The invention discloses a lathe tool frame capable of quickly disassembling and positioning a lathe tool. The lathe tool frame comprises a lathe tool frame body for clamping the lathe tool frame, a press plate, a support frame, a gear shaft, and a rocking handle for driving the gear shaft to rotate by worm-gears, wherein the press plate is arranged on the lathe tool frame body in a sliding way, the gear shaft is rotatablely supported on the support frame, a great is sleeved on the gear shaft, a rack part matched with the gear is arranged on the press plate, and the rack is meshed with the gear. According to the lathe tool frame, unnecessary time waste in the process of manufacture can be effectively reduced, the machining precision of a lathe machining system can be observably improved, and the machining efficiency can be improved.
