Two slots 4 are opened on the side of the blade 3 close to the fixing block 2. Two inserting blocks 5 fixed to the fixing block 2 are respectively inserted into the two slots 4. Two sliding grooves 6 are respectively opened between the fixing block 2 and the two inserting blocks 5. Two limiting blocks 7 are respectively slidably connected in the two sliding grooves 6, and one ends of the two limiting blocks 7 are respectively inserted and matched with the two slots 4;

[0039] a plurality of transmission components. The plurality of transmission components are respectively located in the plurality of fixing blocks 2 and are used to drive the corresponding two limiting blocks 7 respectively.

[0040] Embodiment 2:

[0041] This embodiment provides a disc cutter for woodworking. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The transmission component includes:

[0042] The second rotating groove 12 is formed in the fixed block 2 and communicates with the two sliding grooves 6. A turntable 13 fixed to the other end of the transmission rod 9 is rotatably connected in the second rotating groove 12. Two arc-shaped grooves 14 are formed in the turntable 13. Two transmission blocks 15 are respectively slidably connected in the two arc-shaped grooves 14, and one ends of the two transmission blocks 15 respectively extend into the two sliding grooves 6 and are respectively fixed to the two limiting blocks 7.

[0043] The third rotating groove 16 is formed in the inner wall of the second rotating groove 12. A rotating rod 17 fixed to the turntable 13 is rotatably connected in the third rotating groove 16. A torsion spring 18 is arranged on the rotating rod 17. One end of the torsion spring 18 is fixed to the circumferential side of the rotating rod 17, and the other end of the torsion spring 18 is fixed to the inner wall of the third rotating groove 16.

[0044] Among them, when the blade 3 wears out during long-term use and needs to be replaced, the user inserts the insertion rod 11 into the insertion hole 10 by hand. Subsequently, the user rotates the insertion rod 11 by hand, so that the insertion rod 11 drives the transmission rod 9 to rotate in the first rotation groove 8 through the insertion hole 10, causing the transmission rod 9 to drive the turntable 13 to rotate in the second rotation groove 12, and the turntable 13 drives the rotating rod 17 to rotate in the third rotation groove 16. When the rotating rod 17 rotates, the rotating rod 17 will twist the torsion spring 18, causing the torsion spring 18 to undergo elastic deformation. At the same time, when the turntable 13 rotates, the turntable 13 squeezes the two transmission blocks 15 through the two arc-shaped grooves 14 respectively, causing the two transmission blocks 15 to drive the two limit blocks 7 to move in the two sliding grooves 6 respectively, so that one ends of the two limit blocks 7 move from the two insertion slots 4 into the two sliding grooves 6 respectively. At this time, the fixation of the blade 3 is released. Subsequently, the user pulls the blade 3 by hand, causing the blade 3 to move along the transmission rod 9 in a direction away from the fixed block 2, so that the two insertion blocks 5 move out of the two insertion slots 4 into the outside world respectively. When the blade 3 moves to a suitable position, the user pulls out the insertion rod 11 from the insertion hole 10. When the insertion rod 11 is pulled out from the insertion hole 10, the rotating rod 17 will rotate in the reverse direction under the action of the rebound force of the torsion spring 18, and the rotating rod 17 will drive the turntable 13 to rotate in the reverse direction in the second rotation groove 12, causing the turntable 13 to squeeze the two transmission blocks 15 through the two arc-shaped grooves 14 respectively, causing the two transmission blocks 15 to drive the two limit blocks 7 to move in the reverse direction in the two sliding grooves 6 respectively, so that one ends of the two limit blocks 7 move out of the two sliding grooves 6 into the outside world respectively. Then the user removes the blade 3 from the periphery of the transmission rod 9 by hand for replacement. After replacement, the user inserts the blade 3 back onto the periphery of the transmission rod 9 by hand, and inserts the two insertion blocks 5 into the two insertion slots 4 respectively. When the two insertion blocks 5 are inserted into the two insertion slots 4 respectively, the inner walls of the two insertion slots 4 will squeeze one ends of the two limit blocks 7 respectively, causing one ends of the two limit blocks 7 to enter the two sliding grooves 6 from the outside world respectively, and the two limit blocks 7 will squeeze the two arc-shaped grooves 14 through the two transmission blocks 15 respectively, causing the turntable 13 to rotate in the second rotation groove 12, and the turntable 13 drives the rotating rod 17 to rotate in the third rotation groove 16. When the rotating rod 17 rotates, the rotating rod 17 will twist the torsion spring 18, causing the torsion spring 18 to undergo elastic deformation. When the two insertion blocks 5 are completely inserted into the two insertion slots 4, the rotating rod 17 will rotate in the reverse direction under the action of the rebound force of the torsion spring 18, and the rotating rod 17 will drive the turntable 13 to rotate in the reverse direction in the second rotation groove 12, causing the turntable 13 to squeeze the two transmission blocks 15 through the two arc-shaped grooves 14 respectively, causing the two transmission blocks 15 to drive the two limit blocks 7 to move in the reverse direction in the two sliding grooves 6 respectively, so that one ends of the two limit blocks 7 are inserted into the two insertion slots 4 along the two sliding grooves 6 respectively, fixing the blade 3 on the fixed block 2, ensuring that the user can quickly replace the blade 3.

[0056] Among them, it is ensured that one end of the transmission rod 9 can rotate normally within the blade 3.

[0057] It should be noted that: multiple jacks 10 can share one insertion rod 11, which reduces the production cost.

[0058] When the blade 3 needs to be replaced due to wear during long-term use, the user inserts the insertion rod 11 into the insertion hole 10 by hand. Subsequently, the user rotates the insertion rod 11 by hand, so that the insertion rod 11 drives the transmission rod 9 to rotate in the first rotation groove 8 through the insertion hole 10, causing the transmission rod 9 to drive the turntable 13 to rotate in the second rotation groove 12, and the turntable 13 drives the rotating rod 17 to rotate in the third rotation groove 16. When the rotating rod 17 rotates, the rotating rod 17 will twist the torsion spring 18, causing the torsion spring 18 to undergo elastic deformation. At the same time, when the turntable 13 rotates, the turntable 13 squeezes the two transmission blocks 15 through the two arc-shaped grooves 14 respectively, causing the two transmission blocks 15 to drive the two limit blocks 7 to move in the two sliding grooves 6 respectively, so that one ends of the two limit blocks 7 move from the two insertion slots 4 into the two sliding grooves 6 respectively. At this time, the fixation of the blade 3 is released. Subsequently, the user pulls the blade 3 by hand, causing the blade 3 to move along the transmission rod 9 in a direction away from the fixed block 2, so that the two insertion blocks 5 move out of the two insertion slots 4 into the outside world respectively. When the blade 3 moves to a suitable position, the user pulls out the insertion rod 11 from the insertion hole 10. When the insertion rod 11 is pulled out from the insertion hole 10, the rotating rod 17 will rotate in the reverse direction under the action of the rebounding force of the torsion spring 18, and the rotating rod 17 will drive the turntable 13 to rotate in the reverse direction in the second rotation groove 12, causing the turntable 13 to squeeze the two transmission blocks 15 through the two arc-shaped grooves 14 respectively, so that the two transmission blocks 15 drive the two limit blocks 7 to move in the reverse direction in the two sliding grooves 6 respectively, so that one ends of the two limit blocks 7 move from the two sliding grooves 6 into the outside world respectively. Then the user removes the blade 3 from the periphery of the transmission rod 9 by hand for replacement. After replacement, the user inserts the blade 3 back onto the periphery of the transmission rod 9 by hand, and inserts the two insertion blocks 5 into the two insertion slots 4 respectively. When the two insertion blocks 5 are inserted into the two insertion slots 4 respectively, the inner walls of the two insertion slots 4 will squeeze one ends of the two limit blocks 7 respectively, causing one ends of the two limit blocks 7 to enter the two sliding grooves 6 from the outside world respectively, and the two limit blocks 7 will squeeze the two arc-shaped grooves 14 through the two transmission blocks 15 respectively, causing the turntable 13 to rotate in the second rotation groove 12, and the turntable 13 drives the rotating rod 17 to rotate in the third rotation groove 16. When the rotating rod 17 rotates, the rotating rod 17 will twist the torsion spring 18, causing the torsion spring 18 to undergo elastic deformation. When the two insertion blocks 5 are completely inserted into the two insertion slots 4, the rotating rod 17 will rotate in the reverse direction under the action of the rebounding force of the torsion spring 18, and the rotating rod 17 will drive the turntable 13 to rotate in the reverse direction in the second rotation groove 12, causing the turntable 13 to squeeze the two transmission blocks 15 through the two arc-shaped grooves 14 respectively, so that the two transmission blocks 15 drive the two limit blocks 7 to move in the reverse direction in the two sliding grooves 6 respectively, so that one ends of the two limit blocks 7 are inserted into the two insertion slots 4 along the two sliding grooves 6 respectively, fixing the blade 3 on the fixed block 2, ensuring that the user can quickly replace the blade 3.
