The left side of the body 2 is fixedly connected to the limit plate 15, and the pull rod 146 is located on the surface of the limit plate 15, so that the pull rod 146 can be auxiliary limited to prevent the connecting plate 145 and the movable rod 142 from moving downwards at will.

A guide plate 24 is fixed in front of the bottom of the frame 1, and the guide plate 24 is located between the through slot 12 and the collection box 13, so that the cloth can be guided and conveniently dropped into the collection box 13.

A dust-proof net 22 is provided inside the right side of the dust collecting box 211, and the dust-proof net 22 is located on one side of the suction end of the fan 212. This can intercept lint and prevent them from entering the inside of the fan 212 and affecting subsequent use.

A dust box 25 is movably connected to the interior behind the dust box 211, and a handle is provided on the surface of the dust box 25, so that the lint collected inside the dust box 211 can be pulled out uniformly.

Working principle: When using, first wind one end of the needle thread through the threading rod 17 on the surface of the threading groove 18, and then push the fixed plate 19 to the left, so that the left end of the threading rod 17 enters the thread hole inside the needle head, thereby achieving To achieve the effect of quick threading, the fabric can then be piled up inside the prevention box 6, and then one end of the fabric can be passed between the two conveying rollers 4 and pulled into the sewing position of the machine body 2, and then the pull rod 146 can be rotated. The leveling roller 143 is positioned on the top surface of the fabric to level the fabric. Then the motor 7 can be started to drive the first driving wheel 8 to rotate. At the same time, the first driven wheel 9 is driven to rotate through the belt, and passes through the body 2 The needle is driven to sew the fabric, and during the sewing process, as the motor 7 is driven, the two gear sets 5 are driven to rotate through the transmission structure 10, and at the same time the two conveying rollers 4 are driven to rotate, thereby moving the fabric forward. During the transportation and sewing process, the thread ends can be adsorbed by the dust suction structure 21, and as the cloth is transported, the front end of the cloth will fall into the inside of the collection box 13 through the slot 12, thereby preventing the cloth from contacting the ground. Make contact.
