[0006] In one embodiment of the utility model, the locking mechanism includes a locking block, a locking plate and a positioning pin. The side of the locking block is "L"-shaped. The locking block and its bottom surface form a groove. The locking block is located in the groove. The positioning pin passes through the locking block and is connected to the locking block.

[0007] In an embodiment of the present invention, an elastic member is provided between the locking plate and the positioning pin.

[0008] In an embodiment of the present invention, at least three locking mechanisms are disposed on the upper surface of the pressure plate fixing plate and around the second mounting groove.

[0009] In an embodiment of the present invention, two locking mechanisms are respectively disposed on the upper surface of the bottom plate fixing plate and on both sides of the first mounting groove.

[0010] In one embodiment of the utility model, ear pieces are provided on both sides of the bottom plate, positioning holes are processed on the ear pieces, and positioning columns matching the positioning holes are provided on the bottom plate fixing plate.

[0011] In one embodiment of the present invention, the pressure plate fixing plate is hinged to the bottom plate fixing plate by a hinge.

[0012] In an embodiment of the present invention, a handle is provided on the pressing plate fixing plate.

[0013] In an embodiment of the present invention, a plurality of strong magnetic holes surrounding the second mounting groove are formed on the pressure plate fixing plate.

[0014] As described above, the quick-change sewing clamp for the airbag initiator port of the utility model has the following beneficial effects: the utility model respectively fixes the base plate and the base plate fixing plate, and the pressure plate and the pressure plate fixing plate through a locking mechanism, thereby realizing the quick replacement of different sewing pressure plates and pattern base plates; and then through the rotation and fitting of the base plate fixing plate and the pressure plate fixing plate, the sewing pressure plate and the pattern base plate can be quickly connected to ensure the timeliness when switching different pattern projects; compared with the integral clamp, the quick-change sewing clamp only needs to store the sewing pressure plate and pattern base plate of each project; the quick-change sewing clamp has the advantages of quick replacement, versatility, consistency, and less storage space.
