[0023] See also Figure 4The utility model provides a CNC tool for machining. The transmission structure 44 includes a connecting plate 441, a straight rod 442 and a clamping structure 443. Three groups of straight rods 442 are arranged in an array with the circular groove 42 as the center of the circle, and the upper end surface of the straight rod 442 is fixedly connected to the connecting plate 441. The lower end of the left straight rod 442 passes through the fixed plate 43 and is fixedly connected to the clamping structure 443. The lower right end of the clamping structure 443 fits with the tool handle 45. The middle part of the upper end surface of the connecting plate 441 is fixedly connected to the telescopic rod 6, which is conducive to driving the connecting plate 441 to move up and down through the telescopic rod 6. The clamping structure 443 is provided with three groups in total, and is arranged in an array with the circular groove 42 as the center of the circle, and is fixedly connected to the three straight rods 442 respectively, so as to facilitate the stable clamping of the tool handle 45.

[0024] See also Figure 5 The utility model provides a CNC tool for machining. The clamping structure 443 includes a clamping plate 4431, a first connecting rod 4432, a second connecting rod 4433 and a rotating block 4434. The front and rear ends of the upper left side of the clamping plate 4431 are rotatably connected to the first connecting rod 4432 through a rotating shaft, and the upper end surface of the first connecting rod 4432 is fixedly connected to the fixed plate 43.

[0025] Here’s how it works:

[0026] First, the connector 5 of the utility model is installed on the machine, and the telescopic rod 6 in the CNC tool 3 is controlled to be telescopic through an external controller, and the tool handle 45 to be used is placed in the placement groove 2 of the rectangular plate 1;

[0027] Second, when the knife handle 45 needs to be replaced, the telescopic rod 6 is extended by controlling the external controller, and the telescopic rod 6 pushes the connecting plate 441 downward to move downward, and the connecting plate 441 drives the three straight rods 442 to move downward. Since the straight rod 442 passes through the connecting plate 441 and is fixedly connected to the clamping structure 443, the straight rod 442 drives the rotating block 4434 to move downward, and the rotating block 4434 is rotationally connected to one end of the second connecting rod 4433 through a rotating shaft, and the other end of the second connecting rod 4433 is rotationally connected to the clamping plate 4431 through a rotating shaft, so that the rotating block 4434 drives the second connecting rod 4433 to move downward, and the second connecting rod 4433 drives the clamping plate 4431 to move downward;

[0028] Third, the clamping plate 4431 is connected to the first connecting rod 4432 through the rotating shaft, so that the second connecting rod 4433 moves downward and pushes the clamping plate 4431 to rotate. The clamping plate 4431 drives the anti-sliding block 4435 to move, and the anti-sliding block 4435 moves away from the tool handle 45, so that the tool handle 45 is released from the limit, and then the tool handle 45 falls into the placement slot 2. By moving the CNC tool 3 to the new tool handle 45 that needs to be replaced, the telescopic rod 6 is controlled to shrink, so that the clamping plate 4431 drives the anti-sliding block 4435 to clamp the tool handle 45, thereby achieving the effect of facilitating the tool handle 45.
