The utility model relates to a tool holder lifting mechanism during tool changing of an umbrella-shaped tool magazine. A fixed support is installed on a tool disc, a guide pressing block is installed on the fixed support, a movable support is inserted into the guide pressing block to do sliding motion, a tool holder is installed on the movable support, a tool is installed on the tool holder, a plate is installed on an air cylinder, and the air cylinder drives the plate to do lifting motion in the vertical direction. The plate drives the movable support to do up-down lifting movement, the movable support drives the tool holder and the tool to do up-down lifting movement together, and then lifting movement of the tool holder is achieved through control of the air cylinder. And the diameter of the cutter head meets the requirement that the fixed brackets are densely arranged under the condition that the maximum cutter diameters of adjacent cutters do not interfere with each other. The numerical control machine t
