step 2, switching the downlink screw connection component (4):
the driving nut (22) is rotated to drive the driven plug (23 a) and the driven lantern ring (23) to move upwards;
the driven lantern ring (23) drives the spring stop ring (21 b), the rectangular inserted link (21) and the transmission plug (21 a) to move upwards;
the transmission plug (21 a) is inserted into a second external thread pipe (41) corresponding to the downward screw joint component (4) above the large-diameter cylinder (11);
step 3, rapidly clamping the ophthalmic lens:
the cylindrical twisting head (21 d) is pinched by a hand to rotate the rectangular insertion rod (21);
the rectangular inserted rod (21) rotates to drive the first external threaded pipe (31) to rotate, and the first external threaded pipe (31) drives the first internal threaded pipe (32) and the upper-going clamping plate (54) to go upwards;
the transmission plug (21 a) rotates to drive the corresponding second external threaded pipe (41) to rotate, the second external threaded pipe (41) drives the corresponding second internal threaded pipe (42) and the corresponding upper driving arm (52) to move downwards, and the upper driving arm (52) drives the hollow sleeve (51 a) and the lower clamping plate (51 b) to move downwards by overcoming the elasticity of the second pressure spring (51 f);
the thread pitch of the second externally threaded tube (41) positioned above the large-diameter cylinder (11) is larger than that of the second externally threaded tube (41) positioned in the middle of the large-diameter cylinder (11), so that on the premise of rotating the cylindrical twisting head (21 d) at the same rotating speed, the descending splint (51 b) in the step 3 is higher in descending speed relative to the descending speed in the step 1, so that the ophthalmic lens can be clamped quickly and then taken out of the container vessel;
