[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] For an example, please refer to... Figure 1 , 2 3, 4, and 5, an adaptive clamping trolley includes a base frame 1, an annular frame 2 fixedly connected to the upper end of the base frame 1, a roller assembly at the rear end of the base frame 1, a set of push rods 3 connected to the roller assembly, the roller assembly including a crossbar 4 fixedly connected to the rear end of the base frame 1, wheels 5 installed at both ends of the crossbar 4, the base frame 1 being integral and U-shaped, adjustable adaptive clamping structures installed on both front ends of the base frame 1, the adaptive clamping structures including adjustment components and clamping structures; an adjustable bottom support structure is provided at the lower middle position of the rear end of the base frame 1 for supporting the bottom end of the transported object, and a floating support component is provided above the middle rear end of the base frame 1, the floating support component and the adaptive clamping structures on both sides working together to form three-point support for the side of the transported object.

[0029] The adaptive clamping structure is designed so that when in use, the push rod 3 is pushed to make the base frame 1 snap into both sides of the transported object. At this time, the adaptive clamping structure abuts against the side of the transported object and adjusts to the clamping state according to the side of the transported object. After clamping is completed, the rear end of the transported object abuts against the floating support, forming a three-point support for the side of the transported object. The clamping can be achieved without moving the transported object.

[0030] The bottom support structure can be adjusted to the bottom of the object being transported, providing support to the bottom of the object. Combined with the clamping structure, this ensures the stability of the object during transportation.

[0031] Please refer to Figure 1 , 2 3, 4, and 5, the adjusting component includes an upper connecting frame 8 that is slidably sleeved on the outside of the base frame 1, a lower connecting frame 7 that is fixedly connected to the lower end of the upper connecting frame 8, a clamping structure that is slidably disposed inside the lower connecting frame 7, a fastening screw that is provided at the upper end of the upper connecting frame 8, and a fastening screw that is provided at the front end of the lower connecting frame 7 to limit and fix the clamping structure. The clamping structure includes a gripper rod 6, a gripper mounting end 14 that is provided at one end of the inner side of the gripper rod 6, a mating end 15 that is rotatably connected inside the gripper mounting end 14, and a gripper 16 that is fixedly connected to one side of the mating end 15. A clamping piece 17 is sleeved on the outer side of the gripper 16. An elastic element is connected between the two sides of the gripper rod 6 and the two sides of the gripper 16. The elastic element is a gripper spring 18. A connecting ring 19 is fixedly connected to the two sides of the gripper rod 6. One end of the gripper spring 18 is hooked to the connecting ring 19, and the other end of the gripper spring 18 is hooked to the gripper 16.

[0032] The upper connecting frame 8 can be adjusted relative to the base frame 1, and the gripper rod 6 can be adjusted relative to the lower connecting frame 7 to meet the needs of handling and clamping various sizes of transported items. The gripper 16 and the gripper mounting end 14 are hinged together and connected by the gripper spring 18. When the gripper is clamped to both sides of the transported item, the gripper 16 contacts the side of the transported item. The gripper 16 can be adjusted relative to the side of the transported item, so that the gripper spring 18 deforms. After running to the clamping state, the position of the gripper 16 on both sides remains stable, and the rear end of the transported item abuts against the floating support, forming a three-point support for the transported item.

[0033] Please refer to Figure 1 , 23, 4, and 5, the floating support includes a mounting frame 20 and a round tube 21 fixedly connected to the base frame 1.
