The probe is rotatably installed inside the wire hole 202, and the block 203, together with the connecting rod 204 and the ring 205, is fixed below the probe body 102 to form a circular halo structure made of metal. The stud 201 and the block 203 structure connect the probe and the probe. Since the diameter of the ring 205 is slightly larger than that of the probe body 102, when the probe body 102 is about to collide during operation, the circular halo structure will contact the obstacle before the probe body 102, thereby triggering the probe body 103. At this time, the machine tool will immediately stop moving and issue an alarm signal, thus achieving effective protection for the probe body 102.

[0029] In the above embodiments, as a preferred option, the mounting component 3 includes a first protrusion 301 and a second protrusion 302. The bottom of the first protrusion 301 is fixedly connected to the top of the block 203, and the top of the second protrusion 302 is fixedly connected to the bottom of the probe body 102. The first protrusion 301 on the top of the block 203 and the second protrusion 302 on the bottom of the probe body 102 are in contact, and the locking ring 402 is sleeved on its surface to prevent the connection between the probe body 102 and the stud 201 from becoming loose.

The side of the locking clip 401 is fixedly connected to the side of the block 203. The inside of the locking ring 402 is clamped and fixed to the surface of the first protrusion 301 and the second protrusion 302. A locking groove 403 is provided inside the locking ring 402. The inside of the locking groove 403 is engaged and fixed with the side of the locking clip 401. The locking groove 403 inside the locking ring 402 is sleeved and engaged with the locking clip 401 on the side of the block 203.

[0033] In the above embodiments, as a preferred option, the connecting component 7 includes a connecting sleeve 701. The surface of the connecting sleeve 701 slides in conjunction with the interior of the fixing post 501. A slot 702 is provided at the bottom of the connecting sleeve 701. By pushing the connecting sleeve 701 into the interior of the fixing post 501, the gap of the slot 702 at the bottom of the connecting sleeve 701 is reduced, thereby making the interior of the connecting sleeve 701 in close contact with the surface of the probe body 103, so that the fixing of the probe body 103 is more accurate and the stability of the probe body 103 is higher during use.

[0034] All electrical components mentioned in this article are electrically connected to an external main controller, which can be a conventional known device such as a computer for control.

[0035] In this invention, the working steps of the device are as follows:

[0036] 1. The stud 201 is threadedly mounted on the underside of the probe body 102, while the top of the probe body 103 is threadedly mounted on the inside of the thread hole 202. The block 203, together with the connecting rod 204 and the ring 205, is fixed on the underside of the probe body 102 to form a circular halo structure made of metal. The stud 201 and the block 203 structure connect the probe and the probe. The locking groove 403 inside the locking ring 402 is engaged with the locking clip 401 on the side of the block 203. Since the locking ring 402 has broken grooves at both ends, it can be pulled out to make it easier to use. The first protrusion 301 on the top of the block 203 contacts the second protrusion 302 on the bottom of the probe body 102, and the locking ring 402 is fitted on its surface to prevent the connection between the probe body 102 and the stud 201 from loosening.

[0037] 2. The fixing post 501 is installed at the bottom of the block 203, and the probe body 103 passes through the internal through groove 502 of the fixing post 501 to ensure a stable connection. The connecting sleeve 701 is pushed into the interior of the fixing post 501. At this time, the gap of the slot 702 at the bottom of the connecting sleeve 701 is reduced, so that the interior of the connecting sleeve 701 is in close contact with the surface of the probe body 103, so that the fixing of the probe body 103 is more accurate and the stability of the probe body 103 is higher during use. The probe body 102 is fixed below the connector 101, and the probe body 102 works with the probe body 103 to perform stable measurement on the CNC machine tool.

[0038] 3. Since the diameter of the ring 205 is slightly larger than that of the probe body 102, when the probe body 102 is about to collide during operation, the metal circular halo structure will contact the obstacle before the probe body 102, thereby triggering the probe body 103. At this time, the machine tool will immediately stop moving and issue an alarm signal, thereby effectively protecting the probe body 102. Rotate the outer end of the lever 602 so that the lever 602 rotates around the rotating rod 601 inside the connecting groove 503. At this time, the inner end of the lever 602 pushes the connecting sleeve 701 to slide inside the fixed column 501 so that the connecting sleeve 701 is disengaged from the fixed column 501.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
