[0002] Disposable tools, also known as machine-clamped or indexable tools, are a combination of a tool bar and a blade. The characteristic of this type of tool is that the tool bar has a long service life. When the tool is damaged, it can be reused by simply replacing the blade, which can greatly reduce the customer's manufacturing cost. In addition, disposable tools can be designed in various forms according to different customer products, such as tool holder replacement or blade adjustment to ensure the maximum life and optimal performance of the tool. In modern industrial production, disposable tools have become an indispensable part of the production and processing process due to their low cost and high efficiency.

[0003] For example, the authorization announcement number CN215702495U discloses a disposable blade that is easy to remove chips. A first chip removal guide groove and a second chip removal guide groove are respectively arranged on the upper and lower outer surfaces of the connection between the blade connecting sleeve and the blade cutting section. The first chip removal guide groove and the second chip removal guide groove can be used to remove wood chips generated during the wood cutting process in the blade cutting section; by setting the two side edges of the blade cutting section as an upper cutting edge and a lower cutting edge, respectively, the upper cutting edge is inclined upward and the lower cutting edge is inclined downward, so that the blade has two different processing methods, and the tool rod can be held to push forward or pull backward, which effectively improves the operational flexibility of the blade and thus effectively improves the practicality of the blade; through the setting of the connecting block, the connecting bolt, the adjusting notch and the adjusting groove, the relative position of the blade connecting tube and the connecting block can be conveniently adjusted, and then the length of the entire blade can be adjusted, which is convenient to operate and highly practical.

[0004] Since this blade has the function of adjustable length, the cost of the blade is higher than that of traditional blades.

DETAILED DESCRIPTION

[0022] Reference Figures 1 to 4 The utility model is further described in detail.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] The disposable blade comprises a main body 1 and a blade portion 2. The main body 1 comprises a detachably connected sleeve 3 and a connecting pipe 4. The end surface of the sleeve 3 is provided with a mounting hole for the connecting section 8 to extend into, so as to adjust the length of the blade.

[0026] The side wall of the sleeve 3 is provided with a mounting groove 5 , and the upper and lower inner walls of the mounting groove 5 are both provided with a plurality of convex teeth 6 arranged at equal intervals, and a connecting groove is formed between two adjacent convex teeth 6 for connecting with the blade 2 .

[0027] The blade 2 includes a cutting section 7 and a connecting section 8. The upper and lower end surfaces of the cutting section 7 both have cutting edges. A connecting rod 9 is provided between the cutting edge and the cutting section 7. The connecting rod 9 is welded to the cutting edge to support the cutting edge and increase its stability.

[0028] A reinforcing structure 10 is provided inside the cutting segment 7, and the reinforcing structure 10 includes a plurality of groups of cross-arranged reinforcing ribs 15. The interior of the reinforcing ribs 15 is hollow, and shock-absorbing blocks 16 are filled between two adjacent groups of reinforcing ribs 15. The shock-absorbing blocks 16 are preferably made of rubber material, which increases the structural strength of the cutting segment 7. The shock-absorbing blocks 16 can reduce shock to the cutting segment 7 and absorb the force brought about during the cutting process, thereby reducing damage to the cutting segment 7.

[0029] The upper and lower end surfaces of the connecting section 8 are provided with a plurality of convex teeth 11 arranged at equal intervals. The position of the convex teeth 11 corresponds to the connecting groove, and the convex teeth 11 extend into the connecting groove. The outer wall of the convex teeth 11 abuts against the outer wall of the convex teeth 1 6.

[0030] A docking groove 12 is provided on the side wall of the connecting section 8, and a connecting piece 13 for fixing the connecting section 8 and the sleeve 3 is provided in the docking groove 12. The connecting piece 13 is provided with an insert 14 for extending into the docking groove 12. There are two connecting pieces 13, and the two connecting pieces 13 are respectively placed on both sides of the connecting section 8. The connecting piece 13 has a plate body 17 covering the connecting section 8. The inner wall of the plate body 17 is provided with a convex tooth three 19 that contacts the connecting section 8. The convex tooth three 19 is integrally formed with the plate body 17. The convex tooth three 19 contacts the connecting section 8, thereby further increasing the connection between the blade 2 and the sleeve 3.

[0031] A screw rod 18 is provided on the plate body 17, and the screw rod 18 passes through the plate body 17 and the mounting hole, so that the end of the screw rod 18 abuts against the connecting section 8, and the connecting section 8 is fixed in the mounting groove 5. The connecting section 8 and the cutting section 7 are integrally formed, thereby realizing the connection between the blade 2 and the sleeve 3.

[0032] Working principle: When in use, slide the connecting section 8 from the side wall of the sleeve 3 into the installation groove 5, and make the convex tooth 2 11 dock with the connecting groove. Since the convex tooth 2 11 is meshed with the convex tooth 1 6, during the cutting process, the front and rear push and pull cannot separate the connecting section 8 from the sleeve 3, and then insert the insert 14 into the docking groove 12, and then tighten the screw 18 on the plate body 17 so that the screw 18 is in conflict with the cutting section 7. At the same time, the convex tooth 3 19 is in conflict with the outer wall of the connecting section 8, which increases the connection tightness of the connecting member 13 to the connecting section 8. After installation, in the horizontal direction, the convex tooth 1 6 is meshed with the convex tooth 2 11, so that the connecting section 8 cannot be separated from the sleeve 3, and in the longitudinal direction, the connecting member 13 blocks the notch of the installation groove 5, so that the connecting section 8 cannot slide out of the installation groove 5, thereby realizing the detachable connection between the blade 2 and the sleeve 3.

[0033] When the blade 2 needs to be replaced, the connecting piece 13 is taken out by unscrewing the screw 18, and then the connecting section 8 is slid out of the mounting groove 5. Finally, the new blade 2 can be installed according to the above steps, thereby realizing the quick disassembly and quick installation of the disposable blade blade 2 and the main body 1.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
