Detailed ways

Please refer to Figure 1-4. An eyeball fixation device includes a placement box 1. The bottom end of the placement box 1 is fixedly connected to a connecting block 2. The top of the connecting block 2 is provided with a placement slot. Both ends of the placement slot are There are placement grooves, and a restriction and fixing mechanism is fixedly installed between the two placement grooves. A temperature control device 3 is installed inside the placement box 1. The restriction and fixation mechanism includes a first motor 4. One end of the two placement grooves is provided. There are connecting grooves, a limited through hole is provided between the two connecting grooves, a two-way screw 5 is rotatably connected between the two connecting grooves, a motor slot is provided at one end of the limiting through hole, and one end of the first motor 4 It is fixedly connected to one end inside the motor slot. The output end of the first motor 4 and the outer wall of the two-way screw 5 are both fixedly connected with a stabilizing gear 6. The two stabilizing gears 6 mesh with each other. There are two screws on the outer wall of the two-way screw 5. Stabilizing screw sleeves 7, one end of the two stabilizing screw sleeves 7 is fixedly connected with a support plate 8, and the two supporting ends close to each other are equipped with arc limiting plates 9 through a buffer mechanism. The buffer mechanism includes a buffer cylinder 10, and the buffer cylinder 10 One end is fixedly connected to one end of the support plate 8. A buffer slide 11 is slidingly connected to the inside of the buffer cylinder 10. A buffer spring 12 is installed between one end of the buffer slide 11 and one end inside the buffer cylinder 10.
