Description

Rotating tool This invention relates to rotating tools, and more particularly to a rotating tool with an adjustable operating angle. Conventional rotating tools, such as screwdrivers and tool extensions, can be hand-held and rotated to lock or release screws. These include steerable rotating tools, whose handles and working ends can be adjusted at relative angles, making it easy to perform locking operations in different operating environments. However, existing steerable rotary tools have complex structures, are difficult to manufacture, resulting in high prices, and are prone to failure or parts wear during use. They also have poor torque transmission, operational stability, and smoothness, and there are shortcomings that urgently need to be improved. Therefore, it is necessary to provide a novel and progressive rotary tool to solve the above-mentioned problems. The main objective of this invention is to provide a rotating tool that is steerable, has a simple structure, and operates stably and smoothly. To achieve the above objectives, the present invention provides a rotating tool, comprising: a drive rod, a driven rod, and a steering mechanism. The driven rod is non-rotatably connected to a rotating component; the steering mechanism includes a first pivot, a second pivot, a drive bevel gear, a driven bevel gear, and two transmission bevel gears. The first pivot and the second pivot are pivotally connected. The drive bevel gear is rotatably disposed on the first pivot and non-rotatably connected to the drive rod. The driven bevel gear is rotatably disposed on the second pivot and non-rotatably connected to the driven rod. The two transmission bevel gears mesh between the drive bevel gear and the driven bevel gear. A spring-loaded member is further provided between the first pivot and the drive bevel gear, which keeps the drive bevel gear and the two transmission bevel gears normally engaged. When the spring-loaded member is compressed and the drive bevel gear disengages from the two transmission bevel gears, the first pivot and the second pivot can pivot relative to each other to adjust their angle. The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The use of "a" or "at least one" before the terms mentioned herein is not a limitation on the quantity, and may also be "multiple" depending on the requirements. Such variations in quantity are also within the scope of protection, and are therefore stated in advance. Please refer to Figures 1 to 4, which show a preferred embodiment of the present invention. The rotating tool 1 of the present invention includes a drive rod 10, a driven rod 20 and a steering mechanism 30. 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. In this way, the operating angles of the drive rod 10 and the driven rod 20 can be adjusted as needed to meet different usage requirements. 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 drive shaft portion 332. 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 332 and the drive rod 10, and the driven shaft 342 and the driven rod 20 can be interlocked and positioned by existing structures such as pins, fasteners or positioning balls. 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 the horizontal plate, and the first pivot 31 is sandwiched between the two side plates 322. Each transmission bevel gear 35 includes a transmission tooth portion 351 and a transmission shaft portion 352. The transmission shaft portions 352 of the two transmission bevel gears 35 are arranged opposite each other in an axial direction and are not connected. Each transmission shaft portion 352 passes through and connects the first pivot 31 and the second pivot 32. When the drive rod 10 drives the drive bevel gear 33 to rotate, the two transmission bevel gears 35 are each driven independently by the drive bevel gear 33, and together drive the driven bevel gear 34 to rotate. In this way, the two transmission bevel gears 35 can adjust their positions slightly when the pivot angle changes, so as to stably mesh with the drive bevel gear 33 and the driven bevel gear 34, avoiding tooth misalignment caused by pivoting. In addition, the two transmission bevel gears 35 can distribute the output torque of the drive bevel gear 33, improve the overall transmission strength and durability, and reduce the volume of the pivot structure, achieving the effects of high strength, low loss, and long service life. Furthermore, each transmission shaft rod portion 352 is recessed with a slot 353 and fixed to the second pivot seat 32 by a fastener 354 embedded in the slot 353. In this way, the first pivot seat 31 and the second pivot seat 32 can smoothly pivot relative to each other to adjust the angle, which is convenient for assembly and has good stability. The number of teeth of the drive gear portion 331, the driven gear portion 341 and each transmission gear portion 351 is the same, which can stably mesh and reliably transmit torque. In other embodiments, the number of teeth of the driving tooth, the driven tooth, and each of the transmission teeth can also be adjusted and configured as needed. 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. Referring to 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, releasing the drive rod 10 causes the spring abutment 36 to move the drive bevel gear 33 toward 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 causing 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. 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 opposite 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 opposite 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. 1: Rotating tool 10: Drive rod 20: Driven rod 30: Steering mechanism 31: First pivot 32: Second pivot 321: Horizontal plate 322: Side plate 323: Ring step 324: Limiting latch 33: Drive bevel gear 331: Drive gear 332: Drive shaft 34: Driven bevel gear 341: Driven gear 342: Driven shaft 35: Transmission bevel gear 351: Transmission gear 352: Transmission shaft 353: Slot 354: Fastener 36: Spring abutment 37: Bushing 40: Kit 41: Snap-fit ​​connector 42: Radial flange Figure 1 is a perspective view of a preferred embodiment of the present invention.
