The conductive sheet and the magnet are matched to ensure the motion state of the sliding block 371 in the first spiral groove 322 and the second spiral groove, and meanwhile, the transient state that the connecting piece cannot drive the reversing shaft 370 to move due to the temporary separation of the first rack 380 and the gear at the lower end of the first gear 230 when the first rack 380 rotates along with the fifth gear 360 can be avoided, and the movement of the reversing shaft 370 is ensured.
With the combination of the above embodiments, the specific working principle and working process of the present invention are as follows: before polishing, an ophthalmic surgical instrument is clamped in the first clamping part, the top block 390 of the first clamping part in an initial state is arranged downwards, so that the two clamping plates 340 of the first clamping part are in a clamping state, and the top block 390 of the second clamping part is arranged upwards, so that the two clamping plates 340 of the clamping part are in a loose state.

And in the process of clockwise rotation of the reversing shaft 370, the fourth gear 310 fixedly mounted on the reversing shaft 370 is synchronously driven to rotate 180 °, further the fifth gear 360 is driven to rotate 180 ° counterclockwise, the first rack 380 is eccentrically arranged on the fifth gear 360, and the first rack 380 rotates 180 ° with the fifth gear 360, so that the first rack 380 rotates to a position close to the polishing disk 220 relative to the first gear 230, as shown in fig. 10, that is, the tooth part of the first rack 380 is arranged opposite to the tooth part of the second rack 381.
The motor 210 rotates continuously in one direction, and drives the first gear 230 and the second gear 240 through the third gear 250, and further drives the first rack 380 and the second rack 381 to move away from each other, when the first rack 380 and the second rack 381 move away from each other, the sliding block 371 of the reversing shaft 370 moves from the second straight slot to the reversing cylinder 320 under the restriction of the first one-way block 323, so that the reversing shafts 370 of the first clamping portion and the second clamping portion move away from each other, and in the process of moving away the first rack 380 and the second rack 381 from each other, the polishing disc 220 polishes the other end of the front surface of the ophthalmic surgical instrument (i.e., the portion initially clamped by the first clamping portion).
In the process that the first rack 380 and the second rack 381 are far away from each other, the sliding block 371 of the reversing shaft 370 comes to the starting end of the second spiral groove, and meanwhile when the sliding block 371 slides to the position of the second spiral groove, the sliding block 371 is again contacted with the conducting strip to electrify the electromagnet 324 close to one end of the second spiral groove, so that the electromagnet 324 attracts the sliding block 371 to move in the second spiral groove, the sliding block 371 can rotate anticlockwise in the form of a spiral in the second spiral groove, and then the reversing shaft 370 is driven to move while rotating anticlockwise, that is, after the sliding block 371 slides to the terminal end of the second spiral groove at the starting end of the second spiral groove, the sliding block 371 drives the reversing shaft 370 to rotate anticlockwise by 180 degrees in the axial direction.
And the holder 350 connected with the reversing shaft 370 through the one-way bearing rotates during the counterclockwise rotation of the reversing shaft 370.

The motor 210 rotates in one direction, and the rotation of the motor 210 causes the first rack 380 and the second rack 381 to approach each other again, and the polishing plate 220 polishes one end of the opposite surface of the ophthalmic surgical instrument (i.e., the portion not held by the second holding portion) while the first rack 380 and the second rack 381 approach each other, in the same manner as described above. The slider 371 of the reversing shaft 370 moves in the first straight groove 321 into the first spiral groove 322, and the electromagnet 324 near one end of the first spiral groove 322 is turned on again to reverse the reversing shaft 370, and after reversing 180 degrees again, the downward top block 390 is turned to the upward position, the upward top block 390 is turned to the downward position, the first clamping portion is in the clamped state, and the second clamping portion is in the relaxed state.

In the process that the motor 210 continues to rotate, the motor 210 drives the first rack 380 and the second rack 381 to be away from each other, when the first rack 380 and the second rack 381 are away from each other, the sliding block 371 of the reversing shaft 370 moves from the second straight groove into the reversing cylinder 320 under the limitation of the first one-way block 323, so that the reversing shafts 370 of the first clamping portion and the second clamping portion are away from each other, and in the process that the first rack 380 and the second rack 381 are away from each other, the polishing disc 220 polishes the other end (i.e., the portion clamped by the second clamping portion) of the reverse side of the ophthalmic surgical instrument, and then the whole polishing process of the ophthalmic surgical instrument is finished, and the ophthalmic surgical instrument is taken down for polishing next time. Above-mentioned process falls into four parts with ophthalmic surgery apparatus and polishes respectively (the one end of front centre gripping, the one end of reverse side centre gripping not, the one end of reverse side centre gripping), guarantees that burnishing device can polish to the part of centre gripping in step when polishing, has realized the comprehensive polishing to ophthalmic surgery apparatus, and in whole polishing process, hydrojet mechanism 400 is through hydrojet pipe 410 blowout coolant liquid, clears up the piece after the polishing, cools down polishing dish 220 simultaneously.
