Claims

1. A tool for cutting circles and drilling holes in wooden boards, characterized in that, It includes two drill bits for cutting wooden boards, two mounting plates, an adjustment assembly, and a drive assembly, wherein, A first motor for driving the drill bit is fixed on the mounting plate, and a linkage assembly for connecting the output shaft of the first motor and the drill bit is provided. Both mounting plates are connected to an adjustment assembly, which drives the two mounting plates to move simultaneously towards each other or simultaneously away from each other to adjust the distance between the two drill bits. The drive assembly includes a support frame for mounting the adjustment assembly and a fixed plate for fixed mounting. A second motor is mounted on the fixed plate, and the output shaft of the second motor passes through the fixed plate and is connected to the support frame, for driving the support frame, the adjustment assembly, and the two drill bits to rotate synchronously around the output shaft of the second motor. The distance between the two drill bits and the output shaft of the second motor is the same.

2. The tool for cutting circles and drilling holes in wooden boards according to claim 1, characterized in that, The adjustment assembly includes a third motor, a lead screw, and two moving blocks. The third motor is mounted on one side of the support frame, and its output shaft passes through the support frame and is connected to the lead screw. The other end of the lead screw is rotatably connected to the support frame. The threads at both ends of the lead screw are in opposite directions, and the two moving blocks are located in two sections of the lead screw with opposite thread directions, with the moving blocks threaded around the outside of the lead screw.

3. The cutting tool for cutting circles and drilling holes in wooden boards according to claim 2, characterized in that, The receiving frame is fixed with a spacer block, and the spacer block has a through hole for the lead screw to pass through.

4. The cutting tool for cutting circles and drilling holes in wooden boards according to claim 3, characterized in that, The receiving frame is fixed with a guide rod, and the moving block is slidably sleeved on the outside of the guide rod.

5. The cutting tool for cutting circles and drilling holes in wooden boards according to claim 4, characterized in that, The moving block and the spacer block are provided with a first folded protective cover, and the moving block and the receiving frame are provided with a second folded protective cover. The first and second folded protective covers are used to cover the lead screw and the guide rod to prevent wood chips from sticking to the lead screw and the guide rod and affecting the smooth movement of the moving block on the lead screw.

6. The cutting tool for cutting circles and drilling holes in wooden boards according to claim 1, characterized in that, The linkage assembly includes a rotating shaft for connecting to the drill bit, a first gear sleeved on the output shaft of the first motor, and a second gear sleeved on the rotating shaft, wherein the first gear meshes with the second gear.
