（２）の交換が簡単に出来て縫製作業の能率がよく なるものである[Detailed Description of the Invention] The present invention allows the presser foot of a sewing machine to be easily replaced.
Since the presser bar (1') was designed to be tightened, screws had to be tightened with a screwdriver, which was troublesome.In a sewing factory where labor is divided into processes, this troublesomeness would not be present, but in a tailor's shop, there was only one worker. In order to complete a custom-made item with one piece, the presser foot (2') must be replaced at each step, which is time-consuming.For example, even if you are sewing a dress, the process will change about eight times. The work will be easier if you change the presser foot to a more suitable one.In the present invention, the presser foot (2) has a structure in which the presser bar (1) fits into the presser foot (2). If you place your hand directly under the presser foot (1) and lower the presser foot (1), it will fit properly. If this continues, the presser foot (2) will fall out if you raise or lower it during sewing. All you need to do is use a simple spring or magnet to prevent it from falling off. To remove the presser foot (2), pull the presser foot (1) higher than the range in which it moves up and down during normal sewing work, and press it against the stopper (4). Place the presser foot (2) on it, then pull up the presser foot bar (1) again to remove the presser foot (2).In this way, the presser foot (2) can be easily replaced and the efficiency of sewing work will be improved. is
