It engages with the positioning concave edge of the inner tube, 'A press button is assembled above the convex column', and a button is used to normally support the button and the slider to support it normally. However, the structure of this telescopic rod still has many problems. Where it ’s ideal, such as: the component of the inner tube positioning block 2 is missing, 3 the inner diameter of the stopper tube and the ground layer are added due to the existence of the product, the card is not fixed, the card is not only to take this, The extension, an inner and outer diameter phase-layer pipe fittings were not designed in an intact way to make a small one, During the pull, the internal tube position structural elements are difficult to obtain, and the assembly of the retracted rod is made up of the tube as a whole. The difference between the four tubes is not large. One by one, in terms of physical necessity, it is necessary The experience of adjusting the length of the tube has a lot of telescopic adjustments, and it is inconvenient to be small and round. It is also composed of I outside and inside. Therefore, it will be considered as a considerable effect when it is assembled. In the research and modification of the tail groove, it is easy to pull more difficult parts when it is more round. It is easier to improve the production of an outer tube, and when it is fitted with each other, it is necessary to produce a product that does not have a practical extension. Necessary, Nara, if you can't withdraw it for a long time, you will suffer. , And the circular cost due to rolling off. It is very labor-intensive and efficient between casing and pipe. Usability, contraction device to work on the idea
