[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Appendix Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.

[0021] See attached document Figures 1-3 A three-dimensional single-arm measuring instrument with a limiting function includes a single-arm measuring instrument body 1 and a measuring arm 2 mounted on the single-arm measuring instrument body 1. A measuring component is provided at one end of the measuring arm 2, including a measuring head 3 and a probe 4. The probe 4 is fixedly connected to one end of the measuring head 3. An installation component is provided on the measuring arm 2, and the measuring component is connected to the measuring arm 2 through the installation component. A limiting component is provided on the installation component, which includes an installation sleeve 5. The installation sleeve 5 has several L-shaped grooves 6 arranged at equal intervals. Each L-shaped groove 6 has an L-shaped block 7 engaged within it. The L-shaped block 7 is fixedly connected to the periphery of the same probe 4. The size of the L-shaped groove 6 is larger than the size of the L-shaped block 7. In this embodiment, a person can rotate the probe 4 to move the measuring head 3 within the installation sleeve 5, thereby changing the connection relationship between the L-shaped block 7 and the L-shaped groove 6, initially limiting the probe 4 while also facilitating the removal of the measuring head 3 and the probe 4.

[0022] Specifically, the limiting assembly includes several inclined rods 10. The measuring head 3 has several equally spaced insertion holes 8 on its periphery. The mounting sleeve 5 has several equally spaced through holes 9 on its periphery. The inclined rods 10 pass through the through holes 9 and are inserted into the insertion holes 8. A first compression spring 11 is fitted around each inclined rod 10. A connecting ring 12 is fitted around the periphery of the inclined rod 10 and is fixedly connected to the periphery of the inclined rod 10. One end of the first compression spring 11 is fixedly connected to the connecting ring 12, and the other end is fixedly connected to the periphery of the mounting sleeve 5. A fixing ring 13 is fixedly connected to the periphery of the mounting sleeve 5. A second compression spring 14 is provided on one side of the fixing ring 13, and the second compression spring 14 is located away from... A limiting ring 15 is provided on one side of the fixed ring 13. The limiting ring 15 is sleeved on the periphery of the mounting sleeve 5. One end of the second compression spring 14 is fixedly connected to the fixed ring 13, and the other end of the second compression spring 14 is fixedly connected to the limiting ring 15. Several inclined blocks 16 are fixedly connected inside the limiting ring 15 at equal intervals. The inclined surface of the inclined block 16 is in contact with the inclined surface of the corresponding inclined rod 10. In this embodiment, the personnel can move the inclined block 16 by moving the limiting ring 15, thereby changing the limiting relationship between the inclined block 16 and the inclined rod 10. This allows the first compression spring 11 to rebound and drive the inclined rod 10 to move, so that the personnel can change the limiting relationship between the inclined rod 10 and the measuring head 3 according to the usage requirements.

[0023] The working principle and usage process of this utility model are as follows: When personnel need to disassemble and replace the measuring head 3 and probe 4, they move the limiting ring 15 towards the fixing ring 13. The limiting ring 15 compresses the second compression spring 14. At this time, the limiting ring 15 drives the inclined block 16 to move towards the side closer to the fixing ring 13, so that the inclined block 16 cancels the limitation on the inclined rod 10. At this time, the compressed first compression spring 11 rebounds and drives the inclined rod 10 away from the mounting sleeve 5 through the connecting ring 12, so that the inclined rod 10 moves out of the insertion hole 8 and cancels the limitation on the measuring head 3. At this time, the personnel rotate the measuring head 3 and pull the measuring head 3 away from the mounting sleeve 5, so that the L-shaped block 7 can be taken out from the L-shaped groove 6. At this time, the measuring head 3 and probe 4 are taken out for replacement.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
