[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, a replaceable wood trimming knife, comprising: a blade 1, a side block 2, a locking screw 3, a groove 4, a pressure block 5, a bottom plate 6, a fixing screw 7, a butterfly nut 8, a moving wheel 9, a side auxiliary cylinder 10, a screw hole 11 and a rubber strip 12, and also comprising: the blade 1 is made of tungsten steel, has high hardness and strength, is convenient for cutting hardwood, ensures the working effect of the blade 1, and has cutting edges on both sides of the blade 1, which is convenient for the user to cut both sides synchronously when moving the blade 1. At the same time, considering the holding effect of the blade 1 and the moving effect on one side of the wood, one end of the blade 1 is penetrated inside the side block 2 to facilitate the installation of one side of the blade 1. Specifically, a locking screw 3 is threadedly connected above the side block 2 to lock and fix the blade 1, and considering the installation stability of the blade 1 inside the side block 2, the side A through hole for accommodating the insertion of the blade 1 is provided inside the block 2, and the blade 1 is inserted inside the through hole of the side block 2, and a groove 4 is provided on the surface of one end of the insertion. A rubber pad is provided on the surface of the groove 4, and the rubber pad is provided inside the side block 2, so as to achieve the stability of the blade 1 inside the through hole, and facilitate the stable connection of the rubber pad with the side block 2 inside the through hole. At the same time, a screw hole 11 is provided inside the groove 4 corresponding to the locking screw 3, and a screw groove is provided above the through hole corresponding to the screw hole 11, so as to facilitate the locking screw 3 to synchronously fix the blade 1 inside the side block 2 through the screw hole 11 and the screw groove, and considering the movement effect of the side block 2 on the side edge of the wood, a plurality of sets of side auxiliary cylinders 10 are rotatably provided on the inner side of the side block 2, so as to facilitate the precise movement of the side block 2 through the side auxiliary cylinders 10, and avoid the problem of uneven trimming;

[0025] In order to achieve precise movement and balance of the blade 1 at the corner of the wood, the side of the blade 1 away from the side block 2 is installed at the bottom end of the pressing block 5, and in order to achieve stability, the bottom end of the blade 1 is fixedly installed at the bottom end of the pressing block 5 through the bottom plate 6. Specifically, a wedge-shaped groove for accommodating the bottom plate 6 for embedded installation is opened at the bottom end of one side of the blade 1, and a plurality of groups of rubber strips 12 are fixedly connected to the surface of the wedge-shaped groove to ensure the friction effect between the wedge-shaped groove and the surface of the bottom plate 6, thereby achieving the stability of the bottom plate 6 at the bottom end of the blade 1. At the same time, a fixing screw 7 is connected to the surface of the bottom plate 6, and the fixing screw 7 is vertically arranged with the bottom plate 6, and the fixing screw 7 is fixedly installed at the bottom end of the blade 1. 1 is penetrated on one side, so that the fixing screw 7 drives the bottom plate 6 to fix the blade 1, and the outer wall of the fixing screw 7 is locked and fixed by the butterfly nut 8, and the butterfly nut 8 is installed on the surface of the pressing block 5, so that the bottom plate 6 is locked at the bottom end of the blade 1, which is convenient for the blade 1 to be fixed and installed at the bottom end of the pressing block 5. At the same time, multiple sets of moving wheels 9 are rotatably arranged at the bottom end of the pressing block 5. Through the arrangement of multiple sets of moving wheels 9, the blade 1 can be synchronously rotated when moving on the wood surface, and the moving wheel 9 and the side auxiliary cylinder 10 are arranged to rotate vertically, which is convenient for trimming the vertical side of the wood, thereby ensuring the working quality of the trimming knife.

[0026] Working principle: When in use, the blade 1 is inserted into the inside of the side block 2 through the locking screw 3, so as to fix one side of the blade 1. At the same time, the other side of the blade 1 is installed at the bottom end of the pressure block 5 through the bottom plate 6, and the fixing screw 7 is fixed by the butterfly nut 8, so that the bottom plate 6 presses the blade 1 at the bottom, ensuring the convenience of installation at both ends of the blade 1, facilitating the maintenance and replacement of the blade 1, and reducing the maintenance cost. In addition, by arranging blades on both sides of the blade 1, when the trimming knife moves on the corners of the wood through the side block 2 and the pressure block 5, the pressure block 5 moves on the surface of the wood through the moving wheel 9. At the same time, the side block 2 moves synchronously on the side of the wood through the side auxiliary cylinder 10, so as to facilitate the precise trimming of the blade 1 and realize the trimming flatness of the wood.
