[0023] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1-4 A cutting mechanism of an overlocking machine comprises a workbench 1, a support frame 2 is fixedly connected to the lower surface of the workbench 1 symmetrically along the center, a stable base 3 is fixedly connected to the bottom end of the support frame 2, an overlocking machine body 4 is detachably mounted in the middle of the upper surface of the workbench 1, a moving component 5 is fixedly connected to the top of the side wall of the overlocking machine body 4, a cutting component 6 is detachably mounted on the bottom end of the moving component 5, and a protective shell 7 is clamped at the bottom end of the cutting component 6;

[0026] The protective shell 7 is made of a plastic component, and the corners of the protective shell 7 are rounded. The moving component 5 includes a limit block 51 and a limit hole 52. The middle of the upper surface of the limit block 51 is penetrated by a limit hole 52. The side wall of the limit block 51 is connected to the top of the side wall of the overlock machine body 4. A hydraulic telescopic rod 53 is detachably installed on one side of the inner part of the limit hole 52. One end of the hydraulic telescopic rod 53 is fixedly connected to a connecting slider 54. The bottom end of the side wall of the connecting slider 54 is penetrated by a first connecting hole 55. The surface of the connecting slider 54 is adapted to the inner part of the limit hole 52. The cutting component 6 includes a mounting block 61 and a second connecting hole 62. The middle of the upper surface of the mounting block 61 is opened. There is a second connecting through hole 62, the interior of the second connecting through hole 62 is adapted to the bottom end of the connecting slider 54, and a third connecting through hole 63 is opened through the middle of the side wall of the mounting block 61, a fastening ring 64 is bonded to one side of the inside of the third connecting through hole 63, and a quick plug-in pin 65 is clamped inside the third connecting through hole 63. The fastening ring 64 is made of a rubber component, and one end of the quick plug-in pin 65 is connected to the inside of the fastening ring 64 through the third connecting through hole 63 and the first connecting through hole 55. A hydraulic lifting rod 66 is detachably installed at the bottom end of the second connecting through hole 62, and a blade 67 is fixedly connected to the bottom end of the hydraulic lifting rod 66, and the surface of the blade 67 is adapted to the inside of the protective shell 7.

[0027] Benefits: By setting the material of the fastening ring 64 to a rubber component, it is helpful to increase the friction between the fastening ring 64 and the quick plug-in pin 65, thereby ensuring the stability of the cutting assembly 6 when connected.

[0028] The working process of the utility model is as follows:

[0029] When the cutting mechanism is in use, in order to eliminate safety hazards, a protective shell 7 is provided. When the staff is about to come into contact with the blade 67, the protective shell 7 provided on the surface of the blade 67 will work, and then the protective shell 7 will come into contact with the staff instead of the blade 67. Because the edges and corners of the protective shell 7 are rounded and the material is a plastic component, it will not cause damage to the staff when it comes into contact with the staff. Because the protective shell 7 is clamped on the surface of the blade 67 and can be directly pulled out, it will not affect the normal operation of the cutting component 6, thereby enhancing the practicability of the device.

[0030] In the above scheme, when the cutting mechanism is in use, in order to facilitate the disassembly of the cutting assembly 6, a connecting slider 54, a first connecting through hole 55, a second connecting through hole 62, a third connecting through hole 63, a fastening ring 64 and a quick-plug pin 65 are provided. When the cutting assembly 6 is to be disassembled, it is only necessary to pull out the quick-plug pin 65 from the inside of the fastening ring 64, the third connecting through hole 63 and the first connecting through hole 55 respectively, and the cutting assembly 6 can be disassembled, because the quick-plug pin 65 is respectively clamped in the inside of the fastening ring 64, the third connecting through hole 63 and the first connecting through hole 55, and the connecting slider 54 is clamped in the inside of the second connecting through hole 62, so they can all be directly pulled out. Compared with the bolt connection method to connect the cutting assembly 6 with the moving assembly 5, this connection method saves time and thus improves the working efficiency of the device.
