[0022] The above solution is adopted: by setting the clamping assembly 7, the two clamping blocks 701 can be moved to the inside of the connecting plate 5 through the cavity 6, and the use of the two return springs 703 can make the long rod 702, the moving block 704 and the two clamping blocks 701 automatically rebound to their original positions after moving.

[0023] refer to Figure 3 and Figure 4 The movable component 8 includes a pull rod 801, an elastic spring 802, a matching block 803 and a cylinder 804. The surfaces of the pull rod 801, the matching block 803 and the cylinder 804 are all movably connected to the inside of the cavity 6.

During the movement, the cylinder 804 will squeeze the movable hole to make the moving block 704 move forward and make the long rod 702 and the two clamping blocks 701 move forward, so that the two clamping blocks 701 can be moved out of the inside of the connecting plate 5, so that the base 2 can drive the three-dimensional measurement fixture body 1 to move upward and disengage from the mounting plate 3, and the pull rod 801 will make the elastic The force spring 802 generates a deformation force. After the pull rod 801 is released, the elastic spring 802 will give the pull rod 801 the same force, so that the pull rod 801 drives the matching block 803 and the cylinder 804 to rebound to their original positions.
