Thus, the second locking portion 132 can only rotate within a predetermined range by the cooperation of the two limiting protrusions 208, so that the connection position of the locking unit can be flexibly adjusted according to the bone direction, and the locking unit can be better fixed.

As shown in fig. 1 to 8, in an embodiment, a shaping device is further provided, which includes the fixing unit in any one of the three embodiments, and further includes a flexible connector 300, one end of the flexible connector 300 is fixedly disposed on the connecting seat 100 through the first mounting hole 101, the other end of the flexible connector 300 passes through the first mounting hole 101 and the second mounting hole 102, the flexible connector 300 is provided with a limiting rack 310, and the limiting rack 310 is in locking fit with the latch 104.

When the fixing device is used, as shown in fig. 7 and 8, the fixing unit is used to form a reliable connection point on the fixing plate 200, and the fixing plate 200 is heated, so that the fixing plate 200 is heated and can be molded. In this process, the connecting seat 100 is not deformed, so that the fixing plate 200 can be wrapped along the bone direction of the patient; meanwhile, one end of the flexible connector 300 is fixed through the first mounting hole 101, and the other end of the flexible connector passes through the first mounting hole 101 and the second mounting hole 102, so that the limiting rack 310 is in locking fit with the latch 104. After the fixing plate 200 is used for completing the bone shaping, the position relation between the limiting rack 310 and the latch 104 is tensioned and adjusted, and in the process, the flexible connecting piece 300 cannot be loosened from the connecting seat 100 or between the connecting seat 100 and the fixing plate 200, so that the gap between the two connecting bodies 210 on the fixing plate 200 is proper, and the bone shaping effect can be ensured. This setting device has used this fixed unit for locking unit is connected reliably with fixed plate 200, can guarantee the design effect of the fixed unit after moulding, is favorable to guaranteeing the bone healing effect.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
