10. The use method of the special-shaped surface spring auxiliary pushing mechanism for hardware wrench machining according to any one of claims 1 to 9 is characterized in that: comprises the following steps of (a) carrying out,

s1, adjusting the position of the limit plates (47), namely pulling out the locating pin (50) to support the locating block (49) to move, driving the limit plates (47) to move by the locating block (49) through the connecting column (48), adjusting the distance between the two limit plates (47) to be slightly larger than the width of the hardware wrench, and inserting the locating pin (50) to penetrate through the locating block (49) to enter a locating hole at the position at the moment;

s2, adjusting the initial inclination angle of a second clamping plate (5), rotating a second handle according to the inclination angle of the inclined plane of the side face of the hardware wrench, driving a screw rod (33) to rotate by the second handle through a third rotating shaft (34), enabling a sliding seat (35) to move on the surface of the screw rod (33) under the limiting action of a guide rod (38) and a guide block (37), driving a mounting plate (31) to move by the sliding seat (35) through a connecting block (36), driving a sliding rail (30) to move by the mounting plate (31), driving the second clamping plate (5) to rotate under the action of the sliding rail (30) and a second roller (29), and adjusting the initial inclination angle of the second clamping plate (5) to the first clamping plate (4) is realized;

s3, feeding, sequentially putting the hardware wrenches on the conveying belt (43) where the limiting plates (47) are located, starting the servo motor (46) to drive the conveying belt (43) to move, conveying the hardware wrenches, and stopping the servo motor (46) when the first hardware wrench moves to a processing station where the middle position of the two clamps (3) is located;

s4, clamping and pushing the hardware wrench tightly, pulling the limiting rack plate (24) to slide in the first sliding groove through the first sliding block (25) and extruding the third spring (26) to shrink, so that the limiting rack plate (24) and the gear (23) are not meshed any more, at the moment, rotating the first handle to drive the first rotating shaft (13) to rotate, driving the second rotating shaft (16) to rotate under the meshing action of the first bevel gear (15) and the second bevel gear (17), driving the second rotating shaft (16) to rotate the rotating disc, enabling the two connecting rods (20) to approach each other under the action of the 8-shaped rotating disc (18) and the first rolling wheel (19), further driving the two connecting plates (11) to approach each other, enabling the two connecting plates (11) to drive the two clamps (3) to approach each other through the guide columns (9), and enabling the first clamping plate (4) to rotate in motion and attach to the inclined plane of the hardware wrench simultaneously under the action of the arc, when the movable clamping plate (8) is attached to the hardware wrench, the first handle continues to rotate, the first spring (6) receives an acting force generated by extrusion and contraction and acts on the movable clamping plate (8), the hardware wrench can be further clamped and fixed, and the limiting rack plate (24) is loosened to clamp the gear (23) under the action of the third spring (26) so as to avoid looseness, so that the hardware wrench can be processed;
