    摘要： Disclosed is a stapler including: a body including a fixed plate provided on a top portion of one end thereof and formed with a needle insertion hole, and a lower thread supplier provided below the fixed plate to feed a lower thread through the needle insertion hole; and a presser which is connected to the other end of the body at one end thereof by a rotating shaft, and includes a fastening needle installed to the other end to stitch an object and penetrating the needle insertion hole together with an upper thread, in which the object is stitched with the upper thread and the lower thread when pressure is applied to the presser. Since the sheets of paper are bound with the thread, it is possible to prevent the paper from being discolored or crumbed.
