Fitment tool of disconnecting link quick mechanism and fitment method thereof

The invention relates to a fitment tool of a disconnecting link quick mechanism and a fitment method thereof. A connecting rod base (1A) is formed on one end of a fitment connecting rod (1), and a pin roll groove (3) and a pin roll (6A) for carrying the bottom end of a compressed spring assembly (6) are formed on the connecting rod base. A fitment connecting rod sleeve (2) is sleeved on the fitment connecting rod (1) in a penetrating mode, and a buckle piece (5) is formed at the side of the upper end of the fitment connecting rod sleeve. The buckle piece can be freely and detachably buckled on a nylon head (7) for fixing at the upper end of the compressed spring assembly (6) of a grounding disconnecting link of the disconnecting link quick mechanism, and a compressed spring (9) is pressed through the nylon head. A thread section and a clamp nut (4) which is screwed with the thread section and is used for blocking the fitment connecting rod sleeve and the buckle piece and applying pressure are formed on the up
