[0035] The working principle and use process of the present invention are as follows: before use, it is selected whether to expand the expandable operating table 21 according to the size of the animal. If expansion is not required, it can be used directly. If expansion is required, the detachable expansion plate 20 placed in the limit support square tube 22 is pulled out, and then the two detachable expansion plates 20 are respectively plugged into the two sides of the expandable operating table 21 (only one side can be expanded), so as to realize the rapid expansion of the expandable operating table 21, and then the animal waiting for surgery is placed at any position on the expandable operating table 21 (it is not necessary to place it in the middle of the expandable operating table 21), and then the postures of the four deformable positioning mechanisms 3 are adjusted respectively, and then the limbs of the animal are reliably fixed by the four deformable positioning mechanisms 3, and the fixed posture of the animal can be adjusted for suitability (for example, sometimes it is necessary to tilt the target limb of the animal upward or tilt it outward for surgery);

[0036] When the deformable positioning mechanism 3 needs to be adjusted, the fixing effect of the first adjustable fastening screw 310 is first released, and then the sliding limit support block 311 is pulled to make it slide along the limit support slide rail 23 until it is suitable, and then the fixing effect of the first adjustable fastening screw 310 is restored, and then the fixing effect of the second adjustable fastening screw 313 is released, so that the first deformable position adjustment member 32 can be rotated through the first limit hollow support tube 314, and at the same time, the fixing effect of the third adjustable fastening screw 332, the fourth adjustable fastening screw 335 and the fifth adjustable fastening screw 336 are released. At this time, the user can rotate the third limit fixing base plate 333 180°, so that the second deformable position adjustment member 34 is located above the first deformable position adjustment member 32, and then The user can then adjust the second deformable position adjusting member 34 in two degrees of freedom by rotating the second limit hollow support tube 330 and the fourth limit fixed base plate 337, and adjust the length of the first deformable position adjusting member 32 and the second deformable position adjusting member 34, so as to quickly adjust the limit fixing strap 35 to the target position, and then restore the fixing function of the second adjustable fastening screw 313, the third adjustable fastening screw 332, the fourth adjustable fastening screw 335 and the fifth adjustable fastening screw 336, and then reliably fix the animal's limbs through the limit fixing strap 35. In short, the user only needs to turn a few screws to arbitrarily adjust the position and posture of the second deformable position adjusting member 34, making the use of the limb positioning frame more convenient and humane;

[0037] When the limb positioning frame is used, the user can restore the deformable positioning mechanism 3 to the original position. Figure 4 In the initial form shown, the deformable positioning mechanism 3 can be stored at this time, so that the limb positioning frame takes up less space when stored, and through the mutual cooperation of multiple structures, multiple personalized adjustments are provided for each limb fixing structure (that is, the deformable positioning mechanism 3). Through the mutual cooperation of multiple adjustment methods, the limb positioning frame can not only fix animals of different sizes, but also reliably adjust and fix the fixed posture of the animal according to surgical requirements, which significantly improves the applicability of the limb positioning frame. Secondly, the present invention has anti-slip and expansion functions, which makes the functions of the limb positioning frame richer, and the invention has a simple structure and is easy to use, so it is worthy of promotion and use.
