[0002] Pipe expanding machines are mainly used to expand the diameter of the pipe end so that the diameter of the pipe can meet people's practical needs. Pipe expanding machines are divided into automatic expanding machines and portable expanding machines according to portability. Portable expanding machines are mainly for easy carrying.

[0003] At present, some portable pipe expanding machines have a relatively small overall structure due to their portability. Their drive mainly relies on a long tubular handle to press up and down to achieve the purpose of pipe expanding. The tubular handle is a manual driving mechanism. However, due to the overall length of the tubular handle, it cannot be adjusted, which is inconvenient to carry in practice, and it cannot be adjusted according to people with different arm spans and strengths. Even if some can be adjusted, they are mostly a sleeve with another sleeve on the outside, and then the two are connected by a thread, and the thread is used for adjustment. In actual use, the outer sleeve is easy to rotate, and it is not safe to use. For this reason, we propose a manual driving mechanism for a pipe expanding machine. Utility Model Content

When the movable sleeve 6 is adjusted to a good position, even if the movable sleeve 6 is held by hand to press down, the movable sleeve 6 will not rotate due to the limiting of the limiting sleeve 5 and the rotating sleeve 2, and the movable sleeve 6 is provided in a cylindrical shape, so that it is convenient for the pipe expanding machine staff to grasp, and after the adjustment is completed, the annular handle 14 can be reversed and the annular handle 14 can be retracted. At this time, even if the movable sleeve 6 is held by hand, the rotating round block 13 will not be easily rotated, thereby not changing the position of the movable sleeve 6, and having good safety performance in use.

[0022] The pipe expanding staff selects the pipe expanding machine with the manual drive handle adjustment function, and uses the cooperation of the movable sleeve 6, the rotating sleeve 2 and the adjusting threaded rod 7 to achieve the purpose of adjusting the manual drive handle. It can allow users with small arm spans to shorten its length and people with less strength to increase its length, which is more labor-saving and can also shorten the entire length, making it easier to carry. In addition, the cooperation of the limiting sleeve 5 and the rotating sleeve 2 will not cause the movable sleeve 6 to rotate during use.

[0024] Furthermore, two connecting blocks 3 are fixedly connected to the side of one end of the adjusting sleeve 4 , and the two connecting blocks 3 are symmetrically arranged; the adjusting sleeve 4 is fixedly installed inside the rotating sleeve 2 by using the connecting blocks 3 .

[0025] It should be noted that the cross-sectional profile of the rotating sleeve 2 is set to be a "U" shape, and the internal profile of the limiting sleeve 5 is adapted to the external profile of the rotating sleeve 2; the limiting sleeve 5 can be limited by the rotating sleeve 2, thereby preventing the movable sleeve 6 from rotating easily.

[0026] Furthermore, the outer surface of the movable sleeve 6 is provided with a rubber sleeve, and the outer surface of the rubber sleeve is provided with anti-slip textures; by providing the rubber sleeve, the user's comfort can be improved, and the rubber sleeve can be specifically made of natural rubber.

At this time, the connecting threaded column 8 can still rotate in the fixing ring 16, but cannot move significantly. Subsequently, the slot on the rotating round block 13 is inserted into the rectangular block 11, and then the mounting screw 12 is rotated to connect the mounting screw 12 with the threaded groove, thereby completing the installation of the rotating round block 13, and when the annular handle 14 is retracted, the mounting screw 12 can also be covered, which is also convenient for disassembling the rotating round block 13 in the later stage, thereby replacing the damaged components.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
