Then, the pressing block is placed on the part and the limiting post is inserted into the fixed hole. It is ensured that the clamping block matches the limiting groove. The threaded post enters the threaded hole. The rotating post is rotated, and the threaded post enters the threaded hole with the rotation. The pressing block is fixed at the top of the fixed base, realizing the clamping of the part and fixing the part. This prevents the part from shifting during the test, which would affect the test results and reduce the test efficiency.

[0030] 2. In this utility model, the base plate is placed on the working surface, pressed down, and the fixed plate is pulled, which drives the connecting plate and the sliding plate to slide down, extracting the air from the hollow box and forming a vacuum. Atmospheric pressure presses the base plate tightly against the working surface. After the fixed plate passes the triangular block, the spring pops out and the triangular block locks the fixed plate to prevent it from sliding down. After the test is completed, the fixed column is pulled to release the limit, thus fixing the base plate. No screws are used for fixing, which reduces damage to the working surface and extends the service life of the equipment. Attached Figure Description
