DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings to make the technical solution of the present application easier to understand and grasp.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The present embodiment is an anti-mis-touch overlock sewing machine, comprising a base 1, a body 2 is mounted on the base 1, a head 3 is mounted on one end of the body 2, a needle 31 and a presser foot 32 are mounted on the bottom of the head 3, and a control panel 4 is arranged on the outer surface of the body 2. A protective cover 5 is arranged on the body 2, and a bending portion 7 is formed by bending at the top of the protective cover 5, and the bending portion 7 comprises a first bending plate 71 and a second bending plate 72, and the two ends of the first bending plate 71 are respectively connected to the second bending plate 72 and the protective cover 5, and a first convex strip 721 is fixedly connected to a surface of the second bending plate 72 close to the protective cover 5, and a first groove 722 is provided on the second bending plate 72, and the first groove 722 is located above the first boss. The protective cover 5, the first bending plate 71, the second bending plate 72, and the first convex strip 721 are all plastic parts and have deformability.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The machine body 2 is also fixed with a mounting seat 6, which is located above the control panel 4. A slot 61 is provided on the top surface of the mounting seat 6 to engage with the second bending plate 72. The slot 61 is an oblique slot, and the distance between the slot 61 and the machine body 2 gradually increases from the top end of the slot 61 to the bottom end of the slot 61. When the overlock sewing machine is working, the bending portion 7 is inserted into the slot 61, and the second convex strip 62 is inserted into the first groove 722 and abuts against the first convex strip 721. At this time, the second convex strip 62 can limit the movement of the first convex strip 721 to achieve the effect of limiting the bending portion 7 from being separated from the slot 61, so that when the operator of the overlock sewing machine accidentally touches the protective cover 5, it is not easy to push the second bending plate 72 out of the slot 61.

[0033] Reference Figure 1 , Figure 3 and Figure 4 , a mounting groove 51 is provided on the protective cover 5, the mounting groove 51 penetrates the protective cover 5, and a magnifying glass 52 is fixedly connected in the mounting groove 51. A slide groove 33 is provided on the machine body 2 along the Z-axis direction, the slide groove 33 is located above the presser foot 32, the slide groove 33 is a dovetail groove, and the diameter of the slide groove 33 gradually decreases from the bottom of the slide groove 33 to the notch of the slide groove 33. A slider 8 is slidably connected in the slide groove 33 along the Z-axis direction, a first threaded hole 81 is provided on the slider 8 along the Y-axis direction, a bolt 9 is threadedly connected to the first threaded hole 81, and a plurality of second threaded holes 34 for connecting the bolts 9 are provided in the slide groove 33, and the plurality of second threaded holes 34 are equidistantly arranged along the length direction of the slide groove 33.

[0034] Reference Figure 1 , Figure 2 and Figure 5 A connecting rod 82 is fixed on the slider 8, and the length of the connecting rod 82 can be extended. A fixed shaft 83 is fixedly connected to the end of the connecting rod 82 away from the slider 8, and the axis of the fixed shaft 83 is parallel to the X-axis. The bending portion 7 is rotatably matched with the fixed shaft 83. The fixed shaft 83 is provided with a thread, and a nut 84 is threadedly connected to the fixed shaft 83. The nut 84 is used to press the bending portion 7 against the connecting rod 82 and limit the rotation of the bending portion 7. When the bending portion 7 is rotatably connected to the fixed shaft 83, the magnifying glass 52 is used to magnify the sewing part of the cloth below the needle 31.

[0035] Reference Figure 1 , Figure 2 and Figure 5 When the operator needs to use the magnifying glass 52 to observe the sewing quality of the fabric, the operator first rotates the bending portion 7 to connect it to the fixed shaft 83, and then can slide the slider 8 to a suitable height according to his / her visual field so that the first threaded hole 81 is connected to the corresponding second threaded hole 34, and then use the bolt 9 to connect to the first threaded hole 81 and the second threaded hole 34 respectively, so that the bolt 9 fixes the slider 8, and then rotates the bending portion 7 so that the bottom end of the needle 31, the magnifying glass 52 and the operator's eyes are in a straight line, so that the operator can more easily and clearly observe the sewing of the fabric. Then, by rotating the nut 84, the nut 84 is close to the bending portion 7 and finally the bending portion 7 is pressed against the connecting rod 82, thereby preventing the bending portion 7 from rotating during the operation of the overlock sewing machine and preventing the bending portion 7 from falling off the fixed shaft 83.

[0036] Reference Figure 1 , Figure 3 and Figure 4At the same time, a third threaded hole 711 for connection with a bolt 9 is opened on the first bending plate 71, and a fourth threaded hole 63 for connection with the bolt 9 is opened on the mounting seat 6. When the overlock machine is not used for a long time, the bending portion 7 is clamped in the clamping groove 61. At this time, the third threaded hole 711 will be aligned with the fourth threaded hole 63, and then the bolt 9 is used to connect to the third threaded hole 711 and the fourth threaded hole 63, so that the bolt 9 connects the bending portion 7 and the fixing seat together, so that when the overlock machine is not used for a long time, the protective cover 5 can stably protect the control panel 4.

[0037] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
