[0027] The surface of the limit rod 22 is sleeved with a limit spring 20, one end of the limit spring 20 is fixedly connected to the fixing 24, and the other end of the limit spring 20 is fixedly connected to the limit plate 4. The bottom of the indexing chuck body 11 is fixedly connected to the base 1, and a mounting block 2 is fixed on the side of the base 1. The mounting block 2 is provided with four groups, and the four groups of mounting blocks 2 are evenly distributed on the side of the base 1. The surface of the mounting block 2 is provided with a mounting hole 3;

[0028] When in use, first, the base 1 is firmly fixed on the mechanical equipment through the mounting hole 3 on the mounting block 2, ensuring that the indexing chuck body 11 is in the correct working position, and then the handle 25 is turned to pull the limit rod 22 out of the slot 23, and the limit rod 22 is kept in the state at this time, and then the grip 7 is manually operated to align the plug plate 16 of the alarm device body 6 with the slot 23 on the limit plate 4, and push it smoothly along the direction of the slot 23, so that the outer wall of the plug plate 16 forms a sliding connection with the inner wall of the slot 23, and at the same time, the guide rod 13 is correspondingly inserted into the guide hole 15, and the side slider 14 is correspondingly slidably connected to the side slide groove 12, thereby providing a guiding and supporting function, and then the handle 25 is released, and under the rebound action of the limit spring 20, the limit rod 22 is automatically inserted into the limit hole 17, so as to realize the limited installation of the alarm device body 6;

After the limit rod 22 is separated from the limit hole 17, the locking state of the alarm device body 6 is released. By operating the handle 7, the alarm device body 6 is translated outward or gently pulled up, so that the side slider 14 slides out along the side slide groove 12 next to the limit plate 4. At the same time, the plug plate 16 is disengaged from the slot 23 and the guide rod 13 is pulled out of the guide hole 15. After completing the above steps, the alarm device body 6 is separated from the dividing chuck body 11, and the disassembly is completed.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, the guide rod 13 is arranged in the inner cavity 5, the bottom of the guide rod 13 is fixedly connected to the indexing chuck body 11, the surface of the guide rod 13 is sleeved with a support spring 19, the end surface of the support spring 19 is fixed with a moving ring 18, one end of the support spring 19 is fixedly connected to the moving ring 18, the other end of the support spring 19 is fixedly connected to the indexing chuck body 11, the moving ring 18 is slidably connected to the wire rod, the moving ring 18 is in a circular ring shape, and a rubber ring is fixed on the surface of the moving ring 18;

[0032] During use, when installing the alarm device body 6, the guide rod 13 slides into the guide hole 15 accordingly, and then the alarm device body 6 contacts the moving ring 18, so that the support spring 19 is compressed and provides a force to the alarm device body 6, and then cooperates with the limit assembly 10 to improve the stability of the alarm device body 6. During the process of disassembling the alarm device body 6, the elastic force provided by the support spring 19 enables the moving ring 18 to flexibly move up and down along the guide rod 13, thereby providing a rebound force to the alarm device body 6, thereby improving the disassembly efficiency of the alarm device body 6. The provision of an i de rubber ring can prevent the moving ring 18 from directly contacting the alarm device body 6, and prevent the moving ring 18 from damaging the alarm device body 6.

[0033] Embodiment 3

[0034] On the basis of the second embodiment, the limiting assembly 10 includes a limiting spring 20, a limiting rod 22, a fixing member 24 and a handle 25. The handle 25 is fixed on the surface of the fixing member 24. The inner surface of the handle 25 is provided with an anti-slip pattern 26. The limiting rod 22 can be inserted into the limiting hole 17.

[0035] During use, the anti-skid grooves 26 can increase friction, prevent the handle 25 from slipping when being moved, and improve the stability of operation.

[0036] When in actual use, first, the base 1 is firmly fixed on the mechanical equipment through the mounting hole 3 on the mounting block 2, ensuring that the indexing chuck body 11 is in the correct working position, and then the handle 25 is turned to pull the limit rod 22 out of the slot 23, and the limit rod 22 is kept in the state at this time, and then the grip 7 is manually operated to align the plug plate 16 of the alarm device body 6 with the slot 23 on the limit plate 4, and push it smoothly along the direction of the slot 23, so that the outer wall of the plug plate 16 forms a sliding connection with the inner wall of the slot 23, and at the same time, the guide rod 13 is correspondingly inserted into the guide hole 15, and the side slide block 14 is correspondingly slidably connected to the side slide groove 12, thereby providing a guiding and supporting function, and then the handle 25 is released, and under the rebound action of the limit spring 20, the limit rod 22 is automatically inserted into the limit hole 17, so as to realize the limited installation of the alarm device body 6;

[0037] When disassembly is required, the limit rod 22 is pulled out of the limit hole 17 by pulling the handle 25 on the fixture 24. After the limit rod 22 is separated from the limit hole 17, the locking state of the alarm device body 6 is released. By operating the handle 7, the alarm device body 6 is translated outward or gently pulled up, so that the side slider 14 slides out along the side slide groove 12 beside the limit plate 4, and the plug plate 16 is disengaged from the slot 23 and the guide rod 13 is pulled out of the guide hole 15. After completing the above steps, the alarm device body 6 is separated from the dividing chuck body 11, and the disassembly is completed. This avoids the problem that most of the traditional dividing chucks are stuck and the alarm device is installed inside the dividing chuck, which is not convenient for disassembly. When the stuck alarm device needs to be inspected and maintained, the operation is cumbersome, thereby reducing the practicality problem.
