The fastening fasteners 310 and horizontally operated fasteners 320 which are respectively inserted into and disposed on opposite surfaces of the unit frame 220 of the unit 200 are configured. At this time, the locking fastener 310 and the horizontal operation fastener 320 is disposed in a form that is inserted inside so as not to protrude from the side of the unit frame 220, respectively.

The locking fastener 310 and the horizontal operating fastener 320 are engaged with the horizontal fastening fastener 320 and the fastening fastener 310 as the horizontal operating fastener 320 rotates. A traction force for 310 is generated, and the unit frames 220 adjacent to each other in the horizontal direction are configured to be tightly coupled by the traction force of this horizontal actuation fastener 320.

Looking in more detail, the locking fastener 310 is configured to include a locking case 311 is inserted and coupled to one side of the unit frame 220, and a locking bar 312 mounted inside the locking case 211 do.

Horizontal operation fastener 320 is a horizontal operation case 321 is inserted into and coupled to the other side of the unit frame 220, the horizontal operation case 321 is rotatably coupled to the inside of the wrench insertion hole 323 in the center The horizontal operating shaft 322 is formed, a circular horizontal rotating plate 324 eccentrically coupled to the horizontal operating shaft 322 to rotate integrally with the horizontal operating shaft 322, and a through hole 327 is formed on one side The outer circumferential surface of the circular horizontal rotating plate 324 is in close contact with the inner circumferential surface of the through hole 327 and is coupled to the circular horizontal rotating plate 324 in the form of being inserted in close contact with the other side. 326 comprises an actuating ring 325 formed.
