One end of the spring 402d is fixed on the inner side wall of the fixed frame 401, and the other end is fixed on the trapezoidal block 402c. The spring 402d is a compression spring. The arc surface of the slider 403a cooperates with the inclined side of the trapezoidal block 402c. The third cylinder 403b cooperates with the slider 403a and can rotate in the third groove 403a-1. The third cylinder 403b passes through the threaded hole of the fourth hole 401b-1 and the threaded hole of the seventh hole 104 and is then fixedly connected with the handle 403c. The handle 403c is provided with a third boss 403c-1 and a fifth groove 403c-2. The third boss 403c-1 prevents the handle 403c from contacting the base 100. The fifth groove 403c-2 increases the contact area between the handle and the hand.

[0056] During use, to prevent multipath effects, the adaptive GNSS foundation pier protective cover should be uniformly painted black paint. The diameter of the elastic waterproof gasket 500 should be slightly smaller than that of the foundation pier. First, put the protective cover 200 assembled with the base 100 on the foundation pier, make the base 100 contact with the roof, adjust the opening size of the protective cover 200, put the fixed cover 300 on the foundation pier and then insert it into the protective cover 200, reduce the opening of the protective cover 200, make the top end of the protection piece 201 abut against the outer wall of the small ring of the fixed cover 300, press down the fixed cover 300 until it cannot be pressed any further to complete. Then put the elastic waterproof gasket 500 on the foundation pier and place it downward to the position where it cooperates with the fixed cover 300. Then rotate the handle 403c. The third cylinder 403b pushes the slider 403a to move upward, making the trapezoidal block 402c move horizontally, causing the clamping block 402b to clamp the foundation pier.
