[0019] The structure of a tool fixing mechanism for a numerical control machine tool provided by the present invention is as Figure 1 and Figure 2 shown, including a tool holder 1. A tool loading groove 2 is opened inside the tool holder 1, and this tool loading groove 2 is used for the insertion and installation of the tool; two quick-installation structures 3 are installed at the top of the tool holder 1, and this quick-installation structure 3 is used for the locking and fixing of the tool. The quick-installation structure 3 is composed of a pull pin 31, a placement groove 32, a tension spring 33, and a pressing piece 34. The placement groove 32 is opened inside the tool holder 1. A pull pin 31 is provided at the top of the tool holder 1, and the bottom end of the pull pin 31 passes through the placement groove 32 and extends into the tool loading groove 2 and is fixed with a pressing piece 34. This pressing piece 34 is used for pressing and fixing the tool. A tension spring 33 is sleeved on the surface of the pull pin 31 and inside the placement groove 32, and the bottom end of the tension spring 33 is fixedly connected to the surface of the placement groove 32, and the top end of the tension spring 33 is fixedly connected to the surface of the pull pin 31.

[0020] During implementation, the tool is inserted into the tool loading groove 2. After insertion, the elastic force of the tension spring 33 inside the placement groove 32 is used to pull the pull pin 31 to drive the pressing piece 34 to move downward, and the pressing piece 34 will firmly press the tool when moving.

[0021] Furthermore, as Figure 2 and Figure 3As shown in the figure, reinforcement structures 4 are provided on both the left and right sides of the tool holder 1. The reinforcement structure 4 is used to increase the reinforcement when the tool is fixed. The reinforcement structure 4 includes a mounting seat 41, a reinforcement groove 42, a reinforcement rod 43, a locking spring 44, and a reinforcement block 45. The mounting seat 41 is fixedly connected to the surface of the tool holder 1, and a reinforcement groove 42 is provided inside the mounting seat 41. The reinforcement rod 43 is provided on one side of the tool holder 1, and one end of the reinforcement rod 43 penetrates through the reinforcement groove 42 and is fixed with a reinforcement block 45.
