Method for quickly establishing segmented tongue-and-groove fence

The invention discloses a method for quickly establishing a segmented tongue-and-groove fence. The method comprises the following steps that a target sleeve penetrating through a clamping bolt is determined according to the type of a segmented groove and tongue; a fixture sleeves the target sleeve, and a clamping screw penetrates through the target sleeve; a bottom column closely fits a free edgeof the segmented groove and tongue, the clamping screw is vertically adjusted so that a clamping plate cooperates with the bottom column to clamp the segmented groove and tongue, and then the fixtureis closed to lock and fix the clamping screw; a plurality of sets of arm stumps are arranged at the free edge of the segmented groove and tongue, and a rope runs through rope clamping grooves of handrails to form the segmented tongue-and-groove fence. The method for quickly establishing the segmented tongue-and-groove fence is suitable for segmented grooves and tongues of different types, has highflexibility, can quickly c
