[0025] The telescopic hinge 1 is formed by connecting a plurality of hinge units end to end in sequence, specifically, it includes a hinge upper piece 3, a hinge lower piece 4, a pivot shaft 5, and a first spacer ring 6. The hinge upper piece 3 and the hinge lower piece 4 are pivotally connected in the middle through the pivot shaft 5.

[0026] like Figure 4As shown, a pivot hole 7 is provided in the middle of the hinge upper piece 3 and the hinge lower piece 4, the pivot shaft 5 passes through the two pivot holes 7 and is rotatably connected, both ends of the hinge upper piece 3 and the hinge lower piece 4 are hinge ends, and the two hinge units are hinged through the hinge ends, so that the entire telescopic hinge 1 can be evenly telescopic. As an improvement, in this embodiment, in order to avoid direct contact between the hinge upper piece 3 and the hinge lower piece 4, a first spacer ring 6 is provided between the two. The first spacer ring 6 is sleeved on the pivot shaft 5 and is located between the hinge upper piece 3 and the hinge lower piece 4; it can not only avoid interference between adjacent hinges, but also increase the distance between the hinge upper piece 3 and the hinge lower piece 4, so that it is easy to clean the dust in the gap between the two.

[0027] Specifically, Figure 4 , 5 As shown, the lower end of the pivot shaft 5 is provided with a first shaft ring 8 with an enlarged diameter, the middle part of the pivot shaft 5 is a shaft neck 9, and the pivot hole 7 is sleeved on the shaft neck 9. Due to the enlarged diameter of the first shaft ring 8, a step is formed, so that the upper hinge piece 3 and the lower hinge piece 4 are limited at their lower ends after being installed. The upper end of the pivot shaft 5 is a shaft head 10, and a first annular groove 11 is provided between the shaft neck 9 and the shaft head 10. A first retaining spring 12 for axially limiting the upper hinge piece 3 and the lower hinge piece 4 is provided in the first annular groove 11. During installation, when the upper hinge piece 3 and the lower hinge piece 4 are sleeved on the shaft neck 9 through the pivot hole 7, the first retaining spring 12 is clamped in the first annular groove 11 to limit the upper hinge piece 3 and the lower hinge piece 4 on both sides, and then the installation is formed. It can be understood that when the upper hinge piece 3 and the lower hinge piece 4 are installed, the first spacing ring 6 is placed between them.

[0028] Furthermore, the two hinge units are connected to each other through a hinge shaft structure 14, and the hinge shaft structure 14 is provided at both ends of the hinge upper piece 3 and the hinge lower piece 4, and the following is formed: Figure 2 The connections shown,

[0029] Specifically, both ends of the hinge upper plate 3 and the hinge lower plate 4 are provided with hinge holes 13. Figure 2 , 6As shown, a hinge shaft structure 14 is provided in the hinge hole 13, and the hinge shaft structure 14 includes a second shaft ring 15, and short shaft rods 16 are respectively provided at both ends of the second shaft ring 15. The short shaft rods 16 are respectively used to rotatably connect and insert into the hinge holes 13 at the ends of the hinge upper plate 3 and the hinge lower plate 4. The upper end of the short shaft rod 16 is connected with an external threaded rod 17, and a locking nut 18 is provided in cooperation with the external threaded rod 17. When the hinge upper plate 3 is installed on the upper side of the short shaft rod 16, the locking nut 18 is screwed on the external threaded rod 17 to form a fixation; the hinge hole 13 is sleeved on the short shaft rod 16 and rotatably connected; the first spacer ring 6 is used to space the middle part of the hinge upper plate 3 and the hinge lower plate 4, and the second shaft ring 15 can be used to space the two ends of the hinge upper plate 3 and the hinge lower plate 4.

[0030] The upper end of the external threaded rod 17 is provided with an insertion rod 19; the insertion rod 19 is used to install and position the reed needle piece 2. Specifically, the reed needle piece 2 is detachably installed on the hinge unit; Figure 3 , 4 As shown, the reed needle piece 2 includes a needle seat 23, a plurality of reed needle bodies 24 are evenly spaced on the upper end surface of the needle seat 23, and both ends of the lower end surface of the needle seat 23 are respectively provided with insertion holes 25, and the insertion holes 25 are matched with the insertion rod 19, and the middle part of the needle seat 23 is the installation part. Figure 5 As shown, the shaft head 10 is provided with a slot 27, and the mounting portion of the reed needle piece 2 is inserted into the slot 27. The shaft head 10 is provided with screw holes 28 on both sides, and the screw holes 28 are screwed with fixing screws 29, and the fixing screws 29 are arranged perpendicular to the surface of the needle seat 23. During installation, the jack 25 is aligned with the insertion rod 19, and the mounting portion is inserted into the slot 27. After being installed downward, the fixing screws 29 are screwed into the screw holes 28 on both sides, and the screws on both sides clamp the needle seat 23. Further, the upper ends of the plurality of reed needle bodies 24 arranged in a straight line form a serrated profile. The warping machine yarn comes from the creel, and the creel has a number of layers. In order to facilitate the search for the incoming yarn position, the creel is made into oblique teeth according to the characteristics of the creel, and the number of oblique teeth corresponds to the number of layers of the creel. Secondly, the creel has multiple hanging cylinder columns from front to back, so it is a periodic oblique tooth arrangement. Because the creel frame is a left-right structure, there is a special middle piece, and the oblique teeth are arranged symmetrically and periodically from the middle piece. Two yarns are placed in the middle of the middle piece, so the gap in the middle piece is larger; it can be understood that both the flat tooth and the oblique tooth structure at the top of the reed needle body 24 are used. If it is necessary to observe the stratification, the oblique tooth reed needle piece is used, and the flat teeth can be used when used for sizing.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
