The invention discloses a toner cartridge universal drive gear, which comprises a gear body, a driving head coupling joint and an insert. An upper end of that gear body is provide with a driving headcoupling joint, and the gear body is provide with a hollow cavity; The drive head coupling joint is coaxial with the gear body and integrally arranged, and the upper end of the drive head coupling joint is provided with a first interface capable of coupling with a drive head; The insert body is movably located in the cavity of the gear body, the insert body is provided with convex strips, and theinsert body is connected with a spring capable of pushing the insert body upward and sliding axially; At that bottom of the first interface, a sliding hole is arrange for guiding the convex strip on the insert body to slide axially, and the convex strip can be convex into the first interface under the action of the spring tension, and the convex strip cooperate with the inner wall of the first interface so as to change the shape of the inner cavity of the first interface to form a second interface which can be coupled with another driving head. The toner cartridge universal drive gear can realize that the same toner cartridge can be adapted to printers with large and small driving heads, thereby improving the applicability of the product and improving the production efficiency.
Description
technical field [0001] The invention belongs to the technical field of toner cartridges, in particular to a universal drive gear for toner cartridges. Background technique [0002] The toner cartridges are equipped with a driving gear at one end, and the driving gear is provided with an integrally formed driving head, which is connected with the driving part in the printer to drive the photosensitive drum, developing roller and other components to rotate. [0003] At present, there are two kinds of driving gears of different sizes and specifications in the laser printing toner cartridges of Brother and Lenovo series on the market, which are suitable for the size of the driving head of the printer. For the same toner cartridge product series, only the driving gear is different, and the rest are basically the same, which can easily cause product confusion. For the user, if the driving gear is wrong, the toner cartridge cannot be used normally, and it also brings inconvenience...
