[0022] The following examples illustrate possible implementations of this utility model, but are not intended to limit the scope of protection of this utility model. The prefixes "a" or "at least one" before the terms mentioned herein are not intended to limit the quantity. Depending on the requirements, there may also be "multiple" items. This variation in quantity is also within the scope of protection, as will be stated in advance.

[0023] Please refer to Figures 1 to 4 The present invention shows a preferred embodiment of the present invention, wherein the rotating tool 1 of the present invention includes a driving rod 10, a driven rod 20 and a steering mechanism 30.

[0024] The driven rod 20 is non-rotatably connected to a rotating component; the steering mechanism 30 includes a first pivot 31, a second pivot 32, a drive bevel gear 33, a driven bevel gear 34, and two transmission bevel gears 35. The first pivot 31 is pivotally connected to the second pivot 32. The drive bevel gear 33 is rotatably disposed on the first pivot 31 and non-rotatably connected to the drive rod 10. The driven bevel gear 34 is rotatably disposed on the second pivot 32 and non-rotatably connected to the driven rod 20. The two transmission bevel gears 35 mesh between the drive bevel gear 33 and the driven bevel gear 34. A spring abutment 36 is provided between the first pivot 31 and the drive bevel gear 33. The spring abutment 36 keeps the drive bevel gear 33 and the second transmission bevel gear 35 in normal engagement. When the spring abutment 36 is compressed and the drive bevel gear 33 disengages from the second transmission bevel gear 35, the first pivot 31 and the second pivot 32 can pivot relative to each other to adjust their angles. This allows the operating angles of the drive rod 10 and the driven rod 20 to be adjusted as needed to meet different usage requirements.

[0025] The drive bevel gear 33 includes a drive tooth portion 331 and a drive shaft portion 332. The spring abutment 36 springs against one side of the first pivot 31 between the drive tooth portion 331 and the first pivot 31. The drive shaft portion 332 protrudes from the other side of the first pivot 31 and is detachably connected to the drive rod 10, so as to facilitate the replacement of different types or sizes of the drive rod 10. The driven bevel gear 34 includes a driven tooth portion 341 and a driven shaft portion 342. The driven shaft portion 342 protrudes from the side of the second pivot 32 that is relatively away from the drive bevel gear 33 and is detachably connected to the driven rod 20, thereby allowing the replacement of different types or sizes of the driven rod 20 for assembly with tool heads such as screwdriver bits, screws, nuts, and sockets, with a wide range of applications. The drive shaft rod 332 and the drive rod 10, and the driven shaft rod 342 and the driven rod 20 can be interlocked and positioned by existing structures such as pins, fasteners or positioning balls.

[0026] In this embodiment, the second pivot 32 includes a horizontal plate 321 and two side plates 322. The driven bevel gear 34 passes through the horizontal plate 321, and the two side plates 322 are detachably assembled to the horizontal plate 321 for easy assembly. The first pivot 31 is a U-shaped plate extending from it, and is sandwiched between the two side plates 322. Each drive bevel gear 35 includes a drive tooth portion 351 and a drive shaft portion 352. The drive shaft portions 352 of the two drive bevel gears 35 are coaxially arranged, and each drive shaft portion 352 passes through and connects the first pivot 31 and the second pivot 32. Furthermore, each of the drive shaft rod portions 352 is recessed with a slot 353 and fixed to the second pivot 32 by a fastener 354 embedded in the slot 353. This allows the first pivot 31 and the second pivot 32 to smoothly pivot relative to each other to adjust the angle, facilitating assembly and providing excellent stability. The number of teeth in the drive gear portion 331, the driven gear portion 341, and each of the transmission gear portions 351 is the same, ensuring stable meshing and reliable torque transmission. In other embodiments, the number of teeth in the drive gear portion, the driven gear portion, and each of the transmission gear portions can also be adjusted as needed.

[0027] Preferably, the steering mechanism 30 further includes a bushing 37. The second pivot 32 has an annular step 323. The bushing 37 engages with the annular step 323 and surrounds the driven bevel gear 34. The bushing 37 can be selected to have low frictional resistance with the driven bevel gear 34, avoiding direct contact between the driven bevel gear 34 and the second pivot 32 and thus preventing frictional resistance, ensuring that the driven bevel gear 34 can be smoothly driven. One of the first pivot 31 and the second pivot 32 has at least one limiting locking portion 324, which can interfere with and block the other of the first pivot 31 and the second pivot 32. For example, each side plate 322 has one limiting locking portion 324, which can interfere with and block the first pivot 31 to limit the angle of swing of the first pivot 31 relative to the second pivot 32, avoiding excessive pivoting.

[0028] Reference Figure 4 During operation, the drive rod 10 can be pulled away from the steering mechanism 30, thereby causing the drive bevel gear 33 to compress the spring abutment 36 and disengage from the second transmission bevel gear 35. This allows the first pivot 31 and the second pivot 32 to pivot relative to each other to adjust the operating angle. Then, the drive rod 10 is released, and the spring abutment 36 drives the drive bevel gear 33 to move towards and engage with the second transmission bevel gear 35. The structure is simple, easy to operate, and provides stable and smooth operation. The drive rod 10 can be rotated manually or by connecting a power tool, thereby driving the drive bevel gear 33 to rotate in conjunction with the second transmission bevel gear 35 and the driven bevel gear 34, thus transmitting torque to achieve the purpose of fastening.

[0029] In another preferred embodiment, the rotating tool 1 further includes a kit 40, which is fitted around the outer periphery of the driven rod 20 and includes a locking connector 41. The locking connector 41 is locked onto the second pivot 32 without relative rotation. The driven rod 20 protrudes from one end of the kit 40 relative to the locking connector 41, thereby allowing the kit 40 to be held by the user to increase stability during operation. The kit 40 has a radial flange 42 at one end relative to the locking connector 41 to prevent the user's hand from accidentally moving onto the driven rod 20, ensuring good operational safety. There is a gap between the inner peripheral surface of the kit 40 and the outer peripheral surface of the driven rod 20, allowing the driven rod 20 to rotate smoothly.

[0030] The above description is a preferred embodiment of the present utility model and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solution of the present utility model without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
