After clamping, the height of the clamping device is adjusted by the lifting piece, which is convenient for the medical staff to adjust at any time during polishing.
[0024] The lifting member includes a motor 11; the motor 11 is fixedly connected to the bottom end of the base 1; a first threaded rod 12 is provided at the output end of the motor 11; a threaded sleeve 13 is sleeved on the first threaded rod 12; one end of the threaded sleeve 13 is fixedly connected to the bottom end of the disc 2; a pair of sliding rods 14 are fixedly connected to the bottom end of the disc 2; the pair of sliding rods 14 are slidably connected to the top of the base 1 through sliding holes respectively. When working, by setting the motor 11 at the bottom end of the base 1, setting the first threaded rod 12 at the output end of the motor 11, and sleeved on the first threaded rod 12, when the motor 11 drives the first threaded rod 12 to rotate, the threaded sleeve 13 will drive the disc 2 to move upward, so that the height of the equipment is increased to a suitable position, which is convenient for medical staff to grind allogeneic bones. The pair of sliding rods 14 set at the bottom end of the disc 2 can prevent the disc 2 and the threaded sleeve 13 from rotating.
[0025] The top of the square plate 4 is provided with a T-shaped plate 15; the top of the T-shaped plate 15 is provided with a pair of through grooves 16; the pair of vertical plates 6 are slidably connected in the through grooves 16 respectively; the top of the T-shaped plate 15 is provided with a first groove 17; the pair of T-shaped placement plates 8 are both slidably connected in the first groove 17; the top of the circular ring 3 is fixedly connected with a first telescopic rod 18; the telescopic end of the first telescopic rod 18 is fixedly connected to the bottom of the T-shaped plate 15; the bottom of the T-shaped plate 15 is provided with a transmission member; the transmission member is used to drive the lifting of the T-shaped plate 15, and when working, by A T-shaped plate 15 is put on the end, and a pair of through grooves 16 are opened at the top of the T-shaped plate 15, so that a pair of vertical plates 6 can slide in the T shape, and a first groove 17 is opened at the top of the T-shaped plate 15, so that a pair of T-shaped placement plates 8 can adjust the distance between them, so as to facilitate the placement of allogeneic bones of different lengths. The height of the T-shaped plate 15 can be adjusted by the set transmission parts. Because the general clamping device requires the medical staff to hold the allogeneic bone for the clamping device to clamp when clamping, here the medical staff can directly place the allogeneic bone on the pair of T-shaped placement plates 8 first.

A pair of sliding rods 14 set at the bottom end of the disc 2 can prevent the disc 2 and the threaded sleeve 13 from rotating. By putting a T-shaped plate 15 on the top of the square plate 4, and opening a pair of through grooves 16 on the top of the T-shaped plate 15, a pair of vertical plates 6 can slide in the T shape, and by opening a first groove 17 on the top of the T-shaped plate 15, a pair of T-shaped placement plates 8 can adjust the distance between them, which is convenient for placing allogeneic bones of different lengths. The height of the T-shaped plate 15 can be adjusted by the set transmission member. Because the general clamping device requires medical staff to hold the allogeneic bone for the clamping device to clamp when clamping, here the medical staff can directly Then, the allogeneic bone is placed on a pair of T-shaped placement plates 8 first, and a pair of first connecting blocks 19 are set on the bidirectional threaded rod 9, and then a pair of second connecting blocks 20 are set at the bottom end of the T-shaped plate 15, and the first connecting block 19 and the second connecting block 20 are connected through the connecting plate 21. When the medical staff rotates the bidirectional threaded rod 9, the pair of first connecting blocks 19 will also move inward at the same time, so that the position of the T-shaped plate 15 is raised. Due to the setting, when the clamping plate 7 has not yet contacted the allogeneic bone, the T-shaped plate 15 will reach the set position, waiting for the clamping plate 7 to clamp the allogeneic bone on the T-shaped placement plate 8, and a group of second grooves 22 are respectively opened on the clamping surfaces of the pair of clamping plates 7, and a group of second grooves 22 are respectively fixed. A group of elastic telescopic rods 23, when a pair of clamping plates 7 are adjusted and moved inward at the same time through the bidirectional threaded rods 9, these elastic telescopic rods 23 will shrink according to the shape of the allogeneic bone. The elastic telescopic rods 23 at the edge of the allogeneic bone will outline the shape of the allogeneic bone and restrain the allogeneic bone, thereby increasing the clamping effect of the clamping plate 7, and preventing the allogeneic bone from sliding during grinding and causing accidents during grinding. By opening a third groove 24 at the top of the disc 2 and allowing the ring 3 to be rotatably connected in the third groove 24, medical staff can adjust the direction angle by rotating the ring 3 when grinding the allogeneic bone. The medical staff no longer needs to walk to adjust the grinding angle. This step can save the time of medical staff walking and adjusting, thereby improving the grinding efficiency.
