[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] See also Figure 1-5 The utility model provides a technical solution: a tool for a duck foot ligament cutting device, comprising a mounting handle 1 and a handle 4, a cutting knife 5 is fixedly connected to the lower end of the handle 4, the top of the mounting handle 1 is fixedly connected to the cutting output end of the cutting device, a ring block 7 is fixedly connected to the top of the handle 4, a ring cavity 2 is opened at the mounting handle 1 corresponding to the ring cavity 2, the ring block 7 is slidably connected in the ring cavity 2, a column cavity 3 is opened in the mounting handle 1, three mounting cavities 10 are opened on the inner side wall of the column cavity 3, and a locking rod 11 is slidably connected in the mounting cavity 10 A locking hole 21 is provided at the locking rod 11 corresponding to the ring block 7, one end of the locking rod 11 is fixedly connected to the extrusion block 13, and the other end of the locking rod 11 is slidably connected to the locking hole 21 corresponding to the ring block 7, and a top column 8 is slidably connected to the column cavity 3, and the outer wall of the top column 8 is against the column cavity 3. A locking cancellation structure and an automatic locking structure are provided in the column cavity 3. By providing the locking structure and the automatic locking structure, the operation steps for replacing the cutting knife 5 are slowed down, the operation of replacing the cutting knife 5 is simple and quick, and the efficiency of tool replacement is improved.

[0025] like Figure 1-5 As shown, the locking cancellation structure includes an iron chain 14 fixedly connected to the top column 8, the iron chain 14 is slidably connected in the mounting handle 1, the end of the iron chain 14 away from the top column 8 passes through the outer wall of the mounting handle 1, and a compression spring 12 is fixedly connected in the mounting cavity 10, and the compression spring 12 is fixedly connected to the extrusion block 13. By setting the iron chain 14, the function of pulling the iron chain 14 to cancel the limitation of the extrusion block 13 is achieved, and by setting the compression spring 12, the locking rod 11 is made to slide out of the locking hole 21.

[0026] like Figure 1-5 As shown, the automatic locking structure includes a reset spring 9 inside the column cavity 3, and the reset spring 9 is fixedly connected to the top column 8. By setting the reset spring 9, other components in the device can be reset.

[0027] like Figure 1-5 As shown, the extrusion block 13 is in the shape of a semicircular arc block. When the inclined surface of the extrusion block 13 is extruded, it can move away from the extrusion source.

[0028] like Figure 1-5 As shown, one end of the iron rope 14 away from the top column 8 is fixedly connected to a mounting plate 15, and a handle 16 is fixedly connected to the mounting plate 15. By providing the handle 16, it is convenient for the staff to pull the iron rope 14, thereby optimizing the user experience.

[0029] like Figure 1-5 As shown, a mounting block 6 is fixedly connected to the top of the handle 4 corresponding to the column cavity 3, and three positioning blocks 22 are fixedly connected to the outer wall of the mounting block 6. Positioning grooves 20 are provided at the column cavity 3 corresponding to the positioning blocks 22. The positioning blocks 22 are slidably connected in their corresponding positioning grooves 20. The positioning grooves 20 are provided to play a positioning role, thereby preventing the column cavity 3 and the locking rod 11 from being unable to align.

[0030] like Figure 1-5 As shown, a rubber extrusion pad 19 is fixedly connected to the bottom surface of the mounting handle 1. By providing the rubber extrusion pad 19, the impact of the collision and shaking of the cutting knife 5 during operation on the mounting handle 1 is reduced, thereby increasing the service life of the mounting handle 1.

[0031] like Figure 1-5 As shown, a flange 17 is fixedly connected to the top of the mounting handle 1, and a plurality of mounting holes 18 are provided on the flange 17, so that the mounting handle 1 can be fixedly mounted through the flange 17.

[0032] Working principle: After the cutter is installed on the cutting device through the flange 17, when the cutter of the cutting device is replaced, the handle 16 is pulled to pull the top column 8 through the iron rope 14. After the top column 8 moves, it no longer blocks the extrusion block 13, and the compression spring 12 set in the installation cavity 10 is no longer compressed to restore the deformation. The extrusion block 13 is deformed by the compression spring 12 to drive the locking rod 11 to retract into the installation cavity 10, thereby canceling the locking effect of the ring block 7, so that the handle 4 can be taken out after pulling the handle 16, and the used cutting knife 5 can be replaced;

[0033] When installing the cutting knife 5, the ring block 7 is inserted into the ring cavity 2 while pulling the handle 16, and the knife handle 4 is rotated so that the positioning block 22 is aligned with the positioning groove 20. At this time, the knife handle 4 can continue to be pushed, and the locking rod 11 can be aligned with the locking hole 21 through the positioning block 22 cooperating with the positioning groove 20, and then the knife handle 4 is pushed until it cannot move. After releasing the handle 16, the reset spring 9 is restored and deformed, and the top column 8 is pushed to move. The top column 8 squeezes the squeezing block 13. The squeezing block 13 is a semicircular arc block. When the inclined surface of the squeezing block 13 is squeezed, it can be moved away from the top column 8, so that the top column 8 squeezes the squeezing block 13 into the installation cavity 10 when squeezing the squeezing block 13. When the squeezing block 13 moves, it drives the locking rod 11 to insert into the locking hole 21, and the cutting knife 5 can be locked. When the cutting knife 5 is replaced, the operation is simple and fast, and the efficiency of tool replacement is improved.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
