[0027] Embodiment:

[0028] Please refer to Figure 1 - Figure 8, A knurling tooling capable of quickly replacing knurling teeth, comprising a knurling column 1 and knurling teeth 2. The surface of the knurling column 1 is sleeved with the knurling teeth 2, and the knurling teeth 2 are slidably connected to the knurling column 1. A number of groups of first traction blocks 12 are welded on the mutually fitting sides of the knurling teeth 2 and the knurling column 1, and the surfaces of the first traction blocks 12 are sleeved with first traction grooves 13 opened on the knurling column 1. An installation block 3 is attached to the ends of the knurling column 1 and the knurling teeth 2, and bolts 20 penetrate through the periphery of the installation block 3. The ends of the bolts 20 are sleeved with threaded grooves 21 opened on the knurling column 1, and the threaded grooves 21 are threadedly engaged with the bolts 20. A fixing block 5 is welded to the middle of the installation block 3, and a fixing shaft 6 is welded to the middle of the fixing block 5. A limiting rod 10 is fixed to the mutually fitting side of the installation block 3 and the knurling teeth 2, and the surface of the limiting rod 10 is sleeved with a limiting groove 11 opened on the knurling column 1. When the operator needs to replace the knurling teeth 2, the operator first turns the bolts 20 to make the bolts 20 rotate in the circular through holes opened on the side penetrated by the installation block 3. And when the bolts 20 rotate, the bolts 20 are threadedly engaged with the threaded grooves 21 to move the bolts 20 out of the threaded grooves 21, and the installation block 3 is separated from the knurling column 1. Subsequently, the operator pulls the installation block 3, and the installation block 3 is removed from the end of the knurling column 1. After the knurling column 1 and the installation block 3 are separated, the operator pulls the knurling teeth 2, and the knurling teeth 2 drive the first traction blocks 12 to move, so that the first traction blocks 12 slide in the first traction grooves 13. After the first traction blocks 12 slide out of the first traction grooves 13, the knurling teeth 2 are removed from the surface of the knurling column 1, which is convenient for the operator to replace the knurling teeth 2 on the surface of the knurling column 1 and improves the convenience of replacement for the operator.

[0029] In other embodiments, gears 19 are welded to the ends of the bolts 20, and a toothed plate 4 is sleeved around the gears 19. A number of groups of teeth are provided inside the toothed plate 4, and the teeth provided inside the toothed plate 4 mesh with the teeth provided on the surface of the gears 19. The toothed plate 4 is slidably connected to the mounting block 3. Sliders 17 are welded to the sides of the toothed plate 4 and the mounting block 3 that are in contact with each other, and chutes 16 are provided on the mounting block 3 and sleeved on the surfaces of the sliders 17. A rotating sleeve 7 penetrated by a fixed shaft 6 is welded inside the toothed plate 4. When an operator needs to turn the bolt 20, the operator first holds the surface of the toothed plate 4 with the hand. The toothed plate 4 drives the slider 17 to move, and the slider 17 slides in the chute 16, so that the slider 17 and the chute 16 pull the toothed plate 4 on the surface of the mounting block 3, facilitating the stable sliding of the toothed plate 4 on the surface of the mounting block 3 and preventing the toothed plate 4 from falling off the surface of the mounting block 3 when the toothed plate 4 slides on the surface of the mounting block 3, improving the stability of the rotation of the toothed plate 4. When the toothed plate 4 moves, the teeth provided inside the inner wall of the toothed plate 4 mesh with the teeth provided on the surface of the gears 19, so that when the second traction block 14 moves, the second traction block 14 drives the gears 19 to rotate. When the gears 19 rotate, the gears 19 drive the bolts 20 to rotate in the threaded grooves 21, facilitating the convenience for the operator to turn the bolts 20.

[0030] In other embodiments, an avoidance groove 24 is opened in the middle of the fixed shaft 6, and the avoidance groove 24 is embedded with a butt plate 25, and a traction rod 23 welded on the inner wall of the avoidance groove 24 is passed through the middle of the butt plate 25, and a spring 22 is wound on the surface of the traction rod 23, and the spring 22 is respectively abutted between the inner wall of the avoidance groove 24 and the surface of the butt plate 25, and a collar 26 sleeved on the surface of the fixed shaft 6 is welded at the end of the butt plate 25, and an extension ring 27 is welded at the end of the collar 26, and the surface of the extension ring 27 is sleeved with a spring opened on the rotating shaft 6. The sleeve groove 28 on the sleeve 7, the extension ring 27 and the sleeve groove 28 are welded with a plug rod 29 on one side, and the surface of the plug rod 29 is sleeved with a slot 18 opened on the rotating sleeve 7. When the operator needs to rotate the tooth plate 4, the operator first holds the hand on the surface of the sleeve ring 26. When the operator holds the hand on the surface of the sleeve ring 26, the operator then pulls the sleeve ring 26 to move, so that the sleeve ring 26 drives the plate 25 to slide in the avoidance groove 24, and the plate 25 slides in the avoidance groove 24. The circular through hole in the middle of the push plate 25 slides on the surface of the traction rod 23, and the push plate 25 slides on the surface of the traction rod 23 through the through hole in the middle of the push plate 25, so that the push plate 25 pulls the traction rod 23. The stability of the movement of the push plate 25 is improved, and when the push plate 25 moves, the push plate 25 squeezes the spring 22, causing the spring 22 to undergo elastic deformation. After the spring 22 undergoes elastic deformation, the spring 22 avoids the push plate 25, causing the push plate 25 to slide in the avoidance groove 24, and And make the ring 26 slide on the surface of the fixed shaft 6. When the ring 26 moves, the ring 26 drives the insertion rod 29 to move through the extension ring 27, so that the extension ring 27 is moved out of the sleeve groove 28, and the extension ring 27 drives the insertion rod 29 to move out of the slot 18, so that the extension ring 27 and the insertion rod 29 no longer fix the sleeve groove 28 and the slot 18. Then the operator rotates the tooth plate 4, which is convenient for the operator to fix the tooth plate 4 when the operator no longer needs to rotate the tooth plate 4, thereby ensuring the stability of the operator's use.

[0031] In other embodiments, the second traction groove 15 is opened on the surface of the bolt 20, and the second traction block 14 welded on the inner wall of the mounting block 3 is inserted in the middle of the second traction groove 15. When the bolt 20 rotates, the bolt 20 drives the second traction groove 15 to rotate on the surface of the second traction block 14, and the bolt 20 drives the second traction groove 15 to rotate on the surface of the second traction block 14, so that when the bolt 20 rotates, it is prevented from falling off from the circular through hole opened on one side of the mounting block 3 through which the bolt 20 penetrates, thereby improving the usability of the bolt 20.

[0032] In other embodiments, a plurality of sets of positioning blocks 9 are welded to one end of the knurled column 1 away from the mounting block 3, and positioning grooves 8 opened on the knurled teeth 2 are sleeved on the surfaces of the positioning blocks 9. When the operator holds the knurled teeth 2, the knurled teeth 2 drive the positioning grooves 8 to move, so that the positioning grooves 8 are sleeved on the surfaces of the positioning blocks 9, and the positioning blocks 9 and the positioning grooves 8 position the knurled teeth 2, thereby improving the stability of the knurled teeth 2 sleeved on the surface of the knurled column 1.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
