[0002] In the field of construction, the installation of doors and windows is an important link. In order to achieve the fixation and connection of doors and windows, it is usually necessary to use an angle code to splice two profiles to complete the L-shaped connection. In this process, the traditional method is to install a flow guide plate on the surface of the angle code, and then to inject glue by means of impact angle and punching, so that the glue enters the hole site and flows in the groove on the flow guide plate until the glue flows out of the impact angle hole, indicating that the injection of glue is complete. In this way, the profiles and the angle code can be stably connected through the fixing effect of the glue.

[0003] However, the traditional method has a problem, that is, once the flow guide plate falls off between the angle code, it will cause the connection between the two profiles to shake, affecting the stability and service life of the door and window.
