[0032] Embodiment 1:

[0033] See also Figure 1-5 A large transmission ratio flange is assembled, including a No. 1 flange 1 and a No. 2 flange 11. The interior of the No. 1 flange 1 and the No. 2 flange 11 are both plugged with threaded rods 12. The interior of the threaded rod 12 is rotatably connected with a support rod 17. One side of the support rod 17 is rotatably connected with a No. 2 telescopic rod 19. One end of the threaded rod 12 is fixedly connected to a limiting block 16. One end of the No. 2 telescopic rod 19 is rotatably connected to the inner wall of the limiting block 16. The side of the support rod 17 away from the No. 2 telescopic rod 19 is in contact with one side of the No. 1 flange 1. A No. 2 spring 18 is sleeved on the outer wall of the No. 2 telescopic rod 19, and the two ends of the No. 2 spring 18 are respectively fixedly connected to the two ends of the No. 2 telescopic rod 19, the interior of the threaded rod 12 is slidably connected to the sliding rod 13, the end of the sliding rod 13 is fixedly connected to the No. 1 telescopic rod 15, and the end of the No. 1 telescopic rod 15 away from the sliding rod 13 is fixedly connected to the interior of the limit block 16, and the outer wall of the No. 1 telescopic rod 15 is sleeved with a No. 1 spring 14, and the two ends of the No. 1 spring 14 are respectively fixedly connected to the two ends of the No. 1 telescopic rod 15.

[0034] When the threaded rod 12 is inserted into the interior of the No. 1 flange 1 from one side of the No. 2 flange 11, the four support rods 17 are squeezed by the inner walls of the No. 2 flange 11 and the No. 1 flange 1 and rotate and gradually rotate to the interior of the receiving groove 23. At this time, the No. 2 spring 18 will undergo elastic deformation and store a certain amount of elastic potential energy. When the support rod 17 completely passes through the No. 1 flange 1, the No. 2 spring 18 in a compressed state is reset, thereby driving the support rod 17 to expand and reset, so as to complete the limiting of the No. 1 flange 1 on the outer wall of the threaded rod 12. If it is necessary to take the threaded rod 12 out of the No. 1 flange 1 and the No. 2 flange 11 again, the user can first push the threaded rod 12 a short distance in the direction of the No. 1 flange 1, and then press the sliding rod 13 so that one end of the sliding rod 13 squeezes the part of the support rod 17 located inside the threaded rod 12. At this time, the four support rods 17 will rotate and gradually rotate to the interior of the receiving groove 23, and then the user can pull the threaded rod 12 out of the No. 1 flange 1 and the No. 2 flange 11.

[0035] Embodiment 2:

[0036] See also Figure 1-5 A receiving groove 23 is provided on the outer wall of the threaded rod 12, and the support rod 17 is located inside the receiving groove 23. The length of the support rod 17 is less than the length of the receiving groove 23. A threaded block 2 is threadedly connected to the outer wall of the threaded rod 12. The side of the threaded block 2 close to the support rod 17 is fitted with one side of the No. 2 flange 11. A lever block 21 is fixedly connected to the outer wall of the threaded block 2. The four lever blocks 21 are equidistantly distributed. One end of the threaded rod 12 away from the support rod 17 is fixedly connected to a fixed block 22. The end of the sliding rod 13 away from the support rod 17 is located outside the threaded rod 12. Chamfers are provided on both sides of the limit block 16, and one side of the support rod 17 is fitted with one side of the limit block 16.

[0037] The locking cam 23 is used to lock the locking cam 24 and the locking cam 26. When the locking cam 26 is in a closed position, the locking cam 26 will lock the locking cam 26. The locking cam 26 will lock the locking cam 26.

[0038] The working principle of the utility model is as follows: when the threaded rod 12 is inserted from one side of the No. 2 flange 11 into the interior of the No. 1 flange 1, the four support rods 17 are squeezed by the inner walls of the No. 2 flange 11 and the No. 1 flange 1 and rotate and gradually rotate to the interior of the storage groove 23. At this time, the No. 2 spring 18 will undergo elastic deformation and store a certain amount of elastic potential energy. When the support rod 17 completely passes through the No. 1 flange 1, the No. 2 spring 18 in a compressed state is reset, thereby driving the expansion and reset of the support rod 17 to complete the limitation of the No. 1 flange 1 on the outer wall of the threaded rod 12. When the user inserts the threaded rod 12 into the interior of the No. 1 flange 1 and the No. 2 flange 11 and one side of the support rod 17 fits with one side of the No. 1 flange 1, use The user can rotate the threaded block 2 to gradually squeeze the No. 1 flange 1 and the No. 2 flange 11. Because one side of the support rod 17 fits with the chamfered profile on one side of the limit block 16, when the threaded block 2 squeezes the No. 1 flange 1 and the No. 2 flange 11, one side of the support rod 17 will always fit with one side of the No. 1 flange 1 and the support rod 17 will no longer rotate. When the user cannot rotate the threaded block 2, the assembly between the No. 1 flange 1 and the No. 2 flange 11 is completed. The lever block 21 is used for the user to rotate the threaded block 2, and the fixed block 22 protects the end of the sliding rod 13 located outside the threaded rod 12 to prevent it from sliding inside the threaded rod 12 due to external force.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
