Nozzle mounting module and printer chassis

The utility model belongs to the technical field of printers, and particularly relates to a nozzle mounting module and a printer chassis, which solve the problems of poor fixity of a nozzle body and poor practicability of a printer chassis in the prior art. A stainless steel pipe is embedded in the fixing plate, a heat insulation pipe is embedded in the stainless steel pipe, a feeding pipe is jointly embedded in the heat insulation pipe and the shell, a fixing device is embedded in the shell, and a spray head body is fixedly connected to the interior of the fixing device through screws; the feeding pipe is embedded in the spray head body, through the arrangement of structures such as a blind nut and a clamping block, the fixing device can be rapidly disassembled and assembled by pulling and loosening the blind nut, and therefore the spray head bodies of different sizes can be rapidly replaced or the spray head bodies can be conveniently replaced when damaged. 本实用新型属于打印机技术领域，具体涉及一种喷头安装模块及打印机底盘，解决了现有技术中存在喷头本体固定
