[0052] The limiting ring 8 has a groove 801. The limiting ring 8 is arranged on one side of the top surface of the upper seat 502, and the groove 801 is arranged on the side opposite to the protrusion 7;

[0053] The protrusion 7 is inserted into the groove 801, and the bottom surface of the limiting ring 8 is in contact with one side of the top surface of the upper seat 502;

[0054] The cleaning member 9 is adhesively fixed to one side of the inner wall of the limiting ring 8, and the cleaning member 9 is in contact with the outer surface of the rewinding shaft 3;

[0055] The limiting hole 10 is provided on one side of the limiting ring 8;

[0056] The connecting plate 11 has a first connecting hole 111 and a second connecting hole 112. The connecting plate 11 is disposed on one side of the base 5. The first connecting hole 111 and the second connecting hole 112 are disposed on one side of the connecting plate 11.

[0057] The rotating shaft 12 is arranged inside the second connecting hole 112 and the base hole 6;

[0058] The first bolt 13 is provided inside the first connecting hole 111 and the limiting hole 10;

[0059] The connecting plate 11 is movably connected to the base hole 6 through the rotating shaft 12 and the second connecting hole 112 , and the first bolt 13 is threadedly connected to the first connecting hole 111 and the limiting hole 10 .

[0060] Specifically, such as Figure 1-7 As shown, the base 5 is used to install the rewinding shaft 3 on the main machine 2, the upper seat 501 is used to install the rewinding shaft 3, the protrusion 7 and the groove 801 are used to snap the limiting ring 8 to one side of the upper seat 501, the limiting ring 8 is used to install the cleaning member 9, the cleaning member 9 is used to clean the outer surface of the rewinding shaft 3, the base 5 hole and the second connecting hole 112 are used to insert the rotating shaft 12, the rotating shaft 12 is used to movably connect the connecting plate 11 to the base 5 hole, so that the connecting plate 11 can rotate the rotating shaft 12 as the axis, the limiting hole 10 and the first connecting hole 1 11 is used to insert the first bolt 13, and the first bolt 13 is used to thread the connecting plate 11 onto the limiting ring 8. After cleaning, the operator can align the groove 801 on the bottom surface of the limiting ring 8 with the protrusion 7 on the top surface of the upper seat 501 and insert it, and after the upper seat 501 is fitted with the limiting ring 8, rotate the connecting plate 11 upward along the rotating shaft 12 until the first connecting hole 111 is aligned with the limiting hole 10, and then insert the first bolt 13 into the first connecting hole 111 and the limiting hole 10, so that the limiting ring 8 can be fixed on the surface of the upper seat 501.

[0061] The protrusion 7 is cylindrical and has the same size as the groove 801 . The limiting ring 8 is snap-connected to the upper seat 502 via the protrusion 7 and the groove 801 .

[0062] Specifically, such as Figure 1-7 As shown, since the projection 7 and the groove 801 are of the same size, a tight fit is ensured between the connecting parts, reducing looseness or gaps caused by size mismatch. Through the snap connection, the retaining ring 8 can be firmly fixed to the upper seat 502, and is not easy to fall off or loosen, thereby improving the stability of the overall structure.

[0063] The base hole 6 and the second connecting hole 112 have the same size as the rotating shaft 12 . The first connecting hole 111 has a thread built into it, and the first bolt 13 is a hexagon socket bolt.

[0064] Specifically, such as Figure 1-7 As shown, the first connecting hole 111 has a built-in thread, which can be used in conjunction with the first bolt 13 to achieve a more secure connection.

[0065] The limiting ring 8 and the cleaning member 9 are movably connected to one side of the outer surface of the rewinding shaft 3, and the cleaning member 9 is a nylon brush.

[0066] Specifically, such as Figure 1-7 As shown, the nylon bristles have high wear resistance, elasticity and tensile strength, and can better clean surfaces and details. At the same time, the nylon bristles are moderately soft, which can effectively clean while avoiding damage to the cleaning object. The cleaning member 9 is movably connected to the rewinding shaft 3 and can slide left and right along the rewinding shaft to ensure that the target area can be fully covered and deeply cleaned during the cleaning process, thereby improving cleaning efficiency and quality.

[0067] On the other side of the host 2 is provided an observation component 14, which includes:

[0068] A mounting plate 15 having a mounting hole 151, the mounting plate 15 being disposed on the other side of the host 2, and the mounting hole 151 being disposed on one side of the mounting plate 15;

[0069] Mounting slot 16, the mounting slot 16 is provided on one side of the mounting plate 15;

[0070] The window frame 17 has a window hole 171. The window frame 17 is arranged on one side of the mounting groove 16. The window frame 17 is in contact with the mounting plate 15. The window hole 171 is arranged on one side of the window frame 17.

[0071] The mounting groove 16 and the window frame 17 have the same size, the window hole 171 and the mounting hole 151 are arranged at corresponding positions, and the window hole 171 and the mounting hole 151 are arranged parallel to each other;

[0072] Observation window 18, observation window 18 is arranged inside the window frame 17;

[0073] A second bolt 19, which is disposed inside the window hole 171 and the mounting hole 151;

[0074] The window frame 17 is threadedly connected to the mounting hole 151 through the second bolt 19 and the window hole 171 .

[0075] Specifically, such as Figure 1-7 As shown, the mounting plate 15 and the mounting groove 16 are used to install the window frame 17, the window frame 17 is used to set the observation window 18, the observation window 18 is used to allow the operator to portablely observe the internal components of the host 2, the mounting hole 151 and the window hole 171 are used to install the second bolt 19, and the second bolt 19 is used to fix the window frame 17 in the mounting hole 151 on the mounting plate.

[0076] The mounting groove 16 , the window frame 17 and the observation window 18 are arranged in a rectangular shape. The observation window 18 is made of glass and is fixedly connected to the inner wall of the window frame 17 .

[0077] Specifically, such as Figure 1-7 As shown, the rectangular structure has good stability, can withstand greater pressure and tension, and is not prone to deformation. Therefore, the installation groove 16, the window frame 17 and the observation window 18 are arranged in a rectangular shape, which helps to improve the stability of the overall structure.

[0078] The mounting holes 151 are arranged in four groups, and the window holes 171 are arranged in four groups. The mounting holes 151 and the window holes 171 are internally threaded, and the second bolts 19 are cross-hole bolts.

[0079] Specifically, such as Figure 1-7 As shown, the arrangement of four sets of mounting holes 151 and four sets of window holes 171 allows the window frame to be fixed at multiple points, thereby enhancing the stability of the overall structure. This multi-point fixing method effectively distributes the force and reduces deformation or damage caused by excessive force at a single point. The mounting holes 151 and window holes 171 are internally threaded, matching the threads of the second bolt 19, forming a secure threaded connection. This connection is self-locking, resists vibration and loosening, and ensures a tight connection and long-term stability between the components.

[0080] During use: remove the first bolt 13 from the first connecting hole 111 and the limiting hole 10, and then rotate the connecting plate 11 downward with the rotating shaft 12 as the axis, the limiting ring 8 and the upper seat 501 will be disconnected, and then the limiting ring 8 is slid left and right along the rewinding shaft 3, and the groove 801 will also be removed from the outside of the protrusion 7. Since the cleaning member 9 is in contact with the rewinding shaft 3, when the limiting ring 8 slides left and right, the cleaning member 9 will also rub against the outer surface of the rewinding shaft 3, so that the rewinding shaft 3 can be cleaned portablely.

[0081] Through the observation window 18, the use of the internal components can be directly observed, allowing the operator to discover faults and abnormal conditions in a timely manner.

[0082] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
