The invention discloses a floorboard installing lock catch and an installing method of the floorboard installing lock catch. A conical main bar is arranged in the middle part of a lock catch main body; two groups of first convex blocks are installed; each lock catch hook is arranged between each first convex block and the conical main bar; the top of each lock catch hook is provided with a lock catch hook inclined edge used for preventing a wood plate block from vertically moving; a second reserved space being 5 to 7mm is formed between each lock catch hook and the corresponding first convex block; a first reserved space being 1 to 2mm is formed between the conical main bar and each lock catch hook; an expansion and retraction groove is formed in the center position of the upper part of the conical main bar; two groups of second convex blocks are arranged; after each second convex block is clamped by a corresponding second convex block insertion groove formed in the wood plate block, the wood plate block is downwards pressed; each lock catch hook is enabled to move in the first reserved space being 1 to 2mm between the conical main bar and each lock catch hook by the corresponding lock catch insertion groove edge of the wood plate block; and when each first convex block enters a corresponding first convex block insertion groove, each lock catch hook slides along the lock catch hook inclined edge to enter the corresponding lock catch hook insertion groove for fixation. The floorboard installing lock catch and the installing method of the floorboard installing lock catch have the advantages that a floorboard is installed in a completely and downwards extruded way; the installation of the floorboard is convenient; the replacement and the dismounting are convenient and fast; and the labor is saved.
