[0019] As attached Figure 1 -Attached Figure 3A quick release mechanism shown in the figure comprises a housing 1, a cutter head 2, a disassembly assembly 3, a fixed block 4, a limiting block 5, a push plate 6, a top block 61, a slide groove 62, a spring movable groove 7, a return spring 8, a cutter head groove 9, a hinge seat 10, a limiting column 11, and a bolt hole 12. The cutter head 2 is arranged inside the housing 1, and the disassembly assembly 3 is arranged at both ends of the cutter head 2. The disassembly assembly 3 comprises a fixed block 4, a limiting block 5 and a push plate 6. The push plate 6 is provided with a slide groove 62, and a top block 61 is fixedly installed on the lower surface of the push plate 6;
[0020] A cutter head groove 9 is provided on the upper surface of the fixing block 4, a hinge seat 10 is provided on one side of the cutter head groove 9, a bolt hole 12 is provided on one side of the hinge seat 10, a limiting column 11 and a spring movable groove 7 are provided on the other side of the cutter head groove 9, and a return spring 8 is installed in the spring movable groove 7.
[0021] Furthermore, the hinged seat 10 on the fixed block 4 is movably connected to the limit block 5 via a pin shaft, and the cutter head groove 9 and the limit block 5 form a group of circular slots for fixing the cutter head 2, so that the limit block 5 can rotate on the fixed block 4, thereby fixing the cutter head 2.
[0022] Furthermore, a groove is provided at one end of the push plate 6, and a protrusion is provided at one end of the limit block 5, and the two are engaged with each other, and the limit block 5 is engaged and fixed by the push plate 6, so that the groove on the push plate 6 and the protrusion on the limit block 5 are engaged and fixed, thereby completing the docking between the two.
[0023] Furthermore, the limiting column 11 passes through the slide groove 62 on the push plate 6 , wherein a group of limiting bolts are installed at the top end of the limiting column 11 for limiting the push plate 6 , so that the limiting column 11 passes through the slide groove 62 , thereby limiting the push plate 6 .
[0024] Furthermore, a fastening bolt is embedded in the bolt hole 12 on the fixing block 4 , so as to fix the fixing block 4 to the inner side of the housing 1 , so that the fixing block 4 can be installed and fixed by passing the fastening bolt through the bolt hole 12 .
