[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] See also Figure 2 Combined with Figure 3 , Figure 2 This is a three-dimensional diagram of a preferred embodiment of a swing arm structure for an opening mechanism of the utility model; Figure 3 This is a three-dimensional diagram of the optimal embodiment of the connecting shaft and connecting rod of the utility model. Figures 2 to 3 As shown, at least one embodiment provides a swing arm structure for an opening mechanism, comprising: a connecting rod portion 1 and a coupling portion 2. The connecting rod portion 1 and the coupling portion 2 are designed as separate parts. After the braiding machine has been working continuously for a certain period of time, the coupling portion 2 that has been worn to a certain extent is replaced separately during the maintenance process, and the original connecting rod portion 1 is not disassembled or replaced, which not only reduces the difficulty of operation but also reduces the cost of use. Specifically, the coupling portion 2 is sleeved on the connecting rod portion 1 through a locking member 4, and a protective cover 3 is provided between the locking member 4 and the coupling portion 2.

[0028] Connecting rod 1

[0030] Coupling 2

[0031] Please continue reading Figure 2 Combined with Figure 3 .like Figure 2 and Figure 3 As shown, the coupling 2 comprises a ferrule 21 and a sleeve 22. The ferrule 21 fits over the end of the connecting rod 2. The sleeve 22 and ferrule 21 are integrally formed and connected to the rotating shaft of the opening mechanism. The inner contour of the ferrule 21 matches the outer contour of the top of the connecting rod 1. A locking hole 23 is defined in the ferrule 21, and the inner wall of the locking hole 23 and the inner wall of the mounting hole 11 are both provided with threaded grooves.

[0032] Protective cover 3

[0033] See also Figure 2 Combined with Figure 4 and Figure 5 , Figure 4 A three-dimensional cross-sectional view of a preferred embodiment of the protective cover of the present invention; Figure 5 This is a schematic structural diagram of the optimal embodiment of the back plate of the utility model. Figure 2 、 Figure 4 and Figure 5As shown, the protective cover 3 is made of transparent acrylic material as a whole, which can better observe the position of the rotation gap of the coupling part 2. The protective cover 3 is used to cover the outer periphery of the coupling part 2. In addition, the protective cover plays the role of a spacer, enhancing the stability of the connection between the locking member 4 and the coupling part 2. The components of the protective cover 3 are described in detail below. The protective cover 3 includes a back plate 31, and the back plate 31 has a front surface and a back surface corresponding to the front surface. The front surface faces the outer wall of the ferrule 21 and the sleeve 22. The back surface is provided with a grid-like reinforcing rib. A baffle 32 is provided on the edge of the back plate 31. The baffle 32 around the circle is used to block dust and prevent dust from entering the rotating gap of the coupling part 2. The extension direction of the baffle 32 is perpendicular to one side of the clamping sleeve 21. The bottom surface of the baffle 32 is provided with an open groove 33. The open groove 33 is used to clamp the back plate 31 between the locking piece 4 and the coupling part 2, so as to achieve the overall installation effect of the protective cover 3. The open groove 33 extends to the bottom edge of the back plate 31 and is suitable for being clamped on the threaded rod.

[0034] Locking piece 4

[0035] Please continue reading Figure 2 .like Figure 2 As shown, the locking member 4 includes a threaded rod and a nut.

The threaded rod is screwed into the locking hole 23 and extends to the mounting hole 11. Part of the protective cover 3 is clamped between the nut and the ferrule 21.

[0036] In summary, by setting up a split connecting rod part 1 and a coupling part 2, the difficulty of maintenance is reduced, the utilization rate of the main part of the swing arm structure is improved, and the cost of use is reduced; the protective cover 3 is installed by the locking part 4, which not only enhances the connection stability, but also protects the coupling part 2 to prevent dust from being entangled on the rotating shaft; by setting up the protection 3, the grid reinforcement ribs on the back plate 31 are allowed to rest on the coupling part 2, thereby improving the overall strength of the swing arm structure and reducing the probability of the coupling part 2 being damaged by collision.
