The positioning pins 5 pass through the through holes 4 and are plugged into the positioning holes 2 opened on the mounting rod 1. The turntable 3 is fixed by the positioning pins 5.

[0033] At the same time, at least three probe fixing mechanisms are distributed in a ring around the mounting head 6. The three probe bodies 8 are fixed in the three probe fixing mechanisms respectively. The probe fixing mechanisms are rotatably connected to the mounting head 6. When the turntable 3 rotates, the use of the probe body 8 can be selected.

[0034] Among them, the probe fixing mechanism includes a fixing sleeve 7, which is rotatably connected to the mounting head 6 through a rotating rod 12. The probe body 8 is inserted in the fixing sleeve 7. Vertical grooves 10 are symmetrically opened inside the fixing sleeve 7, and an annular groove 11 is opened at the end of the vertical groove 10. The annular groove 11 is connected to the vertical groove 10. Since the end of the probe body 8 is symmetrically provided with a protrusion 9, when the probe body 8 is inserted into the fixing sleeve 7, the protrusion 9 slides from the vertical groove 10 into the fixing sleeve 7, and then the protrusion 9 is rotated to move to the annular groove 11, thereby fixing the probe body 8 and installing it in the fixing sleeve 7.

[0035] When using the probe body 8, the rotating rod 12 can be rotated according to the use requirements to rotate the fixed sleeve 7 with the probe body 8. In order to improve the stability of the probe body 8 after rotation, a ratchet 13 is connected to one end of the rotating rod 12, and a pawl 14 is rotatably set on the side wall of the mounting head 6. The ratchet 13 engages with the pawl 14. At the same time, a fixing seat 16 is fixed on the side wall of the mounting head 6. The fixing seat 16 and the pawl 14 are connected by a spring 15. When the rotating rod 12 rotates, due to the clear mechanical engagement relationship between the ratchet 13 and the pawl 14, a very stable rotation action can be provided, thereby improving the reliability and safety of the entire device.

[0036] In order to facilitate the rotation of the rotating rod 12 , a knob with a groove is provided at the end of the rotating rod 12 .

[0037] On the other hand, the present application also provides a probe holder for a test probe, including a needle holder 18, an extension sleeve 19 is provided on one side of the needle holder 18, the mounting rod 1 is inserted into the extension sleeve 19, and an annular plate is provided on the mounting rod 1, and a plurality of mounting holes are provided on the annular plate. The bolt 17 provided on the outside of the extension sleeve 19 is removed, and the annular plate and the extension sleeve 19 are connected using the bolt 17, so that the two form a whole.

[0038] In summary, the working principle of a test probe and a probe holder in an embodiment of the present invention is: the mounting rod 1 is inserted into the extension sleeve 19 to fix the mounting rod 1. At this time, the use of the probe body 8 can be selected by rotating the turntable 3, and the rotation of the rotating rod 12 can adjust the angle of use of the probe body 8. At the same time, the engagement of the ratchet 13 and the pawl 14 is used to improve the stability of the probe body 8, and the positioning pin 5 is used to fix the turntable 3.
