the first adjustment 11 is rotated so that the first adjustment 11 moves downward; the downward movement of the first adjustment 11 presses the second adjustment disc 14, causing the second adjustment disc 14 to move towards the side on which the third adjustment disc 17 is mounted; the movement of the second adjusting disk 14 towards the side on which the third adjusting disk 17 is mounted presses the first spring 15; the third adjusting disk 17 is pushed to move by the first spring 15; when the third adjusting disk 17 moves, the third adjusting disk 17 loses the constraint of the corresponding second adjusting disk 12; at this time, under the action of the third spring 20 and the fourth spring 21, the slider 19 moves toward the side on which the fourth spring 21 is mounted; during the movement of the slider 19, when the first mark 22 on the second adjustment 12 is aligned with the corresponding second mark 28, the first adjustment 11 is adjusted such that the first adjustment 11 rotates in reverse for 0.5 revolutions; the contact between the third adjusting disk 17 and the corresponding second adjusting disk 12 is now zero pressure contact; the elastic modulus of the integral supporting plate is close to that of the bone by adjusting the compression elasticity of the two second springs 18 in the two adjusting mechanisms 2; when the supporting plate swings along with the bone, the supporting plate can adapt to smaller deformation of the bone; the support plate is prevented from influencing the swing of the bone; when in use for a long time; when the elastic coefficient of the second spring 18 is changed, the compression elastic force of the second spring 18 between the third adjusting disk 17 and the first adjusting disk 13 is changed; at this time, the manual adjustment first adjustment 11 rotates, so that the first adjustment 11 moves downwards; the downward movement of the first adjustment 11 presses the second adjustment disc 14, causing the second adjustment disc 14 to move towards the side on which the third adjustment disc 17 is mounted; the movement of the second adjusting disk 14 towards the side on which the third adjusting disk 17 is mounted presses the first spring 15; the third adjusting disk 17 is pushed to move by the first spring 15; the movement of the third adjusting disk 17 compresses the second spring 18; increasing the compression spring force of the second spring 18 between the third adjusting disk 17 and the first adjusting disk 13; thereby again bringing the modulus of elasticity of the integral buttress plate close to that of bone; when the supporting plate swings along with the bone, the supporting plate can adapt to smaller deformation of the bone; the support plate is prevented from influencing the swing of the bone; the semicircular snap ring 26 is used for limiting the third adjusting disk 17 and preventing the third adjusting disk from sliding to the other side corresponding to the second adjusting disk 12. The design of the present invention is that the stopper 29 is used to prevent the second adjuster 12 from being pushed backward by the third adjuster disc 17 during the process of pressing the third adjuster disc 17.
The specific implementation mode is as follows: when a person uses the support plate designed according to the present invention, the first adjustment 11 is adjusted such that the first adjustment 11 is rotated before use; the first adjusting block 11 is installed on the square mounting block 16 through the matching of the external thread on the first adjusting block and the internal thread on the inner side of the circular hole 25 formed on the square mounting block 16; the first adjustment 11 is rotated so that the first adjustment 11 moves downward; the downward movement of the first adjustment 11 presses the second adjustment disc 14, causing the second adjustment disc 14 to move towards the side on which the third adjustment disc 17 is mounted; the movement of the second adjusting disk 14 towards the side on which the third adjusting disk 17 is mounted presses the first spring 15; the third adjusting disk 17 is pushed to move by the first spring 15; when the third adjusting disk 17 moves, the third adjusting disk 17 loses the constraint of the corresponding second adjusting disk 12; at this time, under the action of the third spring 20 and the fourth spring 21, the slider 19 moves toward the side on which the fourth spring 21 is mounted; during the movement of the slider 19, when the first mark 22 on the second adjustment 12 is aligned with the corresponding second mark 28, the first adjustment 11 is adjusted such that the first adjustment 11 rotates in reverse for 0.5 revolutions; when the adjustment is completed, the contact between the third adjusting disk 17 and the corresponding semicircular clamping ring 26 is zero-pressure contact; adjusting the second adjustment 12 at this time causes the second adjustment 12 to rotate; the second adjusting device 12 is arranged on the sliding block 19 through the matching of the external thread on the second adjusting device and the internal thread on the inner side of the circular hole 25 formed on the sliding block 19; so that rotation of the second adjustment 12 now causes the second adjustment 12 to move downwardly; the downward movement of the second adjustment member 12 presses the third adjustment disk 17 so that the third adjustment disk 17 moves toward the side on which the first adjustment disk 13 is mounted; the third adjusting disk 17, moving towards the side where the first adjusting disk 13 is mounted, presses the second spring 18; finally, the compression elasticity of the second spring 18 between the third adjusting disk 17 and the first adjusting disk 13 is fixed; the elastic modulus of the integral supporting plate is close to that of the bone by adjusting the compression elasticity of the two second springs 18 in the two adjusting mechanisms 2; when the supporting plate swings along with the bone, the supporting plate can adapt to smaller deformation of the bone; preventing the support plate from affecting the swinging of the bone.
