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

[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a head electrotherapy device, including a support frame 1, a plurality of fixed boxes 2 are fixedly connected to one side of the outer wall of the support frame 1, a stabilizing box 3 is fixedly connected to one side of the outer wall of the plurality of fixed boxes 2, a gear 4 is rotatably connected inside the stabilizing box 3, a knob 5 is fixedly connected to the upper surface of the gear 4, a limit plate 6 is slidably connected inside the fixed box 2, a rack plate 7 is fixedly connected to one side of the outer wall of the limit plate 6, the rack plate 7 is meshed with the gear 4, a handle 8 is slidably connected inside the fixed box 2, a block 9 is fixedly connected to one side of the handle 8, and a spring 10 is sleeved on the outer wall of the handle 8, A protective block 11 is fixedly connected to the inner wall of the fixed box 2, a bracket 12 is fixedly connected to the upper surface of the fixed box 2, a screw rod 13 is threadedly connected inside the bracket 12, a stabilizing block 14 is rotatably connected to the lower surface of the screw rod 13, a limiting top 15 is fixedly connected to the lower surface of the stabilizing block 14, and a limiting assembly 16 is arranged on the outer wall of the stabilizing block 14; the limiting assembly 16 includes a limiting plate 1601, one side of the outer wall of the limiting plate 1601 is fixedly connected to the outer wall of the stabilizing block 14, a limiting rod 1602 is fixedly connected to the upper surface of the limiting plate 1601, and the limiting rod 1602 is slidably connected to the inside of the bracket 12;

[0025] Specifically, by rotating the knob 5, the knob 5 will drive the gear 4 to mesh and rotate with the rack plate 7. This rotation method realizes the sliding adjustment of the rack plate 7, so that the electrode sheet can be accurately adjusted according to the patient's head circumference. After this step is completed, the reaction force of the spring 10 will push the block 9 to engage with the outer wall of the rack plate 7, thereby ensuring the stability of the electrode sheet. On the basis of achieving stability, we can also further optimize. By rotating the screw rod 13, the screw rod 13 will drive the limiting top 15 to contact the electrode sheet on the top of the patient's head. This method further improves the stability of the electrode sheet, making it difficult to move during the treatment process. The design of the limiting top 15 does not exist independently, but is limited and slid by the cooperation of the limiting plate 2 1601 and the limiting rod 1602. This design allows the limiting top 15 to slide freely within an appropriate range, which not only ensures stability, but also avoids the discomfort caused by excessive restrictions.

[0026] Reference Figure 1 , Figure 4 and Figure 5 A sliding sleeve 17 is fixedly connected to one side of the outer wall of the support frame 1, and a back plate 20 is slidably connected inside the sliding sleeve 17; a bolt 18 is fixedly connected to the inner wall of the sliding sleeve 17, and a nut 19 is threadedly connected to the outer wall of the bolt 18; a left-right symmetrical adjusting belt 21 is rotatably connected to the lower side of the outer wall of the back plate 20, and a male and female buckle 22 is provided on one side of the adjusting belt 21; an adjusting belt 23 is fixedly connected to one side of the outer wall of the male and female buckle 22, and a protective block 24 is rotatably connected to one side of the outer wall of the adjusting belt 23; an adjusting strap 26 is rotatably connected to the upper side of the outer wall of the back plate 20, and a plurality of positioning blocks 27 are fixedly connected to the outer wall of the adjusting strap 26; a left-right symmetrical connecting ring 25 is fixedly connected to the upper surface of the protective block 24, and the connecting ring 25 is slidably connected to the adjusting strap 26;

[0027] Specifically, the adjustment strap 26 is passed through the patient's shoulders so that the device can be stably fixed on the patient. Then, the back plate 20 is placed close to the patient's back so that it is in full contact with the back, thereby providing good support. Then, the protective block 24 is placed on the patient's abdomen to protect the abdomen from external collision or friction. (It should be noted that the protective block 11 and the protective block 24 are both made of soft medical silicone) Next, one side of the adjustment belt 23 is engaged with the snap 22 to achieve the connection of the adjustment belt 1 21. At this time, the multiple positioning blocks 27 on the outer wall of the adjustment strap 26 come into play, and they allow the device to be accurately adjusted according to the patient's use requirements. In addition, in order to facilitate adjustment according to the patient's height, first, twist the nut 19 to loosen it, and then pull the sliding sleeve 17 on the outer wall of the support frame 1 to slide. When the appropriate length is reached, tighten the nut 19 to fix it. In this way, the purpose of adjusting according to the patient's height can be easily achieved.

[0028] Working principle: when the patient's head needs to be treated with electrotherapy, first, the adjustment strap 26 is passed through the patient's shoulders, the back plate 20 is pressed against the patient's back, and the protective block 24 is pressed against the patient's abdomen, and then the snap buckle 22 on one side of the adjustment strap 23 is engaged, thereby achieving the connection with the adjustment strap 1 21. At this time, the multiple positioning blocks 27 on the outer wall of the adjustment strap 26 are adjusted to achieve the effect of being easy to adjust according to the patient's use needs; then, the nut 19 is loosened by twisting it, and the sliding sleeve 17 on the outer wall of the support frame 1 is pulled to slide, and the nut 19 is tightened at the same time, thereby achieving the effect of being easy to adjust according to the patient's height;

[0029] Secondly, when the patient is wearing it stably, the knob 5 is turned to drive the gear 4 to engage and rotate with the rack plate 7, thereby achieving the effect of driving the rack plate 7 to slide and adjust. After the adjustment is completed according to the patient's head circumference, the reaction force of the spring 10 pushes the block 9 to engage with the outer wall of the rack plate 7, thereby achieving the effect of stabilizing the electrode sheet. At this time, the screw rod 13 is rotated to drive the limit top 15 to contact the electrode sheet on the top of the patient's head, thereby achieving the effect of further stabilizing the electrode sheet. The limit top 15 is limited and slid by the cooperation of the limit plate 2 1601 and the limit rod 1602.

[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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
