The bottom of the insertion piece 1311 is rectangular and the top is triangular with a gradually decreasing upward angle, so that the pin piece 3421 can be inserted easily.

When pin 3421 is inserted into gap 1312, bayonet sleeve 1310 is rotated to rotate connecting bar 3420 synchronously, and connecting bar 3420 is rotated while being lifted relative to bayonet sleeve 1310, but the distance for lifting connecting bar 3420 is limited, so that the lifting stroke of connecting bar 3420 is about 50 mm, but connecting bar 3420 is lifted to a position out of gap 1312.
