[0022] Please see Figures 1-5 The present invention provides the following two preferred embodiments:

[0023] Example 1: A simple metal tool holder for a CNC machine tool, comprising: a metal tool holder body 1, wherein a tool clamping position 2 is provided on the metal tool holder body 1, a tool body 3 is placed in the tool clamping position 2, and a clamping groove 4 is provided at the tool shank of the tool body 3; spring compression protrusions 5, which are symmetrically arranged on both sides of the tool clamping position 2, and the output end of the spring compression protrusions 5 contacts and limits the tool body 3; a placement component and an auxiliary component are provided in the tool clamping position 2; a U-shaped mounting groove 6 in the placement component is opened in the side wall of the tool clamping position 2, a mounting plate 7 is U-shaped and movably disposed in the U-shaped mounting groove 6, and a protrusion 8 is fixedly provided on the inner side wall of the mounting plate 7; and a protrusion 8 is provided on the side wall of the mounting plate 7. Square holes 9 are equidistantly provided. The protective rubber pad 10 has a U-shaped cross-section and wraps around the mounting plate 7 and the protrusion 8. The protective rubber pad 10 is engaged with the slot 4. Insertion holes 11 are symmetrically provided at equal intervals on both sides of the protective rubber pad 10. The upper pressure plate 12 and the lower pressure plate 13 are U-shaped and L-shaped in cross-section. The side walls of the upper pressure plate 12 and the lower pressure plate 13 are engaged. The upper pressure plate 12 and the lower pressure plate 13 are engaged with the protective rubber pad 10 and the mounting plate 7. The upper pressure plate 12 and the lower pressure plate 13 are inserted into the U-shaped mounting slot 6. Insertion blocks 14 are fixedly provided at equal intervals on the side walls of the upper pressure plate 12 and the lower pressure plate 13. The insertion blocks 14 are inserted into the square holes 9 and the insertion holes 11.

[0024] In use, the mounting plate 7 and the protruding strip 8 are snapped into the groove of the protective rubber pad 10 so that the protective rubber pad 10 covers the mounting plate 7 and the protruding strip 8. Then, the upper pressure plate 12 and the lower pressure plate 13 are installed so that the inserts 14 of the upper pressure plate 12 and the lower pressure plate 13 are inserted into the corresponding square holes 9 until the side walls of the upper pressure plate 12 and the lower pressure plate 13 are snapped together. At this time, the upper pressure plate 12 and the lower pressure plate 13 are snapped together with the protective rubber pad 10 and the mounting plate 7, ensuring that the protective rubber pad 10 is stably set on the protruding strip 8. Then, the upper pressure plate 12 and the lower pressure plate 13 are inserted into the U-shaped mounting groove. After step 6, the limiting position is completed, so that the protrusion 8 and the protective rubber pad 10 are installed in the tool holder position 2. The tool body 3 is moved to the end of the tool holder position 2 and placed there. The protrusion 8 is located in the slot 4 and works with the spring to compress the protrusion 5 to contact and limit the tool body 3. This allows the tool body 3 of the CNC machine tool to be placed in the simple metal tool holder body 1. The protective rubber pad 10 can be easily disassembled and replaced after wear. The protective rubber pad 10 set on the outer wall of the protrusion 8 is in contact with the slot 4 to prevent the tool body 3 from being damaged by collision with the protrusion 8 when it is placed, thus extending the service life of the tool body 3.

[0025] Example 2: Based on Example 1, the baffle 15 in the auxiliary component is symmetrically rotated and disposed on the side wall of the metal knife clamp body 1.

The side wall of the baffle 15 is provided with a positioning hole 16, and the threaded groove 17 is symmetrically provided on the side wall of the metal knife clamp body 1. The screw passes through the positioning hole 16 and is threadedly connected to the threaded groove 17.

[0026] In use, after the upper pressure plate 12 and lower pressure plate 13 are engaged with the protective rubber pad 10 and the mounting plate 7, rotate the baffle 15 to expose the U-shaped mounting groove 6. Insert the upper pressure plate 12 and lower pressure plate 13 into the U-shaped mounting groove 6 and then rotate the baffle 15 so that the baffle 15 is engaged with the mounting plate 7, the upper pressure plate 12 and the lower pressure plate 13. The screw passes through the positioning hole 16 and is threadedly connected to the threaded groove 17 to fix the position of the baffle 15. The operation is simple and ensures that the protrusion 8 and the protective rubber pad 10 are stably installed in the tool holder 2, which is convenient for the placement of the tool body 3.
