Is executed. On the other hand, when the operator rotates the rotary nut member 115 in the other direction, the screw rods 110 on both sides are spaced apart from each other in the outward direction of the rotary nut member 115, the binding release action is performed.

However, such a conventional turnbuckle has only a function of binding or releasing a binding object by mutually approaching and spaced apart from each other in the longitudinal direction according to the rotation of the rotating nut member, and there is a problem in that the binding object cannot be measured. .

As a result, when the rotary nut member is excessively rotated in the binding direction, that is, when an excessive tensile load is applied to the turnbarl, problems such as breakage of the turnbuckle or breaking of the rope or wire occur.

Accordingly, if the tensile load acting on the turnbuckle can be simply confirmed, proper binding of the binding object using the turnbuckle may be possible, thereby preventing breakage of the turnbuckle and damage of the rope or wire.

Numerical patterns 33 formed in the longitudinal direction on the measuring piece 31 to display the tensile load based on the tensile strain of the rotating nut member 10 and the rotating nut member 10 intersecting the measuring piece 31. It may be provided as an instruction pattern 35 formed on the other side in the width direction.

In the turnbuckle 1 according to the present invention having the above configuration, for example, as shown in FIG. 7, the rotating nut member 10 is rotated in the binding direction in the process of binding the object and the binding object A by using a wire. When both screw rods 20 approach each other, a tensile load is applied to both screw rods 20 and the rotating nut member 10.
