7. The saddle stitcher as recited in claim 6 wherein: the first side and the second side of the bearing plate, which are adjacent to the front end, are provided with positioning pieces and positioning mechanisms for fixing the positioning pieces on the bearing plate, and the positioning pieces are used for limiting the positions of the objects to be bound.

8. The saddle stitcher as recited in claim 6 wherein: the rear end plate of the bearing plate is bent to enable the bearing plate to be provided with a first supporting surface and a second supporting surface, and the first supporting surface and the second supporting surface are used for supporting objects to be bound; when the bearing plate is in a horizontally bound state, the first supporting surface is horizontal, when the bearing plate is in a saddle-bound state, the contact position of the first supporting surface and the second supporting surface is vertically upward, and the first supporting surface and the second supporting surface are in a ^ shape.

9. The saddle stitcher as recited in claim 6 wherein: the mounting base comprises a supporting base, a hanging plate, a first mounting column and a second mounting column, wherein the first mounting column and the second mounting column are arranged on the supporting base, the middle of the first mounting column is hinged to the connecting mechanism, the hanging plate is arranged at the top of the first mounting column, the hanging plate is used for being hung with the bearing plate, the upper end of the second mounting column is located above the hanging plate, and the binding mechanism is arranged at the upper end of the second mounting column so as to be located above the bearing plate.

10. The saddle stitcher as recited in claim 6 wherein: the mounting seat is formed by fixedly combining a first seat body and a second seat body, the first seat body and the second seat body respectively comprise a first mounting arm, a second mounting arm and a supporting arm, the first mounting arm on the first seat body and the first mounting arm on the second seat body are combined to form a first mounting column, the second mounting arm on the first seat body and the second mounting arm on the second seat body are combined to form a second mounting column, and the supporting arm on the first seat body and the supporting arm on the second seat body are combined to form a supporting seat.
