[0026] The mounting plate is provided with a limiting groove 11 and the rear end of the first adjusting plate 64 is provided with a limiting post. During the movement of the first adjusting plate 64, the limiting post on the first adjusting plate 64 moves within the limiting groove 11.

[0027] The moving mechanism 6 includes a first slide 61, a first screw 62, a first drive motor 63, a first adjusting plate 64, a second adjusting plate 65, a second slide 66, a second screw 67, and a second drive motor 68.

[0029] The latching mechanism 9 includes a latching block 91, a protrusion 92, a serration 93, a latching recess 94, a rotating column 95, a pawl 96, a spring 97, and a paddle 98.

[0030] The probe 10 has a locking block 91 at its bottom, a protrusion 92 at its lower part, and several serrations 93 at its upper part. The mounting block 8 has a locking recess 94 inside that mates with the locking block 91.

[0032] During the latching process of probe 10, firstly, the lever 98 is moved to compress spring 97, and then pawl 96 is lifted. At this time, the protrusion 92 at the bottom of latching block 91 is latched into the latching recess 94 inside mounting block 8. Then, the lever 98 is moved again, and spring 97 rebounds. At this time, the tip of pawl 96 is latched into the groove of serration 93, thereby fixing latching block 91 and further fixing probe 10 above latching block 91. This step allows for quick assembly and disassembly of probe 10. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
