Without additional statements, the above terms have no special meaning, so it should not be construed as a limitation on the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0022] A cutting tool, comprising a tool handle 1, a tool head 2 and a cutting blade 3. The tool handle 1 includes a tool handle main body 101, a tool head fixing hole 102 and a limiting block hole 103. A first screw 5 is provided at the top of the tool handle 1. One end of the tool handle 1 is fixedly connected to a rotating shaft 4. The outer periphery of the rotating shaft 4 is rotatably connected to the tool head 2. The tool head 2 includes a tool head main body 201, a limiting block 202, a tool head fixing groove 203, a cutting blade fixing hole 204 and a rotating shaft hole 205. A third screw 7 is rotatably connected to the side of the tool handle 1 away from the tool head 2. An adjusting block 8 is provided at the bottom of the tool handle 1. The adjusting block 8 includes an adjusting block main body 801 and an adjusting nut 802. The cutting blade 3 is provided at the top of the tool head 2. A second screw 6 is rotatably connected to the top of the cutting blade 3, and the second screw 6 is threadedly connected to the tool head 2.

[0023] The tool head fixing hole 102 and the limiting block hole 103 are provided at the top of the tool handle main body 101 to facilitate the fixing of the tool head 2; the limiting block 202 is fixedly connected to the top of the tool head main body 201 to facilitate the positioning and installation of the cutting blade 3. The tool head fixing groove 203, the cutting blade fixing hole 204 and the rotating shaft hole 205 are provided at the top of the tool head main body 201. The tool head fixing groove 203 is semi-circular, and the cutting blade fixing hole 204 and the rotating shaft hole 205 are through holes to ensure the accurate installation of all moving parts. The diameter of the first screw 5 is the same as the width of the tool head fixing groove 203 so that the tool head 2 will not move after installation. There are 2 limiting blocks 202, and the distance between the inner sides of the 2 limiting blocks 202 is the same as the width of the cutting blade 3 to ensure the accuracy of the installation of the cutting blade 3. The adjusting nut 802 is fixedly connected to the top of the adjusting block main body 801, and the adjusting nut 802 is threadedly connected to the third screw 7 to facilitate the adjustment of the height of the entire tool.

[0024] Workflow: Place the blade 3 on the top of the cutter head body 201, with the blade 3 positioned between two limit blocks 202. Pass the second screw 6 through the blade fixing hole 204 to fix the blade 3 to the cutter head 2. Rotate the cutter head 2 so that the rotating shaft hole 205 rotates around the rotating shaft 4. After adjusting the cutter head 2 to the appropriate angle, pass the first screw 5 through the cutter head fixing hole 102, and the bottom of the first screw 5 contacts the bottom of the cutter head fixing groove 203 to fix the cutter head 2 to the handle body 101. Pass a tool through the limit block hole 103 and rotate the third screw 7 to push the adjusting nut 802 to move up and down, thereby driving the adjusting block body 801 to move up and down. The two groups of third screws 7 can ensure that the adjusting block 8 can only move up and down, thus changing the height of the entire tool. Finally, install the handle 1 onto the tool holder to use it.
