The apparatus as claimed in claim 2, wherein a plurality of first abutment stages are provided at intervals on a side of the support frame facing the support frame, a plurality of second abutment stages are provided at intervals on a side of the support frame facing the support frame, and the first abutment stages and the second abutment stages are in the same number and abut against each other in a one-to-one correspondence;
and/or the presence of a gas in the gas,
one side of the supporting bottom frame, which is deviated from the opening, is abutted against the hole wall of the mounting hole.
6. The lenticular support apparatus of any one of claims 1 to 5, wherein the flexible stage has a support surface for supporting the lenticular, and at least one side surface of the flexible stage connected to the support surface is concavely formed with a first buffer groove;
and/or the presence of a gas in the atmosphere,
the flexible pressing block comprises two flexible surfaces which are correspondingly arranged, any one of the flexible surfaces is used for being abutted to the cylindrical lens, and at least one of the flexible surfaces is concave to form a second buffer groove.
7. The lenticular support apparatus of any one of claims 1 to 5, wherein a portion of the wall of the mounting hole is recessed to form an escape groove for escaping the flexible stage.
8. The lenticular support apparatus of any one of claims 1 to 5, wherein the mounting hole has a plurality of protrusions protruding at intervals, each of the plurality of protrusions being adapted to abut against a side wall of the lenticular.
9. The lenticular support apparatus of claim 8, wherein the number of the projections corresponds to the number of the support tables and is arranged in one-to-one correspondence.
