That is, as shown in FIGS. 23 to 25, a U-shaped notch (26) is provided in the front part (24) of one holding piece (D), and the U-shaped notch separated by this notch (26). The frame (27) is sharply curved to form a fulcrum portion (21), and the meat wall portion (28) penetrating the U-shaped frame (27) is bent to form an action point portion (23), and further The side portion (25) is sharply curved to form a force point portion (22), and the one holding piece (D) is elastically suspended on the other flat plate-shaped holding piece (E). .

<< Problems to be Solved >> However, the above structure has the following problems.

I. The fulcrum portion, the force point portion, and the action point portion of one of the sandwiching pieces are formed by sharply bending or bending a flat plate, so that the structure and shape become complicated and the manufacturing cost becomes expensive.

B. Since the spring elasticity generated by the sharply curved U-shaped frame is weakened at the curved portion of the force point portion and the bent portion of the action point portion and then transmitted to the action point portion, the clamping force at the action point portion is weakened.

C. As described above, the fulcrum portion, the force point portion, and the action point portion of one of the sandwiching pieces are formed by sharply bending or bending the flat plate, respectively, so these curved portions and bent portions are damaged early. In addition to being easily damaged and inferior in durability,
The elasticity of the curved portion or the like is likely to decrease early, and the clamping force at the point of action cannot be maintained constant for a long period of time.

<< Means for Solving the Problems >> The present invention is configured, for example, as shown in FIGS. 1 to 22 to achieve the above object.

That is, a U-shaped notch (7) is formed in one of the clamping pieces (A), a meat wall surrounded by the U-shaped notches (7) is formed as a leaf spring (4), and the other clamping piece (7) is formed. A spring insertion hole (8) is provided on the side of the action point (3) rather than the fulcrum (1) of (B), and this spring insertion hole (8)
