[0038] The connecting member 1 7 includes two magnetic members 1 which are respectively arranged inside the fixing groove 25 and the fixing groove 1 101 and attract each other.

[0039] Preferably, the support seat 4 comprises a support frame 401 with a hollow interior, and detection ports 402 provided on the front and rear side walls of the support frame 401;

[0040] The support portion 21 is placed in the cavity inside the support frame 401 , and the detection port 402 corresponds to the calcium fluoride window.

[0042] The connecting member 2 8 includes two magnetic members 2 which are respectively arranged inside the fixing groove 3 26 and the fixing groove 4 403 and attract each other.

[0043] Preferably, the second magnetic attraction member on the support portion 21 is disposed on the periphery of the first clamping groove 23 , and the second magnetic attraction member on the support frame 401 is disposed on the periphery of the detection port 402 .

[0044] When in use, the mechanical arm clamps the clamping part 22, clamps the clamping part 22 and the supporting part 21 and places them horizontally on the top of the supporting frame 1, fixes the supporting part 21 on the top of the supporting frame 1 through the connecting piece 1 7, clamps the calcium fluoride window substrate 5 and places it inside the clamping groove 1 23, presses the calcium fluoride window substrate 5 downward, and the clamping ring gasket 6 is clamped into the inside of the clamping groove 2 501.
