Rotate, drive second connecting rod 16 to move up and down, and then drive second shearing hinged with second connecting rod 16
Arm 17 swings around shear arm support shaft 24, drives the second activity being arranged on the second shear arm 17
Cutter 18 and be indirectly fixedly mounted in frame 1 second fix cutter 19 and relative motion occur, through
Two reinforcing bars 23 fixing cutter 19 are cut off.
In the present invention, the first mono-directional overrun clutch 8 and the second mono-directional overrun clutch 14 are all folk prescriptions
To clutch, the positive and negative rotation of speed reducer output shaft, the first mono-directional overrun clutch 8 and second unidirectional super
More in clutch 14, only one of which drives cutting mechanism 27 action to complete shear reinforcement, can realize an electricity
Machine reductor drives an execution shear reinforcement in two cutting mechanisms respectively by selecting positive and negative rotation
Action.Therefore, in haulage gear 29, the reinforcing bar 23 driven by traction wheel 21 and pinch roller 22 just may be used
To realize two cutting to length.
