Multi-purpose flexible turning tool of lathe

The utility model discloses a multi-purpose flexible turning tool of a lathe, which is provided for overcoming the defects of low work efficiency and product qualified rate, high production cost, and influence on enterprise economic benefit caused by serious loss of the existing rigid turning tool using a welded hard alloy tool bit due to large turning force during the using process. The front end of a tool bar is connected with a tool chuck for clamping the tool bit, and the tool bar is flexibly connected with the tool chuck. As the tool bar and the tool chuck which form the turning tool are in flexible connection, when the tool bit is subjected to larger turning resistance, the tool chuck for mounting the tool bit can flexibly contract so as to reduce the cutting depth, thus protecting the tool bit from being damaged; simultaneously, an unsharp spare tool bit on the tool chuck can be replaced at any time, thus greatly improving the work efficiency, ensuring the processing quality, saving the production cost
