[0026] It should be noted that when the first telescopic member 3 of the utility model is extended, the spacing of the clamping arm members can gradually increase with the rotation of the connecting member 9. At this time, it is suitable for clamping tools 10 with larger diameters. When the first telescopic member 3 is retracted, the spacing of the clamping arm members can gradually decrease with the rotation of the connecting member 9. At this time, it is suitable for clamping tools 10 with smaller diameters. Compared with the prior art in which the spacing of the clamping blocks cannot be changed and can only adapt to the clamping of tools 10 of a single or specific size, its versatility is greatly improved.

[0027] Specifically, the spark machine also includes a second telescopic part 4, and the fixed plate assembly includes a first fixed plate 1 and a second fixed plate 2, the first fixed plate 1 connects the spark machine body and the fixed end of the second telescopic part 4, and the second fixed plate 2 connects the fixed end of the first telescopic part 3 and the telescopic end of the second telescopic part 4.

[0028] Specifically, the spark machine body also includes a pneumatic chuck, a driver and a linear module. The pneumatic chuck is connected to the linear module and clamps the tool 10. The driver drives the pneumatic chuck to move on the linear module.

[0029] The second telescopic member 4 of the utility model can adjust the position of the second fixed plate 2. When the tool 10 needs to be replaced, the driver first drives the pneumatic chuck to face the clamping claw assembly of the second fixed plate 2 that does not clamp the tool 10, and then extends the first telescopic member 3 and opens the clamping arm member. After the driver drives the pneumatic chuck to clamp the tool 10 in the clamping space of the clamping arm member, the first telescopic member 3 is retracted. After the clamping arm member clamps the tool 10, the pneumatic chuck releases the tool 10, and then starts the second telescopic member 4. The telescopic spacing of the second telescopic member 4 each time is consistent with the spacing between the center points of adjacent tools 10. When the required tool 10 moves to face the pneumatic chuck, the second telescopic member 4 is closed, the pneumatic chuck clamps the tool 10, and the first telescopic member 3 is extended to release the tool 10. Of course, it should be noted that in order to flexibly adjust the position of the pneumatic chuck, the utility model comprises an X-axis guide, a Y-axis guide and a Z-axis guide, there is a first connecting block between the X-axis guide and the Y-axis guide, there is a second connecting block between the Y-axis guide and the Z-axis guide, there is a third connecting block between the Z-axis guide and the pneumatic chuck, and the driver is a motor, which is connected to the first connecting block, the second connecting block and the third connecting block.

The first end of the connecting arm 6 is rotatably connected to the limiting plate 5, and the second end of the connecting arm 6 is fixedly connected to the clamping plate 7.

[0031] Specifically, the clamping jaw assembly further includes a connecting rod 8 , which is rotatably connected to the first end of the connecting member 9 and fixedly connected to the telescopic end of the first telescopic member 3 .
