[0065] A fixing pin 103 is arranged at each corner of the base plate 101, and the fixing pin 103 is used for fixed connection with the base plate fixing hole 305 at the bottom end of the support column 3.

[0066] A test prototype mounting screw hole 105 is arranged at each corner of the base plate 101, and the test prototype mounting screw hole 105 is used for fixing the test prototype 10.

[0067] In the preferred embodiment, a plurality of weight-reducing holes are arranged in an array on the support frame body 201, so as to form a grid structure, which can ensure the strength and reduce the weight, and can indirectly improve the stability by lowering the gravity center as much as possible while improving the operability.

[0068] In use, the nuts are first inserted into the hoisting bolt sliding slots 102 through the nut access slots 106, and the lifting eyes are screwed after being tightened, and then the standard torque can be used. Before use, the installation position and specifications of the lifting belts are determined according to the weight, center position and other parameters of the test prototype 10, and then the lifting eye bolts are installed, and after the position of the lifting eye bolts is determined, the support column 3 is inserted into the position of the fixing pin 103 at the four corners, and is connected through the bolts. Then, the test prototype 10 is installed on the base plate 101, and the test prototype 10 is fixed through the bolts.

[0069] After the base plate assembly 1 and the test prototype 10 are installed, the support legs 203 of the upper support frame 2 are inserted into the hollow column body 301 of the support column 3, the height of the upper support frame 2 is adjusted, and the support legs 203 and the support column 3 are fixed by using the fixing bolts 304.
