When the two resetting support plates 1 are close to each other, the two sides of the resetting support plate 1 bulge inward to adapt to the shape of the fracture site of the calcaneus, thereby resetting the fracture site of the patient.

[0038] See also Figures 1 to 4 The positioning assembly includes a motor 7, a screw rod 8, a driven block 9 and a driven bar 10. The motor 7 is installed on the adjacent connecting frame 3. The connecting frame 3 is provided with a mounting groove matching the motor 7, which is convenient for stable installation of the motor 7, and the motor 7 is set to automatically perform forward and reverse movements at a certain angle.
