A separately manufactured jig device for connecting a duct is provided to easily control the height of a fixed duct with fixing the duct regardless of the shape of the duct by using an elastic strip made of a rubber material. A separately manufactured jig device for connecting a duct includes a magnetic block(1). The magnetic block generates a magnetic force according to switch control to keep a fixing force to a still flat plate. A support column(2) is fixed on the magnetic block and has a certain height. A moving column(3) surrounds the support column and changes its location on the support column. A vertical height control bolt(4) fixes the changed location of the moving column on the support column. An elastic strip(7) is located on a lower part of one surface of the moving column and winds around a duct. One end of the elastic strip is fixed on a lower supporting part(6). An elastic strip fixing part(5) is located on an upper part of one surface of the moving column and fixes a free end of the elastic strip. |
