Description

Technical Field

[0001] The utility model relates to the technical field of glue nozzles, in particular to a glue nozzle shearing and making knife. Background Art

[0002] The glue nozzle used in glue guns, usually called "nozzle" or "glue nozzle", is a component used to control the flow of glue and accurately spray. It has different sizes and shapes and can be replaced as needed. Common glue nozzles include round hole type, flat hole type and slender type, which are suitable for different glue application scenarios.

[0003] Depending on different usage scenarios, it is sometimes necessary to shear or squeeze the nozzle head to change its diameter or shape at the front end to adapt to different usage scenarios. However, the shearing or squeezing of existing nozzle heads is mostly done by manually cutting with handheld scissors or squeezing the handheld nozzle with a suitable tool, which is not only time-consuming and labor-intensive, but may also be impossible to cut or squeeze due to the lack of scissors and other tools at the place where the glue gun is used.

[0007] A shearing knife is fixedly mounted on the bottom of the L-shaped mounting strip.

[0008] As a further technical solution of the utility model, a mounting block is provided at the rear side of the base, the base and the mounting block are integrally formed, and one end of the L-shaped mounting strip is rotatably connected to the mounting block.

[0009] As a further technical solution of the utility model, the base and the front end of the L-shaped mounting strip can be fixed by a fixing ring.

[0010] As a further technical solution of the utility model, a placement groove is provided on the top of the base above the shearing groove, and the placement groove passes through the shearing groove.

[0011] As a further technical solution of the utility model, the placement groove is adapted to the shearing knife, and the placement groove is used for placing the shearing knife.
