The tool is an important part of CNC and is a tool for cutting processing. In addition to the cutting blade, the "CNC tool" also includes accessories such as tool rods and tool holders. When the tool moves during use, the tool running diameter and the tool standard diameter caused by various reasons such as the machine tool spindle or the tool will deviate, that is, the tool swing phenomenon. Therefore, in order to ensure the accuracy of CNC processing, the tool needs to be detected using a tool swing meter before use.

When in use, the telescopic frame 201 is telescoped to change the spacing between adjacent mounting pins 202, thereby adjusting the spacing between adjacent first placement plates 301, so as to facilitate the taking and storage of the tools inside the placement slot 307. When not in use, the adjacent first placement plates 301 are stacked together, and the first placement plate 301 is covered on the top of the second placement plate 305 to reduce the occupied space.

When storing or taking out a tool, when the tool is placed in the placement slot 307, the bottom of the tool contacts the touch switch 310 so that the touch switch 310 controls the indicator light 308 to emit green light, indicating that a tool is placed in the corresponding placement slot 307. After the placement is completed, the servo motor 209 is started in reverse to shrink the telescopic frame 201, so that the first placement plate 301 and the top cover 303 move downward, so that the top cover 303 clamps the sealing groove 306 on the top of the topmost first placement plate 301, and at the same time, the sealing plate 304 clamps the sealing groove 306 on the bottom first placement plate 301 to prevent dust from falling on the tool on the placement slot 307.
