[0032] Both ends of the top of the installation box 3 are fixedly connected with symmetrically distributed fixing seats 11, and both sides of the inside of the installation box 3 are fixedly connected with symmetrically distributed positioning bars 12, and a track structure is formed between the two positioning bars 12 and the bottom of the installation box 3.

[0033] A screw rod 13 is rotatably connected to the inner side of the two fixing seats 11 on the top of the installation box 3, and both ends of the screw rod 13 extend to the outside of the fixing seats 11, and the end of the screw rod 13 is fixedly connected to a rotating handle.

The support block 4 is set as an L-shaped structure, and a threaded seat 14 is fixedly connected to the top of the lower end of the support block 4, and the threaded seat 14 is provided with threads inside.

[0038] Example 2:

[0039] Based on the first embodiment, the specific working principle is as follows:

[0040] The auxiliary bracket for the production and transportation of limited concrete blocks is provided with a connecting shaft 8, a cross shaft 9 and a fixed shaft 10 to form a universal joint structure. During the transportation of concrete blocks, the transport rollers 7 rotate inside the fixed rails 6, so that the concrete blocks move on the top of the transport rollers 7 to achieve the transportation effect of the concrete blocks. The fixed rails 6 are supported by two connecting rods 5. During the movement of the concrete blocks on the top of the transport rollers 7, the concrete blocks will impact the transport rollers 7, so that the transport structure formed by the fixed rails 6 and the transport rollers 7 is affected by the concrete blocks and vibrates. The two sides of the fixed rails 6 are fixed by the connecting rods 5, and opposite forces are applied to the two sides of the fixed rails 6 to achieve support for the fixed rails 6. A universal joint structure is formed by the connecting shaft 8, the cross shaft 9 and the fixed shaft 10. When the fixed track 6 vibrates, the connecting shaft 8 will be driven to rotate around the cross shaft 9. At the same time, the connecting shaft 8 drives the cross shaft 9 to rotate inside the fixed shaft 10. The rotation of the connecting shaft 8 is in the horizontal direction. At the same time, the cross shaft 9 is in the vertical direction when rotating inside the fixed shaft 10. Through the different rotation directions of the connecting shaft 8, the cross shaft 9 and the fixed shaft 10, the connecting shaft 8 can be arbitrarily moved in any direction within a certain space, so that the universal joint structure formed by the connecting shaft 8, the cross shaft 9 and the fixed shaft 10 can quickly absorb forces in different directions. When the transport roller 7 is in a high-frequency nonlinear vibration, the universal joint structure of the connecting rod 5 can quickly achieve a shock-absorbing effect on the transport roller 7.

[0041] The two connecting rods 5 are fixed to the fixed rails 6 by the connecting shafts 8 provided inside them, and the connecting shafts 8 and the fixed rails 6 are fixed to each other at the connection points by multiple bolts. The screw rod 13 is rotated so that the screw rod 13 rotates inside the threaded seats 14 at the tops of the two support blocks 4. Since the internal threads of the two threaded seats 14 are in opposite directions, and the threads at both ends of the two screw rods 13 are in opposite directions, when the screw rod 13 rotates inside the threaded seat 14, the screw rod 13 drives the threaded seat 14 at the same time, so that the two support blocks 4 move in opposite directions at the same time, thereby adjusting the distance between the two connecting rods 5, which is convenient for fixing fixed rails 6 of different widths. At the same time, two opposite forces are applied to the two connecting rods 5 by the two support blocks 4, so that the tension between the two connecting rods 5 and the fixed rails 6 is increased, so that the connecting rod 5 can more effectively support the fixed rails 6;

[0042] A spring 17 is provided between the two support blocks 4, and the spring 17 applies force to the two threaded seats 14 toward the two ends of the installation box 3, thereby applying force to the threaded seats 14 toward the two ends of the installation box 3 to prevent the screw rod 13 from rotating inside the threaded seat 14 due to vibration.
