[0007] To achieve the above object, the utility model provides the following technical solutions: A quick-release circular knife for a circular cutting machine, including a knife seat, a blade, a connecting piece and a locking piece. The connecting piece includes an elastic piece, a sliding plate, an inclined plate and a fixing tube. The fixing tube is arranged at the center below the knife seat. Several groups of sliding grooves are arranged below the knife seat, and the sliding grooves are arranged on the periphery of the fixing tube. The sliding plate is in an inverted L shape. An inclined plate extending into the fixing tube is arranged on the side wall of the sliding plate near the fixing tube. A clamping groove is also arranged at the end of the sliding plate away from the fixing tube. A through hole is arranged at the center of the blade, and the center of the blade is adapted to the clamping groove. The locking piece includes a bolt and a top block. A thread adapted to the bolt is arranged at the end of the fixing tube away from the knife seat, and a top block adapted to the inclined plate is also arranged on the bolt.

[0008] To ensure the stability of the sliding plate movement, the utility model is improved in that the elastic piece includes a spring and a telescopic rod. The spring is sleeved on the telescopic rod, and the elastic piece is arranged at the end away from the fixing tube.

[0009] To ensure the stability of the blade assembly, the utility model is improved in that a guiding groove adapted to the sliding plate is also arranged on the through hole.

[0010] To facilitate driving the bolt, the utility model is improved in that a handle is arranged below the bolt.

[0011] Preferably, the handle is provided with friction lines.

[0012] (3) Beneficial Effects

[0013] Compared with the prior art, the present utility model provides a quick-release circular knife for a circular cutting machine, which has the following beneficial effects:

[0014] For the quick-release circular knife of the circular cutting machine, initially, the bolt with the top block is not inserted into the fixed tube, and the elastic member is in an extended state. At this time, the card slot of the sliding plate does not engage with the blade, which facilitates the disassembly of the blade. When the upper part of the blade contacts the tool holder, it is connected to the fixed tube through the bolt, the top block abuts against the inclined plate of the sliding plate, and the card slot of the sliding plate catches the blade to complete the assembly.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, A quick-release circular blade for a circular cutting machine, comprising a tool holder 1, a blade 2, a connecting member and a locking member. The connecting member includes an elastic member, a sliding plate 3, an inclined plate 4 and a fixed tube 5. The fixed tube 5 is provided at the center below the tool holder 1. A plurality of groups of sliding grooves are provided below the tool holder 1, and the sliding grooves are arranged on the periphery of the fixed tube 5. The sliding plate 3 is in an inverted L shape. An inclined plate 4 extending into the fixed tube 5 is provided on the side wall of the sliding plate 3 near one end of the fixed tube 5. A clamping groove is further provided at the end of the sliding plate 3 away from the fixed tube 5. A through hole is provided at the center of the blade 2, and the center of the blade 2 is adapted to the clamping groove. The locking member includes a bolt 6 and a top block 7. A thread adapted to the bolt 6 is provided at one end of the fixed tube 5 away from the tool holder 1, and a top block 7 adapted to the inclined plate 4 is further provided on the bolt 6.

[0022] During actual use, initially, the elastic member is in an extended state. The sliding plate 3 drives the inclined plate 4 to insert into the fixed tube 5. At this time, the outer diameter of the side plate of the sliding plate 3 is adapted to the inner diameter of the through hole of the blade 2. The blade 2 passes through the sliding plate 3 and fits with the tool holder 1. By driving the top block 7 with the bolt 6, the top block 7 abuts against the inclined plate 4, the elastic member contracts, and the clamping groove of the sliding plate 3 clamps the blade 2 to complete the assembly of the blade 2.

[0023] In this embodiment, the elastic member includes a spring 8 and a telescopic rod 9. The spring 8 is sleeved on the telescopic rod 9. The elastic member is arranged at one end away from the fixed tube 5. The spring 8 is sleeved on the telescopic rod 9 to ensure the stability of the operation of the sliding plate 3.

[0024] In order to prevent the blade 2 from slipping as the tool holder 1 moves, in this embodiment, a guiding groove adapted to the sliding plate 3 is further provided on the through hole to ensure the stability of the assembly of the blade 2.

[0025] In order to prevent the driving bolt 6 from slipping, in this embodiment, a handle 10 is provided below the bolt 6, and a friction pattern 11 is provided on the handle 10.
