The electronic tag 150 is inserted into the tag insertion groove 161 formed in the upper connection part 162 of the connection part 160.

The fixing pin 180 is coupled to the fixing pin coupling groove 164 formed in the lower connecting portion 165 of the connection unit 160. In the embodiment of the present invention, the fixing pin coupling groove 164 and the fixing pin 180 are configured to be mutually combined.

The bottom surface of the lower core 121 of the first core 120 is directly screen-printed or, if necessary, a second core printed with the buried material information is attached. The first core 120 is made of a transparent polycarbonate material, the buried material information is transmitted upward.

The first hermetic means 140 is formed on an upper surface of the lower core 121 of the first core 120, that is, an annular surface provided by a step with the lower core 121 having a diameter larger than that of the upper core 122. To seat.

As described above, the first core 120 in the state in which the first hermetic means 140 is coupled is interposed upwardly from the lower first hole 111 of the cover part 110 toward the upper second hole 113.

The upper core 122 of the first core 120 is inscribed in the second hole 113 of the cover part 110, and the lower core 121 of the first core 120 is inscribed in the first hole 111. The first hermetic means 140 is inscribed. Since the position of the lower core 121 is restricted by the step between the first hole 111 and the second hole 113, the first core 120 is restricted from entering and exiting the upper side of the second hole 113.

As described above, in the state in which the first hermetic means 140 and the first core 120 are embedded inside the cover part 110, the connection part in which the electronic tag 150 and the fixing pin 180 are coupled as described above. Join 160.
