[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-3The utility model provides an embodiment: a probe fixing block, including a placement box 1, the left and right sides of the placement box 1 are fixedly connected with handles, first use the handle to place the placement box 1 to a suitable position, the four corners of the bottom end of the placement box 1 are fixedly connected with support seats, the support seats can prevent the bottom of the placement box 1 from directly contacting the ground, and a box cover 2 is provided on the top of the placement box 1. Then the box cover 2 is placed on the top of the placement box 1, and the four corners of the box cover 2 are slidably connected to the inside of the box cover 2. The inside of the connecting tube 3 is slidably connected to a card column 4, and the left and right sides of the card column 4 are fixedly connected with a connecting rod, and the card column 4 is squeezed downward at the same time. The outside of the card column 4 is fixedly connected with a convex plate 5, and the convex plate 5 will move downward with the movement of the card column 4.

[0025] The top of the protruding plate 5 is fixedly connected with a spring 1 6, and the other end of the spring 1 6 is fixedly connected to the top of the connecting tube 3. The bottom of the protruding plate 5 is fixedly connected with a spring 2 7. At this time, the stretched spring 1 6 squeezes the spring 2 7. The other end of the spring 27 is fixedly connected to the bottom of the connecting tube 3. At this time, the spring 1 6 is reset, and the spring 2 7 is no longer compressed to produce a reaction force on the protruding plate 5. The bottom of the card column 4 is fixedly connected with an extension column 8, so that the extension column 8 moves upward. At this time, the extension column 8 moves downward. A limiting component is set on the outside of the extension column 8. The limiting component includes a base 9, two limiting balls 10 and two card slots 11. The top of the base 9 is fixedly connected to the bottom of the extension column 8, and the limiting ball 10 is slidably connected to the outside of the extension column 8.

[0026] When the locking rod 11 is in contact with the bottom of the placement groove 12, the locking rod 4 is released, and the locking rod 4 is put into the placement groove 12 inside the placement box 1 through the connecting rod. The bottom of the base 9 contacts the bottom of the placement groove 12, and the base 9 no longer contacts the placement groove 12. The outer side of the connecting tube 3 is slidably connected to the inner wall of the placement groove 12, and the outer side of the limiting ball 10 is engaged with the inner wall of the placement groove 12. The limiting ball 10 slides out of the slot 11 and engages with the inner wall of the placement groove 12, fixing the connecting tube 3 inside the placement groove 12, thereby fixing the placement box 1 and the box cover 2. The placement box 1 and the box cover 2 can be quickly disassembled and assembled, which is convenient for replacement and maintenance, so as to be reused.

[0027] Reference Figure 1 and Figure 3, a plurality of placement tubes 13 are fixedly connected to the middle part of the box cover 2, and the probe is placed inside the placement tube 13. Special-shaped grooves 14 are opened on the left and right sides of the interior of the placement tube 13. A fixing component is provided inside the special-shaped groove 14, and the fixing component includes a rubber column 15, a spring three 16 and a protrusion 17. At this time, the probe contacts the protrusion 17, and the outside of the rubber column 15 is slidably connected to the inner wall of the special-shaped groove 14. The protrusion 17 is forced to slide inward inside the special-shaped groove 14, and the spring three 16 is sleeved on the outside of the rubber column 15.

[0028] One side of the protrusion 17 is fixedly connected to one side of the rubber column 15, and at the same time, the rubber column 15 will also be forced to slide inward. One end of the spring three 16 is fixedly connected to the outside of the rubber column 15, and the other end of the rubber column 15 is fixedly connected to the inner side of the special-shaped groove 14. At this time, the spring three 16 is compressed, absorbing external force and generating a reaction force on the rubber column 15. The outside of the protrusion 17 is slidably connected to the inside of the special-shaped groove 14, so that the protrusion 17 is in closer contact with the probe, and the probe is fixed inside the placement tube 13, thereby realizing the anti-deflection and fixation of the probe, and can ensure that it remains stable when entering the placement tube 13.

[0029] Working principle: First, use the handle to place the placement box 1 to the appropriate position, then place the box cover 2 on the top of the placement box 1, and then use the connecting rod to place the card column 4 into the placement slot 12 inside the placement box 1, and at the same time squeeze the card column 4 downward. At this time, the convex plate 5 will move downward with the movement of the card column 4. At this time, the tension spring 1 6 squeezes the spring 2 7. At this time, the extension column 8 moves downward. When the base 9 contacts the bottom of the placement slot 12, the card column 4 is released. At this time, the spring 1 6 is reset, and the spring 2 7 is no longer compressed to generate a reaction force on the convex plate 5, so that the extension column 8 moves upward, and the base 9 is no longer in contact with the placement slot 12. When the limit ball 10 is squeezed, it will slide to the outside of the slot 11. When the limit ball 10 slides out of the slot 11, it will engage with the inner wall of the placement slot 12, fixing the connecting tube 3 inside the placement slot 12, thereby fixing the placement box 1 and the box cover 2, and placing the probe inside the placement tube 13. At this time, the probe contacts the protrusion 17, and the protrusion 17 is forced to slide inward inside the special-shaped slot 14. At the same time, the rubber column 15 is also forced to slide inward. At this time, the spring three 16 is compressed, absorbing external force and generating a reaction force on the rubber column 15, so that the protrusion 17 is in closer contact with the probe, and the probe is fixed inside the placement tube 13.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
