step two, manufacturing a positioning hole (6 b) corresponding to the through hole on the fixture positioner (6);
thirdly, a positioning cylindrical surface (3 a) of the smooth hole type shaft sleeve (3) penetrates through a positioning hole (6 b) of the fixture positioner (6), and then the positioning cylindrical surface (3 a) penetrates into an upper port of a through hole of a second transverse industrial aluminum profile (9);
step four, a second cylinder (5 a) of the thread hole type shaft sleeve (5) is inserted into a lower port of a through hole of a second transverse industrial aluminum profile (9);
fifthly, enabling a threaded cylinder (4 c) of a connecting screw (4) to sequentially penetrate through a positioning hole (6 b) of a fixture positioner (6) and a cylindrical through hole (3 b) of a light hole type shaft sleeve (3) from top to bottom, enabling the threaded cylinder (4 c) and a threaded hole (5 c) of a threaded hole type shaft sleeve (5) to be in threaded connection, enabling a second shaft shoulder (5 b) of the threaded hole type shaft sleeve (5) to be pressed against the bottom surface of a second transverse industrial aluminum profile (9) under the threaded connection force, and enabling a first shaft shoulder (3 c) of the light hole type shaft sleeve (3) to be pressed against the top surface of the fixture positioner (6);
and step six, continuously repeating the step three to the step five for a plurality of times, namely fixedly connecting the second transverse industrial aluminum profile (9) and the fixture positioner (6) together, thereby completing the construction of the fixture.
