ELASTIC COUPLER HAVING LOCKING-UNLOCKING FUNCTION

摘要

An elastic coupler, according to one embodiment of the present invention, comprises: a hollow socket having an upper holding protrusion and a lower holding protrusion which are inserted into a first insertion hole and a second insertion hole which are respectively formed in a first object to be coupled and a second object to be coupled so as to couple the first object to be coupled and second object to be coupled and respectively protrude from an outer peripheral surface so as to be disposed on the upper end portion and the lower end portion of the hollow socket, and two or more guide slots which are formed on the outer peripheral surface from the lower end in a direction parallel to the direction of insertion; support pins which are inserted into the hollow socket so as to limit the movement of the upper holding protrusion and the lower holding protrusion towards the inside of the hollow socket; and fixing pins having two or more guide protrusions which protrude from the outer peripheral surfaces of the support pins and respectively move along the guide slots.
