Specifically, Figure 2 As shown, a limiting member is provided between the side of the cylinder 201 and the L-shaped plate 202 , and the limiting member is used to limit the position of the L-shaped plate 202 during the lifting process, thereby reducing the deviation of the L-shaped plate 202 during the lifting process.

[0043] Further, such as Figure 2 As shown, the limiting member includes a slide rail 203 fixedly mounted on one side of the cylinder 201, the outer surface of the slide rail 203 is slidably connected to a slide seat 204, and the side of the slide seat 204 is fixedly connected to the L-shaped plate 202. Through the mutual cooperation between the slide rail 203 and the slide seat 204, the lifting process of the L-shaped plate 202 can be limited, thereby improving the stability of the L-shaped plate 202 during the lifting process.

[0044] Example 2 further optimizes the overalls sewing auxiliary device provided in Example 1. Specifically, the supporting mechanism 1 includes a supporting member, the supporting member is connected to a connecting member, and the connecting member is connected to the cylinder 201.

[0045] Further, such as Figure 1 As shown, the support member includes a mounting plate 101 , one side of the mounting plate 101 is fixedly connected to a support plate 102 , and the mounting plate 101 is used to support the support plate 102 .

The connection between the cylinder 201 and the support plate 102 can be achieved through the sliding sleeve 103, and the sliding sleeve 103 can move on the outer surface of the support plate 102, thereby adjusting the position of the pressure wheel 303.

[0048] Further, such as Figure 3 As shown, the side of the sliding sleeve 103 is threadedly connected with a fixing bolt 104, one end of the fixing bolt 104 penetrates into the sliding sleeve 103 and contacts the fixing bolt 104. The position of the sliding sleeve 103 can be fixed by the fixing bolt 104, and the sliding sleeve 103 can be moved after loosening the fixing bolt 104.

[0049] The use process of the auxiliary device for sewing overalls provided by the utility model is as follows:

[0050] Reference Figure 4 , install the mounting plate 101 on the sewing machine by bolts so that the pressure wheel 303 corresponds to the position of the sewing machine needle, the style of the overalls and pockets is as follows Figure 5-Figure 7 As shown, the cylinder 201 first drives the support rod 3 to rise through the L-shaped plate 202, thereby causing the pressing wheel 303 to rise and place the cloth in the corresponding position. Then, the cylinder 201 drives the support rod 3 to descend so that the pressing wheel 303 pre-presses the sewing part of the cloth, so that the sewing part of the cloth remains flat.
