[0017] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:

[0018] Please refer to Figures 1 to 3 A door frame knife includes a knife body 10, which is disc-shaped. A first slot 20 is provided on the outer circumference of the knife body 10. A first blade 30 and a first pressure block 31 are inserted into the first slot 20. The first blade 30 is fixed in the first slot 20 by the first pressure block 31, and one end of the first blade 30 extends to the side of the knife body 10. A second slot 40 is provided on the side of the knife body 10. A second blade 50 and a second pressure block 51 are inserted into the second slot 40. The second blade 50 is fixed in the second slot 40 by the second pressure block 51, and one end of the second blade 50 extends to the outer circumference of the knife body 10.

[0019] In the above solution, the first blade 30 is fixed in the first slot 20 by the first pressure block 31, and the second blade 50 is fixed in the second slot 40 by the second pressure block 51. The first blade 30 and the second blade 50 are both easy to replace, and the cutter body 10 is reusable, which saves costs. Moreover, when the blade breaks, the pressure block supports the entire blade, which can prevent the blade from flying and injuring people, thus providing high safety performance. In addition, one end of the first blade 30 extends to the side of the cutter body 10, and one end of the second blade 50 extends to the outer peripheral surface of the cutter body 10, so that the working area of the first blade 30 and the working area of the second blade 50 partially intersect, ensuring that a complete product can be processed. At the same time, the two blades are used for staggered cutting, which makes the cut surface smoother, the cutting easier, and reduces the machine load.

[0020] Please refer to Figure 1 and Figure 3 A knife groove 21 is provided on the side of the first card slot 20, and the first blade 30 is inserted into the knife groove 21. The side of the first pressure block 31 away from the first blade 30 abuts against the side of the first card slot 20, the sides of the first blade 30 and the first pressure block 31 close to each other abut against each other, and the side of the first blade 30 away from the first pressure block 31 abuts against the side of the knife groove 21.

[0021] In the above scheme, the first blade 30 is inserted into the blade groove 21, and is positioned and limited by the blade groove 21. Then the first pressure block 31 is inserted into the first card slot 20 to lock the first blade 30. It is easy to disassemble and assemble, and the blade body 10 can be reused, which saves costs. The first pressure block 31 presses against the entire first blade 30, which can prevent the first blade 30 from splashing and injuring people when it breaks, and has high safety performance.

[0022] Please refer to Figure 1 and Figure 3 The side of the second pressure block 51 away from the second blade 50 abuts against the side of the second slot 40, the sides of the second blade 50 and the second pressure block 51 that are close to each other abut against each other, and the side of the second blade 50 away from the second pressure block 51 abuts against the other side of the second slot 40. Furthermore, a threaded through-hole 41 is defined on the side of the second slot 40 corresponding to the second pressure block. A locking screw is inserted into the threaded through-hole 41, and one end of the locking screw abuts against the side of the second pressure block 51. A mounting slot 42 is defined on the blade body 10 at a position corresponding to the threaded through-hole 41.

[0023] In the above embodiment, the second blade 50 and the second pressure block 51 are inserted into the second slot 40, and the second pressure block 51 is used to lock the second blade 50. The second pressure block 51 is also fixed by a locking screw, which facilitates disassembly and assembly, and the blade body 10 is reusable, saving costs. In addition, the second pressure block 51 supports the entire second blade 50, preventing the second blade 50 from splashing and injuring people if it breaks, thus enhancing safety.

[0024] Specifically, the number of the first slots 20 and the number of the second slots 40 are both several, and the first slots 20 and the second slots 40 are staggered. The first blades 30 are installed in the first slots 20, and the second blades 50 are installed in the second slots 40. The staggered arrangement of the first blades 30 and the second blades 50 forms a staggered cutting pattern, which makes the cutting surface smoother, easier to cut, and reduces the load on the machine.

[0025] Specifically, the blade body 10 is made of aluminum, which reduces weight and load.

[0026] The utility model provides a door frame cutter, wherein a first blade is fixed in a first slot by a first pressure block, and a second blade is fixed in a second slot by a second pressure block. The first blade and the second blade are both easily replaceable, and the cutter body is reusable, thus saving costs. Moreover, when a blade breaks, the pressure block abuts against the entire blade, thereby preventing the blade from splashing and injuring people, thus providing high safety performance. In addition, one end of the first blade extends to the side of the cutter body, and one end of the second blade extends to the outer peripheral surface of the cutter body, thereby partially intersecting the working areas of the first blade and the second blade, ensuring that a complete product can be processed. At the same time, the two blades are used for staggered cutting, resulting in a smoother cut surface, easier cutting, and reduced machine load.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
