[0039] Working principle:

[0040] The probe positioning mechanism with a position adjustment slide of the present utility model can conveniently and stably adjust the basic position of the loaded probe, is convenient to operate, has a stable structure, the mechanism is cost-effective and convenient, has a wide range of applications, and is convenient for combination and matching with an external driving arm.

[0041] During use:

[0042] By disassembling or loosening the probe pressing block 17 on the probe support 16 of the probe limiting component 1, the probe is installed into the probe limiting hole 18 reserved between the probe pressing blocks 17 on the probe support 16. Then, the assembly screw screwed on the probe pressing block 17 on the probe support 16 is tightened, and the detection end of the die-cut probe is exposed from the probe limiting hole 18 between the probe support 16 and the probe pressing block 17.

[0043] By adjusting the mounting base 21 of the position-adjusting slide 2 and the front-back adjusting base 24, left-right adjusting base 23, and up-down adjusting base 22, it is used to adjust the position of the probe on the probe defining assembly 1. The front-back adjusting base 24, left-right adjusting base 23, and up-down adjusting base 22 form a manually adjustable slide with a stable structure, and are assembled with peripheral devices through the kidney-shaped holes provided on the mounting base 21. By screwing the screwing depth of the screwing screw three 248 of the front-back adjusting base 24, the pushing height of the screwing screw three 248 pressing against the roller 25 of the driving swing rod two 245 is adjusted. The roller 25 slidably abuts against the guiding inclined surface on the front-back slide 243 on the front-back slide rail 244. By the pressing position of the roller 25, the distance between the front-back slide 243 and the front-back substrate 241 is pushed open. In addition, the effect of a tension spring is achieved through the elastic reset member 247 connected between the front-back slide 243 and the front-back substrate 241, so that the front-back slide 243 slides relative to the front-back substrate 241 along the front-back slide rail 244 and the front-back guide rod 246, achieving the function of the front-back movement of the front-back adjusting base 24.

[0044] By screwing the screwing depth of the screwing screw two 237 on the left-right substrate 231, the swinging amplitude of the screwing screw two 237 pressing against the driving swing rod one 233 is adjusted. Furthermore, the position where the roller 25 rotatably connected to the driving swing rod one 233 slidably abuts against the guiding inclined surface on the left-right slide 234 is driven, and the left-right slide 234 is displaced relative to the left-right substrate 231 on the left-right slide rail 232 and the left-right guide rod 235. The effect of a tension spring is achieved through the left-right elastic reset member 236 connected between the left-right slide 234 and the left-right substrate 231, so that the left-right slide 234 slides relative to the left-right substrate 231 along the front-back slide rail 244 and the front-back guide rod 246, achieving the function of the left-right displacement of the left-right slide 234.

[0045] By screwing the screwing depth of the screwing screw one 224 on the up-down substrate 223, the pressing depth of the screwing screw one 224 pressing against the assembling slide 227 is adjusted. Furthermore, the relative distance between the assembling slide 227 and the up-down substrate 223 is adjusted. Through the up-down elastic reset member 226 elastically arranged between the assembling slide 227 and the up-down substrate 223, the elastic interval between the assembling slide 227 and the up-down substrate 223 is realized. So that the assembling slide 227 slides relative to the up-down substrate 223 along the up-down slide rail 222 and the up-down guide rod 225, achieving the function of the up-down displacement of the assembling slide 227. Embodiment Two
