[0003] However, when using the nasal plug electrode rod fixing device, sometimes the fixing position of the electrode rod fixing device is difficult to adjust because the user's nostril position is different. This results in the need to replace different models of fixing devices, wasting the user's time and making it inconvenient to use. Utility Model Content

[0005] This utility model is achieved by the following technical solution: a nasal insertion electrode rod fixing device, including an adjustment mechanism, a fixing mechanism and a base mechanism, wherein the adjustment mechanism is located at the upper end of the base mechanism and the fixing mechanism is located at the upper end of the adjustment mechanism;

[0006] The adjustment mechanism includes a first sliding frame, a first slider slidably connected to the inner wall of the first sliding frame, a limit screw fixedly connected to the inner wall of the first slider, a limit sleeve threadedly connected to the surface of the limit screw, a first snap-fit ​​bracket fixedly connected to the side end of the first slider, a connecting plate fixedly connected to the surface of the first snap-fit ​​bracket, a second snap-fit ​​bracket fixedly connected to the surface of the connecting plate, a second slider fixedly connected to the surface of the second snap-fit ​​bracket, and a second sliding frame slidably connected to the surface of the second slider.

[0007] The above technical solution, which uses a rotating limiting sleeve to control the clamping force between the limiting sleeve and the first snap-fit ​​bracket on the first sliding bracket, achieves the purpose of conveniently adjusting the position of the connecting plate, making the subsequent use of the device more convenient.

[0009] As a further improvement to the above solution, the fixing mechanism includes a mounting frame, a telescopic rod rotatably connected to the inner wall of the mounting frame, a rotating shaft rotatably connected to the inner wall of the mounting frame, a fixing frame fixedly connected to the end of the rotating shaft, a connecting frame fixedly connected to the output end of the telescopic rod, a fixing screw rotatably connected to the inner wall of the fixing frame, a limiting toothed sleeve fixedly connected to the surface of the mounting frame, and a limiting gear fixedly connected to the surface of the rotating shaft.

[0010] The above technical solution utilizes the design of rotating the fixing frame and connecting frame and rotating the fixing screw to bring them together, thus achieving the function of fixing the electrode rod after the angle is adjusted, thereby improving practicality.

[0011] As a further improvement to the above solution, the surface of the limiting gear is engaged with the inner wall of the limiting sleeve, and the surface of the fixing screw is threadedly connected to the inner wall of the connecting frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model, through the setting of an adjustment mechanism, specifically: firstly, the limiting sleeve is rotated to loosen the clamping force between the limiting sleeve and the first snap-fit ​​bracket on the first sliding bracket, thereby releasing the restriction on the connecting plate. Then, the connecting plates at both ends can be pulled to adjust their positions. After the adjustment is completed, the limiting sleeve is tightened again to fix the position of the connecting plate. The design of using the rotation of the limiting sleeve to control the clamping force between the limiting sleeve and the first snap-fit ​​bracket on the first sliding bracket achieves the purpose of conveniently adjusting the position of the connecting plate, making the subsequent use of the device more convenient.

[0018] This utility model employs a fixing mechanism: after the device is fixed, the limiting gear is pulled out to release the rotation limit on the rotating shaft. Then, the angle between the fixing frame and the connecting frame is adjusted according to the user's nostrils. After adjustment, the limiting gear is reinserted to fix the angle of the rotating shaft again. At this point, the electrode rod is inserted into the nostril through the middle of the fixing frame and the connecting frame. After the electrode rod is inserted, the fixing screws at both ends are rotated to bring the connecting frame and the fixing frame closer together, thereby clamping and fixing the electrode rod. The design of using the rotation of the fixing frame and the connecting frame and rotating the fixing screws to bring them closer together achieves the function of fixing the electrode rod after the angle is adjusted, improving practicality.

[0028] Please combine Figure 1-5The nasal insertion electrode rod fixing device of this embodiment includes an adjustment mechanism 1, a fixing mechanism 2 and a base mechanism 3. The adjustment mechanism 1 is located at the upper end of the base mechanism 3, and the fixing mechanism 2 is located at the upper end of the adjustment mechanism 1.

[0029] The adjustment mechanism 1 includes a first sliding frame 101, a first slider 102 slidably connected to the inner wall of the first sliding frame 101, a limiting screw 103 fixedly connected to the inner wall of the first slider 102, a limiting sleeve 104 threadedly connected to the surface of the limiting screw 103, a first snap-fit ​​bracket 105 fixedly connected to the side end of the first slider 102, a connecting plate 106 fixedly connected to the surface of the first snap-fit ​​bracket 105, a second snap-fit ​​bracket 107 fixedly connected to the surface of the connecting plate 106, a second slider 108 fixedly connected to the surface of the second snap-fit ​​bracket 107, and a second sliding frame 109 slidably connected to the surface of the second slider 108. The design of using the rotating limiting sleeve 104 to control the clamping force between the limiting sleeve 104 and the first snap-fit ​​bracket 105 on the first sliding frame 101 achieves the purpose of conveniently adjusting the position of the connecting plate 106, making the subsequent use of the device more convenient.

[0030] The front end of the limiting sleeve 104 is engaged with the rear end of the first sliding frame 101, and the connecting plate 106 is located between the second engaging frame 107 and the first engaging frame 105.

[0031] The fixing mechanism 2 includes a mounting frame 201. A telescopic rod 202 is rotatably connected to the inner wall of the mounting frame 201. A rotating shaft 203 is rotatably connected to the inner wall of the mounting frame 201. A fixing frame 204 is fixedly connected to the end of the rotating shaft 203. A connecting frame 205 is fixedly connected to the output end of the telescopic rod 202. A fixing screw 206 is rotatably connected to the inner wall of the fixing frame 204. A limiting toothed sleeve 207 is fixedly connected to the surface of the mounting frame 201. A limiting gear 208 is fixedly connected to the surface of the rotating shaft 203. The design of using the rotation of the fixing frame 204 and the connecting frame 205 and the rotation of the fixing screw 206 to bring them together realizes the function of fixing the electrode rod after the angle is adjusted, thus improving practicality.

[0032] The surface of the limiting gear 208 is engaged with the inner wall of the limiting sleeve 207, and the surface of the fixing screw 206 is threadedly connected to the inner wall of the connecting frame 205.

[0033] The base mechanism 3 includes a fixed base 301, with strap brackets 302 fixedly connected to both sides of the fixed base 301. A through groove 303 is provided in the middle of the fixed base 301. The design of fixing the fixed base 301 to the user's face by passing the strap brackets 302 through the straps makes the device more stable during use.

[0034] The upper end of the fixed base 301 is fixedly connected to the lower end of the first sliding frame 101, and the upper end of the fixed base 301 is fixedly connected to the lower end of the second sliding frame 109.

[0035] The inner wall of the connecting plate 106 is fixedly connected to the surface of the mounting bracket 201.

[0036] The implementation principle of the nasal insertion electrode rod fixing device in this embodiment is as follows: When using the device, the device is first adjusted according to the position of the user's nostrils. Specifically, the limiting sleeve 104 is rotated to loosen the clamping of the limiting sleeve 104 and the first snap-fit ​​bracket 105 on the first sliding bracket 101, thereby releasing the restriction on the connecting plate 106. Then, the two connecting plates 106 at both ends can be pulled to adjust the position. After the adjustment is completed, the limiting sleeve 104 is tightened again to fix the position of the connecting plate 106. After the nostril position is adjusted, the strap is inserted from the strap bracket 302, and then the device is attached to the user's face. At this time, the nose protrudes from the through groove 303. Finally, the strap is tightened to fix the entire device on the user's face. After the device is fixed, the limiting gear 208 is pulled out to release the restriction on the rotating shaft 20. The rotation limit of the 3rd wheel is then adjusted, and the angle of the fixing frame 204 and the connecting frame 205 is adjusted according to the user's nostrils. After the adjustment is completed, the limiting gear 208 is reinserted to fix the angle of the rotating shaft 203 again. At this time, the electrode rod is inserted into the nostril through the middle of the fixing frame 204 and the connecting frame 205. After the electrode rod is inserted, the fixing screws 206 at both ends are rotated to drive the connecting frame 205 and the fixing frame 204 closer together, thereby clamping and fixing the electrode rod, thus completing the fixing of the electrode rod. The design of using the rotating limiting sleeve 104 to fix the position of the connecting plate 106 and the movement of the connecting frame 205 to clamp the electrode rod realizes the function of fixing the electrode rod while adjusting the device according to the position of the user's nostrils, making the device more comfortable to use and improving the overall practicality.
