Pressing this fifth embodiment, the U-shaped frame 1 fixed structure for the base member 10 is screw fitted to the slide block 14 and the U-shaped frame 1 which is accommodated in a U-shaped frame 1, as shown in FIG. 15 It is configured to be fixed by screws 15.

That is, in FIGS. 11 and 15, reference numeral 16 denotes a lock screw, and as shown in FIG.
4, the inner edge of the tapered fitting hole 14a is pressed against the side surface of the lock screw 16 when the slide block 14 moves to the left in the illustrated example. The engagement protrusion 14b formed at the base of the block 14 and the fitting groove 10a of the base member 10 are engaged with each other so that both are fixed.

Therefore, according to the fifth embodiment, the fixing position of the U-shaped frame 1 is not limited, and can be fixed at an arbitrary position in the left-right direction in FIGS. In FIG. 15, reference numeral 15a denotes a screw lock rubber;
5 is pressed against the side surface to prevent loosening due to external force.
Reference numeral 14c denotes a lock rubber, and the slide block 1
4 restricts free movement. Reference numeral 15d denotes a female screw portion, and the holding screw 15 is screw-fitted.

The fifth embodiment differs from the first to fourth embodiments in that the housing portion of the cam 7 is different from the first to fourth embodiments in that a cover 1d for the cam 7 is formed at the upper end of the U-shaped facing piece 1b.
Therefore, according to this configuration, the support state of the cam 7 is more firm, and it is possible to prevent an accident of rattling or detachment. The cam cover member 1d is not limited to this embodiment, but can be similarly implemented in other embodiments.

11 and 15, reference numeral 17 denotes an article pressing member, which is attached to the tip of the rod 3 by a screw 18. The article holding member 17 is a rod 3
The distal end face is attached when the article cannot be securely fixed, and is fixed with a screw 18 via a washer 19 as shown in FIG.

The article pressing member 17 of the present invention desirably has appropriate elasticity and strength. For example, engineering plastics or the like is preferably used, and specifically, a member made of Duracon is used. This article pressing member 17 can also be applied to the other embodiments 1 to 4 described above.
Further, in the fifth embodiment, the stopper 13 provided on the base 11 is rotatable about the pin 19 so that it can be folded as shown by a dotted line when it is obstructed by the processed article or when it is unnecessary. Have been.
