Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a photosensitive drum that is easy to install and disassemble, including a fixing frame 1, a motor 2 fixedly connected to one side of the fixing frame 1, an installation assembly 3 fixedly connected to the output shaft of the motor 2 via a coupling, a connecting assembly 4 provided on one side of the installation assembly 3, and a photosensitive drum body 5 provided on one side of the connecting assembly 4; the installation assembly 3 includes an installation plate 301, a limiting groove 302 formed on one side of the installation plate 301, a limiting rod 303 fixedly connected inside the limiting groove 302, a spring 304 provided on the outer wall of the limiting rod 303, and a positioning sleeve 30 engaged inside the limiting groove 302. 5. The mounting plate 301 and the positioning sleeve 305 form a locking structure through the limiting groove 302, and the inner diameter of the limiting groove 302 matches the outer diameter of the positioning sleeve 305. The outer wall of the positioning sleeve 305 fits snugly against the inner wall of the limiting groove 302, enhancing the connection between the mounting plate 301 and the positioning sleeve 305. This allows the positioning sleeve 305 to be inserted into the limiting groove 302 for connection with the mounting plate 301. The mounting plate 301 and the positioning sleeve 305 form an elastic structure through the spring 304, and one end of the spring 304 is fixed to the interior of the mounting plate 301. The other end is connected to one side of the positioning sleeve 305, strengthening the connection between the mounting plate 301 and the spring 304. This allows the spring 304 to support the positioning sleeve 305 with the support of the mounting plate 301. A connecting plate 306 is fixedly connected to one side of the positioning sleeve 305. The connecting plate 306 and the positioning sleeve 305 form a fixed structure. There are two positioning sleeves 305, symmetrically arranged about the perpendicular bisector of the connecting plate 306, strengthening the connection between the connecting plate 306 and the positioning sleeve 305. This allows the connecting plate 306 to support the positioning sleeve 305 with the support of the mounting plate 301. The positioning sleeve 305 is fastened in the mounting plate 301 for quick installation. By holding the photosensitive drum body 5, one end of the photosensitive drum body 5 can be inserted into the mounting plate 301 for installation. The positioning sleeve 305 on the photosensitive drum body 5 can be inserted into the limiting groove 302 for fastening and installation. The positioning sleeve 305 can be sleeved on the outer wall of the limiting rod 303 to compress the spring 304. The other end of the positioning sleeve 305 can also be fastened to one side of the mounting plate 301 for fastening and installation. Thus, the photosensitive drum body 5 can be quickly installed and removed.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The connecting component 4 includes a fixing post 401, a side plate 402 fixedly connected to one side of the fixing post 401, a fixing bolt 403 provided inside the side plate 402, and a screw 404 fixedly connected to one side of the fixing post 401. The fixing post 401 and the photosensitive drum body 5 form a threaded structure through the screw 404, and the outer diameter of the screw 404 matches the inner diameter of the screw groove 405, and the outer wall of the screw 404 fits against the inner wall of the screw groove 405, which strengthens the connection effect between the fixing post 401 and the screw 404. This allows the fixing post 401 to be fastened and installed inside the screw groove 405 in the photosensitive drum body 5 by relying on the screw 404, which improves the connection effect between the fixing post 401 and the photosensitive drum body 5. A screw groove 405 and a fixing groove 406 are opened on one side of the photosensitive drum body 5. The side plate 402 is fixedly connected to the photosensitive drum body 5 through the fixing bolt 403. The structure is fixed, with one end of the fixing bolt 403 penetrating through the side plate 402 and fastened in the fixing groove 406 inside the photosensitive drum body 5. This facilitates the installation of the fixing bolt 403, allowing the fixing bolt 403 to install and fix the side plate 402 and the photosensitive drum body 5 together. This improves the connection effect between the photosensitive drum body 5 and the fixing post 401. After the photosensitive drum body 5 is removed and disassembled, the fixing bolt 403 on the side plate 402 can be loosened and disassembled, allowing the fixing bolt 403 to detach from the installation of the side plate 402 and the photosensitive drum body 5. At the same time, rotating the fixing post 401 allows the fixing post 401 to be loosened and disassembled by relying on the screw 404 in the screw groove 405. This allows the fixing post 401 to be disassembled from the photosensitive drum body 5. Therefore, when disassembling and replacing the photosensitive drum body 5, the photosensitive drum can be replaced directly, reducing the waste of auxiliary materials.

[0023] Working principle: During use, by holding the photosensitive drum body 5, one end of the photosensitive drum body 5 can be inserted into the mounting plate 301 for installation. The positioning sleeve 305 on the photosensitive drum body 5 can be inserted into the limiting groove 302 for fastening and installation. The positioning sleeve 305 can be sleeved on the outer wall of the limiting rod 303, compressing the spring 304. The other end of the positioning sleeve 305 can also be fastened to one side of the mounting plate 301 for fastening and installation. This allows for quick installation and removal of the photosensitive drum body 5. Furthermore, after removing and disassembling the photosensitive drum body 5, it can be... Loosening and removing the fixing bolts 403 on the side plate 402 allows the fixing bolts 403 to be detached from the installation of the side plate 402 and the photosensitive drum body 5. At the same time, rotating the fixing post 401 allows the fixing post 401 to be loosened and removed by means of the screw 404 in the screw groove 405. This allows the fixing post 401 to be disassembled from the photosensitive drum body 5. Therefore, when disassembling and replacing the photosensitive drum body 5, the photosensitive drum can be replaced directly, reducing the waste of auxiliary materials. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
