Four groups of mounting plates 9 and telescopic clamping blocks 10 are arranged in an array on the fixing plate 7. When the first flange 1 and the second flange 2 are plugged into each other, the engaging protruding ring 3 of the first flange 1 extends into the second flange 2 and abuts against the telescopic clamping block 10. Due to the pressure of the insertion, the telescopic clamping block 10 contracts toward the mounting plate 9 until the convex ridge 12 of the telescopic clamping block 10 is engaged with the groove of the engaging protruding ring 3, thereby completing the pre-fixation between the first flange 1 and the second flange 2, and then the first flange 1 and the second flange 2 are further fastened with bolts.
