A special-shaped block 4 is connected, a fixing rod 5 is fixedly connected to the inside of the shell 1, and two fixing blocks 6 are fixedly connected to the outside of the fixing rod 5. A reset component is arranged on the outside of the fixing rod 5, so that the clamping inside the device can be reset without being subjected to force. The reset component includes two springs 7, and the two springs 7 are sleeved on the outside of the fixing rod 5, one end of the spring 7 is fixedly connected to the outside of the fixing block 6, and the other end of the spring 7 is fixedly connected to the outside of the clamping rod 13. Slide rods 8 are slidably connected to the left and right sides of the shell 1, and a moving block 9 is fixedly connected to the adjacent side of the two slide rods 8. An elastic component is arranged on the outside of the slide rod 8 to provide power to the structures at both ends by storing elastic force.
[0023] The elastic component includes two springs 10, and the two springs 10 are sleeved on the outside of the sliding rod 8. One end of the spring 10 is fixedly connected to the inner wall of the outer shell 1, and the other end of the spring 10 is fixedly connected to the outside of the moving block 9. The top of the moving block 9 is fixedly connected with a fixed shaft 11 as a base point for the rotation of the external structure. The top of the fixed shaft 11 is fixedly connected with a limiting plate 12, and the external rotation of the fixed shaft 11 is connected with a clamping rod 13. The internal sliding connection of the two clamping rods 13 is connected to the outside of the fixed rod 5. The top of the clamping rod 13 is fixedly connected with a rotating shaft 14, and the top of the rotating shaft 14 is fixedly connected with a rotating round block 15. The outside of the special-shaped block 4 contacts with the adjacent side of the two rotating round blocks 15.
[0024] like Figure 1 and Figure 3 As shown: the right side of the outside of the clamping rod 13 is fixedly connected to a base 16, the inner wall of the base 16 is slidably connected to two connecting semicircles 17, the inside of the connecting semicircle 17 is slidably connected to two connecting semicircles 2 18, and the outside of the connecting semicircle 2 18 is fixedly connected to a plurality of rubber beads 19.
[0025] Compared with some existing technologies, the above content enables the clamping mechanism on the movable block 9 to move through the spring 2 10 during use of the device, so that the clamping mechanism can move within a certain range, and the clamping mechanism can adapt to objects of different shapes through multiple rotating semicircular bodies, thereby solving the problem that some devices cannot adapt to the position of the object during use and some devices are difficult to fix when facing objects with more complex shapes during use.
[0026] Working principle: First, place the object between the clamping mechanisms, then start the hydraulic cylinder 2 to make the central axis 3 move inside the housing 1. Because the special-shaped block 4 is fixed at one end of the central axis 3, and the outside of the special-shaped block 4 is in contact with the two rotating circular blocks 15, the clamping rod 13 at the bottom of the rotating shaft 14 is driven to rotate around the fixed axis 11. During the rotation, the moving block 9 slides on the sliding rod 8, thereby clamping the object according to its position. The base 16 is fixed at one end of the clamping rod 13, so that the base 16 opens The connecting semicircle 17 with a groove and rotating on the groove will rotate. Similarly, the connecting semicircle 2 18 also rotates inside the connecting semicircle 17. Driven by multiple semicircular structures, the clamping mechanism can adapt well to the shape of the object. Multiple rubber beads 19 are inlaid on the outside of the connecting semicircle 2 18 to increase the friction. After the object is no longer needed to be fixed, the central axis 3 pulls the special-shaped block 4 backward so that the clamping rod 13 is reset under the elastic force of the spring 1 7, and the moving block 9 will return to its position under the action of the two springs 2 10.
