The number of the above-mentioned metal connecting seats 3 is three.

The above-mentioned metal connection ring 1 and metal connection seat 3 are made of titanium metal or titanium alloy.

Technical effect of the present invention is:

1. High strength. In the present invention, a metal connection ring and a metal connection seat are firmly arranged on the support plate, so that they are closely combined with the support plate, and the strength of the support device is improved.

2. Good stability and high precision. In the present invention, the metal connection ring and the metal connection seat are well fixed on the support plate by means of glue connection and screw connection, thereby improving the stability and precision of the support device.

3. Light weight. The aluminum honeycomb interlayer and the carbon fiber skin structure are light in weight, and the metal joint of the present invention is made of titanium alloy, which is light in weight.

4. In the present invention, a threaded rod with an exposed end is provided on the outer surface of the metal connecting column, which is convenient for support and hoisting.
