Specifically, the expansion extending in a direction in which the auxiliary coupling hole 614 extends from the expansion groove and the expansion groove on one surface in a direction in which the auxiliary coupling bolt 661 of the auxiliary coupling flange portion 613 is inserted. The extension groove is formed.

At this time, the extension groove and the extension extension groove are composed of grooves of a concave shape, not the shape of a through hole.

The auxiliary coupling hole 614 is formed on one surface of the extended groove and the extended extension groove in a concave direction.

At this time, the extended extension groove has a smaller size than the extended groove, and the extended groove is the same shape and diameter as the auxiliary coupling nut 664 coupled to the auxiliary coupling bolt 661, or slightly larger than the same shape. It has a shape with a diameter.

Accordingly, after the auxiliary coupling bolt 661 and the auxiliary coupling nut 664 are combined, two opposite synthetic resin pipes to repair the synthetic resin pipe 10, the packing 20, or the clamp unit 30, etc. In order to open the space between 10), it is not necessary to manipulate the auxiliary coupling bolt 661 and the auxiliary coupling nut 664, thereby providing convenience in operation.

If the secondary coupling bolt 661 and the secondary coupling nut 664 are combined, then, when an external force or external force is applied and lowered based on the drawing, the auxiliary coupling bolt 661 and the secondary coupling The nut 664 maintains a stable coupling state,

When the auxiliary coupling bolt 661 and the auxiliary coupling nut 664 are positioned in the extended groove by applying force again, if the synthetic resin tube 10 is separated with only the clamp unit 30 removed, the auxiliary coupling nut 664 Since it becomes interpolated in the expansion groove, it is possible to space the space between the synthetic resin tubes 10 by the depth of the expansion groove.

At this time, by implementing the configuration according to the above [Table 1] to both of the two auxiliary coupling flange portion 613 penetrating through both ends of the auxiliary coupling bolt 661, it has the advantage that can be widened to have more spacing. .

On the other hand, in order for the auxiliary coupling bolt 661 and the auxiliary coupling nut 664 to be coupled upward or downward, the operating groove may be further configured in the lateral direction of the extended extension groove as shown in [Table 1]. .

In Table 1, the manipulation groove is shown to be formed only in one direction, but may be formed in both directions.

The operation portion is interpolated and coupled to the operation groove. The operation unit is configured such that the shaft protrudes to the upper and lower surfaces, and is fixedly coupled to the operation groove using the shaft.

That is, an axial groove into which the shaft of the operation unit can be inserted may be formed in the operation groove.

In addition, the operation unit has a surface in contact with a concave surface of the operation groove having an inclined surface inclined in an extended extension groove direction.

In addition, according to one embodiment, by applying a torsion spring to the axis of the operating portion, it is possible to return to the original position again after being pressed by the inclined surface by applying the force to the operating portion.

In addition, a concave groove having a predetermined size is formed on a long cross-section opposite to the extended extension groove of the operation unit, and a step groove formed by concave inward on a side in the long direction of the side of the concave groove Can be formed.

A separate ring or a person's hand is inserted into the walk groove to function. Accordingly, it is possible to apply a force in the direction of the inclined surface to press the operation portion.

As described above, as the end portion in the direction of the extended extension groove of the operation unit can be pressed, the auxiliary coupling nut 664 coupled to the aforementioned auxiliary coupling bolt 661 can be moved in the direction of the extended groove.
