Vise

A vise comprising:

• a fixed block;
• a movable head movably attached to said fixed block;
• a rod including a rod threaded portion and a rod non-threaded portion;
• a ratchet secured to said fixed block and including a rotatable ring which jointly rotates with said rod, said rotatable ring including a rotatable ring opening and disposed on said rod with said non-threaded portion disposed through said rotatable ring opening, said rotatable ring rotatable in first and second opposite circumferential directions, said rotatable ring including a first rotatable portion having an external surface having a first rotatable portion ramp and a second rotatable portion having an external surface having a second rotatable portion ramp, said first rotatable portion ramp inclined outwardly in the first circumferential direction and said second rotatable portion ramp inclined outwardly in the second circumferential direction;
• threaded portion engagement elements secured to said fixed block and selectively engageable with said rod threaded portion such that in a first condition said threaded portion engagement elements are engaged with said rod threaded portion and rotation of said rod causes said movable head to move relative to said fixed block and in a second condition said threaded portion engagement elements are disengaged from said rod threaded portion and said movable head is freely movable relative to said fixed block by sliding said movable head along said rod;
• and
• a toggle connected to said ratchet and said threaded portion engagement elements, said toggle comprising a switch rod and a trigger having a body defining an opening for receiving said switch rod, said trigger having a first node and a second node, said trigger configured to toggle between a first trigger position in which said first node can rotatably engage said first rotatable portion ramp and the second node is spaced from and cannot rotatably engage said second rotatable portion ramp and a second position in which the first node is spaced from and cannot rotatably engage said first rotatable portion ramp and the second node can rotatably engage the second rotatable portion ramp, wherein, rotation of said rotatable ring causes said toggle to move said threaded portion engagement elements between said first condition and said second condition.
