[0039] Specifically, the optical platform 1 adopts a vibration-isolating honeycomb optical platform. The optical platform 1 is horizontally arranged on a fixed bracket 8. A support frame 2 of a frame structure is arranged on the table of the optical platform 1. A top cover 3 is horizontally arranged on the top of the support frame 2. The top of the top cover 3 is covered with a first light-shielding curtain 4. One side of the second light-shielding curtain 5 is slidably connected to the edge of the top cover 3 through a plurality of hooks. The hooks can slide along the edge of the top cover 3, so that the second light-shielding curtain 5 can be pulled like a curtain and the second light-shielding curtain 5 surrounds the support frame 2 and forms a light-shielding cover together with the first light-shielding curtain 4, providing a dark environment for the experimental device located on the optical platform 1 inside. At the same time, when a dark experimental environment is not needed, it is only necessary to fold up the second light-shielding curtain 5 like a curtain and fold up the first light-shielding curtain 4, which is convenient and quick.

[0040] Specifically, the edge of the first shading curtain 4 hangs down freely to form a skirt surrounding the top cover 3, and the skirt is located on the outside of the second shading curtain 5, so that the connection position between the second shading curtain 5 and the top cover 3 can be better shielded to avoid light leakage; at the same time, the bottom edge of the second shading curtain 5 should hang down to the ground or on the platform used to place the device, so as to ensure that the device can provide a dark experimental environment.

[0044] Reference Figure 6 and Figure 7 As shown, further, the adapter 6 is connected to the optical platform 1, and a slot 61 perpendicular to the optical platform 1 is provided on the adapter 6, the shape of the slot 61 corresponds to the shape of the column 21, and a fastening hole 62 connected to the slot 61 is provided on the adapter 6, and one end of the column 21 is inserted into the slot 61 and connected to the adapter 6 at the fastening hole 62 by a bolt. Specifically, the adapter 6 can be connected to the optical platform 1 by bolts, which is convenient for installation and disassembly.

[0045] Furthermore, it also includes a positioning member 7, which is sleeved on the column 21, and has two mutually perpendicular positioning holes 71 on the positioning member 7, the shape of the positioning hole 71 corresponds to the shape of the cross bar 22, and the positioning member 7 is provided with a plurality of fixing holes 72 connected with the positioning holes 71, and the end of the cross bar 22 is inserted into the positioning hole 71 and connected with the positioning member 7 at the fixing hole 72 by bolts.
