7. The automatic tester for optical splitters of claim 6, wherein: the top fixedly connected with spacing fixing device (6) of movable plate (21), spacing fixing device (6) are including splint (61), the inner wall fixedly connected with elastic sheet (62) of splint (61), one side fixedly connected with sloping block (63) that elastic sheet (62) kept away from splint (61).
8. The automatic tester for optical splitters of claim 7, wherein: the bottom of the clamping plate (61) is fixedly connected with the top of the movable plate (21), and the surface of the inclined block (63) is in sliding connection with the inner wall of the clamping plate (61).
9. The test method of the automatic tester for optical splitters according to any one of claims 1 to 8, characterized in that: the method comprises the following steps:
step one: opening the top cover (10) to place the optical splitter on the movable plate (21), closing the top cover (10), starting the refrigerator (7) and continuously introducing cool air at minus forty degrees centigrade into the workbench (1), so that the temperature of minus forty degrees centigrade is continuously maintained in the workbench (1) for twelve hours;
step two: after twelve hours, the motor I (12) is started and drives the threaded rod (13) to rotate, the threaded rod (13) can drive the limited moving plate (21) to move upwards, the moving plate (21) can drive the optical divider to move upwards and push the baffle plate (11) on the top cover (10) to rotate and enable the optical divider to be exposed out of the top cover (10), at the moment, the electric push rod (8) is started and pushes the push plate (9) to move, and the push plate (9) can push the exposed optical divider to move so that the optical divider moves and is clung to the limiting plate (22);
step three: the motor II (15) is started, the bidirectional screw rod (16) is driven to rotate through rotation, and the bidirectional screw rod (16) drives the two optical universal meters (17) to gather through the connecting plate, so that the two optical universal meters (17) are inserted into the input end and the output end of the optical branching device for testing;
step four: a fan group (19) in a filter box (18) below the optical divider is started to pump out cold air in the workbench (1) and blow the cold air to the optical divider through a pipeline (20).
