Accordingly, if necessary, the coupling 100 can be fixed with the fixing bar 51 at four locations at a 90 degree angle. Therefore, even the heavy coupling 100 can be firmly fixed to the work board 60 and placed in a horizontal state.

Each long hole 61 may have a structure that extends long toward the center of the work plate 60. Accordingly, the fixing position for the coupling 100 can be changed by moving the fixing bar 51 along the long hole 61. The coupling 100 can be fixed by moving the fixing bar 51 within the long hole 61 according to the diameter of the coupling 100. Therefore, it is possible to perform assembly work by fixing various couplings 100 regardless of the size of the coupling 100.
