Description

Technical Field

[0001] The utility model belongs to the technical field of sewing machines, in particular to a sewing machine shear blade which is easy to replace. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. It can sew products such as fabrics, leather, plastics and paper, and has derived various sewing track forms.

[0003] The cutter head of the MO-6900 series industrial stitching machine is fixed to the fixing plate by bolts. It needs to loosen the bolts with the help of tools such as screwdrivers to disassemble and replace the cutter head. This operation method of replacing the cutter head is relatively cumbersome. In order to solve the above problem, we propose a stitching machine shear blade that is easy to replace. Utility Model Content

[0012] 1. Tilt the block at a certain angle and place it inside the circular groove. Press the fixing plate. At this time, the spring is in a compressed state. Rotate the fixing plate to make the limiting cylinder clamp into the limiting groove for limiting. Release the fixing plate. At this time, the spring is in an expanded state and the free end contacts the bottom of the inner wall of the circular groove. Through the card-fitting cooperation between the block and the limiting column and between the limiting cylinder and the limiting groove, the block can be fixed in position to a certain extent. Press the fixing plate. At this time, the spring is in a compressed state. Rotate the fixing plate at a certain angle to make the limiting cylinder disengage from the limiting groove and the block disengage from the limiting column. Release the fixing plate.
