The limiting rod 9 is plugged with the mounting block 3 through the extension hole, the through hole and the second plug-in hole, so that the plug-in rod 5 can be fixed inside the mounting block 3 through the limiting rod 9, thereby achieving the purpose of fixing the rack 4.

[0028] A slide bar 10 is fixedly installed inside the mounting rod 6 , and a mounting groove is provided inside the mounting rod 6 . The telescopic spring 7 and the slide bar 10 are fixedly connected to the mounting rod 6 through the mounting groove.

[0029] It should be noted that the locked rotary reset connection coding switch, by installing a fixed component, can remove and replace the rack 4 after the rack 4 is severely worn out, so that the rack 4 can better mesh with the code disk 11, thereby locking the device and improving the practicability and use quality of the device.

[0030] Specifically, when the rack 4 of the locked rotary reset connection coding switch needs to be replaced, the cover plate 16, the circuit board 14 and the code disk 11 are taken out from the base 1 in turn, and then the two T-shaped levers 8 are pushed in opposite directions so that the T-shaped levers 8 slide on the slide rod 10, and the telescopic spring 7 is compressed, driving the limit rod 9 to move synchronously, thereby moving the limit rod 9 out of the mounting block 3 and the plug-in rod 5, and then the rack 4 is pulled out of the mounting block 3, and then the rack 4 is replaced.

[0031] Example 2: Please refer to Figure 1 On the basis of the first embodiment, a moving component is further installed on the base 1, and the moving component includes a code disc 11 slidably connected to the outer side of the rotating rod 2, a tooth block meshing with the rack 4 is installed on the outer side of the code disc 11, and a slider 12 is fixedly installed inside the code disc 11. Slide grooves are provided on both sides of the rotating rod 2. The slider 12 is slidably connected to the rotating rod 2 through the slide grooves, providing guidance for the code disc 11, making the movement and installation of the code disc 11 more convenient.

[0032] Two connecting columns 13 are fixedly installed inside the base 1 . A circuit board 14 is clamped on the top of the two connecting columns 13 . An annular fixing block is installed on the bottom of the circuit board 14 .

[0033] The bottom of the circuit board 14 is slidably connected to a limit block 15, the top of the limit block 15 is provided with an annular moving block, the bottom of the annular fixed block is provided with a sliding groove, the annular moving block is slidably connected to the annular fixed block through the sliding groove, the top of the base 1 is clamped with a cover plate 16, and the top of the rotating rod 2 is sleeved with a torsion column 17.

[0034] It should be noted that the locked rotary reset connection coding switch is easy to separate the code disk 11 and the rotating rod 2 by installing a moving component, which is convenient for replacing the code disk 11, and further convenient for replacing the device when it is worn, thereby improving the use effect of the device.

[0035] Specifically, when the locked rotary reset connection coding switch is in use, the code disk 11 is slidably connected to the rotating rod 2 through the slider 12. When the code disk 11 is disassembled, the circuit board 14 is removed from the base 1, and then the code disk 11 is moved upward, thereby facilitating the removal of the code disk 11 from the rotating rod 2 for replacement.

[0036] The working principle of the above embodiment is:

[0037] (1) When the rack 4 of the rotary reset connection coding switch with lock needs to be replaced, the cover plate 16, the circuit board 14 and the code disk 11 are taken out from the base 1 in sequence, and then the two T-shaped levers 8 are pushed in opposite directions so that the T-shaped levers 8 slide on the slide bar 10, the telescopic spring 7 is compressed, and the limit rod 9 is driven to move synchronously, so that the limit rod 9 is moved out of the mounting block 3 and the plug-in rod 5, and then the rack 4 is pulled out of the mounting block 3, and then the rack 4 is replaced.

[0038] (2) When the rotary reset connection coding switch with lock is used, the code disk 11 is slidably connected to the rotating rod 2 through the slider 12. When the code disk 11 is disassembled, the circuit board 14 is removed from the base 1, and then the code disk 11 is moved upward, thereby facilitating the removal of the code disk 11 from the rotating rod 2 for replacement.
