[0024] See also Figures 1 to 4 , a bone shearing pliers that is easy to adjust, comprises a first shearing handle 1, a second shearing handle 2, a first scissors head 3 and a second scissors head 4, the first shearing handle 1 is movably connected to the second shearing handle 2, the first scissors head 3 and the second scissors head 4 are movably connected, and the first scissors head 3 is movably connected to the first shearing handle 1, and the second scissors head 4 is movably connected to the second shearing handle 2, the first shearing handle 1 is also provided with a first torque sleeve 5 and a plurality of first threaded holes 6, the first torque sleeve 5 is provided with a first anti-slip butterfly screw 7, the first torque sleeve 5 is movably sleeved on the first shearing handle 1, the first anti-slip butterfly screw 7 cooperates with the first threaded hole 6, the second shearing handle 2 is provided with a second torque sleeve 8 and a plurality of second threaded holes 9, the second torque sleeve 8 is provided with a second anti-slip butterfly screw 10, and the second anti-slip butterfly screw 10 cooperates with the second threaded hole 9.

[0025] Specifically, the first shearing handle 1 is provided with a first connecting portion 11, and the second shearing handle 2 is provided with a second connecting portion 12. The first connecting portion 11 and the second connecting portion 12 are connected via a rotatable pin.

[0026] Specifically, the first scissors handle 1 is provided with a third connection portion 13 , the second scissors handle 2 is provided with a fourth connection portion 14 , the first scissors head 3 is provided with a fifth connection portion 15 , and the second scissors head is provided with a sixth connection portion 16 .

[0027] Specifically, the third connection part 13 and the fifth connection part 15 are connected via a rotatable pin, and the fourth connection part 14 and the sixth connection part 16 are connected via a rotatable pin.

[0028] Specifically, the first scissor head 3 is provided with a seventh connection part 17, the second scissor head 4 is provided with an eighth connection part 18, and the seventh connection part 17 and the eighth connection part 18 are connected via a rotatable pin.

[0029] Specifically, both the first scissor handle 1 and the second scissor handle 2 are provided with a shielding portion 19, and the shielding portion 19 is used to enable the holding hand to slide toward the scissor head of the bone forceps when in use.

[0030] Specifically, the first torque sleeve 5 and the second torque sleeve 8 are both made of stainless steel.

[0031] Specifically, a plurality of first threaded holes 6 are equidistantly arranged on the first shearing handle 1 , and a plurality of second threaded holes 9 are equidistantly arranged on the second shearing handle 2 .

[0032] Working principle: The first torque sleeve 5 is arranged on the first scissors handle 1, and the second torque sleeve 8 is arranged on the second scissors handle 2. When encountering relatively hard tissue or bone during surgery, the surgeon only needs to loosen the first anti-slipping butterfly screw 7 and the second anti-slipping butterfly screw 10, and then pull out the first torque sleeve 5 and the second torque sleeve 8 to an appropriate length and then use the first anti-slipping butterfly screw 7 and the second anti-slipping butterfly screw 10 to fix the first torque sleeve 5 and the second torque sleeve 8 respectively, so as to achieve the purpose of increasing the length of the scissors handle, thereby achieving the purpose of increasing the bite force between the first scissors head and the second scissors head without exerting a lot of force, so as to achieve the purpose of easily cutting off bones or hard tissues.

[0033] During use, the operator holds the first torque sleeve 5 and the second torque sleeve 8 at the same time and squeezes them tightly. During this process, the first connecting part 11 and the second connecting part 12 rotate relative to each other, driving the third connecting part 13 and the fourth connecting part 14 to move in opposite directions, and the distance between the two increases. At this time, since the fifth connecting part 15 and the third connecting part 13 can rotate relative to each other, and the sixth connecting part 16 and the fourth connecting part 14 can also rotate relative to each other, the fifth connecting part 15 and the sixth connecting part also move in opposite directions, and the distance between the two increases. In addition, the seventh connecting part 17 and the eighth connecting part 18 are connected by a rotatable pin, so the first scissors head 3 and the second scissors head 4 move away from one end of the first shear handle 1 in opposite directions, and the distance between the two is reduced, achieving the purpose of cutting bones or hard tissues.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
