The application method of the ophthalmic crystalline lens clamping device of the double working modes includes the following steps：
Step 1, ophthalmic crystalline lens is clamped at a slow speed：
Under normality, it is corresponding that transmission plug (21a) is plugged in the component (4) that is spirally connected of the downlink in the middle part of major diameter cylinder (11)
In second male-pipe (41)；
Hand pinch the cylinder turn one's head (21d) rotate the rectangle inserted link (21)；
Rectangle inserted link (21) first male-pipe of rotate driving (31) rotates, described in the first male-pipe (31) driving
First riffled tube (32), uplink clamping plate (54) uplink；
Corresponding second male-pipe (41) rotation of transmission plug (21a) rotate driving, second male-pipe (41)
Corresponding second riffled tube (42), lower actuating arm (53) downlink are driven, the lower actuating arm (53) drives downlink clamping plate (51b)
Overcome the elastic force downlink of the second pressure spring (51f)；
The uplink clamping plate (54), downlink clamping plate (51b) clamp ophthalmic crystalline lens, then take out out of installation vessel；
Step 2, switching downlink is spirally connected component (4)：
It rotates the driving nut (22) and drives the driven plug (23a), driven lantern ring (23) uplink；
The driven lantern ring (23) drives spring baffle ring (21b), rectangle inserted link (21), transmission plug (21a) uplink；
Transmission plug (21a) is plugged in the downlink above major diameter cylinder (11) and is spirally connected outside component (4) corresponding second
In screwed pipe (41)；
Step 3, fast clamp ophthalmic crystalline lens：
Hand pinch the cylinder turn one's head (21d) rotate the rectangle inserted link (21)；
Rectangle inserted link (21) first male-pipe of rotate driving (31) rotates, described in the first male-pipe (31) driving
First riffled tube (32), uplink clamping plate (54) uplink；
Corresponding the two the second male-pipes (41) rotation of transmission plug (21a) rotate driving, second male-pipe
(41) corresponding second riffled tube (42), upper actuating arm (52) downlink are driven, the upper actuating arm (52) drives cannulated sleeve
(51a), downlink clamping plate (51b) overcome the elastic force downlink of the second pressure spring (51f)；
The screw pitch of the second male-pipe (41) above major diameter cylinder (11) is greater than and is located in the middle part of major diameter cylinder (11)
The second male-pipe (41) screw pitch, therefore with same rotational speed rotation cylinder turn one's head (21d) under the premise of, in step 3 under
Row clamping plate (51b) faster, therefore can faster clamp ophthalmic crystalline lens relative to downstream rate in step 1, then
It is taken out out of installation vessel.
2. a kind of application method of the ophthalmic crystalline lens clamping device of double working modes according to claim 1, special
Sign is：Downlink clamping plate (51b) lower end surface, uplink clamping plate (54) upper surface are respectively equipped with contact made of soft material.
