[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] like Figure 1-4 As shown, a combined trimming knife includes a handle 1, a support rod 2, a sliding sleeve 5, a knife holder 7, and a trimming blade 9. One end of the handle 1 is fixedly connected to the support rod 2 with the same axis. Multiple detachably connected sliding sleeves 5 are sleeved on the support rod 2, and a limiting structure is provided to limit the movement of the sliding sleeves 5. Multiple detachably connected knife holders 7 are evenly arranged along the circumference of the sliding sleeves 5, and trimming blades 9 are fixedly connected to the knife holders 7.

[0023] Specifically, the tool holder 1 is used to connect with equipment such as milling machines, and the support rod 2 is used to support the sliding sleeve 5. The sliding sleeve 5, which is sleeved on the support rod 2, can be slid off for replacement or maintenance. Through the limiting structure, the sliding sleeve 5 can be prevented from rotating on the support rod 2 after installation, so as to ensure that when the tool holder 1 is driven to rotate, the sliding sleeve 5 rotates with the support rod 2 to trim the edge of the wood. At the same time, different shapes of trimming blades 9 can be installed on different sliding sleeves 5 to meet various complex and varied trimming needs.

[0024] Furthermore, the limiting structure consists of multiple limiting grooves 3 evenly arranged around the support rod 2, and the limiting grooves 3 extend along the axial direction of the support rod 2. The inner wall of the sliding sleeve 5 is provided with limiting strips 15 that are adapted to the limiting grooves 3.

[0025] Specifically, by fitting the limiting strip 15 with the limiting groove 3, the limiting strip 15 can slide along the limiting groove 3 when installing the sliding sleeve 5, so as to smoothly install the sliding sleeve 5, while preventing the sliding sleeve 5 from rotating on the support rod 2.

[0026] Furthermore, a plug 10 is provided at the end of the support rod 2 away from the handle 1. Multiple plug bolts 11 are provided around the plug 10 for fastening the plug 10. The plug 10 is provided with a rod groove 14 that is adapted to the end of the support rod 2.

[0027] Specifically, after the plug 10 is fixedly installed at the end of the support rod 2, it can restrict the sliding sleeve 5 and prevent the sliding sleeve 5 from falling off the support rod 2. At the same time, one end of the support rod 2 is inserted into the rod groove 14 to prevent the plug 10 from rotating.

[0028] Furthermore, the bottom of the plug 10 is provided with a milling cutter 12, which can cut the wood by rotating the 12 and then perform operations such as grooving.

[0029] Furthermore, a limiting plate 4 is provided at the junction between the tool holder 1 and the support rod 2, and a separating ring 6 is provided between two adjacent sliding sleeves 5, and the separating ring 6 is detachably connected to the tool holder 1.

[0030] Specifically, to further prevent the sliding sleeve 5 from slipping off to the outer wall of the tool holder 1, the separating ring 6 between adjacent sliding sleeves 5 can increase the distance between the sliding sleeves 5 and avoid mutual interference during trimming.

[0031] Furthermore, the sliding sleeve 5 has a tool holder groove 13 that can accommodate the tool holder 7. The tool holder 7 and the sliding sleeve 5 are fastened together by the tool holder bolt 8. The tool holder 7 is installed inside the tool holder groove 13 and fixed by the tool holder bolt 8 that is screwed to the sliding sleeve 5, which facilitates the installation or removal of the tool holder 7.

[0032] In the above structure, the trimming cutter is driven to rotate during use. Different blades contact the material to trim different shapes of edges. At the same time, the milling cutter 12 can be used to make grooves. When the cutter needs to be replaced, the cutter holder bolt 8 can be turned to tighten or loosen the cutter holder 7, thereby installing or removing the cutter holder 7 to replace the trimming cutter 9. When the plug 10 or the sliding sleeve 5 needs to be replaced, the plug bolt 11 can be turned to tighten or loosen the plug 10, which is convenient for installing or removing the plug 10. The plug 10 can be removed from one end of the support rod 2, and the sliding sleeve 5 can be fitted onto the side of the support rod 2 or removed from the support rod 2. After the plug 10 is installed and fixed, the sliding sleeve 5 can be limited and prevented from falling off.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
