• (5) an integral drive rod that extends rearward from the center section,
• (6) a first pin bore located adjacent the first side ends and that extends through the upper section, the central protrusion and the lower section,
• (7) a second pin bore located adjacent the second side ends and that extends through the upper section and the lower section,
• (8) a first cam pin inserted through the first pin bore and through the cam slots on said first arm assembly,
• (9) a second cam pin inserted through the second pin bores and through the cam slot on said second arm,
• (10) means for securing said first and second cam pins,
• d) a drive-mechanism yoke having:
• (1) a central section having a front surface, a rear surface, an upper surface, a lower surface, a first side and a second side,
• (2) a device driving means cavity that extends inward from the rear surface of said central section,
• (3) a substantially centered drive rod bore that extends through said cavity,
• (4) a first upper section that integrally extends outward from the intersection of the upper surface and first side of said central section and having an outer end, an upper surface and a lower surface,
• (5) a first lower section that integrally extends outward from the intersection of the lower surface and first side of said central section and having an outer end, an upper surface and a lower surface, wherein a first slot is created between the lower surface of said first upper section and the upper surface of said first lower section,
• (6) a second upper section that integrally extends outward from the intersection of the upper surface and second side of said central section and having an outer end, an upper surface and a lower surface,
• (7) a second lower section that integrally extends outward from the intersection of the lower surface and second side of said central section and having an outer end, an upper surface and a lower surface, wherein a second slot is created between the lower surface of said second upper section and the upper surface of said second lower section,
• (8) a first pin bore that extends through said first upper section and said first lower section,
• (9) a second pin bore that extends through said second upper section and said second lower section, wherein after the first pin bore is aligned sequentially with the drive-mechanism yoke bore on the upper arm, the lower spacer and the drive-mechanism yoke bore on the lower arm, a first swivel pin is inserted and attached by an attachment means, and wherein after the second pin bore is aligned sequentially with the drive-mechanism yoke bore on said second arm and the second pin bore on said second lower section, a second swivel pin is inserted and attached by an attachment means,
• e) a device driving means that incorporates a linear actuating mechanism that attaches to the drive rod attachment end on said drive rod, wherein when said linear actuating mechanism is in a retracted position said first arm assembly and said second arm overlap into the closed interlocked position and conversely, when said linear actuating mechanism moves upward said drive rod moves upward causing said first and second cam pins to move along the respective cam slot to cause said first arm assembly and said second arm to spread outward,
• f) means for powering said device driving means,
• g) a forward handle with a first end having a first handle bore and a second end having a second handle bore, wherein the first handle bore is inserted over the first pin bore prior to inserting and attaching the first swivel pin, wherein the second handle bore is inserted over the second pin bore prior to inserting and attaching the second swivel pin, and
• h) a hand grip, attached by an attachment means, to a rear section of said device driving means.

A spreading, crushing or cutting device comprising:

• a) a first arm assembly having an upper arm and a lower arm each having a cam slot,
• b) a second arm having a cam slot, wherein said second arm slidably traverses between said upper and lower arms and interlocks therebetween,
• c) a drive yoke having a center section from where extends rearward a drive rod, a plurality of bores in alignment with the slots in said arms, a plurality of cam traversing structures inserted through the bores and interfacing with the cam slots on said arms, and means for securing said cam traversing structures,
• d) a drive-mechanism yoke having a central section having a device driving means cavity and a drive rod bore wherein said drive-mechanism yoke having dimensions to receive and retain said arms and,
• e) device driving means powered by a linear actuating mechanism attachable to the drive rod, wherein when said linear actuating mechanism is in a retracted position said first arm assembly and said second arm overlap into the interlocked position and conversely, when said linear actuating mechanism moves upward said drive rod moves upward causing said first and second cam traversing structures to move along the respective cam slot to cause said first arm assembly and said second arm to spread outward.
