[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1: A material shape adaptive fixture, such as Figures 1 to 3 As shown, it includes a first clamp rod 21, a second clamp rod 22, a strength support rod 23, and two adaptive clamping mechanisms (not marked in the figure).

[0029] like Figures 1 to 3 As shown, the middle part of the first clamp rod 21 is rotatably connected to the middle part of one end face of the strength support rod 23, and the middle part of the second clamp rod 22 is rotatably connected to the middle part of the other end face of the strength support rod 23. A first lifting ear 211 is provided at one end of the first clamp rod 21 away from the second clamp rod 22, and a second lifting ear 221 is provided at one end of the second clamp rod 22 away from the first clamp rod 21. The first clamp rod 21 is provided with a plurality of first adjustment holes 212 arranged and distributed along its length direction, the second clamp rod 22 is provided with a plurality of second adjustment holes 222 arranged and distributed along its length direction, and the two end surfaces of the strength support rod 23 are symmetrically provided with a plurality of threaded holes 231 arranged and distributed along its length direction. A first connecting bolt 213 is provided between the first clamp rod 21 and the strength support rod 23, which passes through any one of the first adjustment holes 212 and is threadedly connected to any one of the threaded holes 231. A second connecting bolt 223 is provided between the second clamp rod 22 and the strength support rod 23, which passes through any one of the second adjustment holes 222 and is threadedly connected to any one of the threaded holes 231. The center line of the first connecting bolt 213 and the center line of the second connecting bolt 223 after installation do not coincide.

[0030] like Figure 1 and Figure 2As shown, the two adaptive clamping mechanisms are respectively provided with one end of the first clamp rod 21 away from the first lifting lug 211 and one end of the second clamp rod 22 away from the second lifting lug 221. The adaptive clamping mechanism comprises an A-direction rotating assembly 24, a B-direction rotating assembly 25 arranged on the A-direction rotating assembly 24, and a clamping block 26 arranged on the B-direction rotating assembly 25. The A-direction rotating assembly 24 is used to be installed on the first clamp rod 21 or the second clamp rod 22. The A-direction rotating assembly 24 allows the B-direction rotating assembly 25 and the clamping block 26 to rotate in the XZ plane to adapt to the side profile of the stone. The B-direction rotating assembly 25 allows the clamping block 26 to rotate in the YZ plane to make the stone naturally sag during the carrying process, keeping the center of gravity stable.

[0031] As shown in Figure 1 , Figure 2 and Figure 4 , the A-direction rotating assembly 24 comprises a rotating block 241, an A-rotation shaft 242, and a return spring 243. The A-rotation shaft 242 is used to be rotatably connected to the first clamp rod 21 or the second clamp rod 22. The rotating block 241 is rotatably arranged on the A-rotation shaft 242. One end of the return spring 243 is connected to the rotating block 241 and the other end is used to be connected to the crossbar portion of the first clamp rod 21 or the crossbar portion of the second clamp rod 22. The B-direction rotating assembly 25 is arranged on the rotating block 241. When the rotating block 241 is rotated by an external force, the return spring 243 exerts a force on the rotating block 241 with a restoring tendency. The B-direction rotating assembly 25 comprises a B-rotation shaft 251 arranged on the rotating block 241 and a rotating mounting block 252 rotatably connected to the end of the B-rotation shaft 251. The clamping block 26 is arranged on the rotating mounting block 252. Meanwhile, the clamping block 26 is made of flexible material. The clamping surface of the clamping block 26 is provided with a wavy pattern (not labeled in the figure).

[0032] Effect: During the use of the material shape adaptive clamp 2, when the first lifting lug 211 and the second lifting lug 221 are lifted upward, the two clamping blocks 26 rotate towards each other to clamp the stone. Because the A-direction rotating assembly 24 allows the B-direction rotating assembly 25 and the clamping block 26 to rotate in the XZ plane to adapt to the side profile of the stone, and because the B-direction rotating assembly 25 allows the clamping block 26 to rotate in the YZ plane, the clamped stone can naturally sag during the carrying process, keeping the center of gravity stable. Finally, the clamping block 26 can closely fit various shapes of carved stone, ensuring that the center of gravity of the stone is always located at the bottom during the carrying process, thereby significantly improving the stability and safety of the carrying process. During the stone turning process, the clamping position is changed, allowing the stone to be turned over by gravity, eliminating the lateral torsion between the clamping block 26 and the stone, reducing the wear of the clamping surface of the clamping block 26, and prolonging the service life.

[0033] The A-direction rotating assembly 24 comprises a rotating block 241, an A-rotation shaft 242, and a reset spring 243. The rotating block 241 is rotatably arranged on the A-rotation shaft 242, allowing the B-direction rotating assembly 25 and the clamping block 26 to rotate along the XZ plane, and the compression spring is compressed at this time. After the clamping of the stone is cancelled, the compression spring provides a restoring force, so that the rotating block 241 is reset to the initial position. The rotating mounting block 252 is rotatably arranged at the end of the B-rotation shaft 251, and the clamping block 26 is arranged on the rotating mounting block 252, allowing the clamping block 26 to rotate along the XY plane, so that the stone naturally droops during the carrying process, adapts to the change of the center of gravity of the stone, and keeps the center of gravity stable. The clamping block 26 is made of flexible material and has good elasticity and wear resistance. The clamping surface of the clamping block 26 is provided with a wave pattern to increase the friction between the stone and the clamping block 26, so as to prevent the stone from slipping during the carrying process.

[0034] The first clamping rod 21 and the strength support rod 23 are provided with a first connecting bolt 213 which is screwed in any one of the threaded holes 231 after passing through any one of the first adjusting holes 212. The second clamping rod 22 and the strength support rod 23 are provided with a second connecting bolt 223 which is screwed in any one of the threaded holes 231 after passing through any one of the second adjusting holes 222, so as to adjust the distance between the two clamping blocks 26 to adapt to different sizes of stones.

[0035] Embodiment 2: A carrying device with a material shape adaptive clamp, as shown in Figure 5 , comprising a carrying support 1, a material shape adaptive clamp 2, and a connecting device 3.

[0036] As shown in Figure 5 , the carrying support 1 comprises a lifting frame 11 and a lifting platform 12 which is arranged on the lifting frame 11 and can be lifted relative to the lifting frame 11. The power source can be a hydraulic cylinder.
