The user then continues to pull the annular disk 211, allowing the annular disk 211 to pull the sleeve 208 upward through the push rod 215, so that the sleeve 208 and the movable block 204 are separated. Then, after the sleeve 208 and the movable block 204 are separated, the torsion spring can control the movable block 204 to rotate outward and reset, so that the movable block 204 drives the limit block 207 to disengage from the inside of the limit groove 206. Then the user can remove the tool 3 and the engaging block 202 to complete the disassembly work, which is more convenient.

[0025] The working principle of this CNC milling machine tool holder that facilitates tool disassembly:

[0026] When in use, the user first drives the engaging block 202 to be inserted into the engaging groove 201 through the tool 3, and then the user can control the sleeve 208 to move downward, so that the sleeve 208 drives the slider 210 to move along the slide groove 209, and then when the sleeve 208 is connected with the movable block 204, the sleeve 208 will push the movable block 204 to rotate with the fixed rod 205 as the axis, so that the movable block 204 twists the torsion spring, and at the same time, the movable block 204 drives the limit block 207 to be stuck in the limit groove 206, thereby initially achieving After the installation of the engaging block 202 and the tool 3, the user pushes the annular disk 211 downward, so that the annular disk 211 pushes the moving block 212 to move downward, and then the moving block 212 pushes the push rod 215 through the inclined surface of the No. 1 guide groove 214, so that the push rod 215 drives the limiting plate 219 to squeeze the No. 1 spring 220, and at the same time, one end of the push rod 215 is stuck in the interior of the positioning groove 216 to realize the positioning of the sleeve 208, and finally the positioning frame 223 is pushed by the No. 2 spring 222. The positioning frame 223 is inserted into the interior of the positioning hole 224 to realize the positioning of the annular disk 211, so that the handle body 1 drives the tool 3 to rotate at high speed, and the sleeve 208 can stably position the tool 3. Then, when the tool 3 needs to be disassembled, the positioning frame 223 only needs to be pushed to disengage it from the interior of the positioning hole 224. Then, the user pulls the annular disk 211 upward, so that the annular disk 211 first drives the moving block 212 to move upward, and the No. 1 spring 220 pushes the push rod 215 to disengage. The user then continues to pull the annular disk 211, allowing the annular disk 211 to pull the sleeve 208 upward through the push rod 215, so that the sleeve 208 and the movable block 204 are separated. After the sleeve 208 and the movable block 204 are separated, the torsion spring can control the movable block 204 to rotate outward and reset, so that the movable block 204 drives the limit block 207 to disengage from the limit groove 206. Then the user can remove the tool 3 and the engaging block 202 to complete the disassembly work, which is more convenient.
