The manufacturing cost of the connecting corner bracket 200 is low and it is easy to adjust. Furthermore, when manufacturing door bodies of different specifications, it is not necessary to modify the entire door frame mold. Only the length of the profile needs to be adjusted, and then the adjusted profile is connected by the connecting corner bracket 200 to form the door body. Moreover, the connecting corner bracket 200 does not require structural adjustment and has strong versatility. With the above structure, the manufacturing cost can be reduced while setting a concealed handle, and the specifications can be easily adjusted at a low cost.
[0034] Reference Figure 7 In some embodiments of this utility model, the first profile 110 includes a main body 112, a first protrusion 113, and a second protrusion 114.
