[0002] Three-hole tool structure as follows Figure 4 As shown, the three-hole tool has cutting edges on both the left and right sides. It is mainly used for leather cutting. When processing the three-hole tool, it needs to be fixed and then the cutting edges on the four sides of the left and right sides need to be sharpened. Therefore, the left and right sides of the tool need to be exposed and the sharpening operation needs to be convenient. When the existing fixing fixture holds the tool, there is no limiting structure to further fix it. Therefore, during the sharpening process, the tool is prone to shaking or displacement, resulting in the tool being scrapped. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example 1:

[0019] A three-hole tool double-edged fixture, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a clamping handle 1 and a fixing cover 4. The clamping handle 1 is a columnar structure and includes a clamping part 11 and a mounting part 12. The clamping part 11 is used to cooperate with an external clamping device to fix the clamping handle 1, and the mounting part 12 is used to mount the cutting tool. The thickness of the mounting part 12 is less than the thickness of the clamping part 11. The mounting part 12 is provided with a mounting surface 121, which is a planar structure and is used to mount the cutting tool. An inclined transition surface 111 is provided on the clamping part 11 at one end near the mounting part 12. The bottom of the transition surface 111 is at the same height as the mounting surface 121. The transition surface 111 can make way for the fixing cover 4, which facilitates the installation of the fixing cover 4. A limiting component is provided on the mounting surface 121. Three clearance holes are arranged sequentially at the central axis of the tool, with equal spacing between them. The limiting component cooperates with the limiting holes at both ends of the tool to limit the tool. A threaded hole 122 is also provided on the mounting surface 121, located between the limiting components. A through hole 41 is provided on the fixing cover 4. The through hole 41 is coaxially arranged with the threaded hole 122 and the clearance hole at the middle position of the tool. The fixing cover 4 is connected to the mounting part 12 of the clamping handle 1 by bolts 5. The bolts 5 pass through the fixing cover 4 and the tool and are connected to the threaded hole 122, so that the fixing cover 4 cooperates with the clamping handle 1 to clamp and fix the tool.

[0020] The limiting assembly includes two limiting posts 123, which are respectively set on both sides of the threaded hole 122. The distance between the limiting post 123 and the threaded hole 122 is equal to the distance between adjacent clearance holes on the tool. The limiting post 123 is inserted into the clearance holes located at both ends of the tool. The height of the limiting post 123 is greater than the thickness of the tool. After the tool is placed on the mounting surface 121, the two limiting posts 123 are respectively inserted into the clearance holes near the left and right ends of the tool, and the tool is limited. At this time, the threaded hole 122 and the clearance hole in the middle of the tool are coaxially set. After the fixing cover 4 is covered, the tool can be tightened by connecting with bolts 5. Example 2:

[0021] This embodiment, based on the above embodiment, further defines the clamp 1 and the fixing cover 4, such as... Figure 1 , Figure 2 and Figure 3 As shown, a limiting block 3 is provided on the clamping handle 1 between the transition surface 111 of the clamping part 11 and the mounting surface 121 of the mounting part 12. The limiting block 3 protrudes from one end of the mounting surface 121 and abuts against the end of the tool. When the tool is mounted on the mounting surface 121, the end of the tool abuts against the side of the limiting block 3. A slot 42 is provided on the fixing cover 4 at one end near the transition surface 111 of the clamping handle 1. The slot 42 cooperates with the limiting block 3, and the limiting block 3 limits the fixing cover 4. When the fixing cover 4 is fixed to the mounting surface 121 by the bolt 5, the limiting block 3 is inserted into the slot 42 to further limit the fixing cover 4 and prevent the fixing cover 4 from rotating or shifting along the bolt 5.

[0022] In addition, the height of the limiting block 3 is greater than the thickness of the tool. Therefore, a clearance groove 43 is provided on the side of the fixed cover 4 located on the slot 42. The clearance groove 43 is spaced apart from the slot 42 and is used to make way for the limiting component. Abutment portions 44 are provided at both ends of the clearance groove 43 on the fixed cover 4. The abutment portions 44 abut against the tool surface. When the fixed cover 4 presses down on the tool, the abutment portions 44 abut against the tool surface. The clearance groove 43 can avoid the limiting post 123 that protrudes slightly from the tool surface, thereby pressing and fixing the tool.

[0023] The width of the cutting tool is greater than the width of the mounting surface 121, and both sides of the cutting tool can be exposed on the left and right sides of the mounting surface 121. The clamping part 11 of the fixture is fixed by an external clamping device, so that the left and right sides of the cutting tool can be sharpened. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again here.

[0024] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are 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. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
