DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , a follow-up bracket for a magnetic stimulator, including a substrate 101 and a neck support 102 fixed on a seat. The substrate 101 is installed on the seat, and a headrest height adjustment mechanism is provided between the substrate 101 and the seat, which can adjust the height of the substrate 101. This headrest height adjustment mechanism is a mature device and will not be elaborated here too much. The neck support 102 is connected to the substrate 101. During use, the neck support 102 is sleeved on the patient's neck, and the head of the patient is treated by the treatment paddle 109 at the top. The top of the substrate 101 is connected with an arc slide rail 103, and a slider 104 is slidably connected to the top of the arc slide rail 103. The neck support 102 slides on the arc slide rail 103 through the slider 104 to adapt to the rotation of the head. The top of the slider 104 is connected with an arc rack 105, the top of the arc rack 105 is connected with a support plate 106, and the neck support 102 is connected to one end of the support plate 106;

[0029] Refer to Figure 2 , at the top of the end of the support plate 106 away from the neck support 102, an adjustable bracket 107 is connected. The top of the adjustable bracket 107 is connected with a connection component 108, and a treatment paddle 109 is installed inside the connection component 108. The treatment paddle 109 is a device for providing magnetic stimulation treatment and is fixed on the support plate 106 through the adjustable bracket 107;

[0030] When the patient rotates the head, it will be relatively difficult to rotate due to the weight of the treatment paddle 109. The following provides a boosting structure: Refer to Figure 2 and Figure 3 , the bottom of the substrate 101 is connected with a driving motor 110, the output end of the driving motor 110 is connected with a torque sensor 111, the torque sensor 111 is in signal connection with the driving motor 110, and the output end of the torque sensor 111 is connected with a driving gear 112 that meshes with the arc rack 105. When the torque sensor 111 detects the rotation of the patient's head through the arc rack 105, the driving motor 110 will be started, so that the output end of the driving motor 110 drives the arc rack 105 to rotate through the driving gear 112, thereby providing a boosting effect on the patient;

[0031] When the assisting structure moves with the patient's head, the patient may turn their head too much, which may cause the arc rack 105 to move beyond its limit. The following provides a structure to prevent the arc rack 105 from moving beyond the stroke of the arc slide rail 103: Refer to Figure 4 , cavities 113 are formed at both ends of the arc rack 105. A moving block 114 is rotatably connected inside the cavity 113. The rotation axis of the moving block 114 is located on the side close to the end of the arc rack 105. One side of the moving block 114 is provided with a tooth surface that cooperates with the tooth surface of the arc rack 105. A spring 115 is used to push the moving block 114 out of the cavity 113, so that the side of the moving block 114 with the tooth surface remains in the same position as the tooth surface of the arc rack 105. The side of the moving block 114 away from the teeth is connected to a spring 115 located inside the cavity 113. A stop block 126 is provided at one end of the cavity 113 close to the rotation axis of the moving block 114. When the arc rack 105 moves to the position where both ends contact the driving gear 112, the moving block 114 will be compressed into the cavity 113, and the driving force during the rotation of the driving gear 112 is offset by the compression of the spring 115 on one side, avoiding the situation of excessive movement of the arc rack 105. When the driving gear 112 rotates in reverse, at this time, the end of the moving block 114 close to the rotation axis will contact the stop block 126, and the stop block 126 blocks the moving block 114, so that the driving force during the rotation of the driving gear 112 can act on the arc rack 105 through the moving block 114, thereby enabling the arc rack 105 to move.

[0032] Specifically, refer to Figure 3 , symmetric limiting blocks 116 are connected to the base plate 101. Although the situation of excessive movement of the arc rack 105 can be avoided by the idling of the driving gear 112 at the position of the moving block 114, there will still be a situation where the patient drives the arc rack 105 to move excessively. Therefore, limiting blocks 116 with a blocking function are provided on both sides of the base plate 101. By blocking the limiting plate 117 with the limiting blocks 116, the situation of the slider 104 moving out of the arc slide rail 103 is prevented. The limiting blocks 116 are located at both ends of the arc slide rail 103. One side of the slider 104 is connected to a limiting plate 117 that contacts the limiting blocks 116. A buffer pad is connected to the side of the limiting block 116 close to the limiting plate 117, and the buffer pad plays a buffering role to avoid the generation of noise when the limiting plate 117 contacts the limiting blocks 116.

[0033] To accommodate patients of different body types, the following provides a structure that can adjust the distance between the neck support 102 and the seat back: Refer to Figure 5, specifically, the support plate 106 includes a sleeve 118 and a sliding frame 119 slidably connected within the sleeve 118. The sliding frame 119 can slide within the sleeve 118, thereby increasing the length of the support plate 106. One end of the sliding frame 119 located inside the sleeve 118 is connected with a fixed rack 120. The fixed rack 120 is provided only on one side of the sleeve 118. When the fixed gear 122 rotates, it can drive the fixed rack 120 to move, thereby pushing the sliding frame 119 out of the sleeve 118. Through the meshing connection between the fixed rack 120 and the fixed gear 122, the length of the support plate 106 is adjusted. A rotating rod 121 penetrating the sleeve 118 is rotatably connected to the sleeve 118. A fixed gear 122 meshing with the fixed rack 120 is connected to the outer wall of the rotating rod 121. The width of the fixed gear 122 is smaller than that of the fixed rack 120. The rotating rod 121 can drive the fixed gear 122 to move up and down, but the fixed gear 122 will not disengage from the fixed rack 120.

[0034] Specifically, referring to Figure 5 , a spline block 123 is connected to the bottom of the rotating rod 121, and a spline bracket 124 cooperating with the spline block 123 is connected to the bottom of the sleeve 118. The spring 115 drives the spline block 123 to move upward, so that the spline block 123 can be inserted into the spline bracket 124. Through the connection between the spline bracket 124 and the spline block 123, a limiting effect is exerted on the rotating rod 121.

[0035] Specifically, referring to Figure 5 , a handle 125 is connected to the top of the rotating rod 121. A spring 115 is provided between the handle 125 and the sleeve 118. The handle 125 at the top facilitates the rotation of the rotating rod 121, thereby driving the fixed gear 122 to rotate.

[0036] In this embodiment, the patient sits on the seat and puts the neck support 102 on the neck. The length of the support plate 106 is adjusted according to the needs of the body shape so that the patient can sit comfortably. Subsequently, the treatment plate 109 is adjusted to the patient's head through the adjustable bracket 107, and then magnetic stimulation treatment is carried out. When the patient rotates the head, the torque sensor 111 will sense the torsion signal, and then drive the arc rack 105 to move through the drive motor 110 to play a boosting role.

[0037] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
