[0022] The working principle of this embodiment:

[0023] A conveying mechanism is provided in the cleaning chamber 1. The tool is driven by the conveying mechanism to move axially along the main transmission shaft 8. Before the tool moves to the specified position, the PLC sends a command to the cylinder. The piston rod of the cylinder drives the main transmission shaft 8 to rotate through the connecting piece 6 and the crank 7. The main transmission shaft 8 drives the first blocking plate 15 to rotate, and at the same time drives the second blocking plate 19 to rotate through the connecting rod 17. The first blocking plate 15 and the second blocking plate 19 rotate 90 degrees. When the tool moves to the specified position, it is blocked by the first blocking plate 15 and the second blocking plate 19, so that the tool waits in the chamber to realize automated production. The position sensor 5 can detect the position of the cylinder piston rod, transmit the signal to the PLC, and control the rotation process of the first blocking plate 15 and the second blocking plate 19.
