Provided is an improved puncher structure connecting rods.
An interlocking mechanism of the utility model comprises a pivoting base arranged between a flywheel output gear and a crankshaft, the eccentric position of the pivoting base is opened with a shaft hole which is arranged for a driven end of the crankshaft passing exactly.
A driving gear is in pivoting assembly on the outer periphery of the pivoting base and is capable of rotatablely moving, one lateral of the outer periphery of the pivoting base is exactly meshed and driven with the flywheel output gear.
A crank moving-shaft is composed of two connecting rods which are in pivoting connection, one end of the crank moving-shaft is in assembly connection with the driven end of the crankshaft which passes through a hole of an eccentric shaft of the pivoting base and is fixed by a key.
A second end of the crank moving-shaft is in pivoting assembly on a preset lateral periphery portion which drives the gear, and the second end of the crank moving-shaft is in the state that the double crankshafts upwards lift a punch head when being arranged under the first end of the crank moving-shaft with an angle.
With the employment of the interlocking mechanism, the crankshaft is forced to do variable-speed circular motion when the crankshaft in rotating state. The utility model overcomes the defects of the known structure, and the utility model is capable of shortening the contacting time of the punch head and pieces during punching procedure, the damage caused by long-time high heat is reduced.
