The wall surface of each plug rod 21 is elastically connected to a plurality of thrust rods 22. The thrust rods 22 are clamped with the connecting seat 10. The positioning shaft 11 forms a columnar structure. The mounting hole 13 is opened on the circumferential surface of the positioning shaft 11. At least three mounting holes 13 are opened on the circumference of the mounting hole 13. The telescopic member 12 includes an elastic telescopic rod but is not limited to an elastic telescopic rod. The inner wall of the mounting hole 13 is provided with a thread. The telescopic member 12 is threadedly connected to the mounting hole 13. The two plug holes 20 on the top surface of the connecting seat 10 are located On the same axis, scale lines are set on both sides of each socket 20, an annular groove is opened on the inner wall of the socket 20, and the end of the thrust rod 22 forms a spherical convex surface. The end of the thrust rod 22 can be stuck in the annular groove to limit the slipping of the plug rod 21. In this scheme, a plurality of telescopic parts 12 are installed on the wall of the two positioning shafts 11. The telescopic parts 12 take elastic telescopic rods as an example. The outer body of the elastic telescopic rod is provided with threads, and the cylinder is threadedly connected to the mounting hole 13. A plurality of telescopic parts 12 of different specifications can be set, that is, different lengths, and the telescopic parts of the walls of the two positioning shafts 11 are different. Parts 12 jointly support the inner wall of the axial hole of the connecting rod to limit the connecting rod. At the same time, the output shaft of the telescopic part 12 contacts the connecting rod, so that the centers of the two axial holes of the connecting rod are located on the same axis. The two axial holes are concentric with the socket 20. The scale lines on both sides of the socket 20 can show the size of the connecting rod axial hole. It has the characteristics of limiting the connecting rod and automatically finding the center of the circle. The detachable telescopic part 12 and the positioning shaft 11 can replace telescopic parts 12 and positioning shafts 11 of different sizes to adapt to the measurement of connecting rods of various specifications within a certain range.

[0024] To further illustrate, a sliding plate is provided on the top surface of the connecting seat 10, and the wall surface of the sliding plate is provided with the same socket 20. By installing a positioning shaft 11 on the sliding plate, the measurement of connecting rods of different lengths can be met to further improve the adaptability. However, the sliding plate and the sliding plate mounting positioning shaft are not shown in the figure.
[0025] like Figure 4 and Figure 5As shown, the connection component also includes a sliding channel 23, and a plurality of sliding channels 23 are provided on the wall surface of the insertion rod 21.

The elastic member is a spring as an example, and the two ends of the spring are respectively fixedly connected with the end of the thrust rod 22 and the inner wall of the insertion rod 21. As the insertion rod 21 is inserted into the insertion hole 20, when the thrust rod 22 is facing the annular groove in the insertion hole 20, the thrust rod 22 is pushed out of the sliding channel by the spring. 23 is inserted into the annular groove to lock the insertion rod 21. The telescopic member 12 takes the elastic telescopic rod as an example. The outer body of the elastic telescopic rod is provided with a thread, and the cylinder is threadedly connected to the mounting hole 13. A plurality of telescopic members 12 of different specifications can be arranged, that is, different lengths.
