[0001] The utility model relates to the technical field of gas nozzles, in particular to a modularized gas nozzle with a nozzle that is easy to replace. Background Art

[0002] Coal gas is a gas fuel composed of a variety of combustible components and is widely used in people's lives. When in use, a flame is generally emitted by a gas nozzle, which can heat pots and pans. The production of gas nozzles involves multiple fields such as mechanical parts, parts processing, mechanical parts, parts sales, hardware product manufacturing, hardware product wholesale, and hardware product retail.

[0003] Existing gas nozzles are mostly connected by screw connection. When replacing the nozzle, it is necessary to remove the bolts one by one to replace the nozzle. After replacing the new nozzle, the bolts need to be tightened one by one, which is troublesome and reduces the replacement efficiency. If the gas nozzle becomes loose during connection, a gap may appear at the connection between the nozzle and the gas pipe, resulting in gas leakage and reducing safety during use. For this reason, we propose a modular gas nozzle with an easy-to-replace nozzle. Utility Model Content

[0004] The utility model aims to provide a modular gas nozzle with an easily replaceable nozzle, so as to solve the problem in the above-mentioned background technology that the bolts need to be removed one by one to replace the nozzle, which may cause a gap at the connection between the nozzle and the gas pipe.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modular gas nozzle with a nozzle that is easy to replace, comprising a gas pipe and a second connecting plate, the second connecting plate being located on the right side of the gas pipe, the right side wall of the gas pipe being fixedly connected to the first connecting plate, the upper and lower sides of the inner cavity of the first connecting plate being provided with mounting cavities, the top and bottom of the inner cavity of the mounting cavity being movably connected to pressing rods respectively, the pressing rods passing through the inner cavity of the mounting cavity and extending to the outside of the first connecting plate, the end of the pressing rod being fixedly connected to a mounting block, the front and rear side walls of the mounting block being rotatably connected to push rods, and the upper and lower sides of the left and right side walls of the inner cavity of the mounting cavity being fixedly connected to guide rods.
