A movable arm is provided with a screw hole at the other end thereof, and a tightening male threaded rod is screwed into the screw hole of the movable arm, and a clamping portion provided at an appropriate position between the fixed arm and the male threaded rod. A clamp configured to clamp an object is used.

FIGS. 8 to 11 are examples of this, and this clamp 20 includes a fixed arm 23 in which a fixed bar 21 and a rail part 22 are integrally provided in an L shape, a movable arm 24, and a male threaded rod 25 for tightening. It consists of each member. Each of these members will be explained below.

The fixing bar 21 of the fixing arm 23 has a concave portion 27 formed in the middle thereof so as to have an I-shaped cross section. The front half of the recess 27 is an engaging portion 27a with a corrugated bottom surface. The lower surface of the fixing bar 21 is formed into a planar shape, and the tip thereof forms a wide clamping part 28. The rail portion 22 is a vertically long plate material with grooves 30 provided along the entire length on both sides of the central portion, and has both front and rear end surfaces 31, 3.
1' is provided with continuous serrated notches 32.
A locking portion 33 for preventing the movable arm 24 from falling off is provided at the lower end of the rail portion 22.

Like the fixed bar 21, the movable arm 24 also has a recess 35 in the middle, a mounting hole 36 for loosely fitting the rail portion at one end, and a screw hole 37 for tightening at the other end. The mounting hole 36 is the rail 22
The movable arm 24 is formed as a hole slightly larger than the outer shape of the rail 22 so that the movable arm 24 can freely slide on the rail portion 22. A groove-shaped recess 38 is provided in the center of the mounting hole 36 along its inner wall. Further, a screw hole 39 is provided in the upper and lower positions on the back side of the peripheral edge of the mounting hole 36,
This screw hole 39 partially communicates with the mounting hole 36. A screw 40 is screwed into this screw hole 39, but this screw 40 does not have a head larger in diameter than the threaded portion, and in the illustrated example, a hexagon socket head bolt is used. In the screwed state, the threaded surface of the screw 40 is partially exposed within the mounting hole 36. Note that this screw 40 may be provided at the lower front surface of the mounting hole 36.

The male threaded rod 25 has a wooden grip 43 fixed to the rear end of a threaded member 42 having a threaded portion 42a that is threaded into the threaded hole 37 of the movable arm 24.
