[0002] A flat printer is a device that uses ultraviolet curing technology to print. It uses special UV ink and quickly cures the ink on the printing material through an ultraviolet curing system to achieve high-speed and high-precision printing effects. In the Chinese utility model patent with announcement number CN220220144U, a cartridge structure of a UV flat printer is disclosed. The cartridge body is inserted into the bottom slot, and the limit block is inserted into the inside of the limit frame, contacting the inclined surface of the clamping block. The clamping block is squeezed to drive the limit frame to move to the front end, and the spring is compressed until the clamping block corresponds to the groove of the limit block. The spring is released to push the clamping block into the groove of the limit block, so that the ink cartridge assembly is clamped with the mounting seat. In the above structure, multiple ink cartridges are spliced ​​together by sliders and slides, and they are all fixed by the springs and limit blocks below. When installing, multiple pressing rods need to be pressed inward at the same time to enable the ink cartridge to be installed. When disassembling, one of the ink cartridges cannot be disassembled alone. For this reason, we designed a flat printer that is convenient for replacing ink cartridges. Utility Model Content
