[0005] One end of the first L-shaped plate is fixedly disposed in the collecting bin, and at least two threaded rods are horizontally disposed at the other end of the first L-shaped plate, each threaded rod is threadedly connected to a nut, and each threaded rod is sleeved with a compression spring;

[0006] A scraper is fixedly arranged at the bottom end of the vertical plate, a through hole is provided at the top end of the vertical plate, the through hole is sleeved on the threaded rod, one side wall of the vertical plate abuts against the compression spring, and the other side wall of the vertical plate abuts against the nut.

[0007] A preferred solution is that it also includes a charging roller, which is rotatably arranged in the housing, and the charging roller is arranged side by side with the photosensitive drum and is in contact with the photosensitive drum.

[0008] A preferred solution is that the feeding structure includes a magnetic roller, which is arranged side by side with the photosensitive drum and is located on one side of the photosensitive drum.

[0009] A preferred solution is that the feeding structure further includes a flexible plate, and the flexible plate is located just above the magnetic roller and in contact with the magnetic roller.

[0010] A preferred solution is that the feeding structure further includes a stirring roller, and the stirring roller is rotatably disposed in the powder bin.

[0011] The beneficial effects of the above scheme are as follows: one end of the first L-shaped plate is fixedly set on the casing, the compression spring is sleeved on it, the perforated sleeve is set on the two threaded rods, the nut is screwed on the threaded rods, and the scraper on the vertical plate is in contact with the photosensitive drum, so that the scraper is in contact with the photosensitive drum. The installation structure of the new scraper is simple, and the efficiency of scraper installation and disassembly is greatly improved through such a structure. The scraper is used to clean the residual powder on the photosensitive drum, and the scraped residual powder falls into the collection bin. BRIEF DESCRIPTION OF THE DRAWINGS
