[0024] Embodiment 1

[0025] See also Figure 1-Figure 6 The utility model provides a technical solution: a medical plasma centrifuge turntable processing fixture, comprising a body 1 and two clamping blocks 6, the clamping blocks 6 on the left and right sides are symmetrically distributed, and the two clamping blocks 6 are used together so that the clamping blocks 6 can clamp the turntable, and the top of the body 1 is slidably connected to two sliders 2, and the clamping blocks 6 can be driven to move by moving the sliders 2. Two guide rods 3 are inserted into the interior of the sliders 2, and the outer sliding connection of the guide rods 3 is provided with a connecting block 4, and the guide rods 3 play a limiting role in the connecting block 4, so that the connecting block 4 can slide stably, and the adjacent sides of the left and right connecting blocks 4 are fixedly connected with a placement block 5, and the interior of the placement block 5 is slidably connected with two extension blocks 7, and the placement block 5 plays a limiting role in the extension block 7, so that the clamping block 6 can be stably installed in the interior of the placement block 5, and the front and rear extension blocks 7 are symmetrically distributed, and the left and right extension blocks 7 are respectively fixedly connected to the separated sides of the two clamping blocks 6, so that the installation of the clamping block 6 is more stable.

[0026] By moving the slider 2, the slider 2 can drive the clamping block 6 to move through the guide rod 3, the connecting block 4 and the placement block 5, so that the clamping block 6 can clamp the turntable.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to realize the convenient replacement of the clamping block 6, two placement grooves 8 are provided inside the placement block 5, and the top of the placement block 5 is rotatably connected with a rotating shaft 9, and the placement block 5 limits the rotating shaft 9, so that the rotating shaft 9 can rotate smoothly, and the outside of the rotating shaft 9 is fixedly connected with two pull ropes 10, and the outside of the pull rope 10 is slidably connected to the inside of the placement groove 8, and the placement groove 8 limits the pull rope 10, so that the pull rope 10 will not deviate when moving, and the outside of the pull rope 10 is provided with a spring 17, and the pull rope 10 limits the external spring 17, so that the spring 17 is squeezed or made No deviation will occur during the reset movement. One end of the spring 17 is fixedly connected to the inner wall of the placement groove 8. The end of the pull rope 10 away from the rotating shaft 9 is fixedly connected to the block 11. The other end of the spring 17 is fixedly connected to the side of the block 11 close to the pull rope 10. The outside of the block 11 is slidably connected to the inside of the placement groove 8. The placement groove 8 limits the block 11 so that it will not shake when squeezing the spring 17. The placement block 5 has slots 12 on both the front and back sides. The slot 12 is connected to the placement groove 8, so that the block 11 can enter the inside of the slot 12. The block 11 penetrates the extension block 7 and engages with the inside of the slot 12.

[0029] When the clamp block 6 needs to be replaced, the rotating shaft 9 is rotated so that the rotating shaft 9 can wrap the pull rope 10 around its outside, and then the pull rope 10 can pull the clamp block 11 to squeeze the spring 17 to deform, and at the same time the clamp block 11 can be disengaged from the inside of the slot 12 and the extension block 7, and then by pulling the clamp block 6 inward, the extension block 7 outside the clamp block 6 can be disengaged from the inside of the placement block 5, so that the clamp block 6 can be easily disassembled. Conversely, by sliding the extension block 7 outside the clamp block 6 into the inside of the placement block 5 and then loosening the rotating shaft 9, the spring 17 can perform a reset movement, and then the spring 17 can push the clamp block 11 to penetrate the extension block 7 and engage with the inside of the slot 12, so that the clamp block 6 can be easily installed. This process does not require the use of a screwdriver to remove the screws, which makes replacement more convenient and does not affect the processing efficiency of the turntable.

[0030] Embodiment 3

[0031] On the basis of the second embodiment, in order to realize the installation of guide rods 3 of different lengths, the bottom end of the slider 2 is fixedly connected with a mounting block 16, and the mounting block 16 is of a special-shaped design, so that the mounting block 16 will not shake after being inserted into the interior of the slider 2, and the outside of the mounting block 16 is inserted into the interior of the slider 2, and the inside of the mounting block 16 is plugged with a latch 13, and the latch 13 can further limit the mounting block 16, thereby making the installation of the mounting block 16 more stable, and the latch 13 is slidably connected to the interior of the slider 2, and the outside of the latch 13 is fixedly connected with multiple rubber rings 14.

[0032] When the guide rod 3 needs to be installed, the mounting block 16 and the guide rod 3 are slid into the interior of the slider 2, thereby sliding the latch 13 into the interior of the slider 2 and the mounting block 16, so that the mounting block 16 can be further limited. After the latch 13 slides into the interior of the slider 2, the rubber ring 14 can fit tightly with the interior of the slider 2, so that the mounting block 16 will not shake easily, thereby allowing the mounting block 16 to be stably installed in the interior of the slider 2.

[0033] Embodiment 4

[0034] On the basis of the third embodiment, in order to achieve height adjustment of the clamping block 6 , a plurality of through holes are opened inside the guide rod 3 , the internal thread of the connecting block 4 is connected with a bolt 15 , and the bolt 15 passes through the through holes inside the guide rod 3 .

[0035] By unscrewing the bolt 15 from the through hole inside the guide rod 3, the connecting block 4 is slid up and down, so that the connecting block 4 can drive the clamping block 6 to slide through the placement block 5. When the clamping block 6 moves to the appropriate through hole of the guide rod 3, the bolt 15 is screwed into the through hole of the guide rod 3 and the inside of the slider 2, thereby fixing the height of the clamping block 6.

[0036] In actual use, by rotating the rotating shaft 9, the rotating shaft 9 can wrap the pull rope 10 at the corresponding position around its outside, so that the pull rope 10 can pull the clamping block 11 out of the clamping slot 12 and the inside of the extension block 7, and can squeeze the spring 17 to produce deformation. At this time, the clamping block 6 can be pulled so that the clamping block 6 can be detached from the placement block 5. Conversely, by sliding the extension block 7 outside the clamping block 6 into the inside of the placement block 5, and then loosening the rotating shaft 9, the spring 17 can perform a reset movement, and then the spring 17 can push the clamping block 11 to penetrate the extension block 7 and engage with the inside of the clamping slot 12, so that the clamping block 6 can be easily installed. This process does not require the use of a screwdriver to remove the screws, which makes replacement more convenient and does not affect the processing efficiency of the turntable.
