When in such tight engagement the wedges 26 and 27 coact tomaintain end 23 of lever 21 in the proper position for the lever arrangement to properly lock the tool onto the object when such arrangement is actuated. Wedge 27 is then slid -rearw-ardly along back wall 22 of the handle into pocket 26 until it tightly engages wedge 24 such as shown in FIGURE 3. Then, as shown in FIGURE 3, the clamping jaws are placed about an object 31 to be clamped, and the pressure against lever 18 is released so that spring 28 urges jaws 13 and 14 toward one another to engage the object. This causes wedge 24 to move inwardly further into pocket 26, and jaw 14 to be thereby pulled away from jaw 13. As shown in FIGURE 2, the user first urges pressure lever 18 rearwardly toward handle structure 12 in the directionindicated by arrows 29. The simple manner in which the tool can be used to grip and clamp an object is depicted in FIGURES 2, 3, and 4. toggle levers, gears with self-locking toggle levers
