As the material of the trowel 4, in addition to the above-mentioned synthetic resin, an appropriate metal powder may be mixed into the synthetic resin to increase the rigidity of the synthetic resin. Further, the engaging claw 7 is not limited to the upper and lower end peripheral surfaces of the trocar 4 but can also be provided on the side surfaces thereof. By doing so, a long engaging claw 7 can be obtained, The contact surface pressure during is increased, so that the trowel 4 can be fixed more firmly.

The adjustment seat thus configured is roughly composed of two parts, a trowel 4 and an adjustment fitting 9 also serving as a reception, which is a large part of the trowel, the receiver, the adjustment fitting and the mounting screw. The number of parts is reduced as compared with the conventional four-part structure, the structure is simplified, the labor for manufacturing parts is reduced, the cost can be reduced, and the adjusting bracket 9 is integrated. The receiving piece 13 is made of a small piece shorter than the length of the troyoke chamber 5, which is very small as compared with the conventional pedestal mounted on the surface of the troyoke 4, and the material cost is reduced accordingly. In addition, it is possible to suppress a reduction in appearance due to exposure of the portion.

On the other hand, since the troyoke 4 is formed at a time with a synthetic resin, the processing step and labor are greatly reduced as compared with the conventional one in which a steel plate is press-formed and bent, and a screw hole is punched at a predetermined position. Improve cost reduction.

Next, when installing the adjustment seat of the present invention,
The same shape as the front shape of the troyoke 4 at a predetermined position of the frame body 1,
That is, the oval mounting hole 2 is formed, and the depth of the hole 2 is formed to be substantially the same as the height of the trowel 4. Then, the bottom surface 4b of the molded trowel 4 is positioned in the mounting hole 2 and is driven by a suitable tool such as a wooden hammer, or is pressed by using a suitable pressing means using a fluid pressure cylinder.

In this manner, the engaging claws 7, 7 are guided by the tapered surfaces 7a, 7a and are pushed into the mounting hole 2, and the tips thereof are engaged with the inner wall of the mounting hole 2. At this time, the engaging claw 7 receives a pressing force corresponding to the protruding amount h to the mounting hole 2 and is pressed and bent inward against its own elasticity. Then, the trowel 4 is further pushed in, and when the bottom surface 4b contacts the bottom surface of the mounting hole 2, the pushing operation is stopped.

As shown in FIG. 3, the trowel 4 pushed into the mounting hole 2 is bent inward at the tips of the engaging claws 7, and the edges engage with the inner surface of the mounting hole 2. I have. Therefore, the trowel 4 is held in the mounting hole 2 by a strong contact surface pressure formed between the distal end portions of the engagement claws 7 and the inner surface of the mounting hole 2, and the detachment and play of the trowel 4 are prevented. To prevent. In addition, since the mounting of the trowel 4 is performed by pushing it into the mounting hole 2, the operation is extremely simple and quick as compared with a conventional method of screwing the trowel.

After attaching the trocar 4, the adjusting bracket 9 is housed in the bottom of the trocar chamber 5, the elongated hole 10 is positioned in the screw hole 8, and the receiving piece 13 integral with the bracket 9 is formed with the concave grooves 17,3.

And the adjustment fitting 9 is fixed.

Thus, the adjustment seat mounted on the frame 1 is as shown in FIGS. 1 to 3, wherein the front surface 4a of the trocar 4 is exposed on the frame 1, and these are arranged on the same plane. On the surface of the troyoke 4, there is no mounting screw which has been frequently used, and since the receiving piece 13 is smaller than the troyoke 4 and suppresses the texture of the metal, the appearance of the adjusting pedestal and its surroundings is improved. .

When the adjustment seat is used, the adjustment screw 11 is loosened, the adjustment screw 11 is moved in the longitudinal direction of the elongated hole 10, and the gap e between the upright piece 12 and the latch 18 is adjusted. When the adjustment amount in one side direction is large, the adjustment is performed by inserting one end of the adjustment fitting 9 into the slot 14. When removing the troyoke 4 once installed, an appropriate tool such as a screwdriver is inserted into the slot 14 from the outside of the troyoke chamber 5 without removing the adjustment fitting 9, and the bent portion of the seat 13 is removed. If you squeeze the fulcrum, you can remove it.
