[0011] In the figure, 1, milling cutter spindle; 2, milling blade; 3, mounting portion; 4, fixing ring; 5, positioning assembly; 6, connecting rod; 7, abutment portion; 8, return spring; 9, mounting groove; 10, positioning rod. DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the milling cutter blade comprises a milling cutter spindle 1 and a milling cutter blade 2. The front end portion of the milling cutter spindle 1 is provided with a mounting portion 3 for installing the milling cutter blade 2. A fixing ring 4 is fixedly mounted on the milling cutter spindle 1. The fixing ring 4 is provided with a plurality of positioning components 5 for fixing the blade. The positioning component 5 comprises a connecting rod 6, a supporting portion 7 and a reset spring 8. The fixing ring 4 is provided with a mounting groove 9 for installing the positioning component 5. The reset spring 8 is arranged in the mounting groove 9, and one end of the reset spring 8 is abutted against the bottom wall of the mounting groove 9, and the other end of the reset spring 8 is abutted against the connecting rod 6. The connecting rod 6 extends out of the lower end of the fixing ring 4 and is connected to the supporting portion 7. The supporting portion 7 abuts against the milling cutter blade 2 to fix the milling cutter blade 2. The supporting portion 7 slides up and down in the mounting groove 9 under the action of the reset spring 8 to fix the milling cutter blade 2.

[0014] To elaborate further, there are a plurality of milling blades 2, and the mounting portions 3 are respectively provided with slots for mounting the milling blades 2, and a positioning component 5 is provided at the mounting position of each of the milling blades 2 for positioning therewith.

[0015] To elaborate further, when the blade needs to be disassembled, it is only necessary to apply pressure to the connecting rod 6 of the positioning assembly 5, the reset spring 8 is in a compressed state, the connecting rod 6 moves downward, and the abutment portion 7 no longer abuts against the blade, so that the blade can be removed from the mounting portion 3. When the blade needs to be installed, the pressure on the connecting rod 6 of the positioning assembly 5 is released, the reset spring 8 rebounds, the connecting rod 6 moves upward, and the abutment portion 7 abuts against the blade, thereby fixing the blade on the mounting portion 3.

[0016] In further detail, the connecting rod 6 and the abutting portion 7 are integrally formed, and a positioning rod 10 for positioning the blade is provided on the mounting portion 3 at a position relative to each blade, and the blade is provided with an opening that matches the positioning rod 10. During the installation process, the positioning rod 10 matches the opening on the blade, thereby strengthening the fixation of the blade, but does not affect the removal of the blade.

[0017] To be more specific, the fixing ring 4 is fixedly mounted on the fixing ring 4 of the milling cutter spindle 1 by a plurality of fixing bolts.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although the terms such as milling cutter spindle 1, milling blade 2, mounting portion 3, fixing ring 4, positioning assembly 5, connecting rod 6, abutment portion 7, return spring 8, mounting groove 9, positioning rod 10 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
