[0022] The fixing mechanism includes several springs 3, each fixed to the inner wall of the tool holder 1. Each spring 3 has a steel ball 31 at its end. A limit block 32 is connected to one side of each steel ball 31. A movable tube 33, which is telescopically connected to the tool holder 1, is fixed to the right side of the limit block 32. A pressing member 34 is fixed to the end of the movable tube 33. Several wear-resistant grooves 35, matching the steel balls 31, are formed on the outer surface of the fixing rod 2. An auxiliary mechanism for further fixing the tool is fixed to one end of the pressing member 34. By manually pressing the pressing member 34, the movable tube 33 is moved. This causes the limiting block 32 to push the steel ball 31 to move horizontally, causing the steel ball 31 to separate from the through hole on the inner wall of the tool holder 1. At this time, the steel ball 31 separates from the wear-resistant groove 35 on the fixing rod 2, thereby releasing the fixing rod 2 and allowing it to be disassembled. When the steel ball 31 moves, it will push the spring 3 to compress. After the fixing rod 2 is replaced, the pressing part 34 is manually released. During the extension of the spring 3 itself, the steel ball 31 is pushed to reset, so that the steel ball 31 and the outer surface of the wear-resistant groove 35 come into contact, thereby squeezing and fixing the fixing rod 2. The wear-resistant groove 35 also plays an anti-slip role, thereby reducing the possibility of falling off. Example 2
