The main body 80 is fastened pivotally with the projection 41 of the first toggle 40 and is provided at the lower end thereof with a threaded rod 82 extending toward the second toggle 42. The threaded rod 82 is received in the first through hole 45. The adjustment button 84 is disposed in the second through hole 46 and is provided at the center thereof with a threaded hole 85 which is coaxial with the first through hole 45. The threaded rod 82 is provided with an arresting nut 86.
As shown in FIG. 2, there is a V-shaped notch 90 located between the first jaw 22 and the second jaw 24 which are joined together. The arresting nut 86 is first loosened before the adjustment button 84 is rotated to force the second toggle 42 to move to the right. In the meantime, the lower end of the second jaw 24 is actuated by the second bolt 43 to enable the second jaw 24 to swing on the locating bolt 26 to the right for an appropriate angle so as to cause the second blade 23 to move to the left to become parallel to the first blade 21, as shown in FIG. 3. Thereafter, the distance between the first jaw 22 and the second jaw 24 can be reduced by turning the locating bolts 26. As a result, the first blade 21 and the second blade 23 are joined together intimately, as shown in FIG. 4.
In order to secure the adjusting member 18, the main body 80 and the second toggle 42 are provided therebetween with a screw 87.
As shown in FIGS. 5 and 6, the adjusting member 18 is provided with a wedge-shaped rib 88 for preventing the first toggle 40 and the second toggle 42 from swaying.
