[0039] In the stage of propping up the bone to be sawn, place the bone to be sawn in the elastic sheet 425 of the placing block 424, and rotate the rotating ring 418. The rotating ring 418 is fixedly connected to the lead screw 415. Left-handed and right-handed helical protrusions are arranged on the lead screw 415. The linkage cover 413 is threaded on different helical protrusions. By rotating the lead screw 415, the linkage cover 413 is displaced. At both ends of the linkage cover 413, third receiving blocks 419 are fixedly connected. At the lower head of the third receiving block 419, a roller 410 is screwed. By means of the linkage cover 413, the roller 410 is displaced in the slideway 217.

One end of each of the two linkage bars five 521 is fixedly connected to a circular block 522. A helical beryllium copper wire 523 is arranged on the linkage bar five 521. Two ends of the helical beryllium copper wire 523 are respectively fixedly connected to the inner wall surface of the adapter plate 518 and the circular block 522. The other end of each of the two linkage bars five 521 is fixedly connected to a vertical plate 524. The lower head of the vertical plate 524 is fixedly connected to the horizontal block 219. A convex block 525 is fixedly connected to the outer wall surface of the adapter plate 518. A traction bar 526 is fixedly connected to the convex block 525.

[0041] During the positioning stage of the bone sawing area, rotate the connection block four 514 of the horizontal block 219. The connection block four 514 causes the circular block 522 to rotate on the vertical block six 5, facilitating the contact between the connection block four 514 and the peripheral surface of the bone sawing area. Then press the connection block four 514 downward, causing the insertion piece 515 to press against the curved edge 519 of the adapter plate 518, facilitating the displacement of the adapter plate 518 on the linkage bar five 521 to pull the helical beryllium copper wire 523. When the insertion piece 515 contacts the curved edge 519, the adapter plate 518 returns to its original position via the elasticity of the helical beryllium copper wire 523, facilitating the positioning of the connection block four 514 for the bone sawing area.

[0042] The implementation method is specifically as follows: When sawing the bone, first position the bone sawing area. The center of the connection bar 312 is fixedly connected to a support block 314. The lower head of the support block 314 is fixedly connected to two vertical blocks 315. The lower head of the vertical blocks 315 is fixedly connected to a support piece 316. Two vertical bars 317 are fixedly connected to the upper wall surface of the support piece 316.

Pull the connection frames 324 at both ends of the saw blade 322 to saw the bone through the connection frames 324.

[0043] In the stage of propping up the bone to be sawn, place the bone to be sawn in the elastic piece 425 of the placement block 424, rotate the rotating ring 418. The rotating ring 418 is fixedly connected to the lead screw 415. Left-handed and right-handed helical protrusions are arranged on the lead screw 415. The linkage cover 413 is screwed onto different helical protrusions. By rotating the lead screw 415, the linkage cover 413 is displaced. The two ends of the linkage cover 413 are fixedly connected to the third receiving block 419. The lower head of the third receiving block 419 is rotatably connected with the wheel 410. By means of the linkage cover 413, the wheel 410 is displaced in the slideway 217. The lead screw 415 displaces the third connecting block 4 on the connecting rod 312, improving the smoothness of the displacement of the linkage cover 413. The linkage cover 413 props up the bone to be sawn through the placement block 424 of the fourth receiving block 422;

[0044] In the stage of positioning the bone to be sawn, rotate the fourth connecting block 514 of the transverse block 219. The fourth connecting block 514 makes the circular block 522 rotate on the sixth vertical block 5, facilitating the fourth connecting block 514 to contact the peripheral surface of the bone to be sawn. Then press down the fourth connecting block 514 to make the insert piece 515 squeeze the curved edge 519 of the connecting plate 518, facilitating the connecting plate 518 to displace on the fifth linkage rod 521 to pull the helical beryllium copper wire 523. When the insert piece 515 is connected in the curved edge 519, the connecting plate 518 returns to its original position through the elasticity of the helical beryllium copper wire 523, facilitating the positioning of the fourth connecting block 514 to the bone to be sawn.
