The lower end of each spring 8 is in abutment against the floating seat 4 on the corresponding side, and the upper end of each spring 8 is in abutment against the moving seat 3. A limit plate 9 is fixed to the lower end of the moving seat 3. The limit plate 9 is used to abut against the lower ends of the two floating seats 4 to prevent the two floating seats 4 from vertically separating from the moving seat 3. Two displacement sensors 5 are fixed on the moving seat 3, and the upper ends of the two probes 6 are respectively connected to the detection end of one of the displacement sensors 5. The two displacement sensors 5 are electrically connected to the controller, and a display screen is provided on the controller.

During the downward movement of the probe, the lower end of the probe can abut against the upper end of the part at the corresponding position. During the continuous downward movement of the movable seat, the floating seat can move upward relative to the movable seat, and the spring can be compressed. At the same time, the detection end of the displacement sensor can be pushed and contracted by the upper end of the probe. After the movable seat moves downward into position, the two displacement sensors can measure the height of the part at the corresponding position (the controller can convert the displacement of the detection end of the displacement sensor into a height value of the part), and the controller can display the height value of the part on the display screen on the controller, so that the staff can judge whether the height of the part is qualified according to the height value displayed on the controller, thereby realizing the detection of the height of the part; when the driving unit drives the movable seat to move upward, the spring can drive the floating seat and the probe to move downward relative to the movable seat.
