The bottom plate 1 mainly provides a quickly replaceable and rotating, sliding base for the gravity clamping mechanism 2, the positioning rod 3 and the flexible support mechanism 4.

[0028] Specifically, the structure of the positioning rod 3 is as shown in Figure 2 The positioning rod 3 and the positioning rod base 5 correspond to each other.

[0030] Specifically, three positioning rod bases 5 (i.e. three positioning rods 3) can be arranged according to the measurement requirements, any one of the three positioning rods 3 can be selected as a positioning reference, the two bolts 50 at the tail of the base can be loosened to adjust the positioning rod 3 in the front-back direction, the adjusting bolt 52 at the quick plug-in opening 51 can be adjusted to adjust the positioning rod 3 in the height direction, and the positioning rod 3 can position the measured part in a vector direction, which is the basis for automatic system measurement of the measured part.

[0033] The outer frame 20 is hollow inside, and the upper end is provided with an opening. The support block 21 and the intermediate movable block 22 are fixedly connected, and the support block 21 extends out of the opening. The left slide block 23 and the right slide block 24 are connected with the intermediate movable block 22 through the inclined slide block 25, and the intermediate movable block 22 drives the left slide block 23 and the right slide block 24 to slide to both sides or to the middle at the same time.
