside the rotating ring 22. Two clamping blocks 25 are slidably connected inside the first knife rod 11. The two clamping blocks 25 are respectively sleeved inside the two arc grooves 24. The two clamping blocks 25 are on the same horizontal line with the magnetic block 19. When the cutter head 21 is installed, the handle 23 can be rotated on the basis of the magnetic block 19 adsorbing and fixing the cutter head 21. The handle 23 drives the rotating ring 22 to rotate inside the first knife rod 11. During the rotation of the rotating ring 22, the clamping blocks 25 are squeezed through the arc grooves 24 to cause sliding. The two sides of the cutter head 21 are squeezed and fixed by sliding of the clamping blocks 25. Different fixing methods can be rotated according to the working scene. The two clamping blocks 25 slide and squeeze the cutter head 21 to make the fixing effect more stable and reliable, which improves the stability and safety of the work.

[0029] In view of the problems existing in the prior art, the utility model provides a flexible screwdriver rod. When tightening the screw, the second rod 13 can be rotated with the rotating shaft 12 as the center. During the rotation of the second rod 13, the first connecting rod 15 and the second connecting rod 16 are rotated to limit the support. The second rod 13 is rotated ninety degrees to adjust the position, thereby increasing the torsional force on the screw. In this way, large or high-tightness screws can be driven more easily without adding or using tools for operation, saving the steps of finding, carrying and using additional tools, which is conducive to improving operating comfort and work efficiency.

[0030] Working principle:

[0031] The first step is to insert the cutter head 21 into the first cutter bar 11, fix the cutter head 21 by adsorbing the magnetic block 19, fit the cutter head 21 to the screw to be screwed, and screw the first cutter bar 11 to tighten or loosen the screw. The two ends of the cutter head 21 are of different types. By changing the direction of the cutter head 21, cutter heads 21 of different types can also be replaced to adapt to different types of screws. When screwing the screw, the second cutter bar 13 can be rotated with the rotating shaft 12 as the center. During the rotation of the second cutter bar 13, the first connecting rod 15 and the second connecting rod 16 are rotated to limit and support it. The second cutter bar 13 is rotated ninety degrees to adjust the position to increase the torsional force on the screw. In this way, large or high-tightness screws can be driven more easily without adding or using tools for operation, saving the steps of finding, carrying and using additional tools, which is conducive to improving operating comfort and work efficiency. When the second cutter bar 13 rotates and resets, it rotates into the positioning groove 18 through the positioning block 17 to provide an exact stop point, so that the handle can accurately return to its original position, ensuring the stability and reliability of the tool during operation.

[0032] In the second step, when the cutter head 21 is installed, the handle 23 can be rotated on the basis of the magnetic block 19 adsorbing and fixing the cutter head 21. The handle 23 drives the rotating ring 22 to rotate in the first cutter rod 11. During the rotation of the rotating ring 22, the arc groove 24 squeezes the clamping block 25 to cause sliding. The two sides of the cutter head 21 are squeezed and fixed by sliding of the clamping block 25. Different fixing methods can be rotated according to the working scene. The two clamping blocks 25 slide and squeeze the cutter head 21 to make the fixing effect more stable and reliable, thereby improving the stability and safety of the work.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
