[0025] The specific operation is as follows. The staff snap-fits the slitting tool 3 with the limit rod 2 so that the slitting tool 3 is sleeved on the rear side of the installation base 1. Then, the snap ring 4 is slightly expanded and snap-fitted on the outside of the installation base 1, and one end of the snap ring 4 is snap-fitted with the limit rod 2. Next, the staff snap-fits and sleeved the spring coil 6 between the limit ring 5 and the slitting tool 3 so that the spring coil 6 provides a certain elastic support for the slitting tool 3. The installation base 1 is sleeved and installed, and the bolt 7 can be adjusted to fix the installation base 1, avoiding the situation of deviation and dropping during subsequent processing. The structure is simple and convenient for the staff to use the slitting knife.

[0026] AsFigure 1 , Figure 4 and Figure 5 As shown in ,

[0027] , the limit block 8 is arranged at the edge of the mounting base 1, and an adjusting component 9 is arranged between the limit block 8 and the mounting base 1. The adjusting component 9 includes a rotating part 901, a connecting rod 902, a limit rotating rod 903, bevel gears 904, a bidirectional screw 905, a limiting part 906, a movable block 907, a movable rod 908 and an arc-shaped block 909. The rotating part 901 is arranged inside the mounting base 1, and a connecting rod 902 is welded to the center of one side of the rotating part 901. A limit rotating rod 903 is welded to the center of one end of the connecting rod 902, and the end of the limit rotating rod 903 is rotationally connected to the mounting base 1 in a snap-fit manner. Fixed blocks 10 are rotatably connected to the outer sides of both ends of the connecting rod 902, and one side of the fixed block 10 is fixedly connected to the mounting base 1. Bevel gears 904 are fixedly connected to the outer walls of both ends of the connecting rod 902. The connecting rod 902 is rotationally connected to a bidirectional screw 905 through the bevel gears 904. Both ends and the middle section of the bidirectional screw 905 penetrate through and are connected to a fixing plate 11, and one side of the fixing plate 11 is welded to the mounting base 1.

[0027] The specific operation is as follows. After the staff fixes and installs the mounting base 1, the staff can adjust the processing depth of the slitting knife according to the actual situation. The staff rotates the rotating part 901, so that the connecting rod 902 welded to the center of one side thereof and the limit rotating rod 903 welded to the center of one side of the connecting rod 902 rotate accordingly. Under the action of the bevel gears 904, the bidirectional screw 905 rotates accordingly. As the bidirectional screw 905 rotates, the movable blocks 907 rotatably connected to its outer side move, and the movable rod 908 rotatably connected between the movable blocks 907 rotates, so that the limit block 8 rotationally connected to the end of the movable rod 908 through the arc-shaped block 909 moves outward, so that the processing depth of the slitting tool 3 for the workpiece to be processed is changed, and the workpiece is limited to a certain extent. The structure is simple, which is convenient for the staff to use the slitting knife.

[0028] In summary, for the slitting knife with a depth limit function, according to Figures 1 - 5In the structure shown in the figure, during the use of the slitting knife, first, the staff engages the slitting tool 3 with the limiting rod 2, so that the slitting tool 3 is sleeved on the rear side of the mounting base 1. Then, the snap ring 4 is slightly expanded and engaged on the outside of the mounting base 1, and one end of the snap ring 4 is engaged with the limiting rod 2. Next, the staff engages and sleeves the spring coil 6 between the limiting ring 5 and the slitting tool 3, so that the spring coil 6 provides a certain elastic support for the slitting tool 3. The mounting base 1 is sleeved and installed, and the adjusting bolt 7 is adjusted to fix the mounting base 1. Then, the staff rotates the rotating member 901 in the adjusting assembly 9, so that the connecting rod 902 welded to the center of one side thereof and the limiting rotating rod 903 welded to the center of one side of the connecting rod 902 rotate accordingly. Under the action of the bevel gear 904, the bidirectional screw rod 905 rotates accordingly. As the bidirectional screw rod 905 rotates, the movable block 907 rotatably connected to the outside thereof moves, and the movable rod 908 rotatably connected between the movable blocks 907 rotates, so that the limiting block 8 rotatably connected to the end of the movable rod 908 through the arc-shaped block 909 moves outward, thereby changing the machining depth of the slitting tool 3 for the workpiece to be machined, which is convenient for the staff to use the slitting knife for machining.
