[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: an assembled building frame connector, including an installation outer wall 2 fixed to the upper end of a first fixing seat 1, and a second fixing seat 4 fixed to the inner side of the installation outer wall 2. A first installation hole 8 is opened in the inner side of the second fixing seat 4, and a first installation bolt 3 is installed in the inner side of the first installation hole 8. A limiting strip 9 fixed in the installation outer wall 2 is arranged on the outer side of the first installation bolt 3, and a second installation hole 10 is opened in the inner side of the limiting strip 9. A second installation bolt 11 is installed on the outer side of the first fixing seat 1. A third fixing seat 5 is installed inside the first fixing seat 1, and a third installation bolt 12 is installed on the outer side of the third fixing seat 5. A long installation hole 13 opened in the installation outer wall 2 is arranged on the outer side of the third installation bolt 12. A support seat 7 is arranged on the lower side of the third fixing seat 5, and a limiting spring 6 installed in the installation outer wall 2 is arranged at the inner end of the support seat 7;

[0025] When using this device, specifically as in Figure 1 , Figure 2 and Figure 4 , due to the first installation holes 8 being equidistantly opened in the inner side of the second fixing seat 4, the inner side of the second fixing seat 4 having a groove-like structure, the limiting strip 9 being slidably connected to the groove-like structure opened in the inner side of the second fixing seat 4, and the second installation holes 10 being equidistantly opened in the inner side of the limiting strip 9 for installing the first installation bolt 3, the second fixing seat 4 can extend outwards to adapt to dimensional deviations within an appropriate size for installation. Subsequently, the first installation bolt 3 is passed through the first installation hole 8 and the second installation hole 10 for bolt installation. At the same time, the third fixing seat 5 can be extended for fitting installation. After installation, as in Figure 1 and Figure 3In it, the support base 7 is elastically connected to the installation outer wall 2 through the limit spring 6, and a groove-like structure is provided on the upper side of the installation outer wall 2 for the sliding of the third fixing base 5, so that the threaded connection between the third fixing base 5 and the third installation bolt 12 can be resisted by the support base 7 to perform a certain tight connection, strengthening the tightness of the bolt connection. Moreover, the length of the third installation bolt 12 can simultaneously penetrate through the long installation hole 13 and the single-sided hole-like structure of the third fixing base 5, and the third installation bolt 12 is threadedly connected to the long installation hole 13, so that the long installation hole 13 can be installed on the beam-column to increase the fixing effect.
