The handle 31 of the rotary lever 28 is rotated toward the adjustment plate 17, and the adjuster 23 slides toward the adjustment plate 17 while resisting the urging force of the pressing spring 29. The rod 13 slides in the direction away from the base 2 with the movement of the adjuster 23, and a sufficient interval can be provided between the tip of the base 2 and the rod 13 to sandwich the work 3.

When the space between the base 2 and the rod 13 is sufficiently opened, the work 3 is set. Stopper plate 9
Is used when the work 3 cannot be stably sandwiched only by the base 2 and the rod 13.

When the handle 31 of the rotary lever 28 is returned to its original position, the adjuster 23 moves toward the support plate 16 by the urging force of the pressing spring 29, and the rod 13 also slides toward the base 2. Thereby, the rod 13 and
The work 3 can be sandwiched between the inner wall surface 4 of the base 2 and the stopper plate 9. Depending on the shape of the work 3, a rod 13 having a flat tip or a curved rod may be used.

Since the distance between the tip of the base 2 and the base 2 is narrow or wide, the screw 26 of the adjuster 23 is loosened to change the mounting position of the adjuster 24 with respect to the rod 13 before use.

When the pinching force of the rod 13 is too weak or too strong, the urging force of the pressing spring 29 is adjusted by the adjusting bolt 20. When the adjustment bolt 20 is rotated to approach the adjuster 23 side, the urging force of the pressing spring 29 increases. Conversely, when the distance between the adjuster 23 and the adjustment bolt 20 is increased, the urging force of the pressing spring 29 can be reduced.

It should be noted that the above adjustment alone is not sufficient, and when the force of the pressing spring 29 is too weak or too strong, it is used in place of the spare pressing spring 18. In the above description, the work from one side (lower side in FIG. 2) has been described, but the work can be performed from the other side (upper side in FIG. 2). In that case, the stopper plate 9 and the rotating lever 2
Attach position 8 to the opposite side.

As described above, according to the present invention, the work 3 can be quickly and easily fixed or removed by rotating the rotary lever 28, and the work 3 can be mass-produced quickly, reliably and stably. Can be processed and ground.

In this spring vise, a base plate 40 is formed of a plurality of members, and a base 42 is provided between two parallel base plates 41 made of iron and having a thickness at one end (left side in FIG. 4). The support plate 16 is sandwiched at the center and the adjustment plate 17 is sandwiched at the other end, and are fixed to each other with bolts 43.

The base 42 serves not only as a spacer for the base plate 41 but also as an inner wall surface of the base 42 and the base 45.
To form a sign bar with a block gauge (not shown) interposed therebetween. Also, as shown in FIG. 7, the tip of the screw 44 is
It can protrude to the side and give a predetermined angle. In the present embodiment, any of the angles described above may be used.

The base 45 is inclined at an angle of up to 15 degrees toward the other end (right side in FIG. 4) with the lower end as a fulcrum (however, the inclination angle is not limited to 15 degrees at maximum). In the method of locking the base, there is an arc-shaped depression inside the lower end of the base 42, and the projection 52 at the lower part of the base 45 is fitted into this depression.
Is pressed against the base 42 and locked (see FIG. 9). The radius of the projection 52 of the base 45 is the following base 45
Are slightly larger (for example, the difference is about 1 mm) than the radius of the arc-shaped projection 46 formed on the upper outer portion of the upper surface.

An arc-shaped projection 46 is projected from the upper outer portion of the base 45 so that when the block gauge is sandwiched between the base 42, the size of the block gauge can be adjusted regardless of the inclination angle of the base 45. With a corresponding spacing, you can get the exact angle as a sign bar.

A mounting table 47 for mounting the work 3 is formed on the central inner wall of the base 45 so as to protrude therefrom. In addition to the operation of mounting the work 3, the mounting table 47 performs an operation of pressing a posture holding spring 48 that holds the posture of the base 45 as described later.
