[0027] The two frame vertical rods 2 have a second positioning notch 5 at both ends. The second positioning notch 5 has a second threaded hole 6 inside. The first positioning notch 3 and the second positioning notch 5 are provided with a connector 7 inside. The connector 7 has a fixing bolt 8 passing through it.

[0028] Preferably, the first positioning notch 3 and the second positioning notch 5 have a T-shaped cross section, the connector 7 has an I-shaped cross section, there are two fixing bolts 8, and the two fixing bolts 8 are symmetrically distributed between them. One end of the connector 7 can form a threaded connection structure with the frame crossbar 1 through the first positioning notch 3 and the first threaded hole 4, and one end of the connector 7 can form a threaded connection structure with the frame vertical bar 2 through the second positioning notch 5 and the second threaded hole 6.

[0029] In practical use, by arranging two frame crossbars 1 and two frame vertical bars 2 into a rectangular frame, the two ends of the connector 7 are respectively embedded into the first positioning notch 3 and the second positioning notch 5 at the ends of the frame crossbars 1 and the frame vertical bars 2. Then, the fixing bolt 8 is passed through the connector 7 and connected to the first threaded hole 4 and the second threaded hole 6, so that the assembly and fixing between the frame crossbars 1 and the frame vertical bars 2 can be realized. Thus, the connection strength at the splice of the frame crossbars 1 and the frame vertical bars 2 can be strengthened by the I-shaped connector 7.

[0030] Preferably, the outer walls of the two frame crossbars 1 are provided with limiting grooves 9, and the outer walls of the two frame crossbars 1 are connected with positioning plates 10, the ends of the positioning plates 10 being located inside the limiting grooves 9.

[0031] In practical use, with the setting of the limiting groove 9 and the positioning plate 10, when splicing the frame crossbar 1 and the frame vertical bar 2, the end of the positioning plate 10 will be embedded in the limiting groove 9, thereby playing a positioning role, preventing the frame vertical bar 2 from shaking during assembly and fixing, and facilitating subsequent operations by the staff.
