[0030] Embodiment three:

[0031] As shown in Figure 3 and Figure 4 The difference between the embodiment and the embodiments 1 and 2 is that the top end of the inner surface of the supporting frame 702 is provided with a sliding groove 811 at the positions on both sides of the connecting barrel 805, the inner surface of the sliding groove 811 is fixedly connected with a limiting rod 812, the outer surface of the limiting rod 812 is slidably connected with a sliding block 813, the outer surface of the limiting rod 812 is provided with a spring one 814 near one end, one end of the spring one 814 is fixedly connected with the sliding groove 811, the other end is fixedly connected with the sliding block 813, and the sliding block 813 is slidably connected with the sliding groove 811, the elasticity of the spring one 814 is matched with the elasticity of the torsion spring 810, so that the resistance of the rotation of the connecting barrel 805 can be further increased.

[0032] The lower end of the outer surface of the sliding block 813 is fixedly connected with a fixed rod 815, the bottom end of the outer surface of the fixed rod 815 is fixedly connected with a tooth 816 near one side of the gear one 807, the outer surface of the connecting barrel 805 is provided with a traction rope 817 at positions corresponding to the two groups of sliding blocks 813, one end of the traction rope 817 is fixedly connected with the connecting barrel 805, and the other end is fixedly connected with the sliding block 813, the winding directions of the two groups of traction ropes 817 are opposite, in the process of the rotation of the connecting barrel 805, one group of traction ropes 817 is in a winding state, the sliding block 813 corresponding to the group of traction ropes 817 moves in the direction close to the connecting barrel 805 under the pulling of the traction rope 817, the fixed rod 815 drives the tooth 816 to move in the direction of the gear one 807, the tooth 816 is engaged with the gear, the gear one 807 is prevented from continuing to rotate, the stability of the bolt 704 is ensured, and the anti-deviation effect of the device can be further enhanced.

[0033] The working principle and process of the application:

[0034] Step one, first install the base 5 to the corresponding position, make the support frame 702 correspond to the preset part arranged on the bottom of the vehicle, then press the base 5 so that it cannot move, then use the bolt 704 to pass through the threaded hole one 705 and the threaded hole two 806, and make it threadedly connected with the preset part arranged on the bottom of the vehicle, so as to fix the base 5 and prevent the CT bed 1 from moving along the direction perpendicular to the bolt 704;

[0035] Step two, then use the connecting part to install the CT bed 1 on the upper end outer surface of the base 5, at this time the CT bed 1 corresponds to the CT machine 2, since the base 5 is fixed by the bolt 704, therefore when the CT bed 1 deviates to one side during use, the CT bed 1 will not move along the direction perpendicular to the bolt 704, the support column 6 will only rotate a certain angle around the support frame 702, and the two groups of connecting rods 803 will drive the connecting ring 801 to rotate, and the connecting cylinder 805 rotates with the connecting ring 801;

[0036] Step three, the gear one 807 rotates with the connecting cylinder 805, the gear two 808 drives the rotating rod 809 to rotate under the drive of the gear one 807, the rotating rod 809 twists the torsion spring 810, so that the elastic force of the torsion spring 810 can hinder the rotation of the gear one 807, increase the resistance of the rotation of the CT bed 1, and the restoring ability of the torsion spring 810 can drive the gear two 808 to drive the gear one 807 to rotate to the direction of restoring to the original state;

[0037] Step four, during the rotation of the connecting cylinder 805, one group of traction ropes 817 is in a rolled state, therefore the sliding block 813 corresponding to the group of traction ropes 817 moves to the direction close to the connecting cylinder 805 under the pull of the traction rope 817, the fixed rod 815 drives the gear teeth 816 to move to the direction of the gear one 807, the gear teeth 816 are engaged with the gear one 807, preventing the gear one 807 from continuing to rotate, at the same time, the elasticity of the spring one 814 and the elasticity of the torsion spring 810 are matched, which can further increase the resistance of the rotation of the connecting cylinder 805, and then increase the difficulty of the deviation of the CT bed 1.

[0038] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
