A moving sleeve 57 is slidingly connected to the third sliding rod 56, and the moving sleeve 57 is fixedly connected with the moving end of the third linear motor 4, so that when the third linear motor 4 drives the measuring point unit to move, the moving sleeve 57 moves synchronously, and the third sliding rod 56 moves synchronously. The two groups of first sliding rods 52 are parallel to the third linear motor 4, and the second sliding rod 54 is parallel to the first linear motor 2, so that the third sliding rod 56 and the moving sleeve 57 can move stably after the first linear motor 2 and the third linear motor 4 are started.

At the same time, the moving block 71 drives the connecting rods 72 to move synchronously when moving left and right under the limiting action of the synchronous plate 77.

[0035] In the embodiment, when the measuring points of the circuit board are measured, the circuit board is placed on the top of the bottom plate 1, and the first linear motor 2, the second linear motor 3 and the third linear motor 4 are started to move away from the position of the adjusting measuring point unit to position the measuring points and the connecting points. At the same time, after the position adjustment of the measuring point unit is completed, the first push rod motor 62 and the second push rod motor 76 are started at the same time. The first push rod motor 62 extrudes the spring 67 after being started, and drives the moving frame 65 to move, and drives the limiting sleeve 66 to move, so that the limiting sleeve 66 is in contact with the third sliding rod 56, thereby preventing the moving sleeve 57 from continuing to slide on the third sliding rod 56, so that the structure is stable. The second push rod motor 76 drives the synchronous plate 77 to move after being started, and drives the two groups of connecting rods 72 to slide in the moving block 71, and drives the clamping blocks 74 to extrude the second sliding rod 54, so that the second sliding block 55 cannot move, thereby further increasing the stability of the structure and ensuring the stability during the measurement. At the same time, the supporting mechanism 5 supports when the measuring point unit moves, preventing the first linear motor 2, the second linear motor 3 and the third linear motor 4 from being excessively worn, prolonging the service life and improving the measurement accuracy.
