Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0025] As shown in Figure 1 - Figure 4 The present application provides an overlock device for body shaping clothes with a broken thread self-stopping mechanism, which comprises an overlock machine 1, a stop motion mechanism 2 and a clamping plate 201 arranged on the side wall of the overlock machine 1, and further comprises

[0026] Specifically, as shown in Figure 2 The rotating assembly 3 is arranged between the overlock machine 1 and the clamping plate 201, and the rotating assembly 3 is used for rotating the clamping plate 201. The rotating assembly 3 comprises a connecting shaft 301 fixedly connected to the side wall of the stop motion mechanism 2, and the clamping plate 201 is rotatably connected to the outer wall of the connecting shaft 301. The side wall of the clamping plate 201 movably inserts the fixed rod 303, and the outer wall of the connecting shaft 301 fixedly connects the side plate 302. Two groups of side plates 302 are distributed on both sides of the clamping plate 201. By arranging the rotating assembly 3 between the overlock machine 1 and the clamping plate 201, and moving the fixed rod 303 on the rotating assembly 3, the clamping plate 201 can be quickly rotated downward, and the thread scraps stuck in the clamping port can be cleaned, thereby improving the convenience of cleaning.

[0027] A plurality of fixed grooves 3031 are formed in the side wall of the clamping plate 201, and the fixed rod 303 penetrates the side wall of the side plate 302 and is inserted into the inside of the fixed groove 3031. By rotating the screw rod 305 inward, the fixed rod 303 can be moved toward the clamping plate 201. At this time, the fixed rod 303 will be inserted into the fixed groove 3031 on the clamping plate 201 for fixation.

[0028] Specifically, as shown in Figure 3 The end of the fixing rod 303 is fixedly connected with a connecting plate 304, a sliding groove 3041 is formed in the two sides of the connecting shaft 301, the connecting plate 304 is slidingly connected in the inside of the sliding groove 3041, a lead screw 305 is rotatably connected to the side wall of the connecting plate 304, and the lead screw 305 is threadedly connected to the end of the connecting shaft 301. By rotating the lead screw 305 outward, the fixing rod 303 can be moved to be retracted in the inside of the side plate 302, and at this time, the clamping plate 201 can be rotated.

[0029] Specifically, as shown in Figure 4 The side wall of the clamping plate 201 is provided with a limiting assembly 4, and the limiting assembly 4 is used for limiting the thread. The limiting assembly 4 further includes a limiting frame 401 fixedly connected to the side wall of the clamping plate 201, and a limiting plate 402 is formed in the side wall of the limiting frame 401. By arranging the limiting assembly 4 on the side wall of the clamping plate 201, the thread can be clamped and hovered by passing through the limiting frame 401 and the limiting plate 402 on the limiting assembly 4, and the stability of the thread during hovering is further improved.

[0030] The end side of the limiting plate 402 is fixedly connected with a connecting piece 403, a connecting groove 4031 is formed in the two sides of the limiting frame 401, the connecting piece 403 is slidingly connected in the inside of the connecting groove 4031, a return spring 404 is fixedly connected to the side wall of the connecting piece 403 and fixedly connected in the inside of the connecting groove 4031, and flexible pads 405 are fixedly connected to the sides corresponding to the limiting frame 401 and the limiting plate 402.
