The third limiting stopper 35 can limit the manipulator, so that the manipulator is prevented from slipping during clamping, and the manipulator is more convenient to clamp and operate. The third limit stop 35 is a circular stop disposed at the top of the second post 34 in this embodiment. The second post 34 is a square post having a rectangular cross-section. Specifically, four second clamping planes 341 are disposed on the circumferential side wall of the second cylinder 34, and two of the four second clamping planes 341 are parallel to each other. The second clamping plane 341 is more convenient for the robot to clamp.

It should be noted that, in the process of opening or closing the transition container, the transition container is placed in the center of the hot chamber, and two manipulators are required to operate together, one manipulator is used for operating a switch tool, and the other manipulator is used for fixing an auxiliary fixing structure. Therefore, the second clamping plane 341 of the second column 34 forms an angle with the center line of the second base 32, which further facilitates the clamping of the robot.
