Four standard internal hexagonal screws pass through the screw through hole 1202 from the back and are screwed into the threaded hole 1304 to fix the cylinder 13 and the fixed block 12 together.The flat hole 1501 of the connecting shaft 15 is sleeved into the movable shaft 1302, the other end is inserted into the through hole 1203, and is inserted into the installation blind hole 1001. A standard internal hexagonal screw is sequentially inserted into the screw installation hole 1005 at the bottom of the moving block 10, the through hole 1502 of the connecting shaft 15, and the threaded hole 1303 of the air cylinder 13, thereby connecting the movable shaft 1302 of the air cylinder 13 and the moving block 10 together, enabling the up-down movement of the movable shaft 1302 of the air cylinder 13 to drive the moving block 10, the needle plate 8, and finally the probe 7 to move up and down. The positioning hole 1204 on the back of the fixed block 12 is sleeved on the two guide shafts 6, and two standard internal hexagonal screws are inserted into the threaded holes 601 of the guide shafts 6 through the screw through holes 1201, thereby fixing the fixed block 12 and the guide shafts 6 together. The limiting shaft 19 is provided with a threaded shaft 1901 and a limiting surface 1902. The threaded shaft 1901 is screwed into the threaded hole 103 to an appropriate depth (the depth can be adjusted). The threaded ends of the two speed regulating joints 14 are screwed into the air inlet 1301 of the air cylinder 13, and the other ends are respectively connected to the A and B gas outlets of the mechanical valve 16 through air pipes. The P end of the mechanical valve 16 is connected to the gas source, and the S end and the R end are connected to the silencer.

[0072] The following is the working method of the device:

[0073] First step: align the two positioning holes 2103 of the to-be-tested optical device 21 with the two positioning pins 2402, and place the soft plate 2105 on the flow guide surface 2403. Then, the flange plate 2101 is clamped into the flange lower clamping groove 2305, and the optical port gland 20 is covered. The to-be-tested optical device 21 is clamped tightly by the device lower clamping groove 2306 and the device upper clamping groove 2004.

[0074] Second step: press the mechanical valve 16 button 1603, the movable shaft 1302 of the air cylinder 13 goes down and is locked, driving the moving block 10, the needle plate 8, and finally the probe 7 to go down and be locked. During the downward movement of the probe 7, the probe 7 and the pad first contact (the middle six probes 7 contact the main pad 2104, the two probes 7 on the sides contact the flow guide surface 2403, indirectly supplying power to the side pad 2103). Then the soft plate pressing table 805 presses the soft plate 2105, making the power supply process more stable and reliable.

[0075] Third step: test the to-be-tested optical device 21.

[0076] Fourth step: after the test is completed, rotate the mechanical valve 16 button 1603 counterclockwise, and the movable shaft of the air cylinder 13 goes up and resets. The probe 7 leaves the side pad 2103 and the main pad 2104 of the to-be-tested optical device 21.

[0077] Fifth step: take out the to-be-tested optical device 21 that has completed the test.

[0078] Repeat steps one to five to test the next to-be-tested optical device 21.

[0079] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
