DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Reference Figure 1-3 As shown, a ball knife rod suitable for multiple scenarios includes a knife handle 1, a knife seat 2 and a knife rod 3. The knife seat 2 is vertically fixed on one side of the knife handle 1, and a mounting seat 4 is provided at the bottom of the knife seat 2. Mounting rods 5 are symmetrically extended on both sides of the mounting seat 4. The knife rod 3 is sleeved on the mounting rod 5. A through groove 6 for the mounting rod 5 to pass through is horizontally opened at the top of the knife rod 3. A rotating mechanism that can drive the mounting seat 4 to rotate is provided inside the knife seat 2, and a first locking mechanism that can lock the knife rod 3 and the mounting rod 5 is provided on the knife handle 1. A second locking mechanism that can lock the knife handle 1 and the knife rod 3 is provided on the knife handle 1.

[0019] Furthermore, the rotating mechanism includes a driving bevel gear 7, a driven bevel gear 8, a rotating rod 9 and a connecting rod 10. The rotating rod 9 is fixedly vertically set on the top of the mounting seat 4, the driven bevel gear 8 is fixedly sleeved on the rod body of the rotating rod 9, the driving bevel gear 7 is fixedly sleeved on one end of the connecting rod 10 and meshes with the driven bevel gear 8, and the other end of the connecting rod 10 passes through the tool holder 2 to the outside of the tool holder 2 and is fixedly provided with a rotating handle 11.

[0020] Furthermore, a limiting ring 12 is fixedly provided on the bottom end of the rotating rod 9, and a limiting plate 13 is provided on the inner bottom end of the knife seat 2. The limiting ring 12 is arranged above the limiting plate 13 and the limiting plate 13 can support the limiting ring 12 to prevent the rotating rod 9 from falling off from the knife seat 2.

[0021] Furthermore, the first locking mechanism includes a first threaded hole 14, a second threaded hole 15 and a screw. The first threaded hole 14 is opened on the surface of the mounting rod 5, and the second threaded hole 15 is opened on the surface of the tool rod 3 and passes through the tool rod 3 to communicate with the through groove 6 inside the tool rod 3. The second threaded hole 15 includes two groups, which are symmetrically arranged on the surface and back of the tool rod 3. The screw can pass through the second threaded hole 15 on the surface of the tool rod 3 and be threaded into the first threaded hole 14 on the surface of the mounting rod 5 so that the tool rod 3 can be fixed on the mounting rod 5. When the tool on the spare tool rod 3 is not needed, the tool rod 3 can be rotated to point the tool upward, and then the screw is passed through the second threaded hole 15 on the back of the tool rod 3 to fix the tool rod 3. This can prevent the tool on the spare tool rod from affecting the normal use of the tool on the main tool rod due to being on the same horizontal plane as the tool on the main tool rod.

[0022] Furthermore, the second locking mechanism includes a fixing rod 16, a through groove 17, a control groove 18, an installation groove 19, a third threaded hole 20 and a toggle rod 21. The through groove 17 is vertically opened at the bottom center of the shank 1, the installation groove 19 is opened at the top of the shank 3 and the installation groove 19 corresponds to the opening of the through groove 17. The fixing rod 16 is slidably set in the through groove 17 to move up and down. The size of the fixing rod 16 is consistent with the through groove 17 and the installation groove 19. The control groove 18 is opened on the handle body surface of the shank 1 and is connected to the through groove 17. The toggle rod 21 is vertically set at the top of the fixing rod 16 and the toggle rod 21 is set in the control groove 18. The third threaded hole 20 is set at the top of the fixing rod 16 and is located above the toggle rod 21. The third threaded hole 20 is threaded with a screw, which passes through the fixing rod 16 and is threaded with the inside of the shank 1.

[0023] In the embodiment of this utility model, please refer to Figure 1-Figure 3When the operator finds that the ball cutter is severely worn and not suitable for continuing cutting work, he uses a screw gun to remove the screw in the second threaded hole 15 on the working tool rod 3 below the tool handle 1. At this time, the first locking mechanism is unlocked, so that the tool rod 3 can rotate freely on the mounting rod 5. At this time, the screw gun is aimed at the third threaded hole 20 on the fixing rod 16 in the control groove 18 on the tool handle 1. After removing the screw in the third threaded hole 20, the fixing rod 16 can slide up and down in the through groove 17. At this time, the worker only needs to push the toggle rod 21 upward to remove the fixing rod 16 from the mounting groove 19 on the tool rod 3 to unlock the second locking mechanism. The tool bar 3 can be rotated freely on the horizontal plane through the mounting seat 4. At this time, the worker rotates the rotating handle 11 set on the outside of the tool seat 2 to control the active bevel gear 7 to drive the driven bevel gear 8, thereby driving the rotating rod 9 to rotate in the tool seat 2. The rotating rod 9 then drives the mounting seat 4 and the mounting rod 5 to rotate. At this time, the spare tool bar 3 is rotated to the bottom of the tool handle 1, and then the screw is driven into the first threaded hole 14 on the surface of the mounting rod 5 through the second threaded hole 15. At this time, the first locking mechanism is completed, so that the tool bar 3 and the mounting rod 5 are fixed to prevent the tool from being locked. If the rod 3 moves, align the mounting slot 19 on the top of the tool bar 3 with the through slot 17 at the center of its bottom. Insert the fixing rod 16 in the through slot 17 into the mounting slot 19 on the top of the tool bar 3. Then, drive a screw into the third threaded hole 20 exposed in the control slot 18. The screw passes through the third threaded hole 20 and is driven into the interior of the tool handle 1, allowing the fixing rod 16 to engage with the mounting slot 19. This completes the second locking mechanism, securing the tool handle 1 to the tool bar 3 and preventing horizontal movement of the tool bar 3 during operation. The spare tool bar 3 can then be used to continue working, improving efficiency. During the cutting process, different cutting depths require different ball cutters. Workers can prepare a primary ball cutter and a secondary ball cutter in advance, each mounted on the primary and secondary tool bars. When a certain cutting depth is completed, the worker can quickly switch to the second ball cutter. This reduces downtime and improves work efficiency while also allowing for advance preparation and preventing workers from misusing other tools.
