The placement groove 315 provides a channel for the insertion of the clamping plate a 312. Its size is adapted to the clamping plate a 312, which can limit the movement direction of the clamping plate a 312 to avoid deviation during adjustment. The inner bottom wall is provided with a plurality of clamping grooves 316 corresponding to different adjustment positions. Through cooperation with the clamping tooth a 313, the clamping grooves 316 realize multi-stage adjustment of the lateral width and accurately adapt to the chest circumference of different patients; The right end of the clamping plate a 312 is externally provided with a limiting spring 317. The limiting spring 317 can continuously pre-tighten the clamping plate a 312, so that the clamping tooth a 313 and the clamping groove 316 remain in the interlocked state, improving the locking stability after adjustment. The other end of the limiting spring 317 is movably connected to the inner top wall of the receiving piece 314. The movable connection mode can adapt to the movement of the clamping plate a 312; The middle part of the right end of the clamping plate a312 is provided with a magnetic attraction piece a318, and the inner top wall of the receiving piece 314 is provided with a magnetic attraction piece b319 corresponding to the position of the magnetic attraction piece a318. When it is necessary to release the clamping plate a312 to adjust the transverse size, the magnetic attraction piece a318 and the magnetic attraction piece b319 generate an adsorption force, which overcomes the elastic force of the limiting spring 317, drives the clamping plate a312 to move to the upper end, makes the clamping tooth a313 disengage from the meshing state of the clamping groove 316, so that the clamping plate a312 can be freely moved to restore the original state or adjusted to a new position, realizing quick unlocking and resetting.

[0021] As shown in Figure 1 , 8 , 9, in this embodiment, the longitudinal adjustment assembly 32 includes a clamping plate b321 provided on the upper end of the lower support frame 4, which is the core moving part of longitudinal adjustment and can drive the lower support frame 4 to move up and down relative to the upper support frame 4, thereby realizing the adjustment of the overall height. The upper end of the clamping plate b321 is provided with a clamping tooth b322, which is uniformly distributed to form a rack structure and can precisely mesh with a transmission gear 325, stably converting the rotary motion of the gear into the linear motion of the clamping plate b321. A receiving groove 323 is provided at the position corresponding to the clamping plate b321 on the upper support frame 4, and the size of the groove of the receiving groove 323 is precisely matched with the cross-sectional size of the clamping plate b321 to provide guidance for the movement of the clamping plate b321 and avoid deviation during adjustment. A knob groove 324 is also provided on the upper side, which provides independent installation space for the transmission gear 325, the knob rod 326 and other components, and its opening design facilitates the direct operation of the knob piece 327 by medical staff. The left side of the knob groove 324 is in communication with the receiving groove 323, and the communication structure allows part of the tooth surface of the transmission gear 325 to extend into the receiving groove 323 to form meshing with the clamping tooth b322 of the clamping plate b321, ensuring the effectiveness of power transmission. The transmission gear 325 is movably placed in the knob groove 324 to ensure flexible rotation of the transmission gear 325 around its own axis and drive the clamping plate b321 to move without jamming. The transmission gear 325 is meshed and connected with the clamping tooth b322, and the angle of rotation of the knob piece 327 can correspond to the movement distance of the clamping plate b321 to realize precise adjustment of the height. The transmission gear 325 is provided with a knob rod 326 on the upper surface and extends through the surface of the support frame 4. The knob rod 326 is fixed in the center of the transmission gear 325 in a rigid connection manner to play a force transmission role, directly transmitting the rotary force of the external knob piece 327 to the transmission gear 325. The end is provided with a knob piece 327, which is designed to prevent slipping to increase the friction force between the hand and the component, so that medical staff can easily rotate without the help of tools.

[0022] As shown in Figure 8 , 9As shown, in this embodiment, the transmission gear 325 is further provided with a jack 3251 on the right side, one end of the jack 3251 can be attached to the tooth groove of the catch b322, and the movement of the catch b322 is limited by applying pressure, which further enhances the locking effect after longitudinal adjustment, prevents relative sliding between the gear and the catch b322 due to patient activity or vibration, and prevents relative sliding between the gear and the catch b322 due to patient activity or vibration. A rotating shaft b3252 is arranged in the middle of the jack 3251, the rotating shaft b3252 movably connects the jack 3251 to the support frame 4, so that the jack 3251 can rotate around the rotating shaft b3252 to realize the switching between the two states of tightening the catch b322 and loosening the catch b322. The upper end penetrates through the surface of the support frame 4 and extends to the end, and a push piece 3253 is arranged at the end. The push piece 3253 increases the force point of operation, and the medical staff can rotate the jack 3251 by gently pushing the push piece 3253 to quickly switch between the locked and unlocked states, which is simple and efficient.

[0023] As shown in the figure, Figure 1 As shown, in this embodiment, the support seat 1 is provided with a clamping ring 11 at each corner of the outer wall, and the four clamping rings 11 are symmetrically distributed to evenly share the tension of the binding belt 12, thereby avoiding deformation or displacement of the support seat 1 due to excessive local stress, and ensuring that the overall force is balanced after the device is worn. The outer wall of the support frame 4 is provided with a binding belt 12, the binding belt 12 is made of elastic and breathable material, which has a certain tensile force to ensure the fixing effect and can improve the comfort of the patient during wearing, thereby avoiding skin heat caused by long-term wearing. The binding belt 12 is wound back and pasted and fixed through the clamping ring 11 at the corresponding position. After the binding belt 12 passes through the clamping ring 11, a stable fixed structure can be formed to prevent the binding belt 12 from falling off during wearing. The fixed mode of winding and pasting is simple to operate, and the patient or medical staff can quickly complete the wearing and disassembly, and the tightness of the pasting can be flexibly adjusted according to the comfort needs of the patient.

[0024] The working principle and use process of the technical solution are as follows: during use, first, the medical staff adjusts the horizontal adjustment assembly 31 according to the chest circumference of the patient: inserts the clamping plate a312 into the placing groove 315 of the receiving part 314, adjusts the horizontal width by engaging the clamping teeth a313 with different clamping grooves 316, and locks the width by magnetic attraction of the magnetic attraction parts a318 and b318 and pre-tightening of the limiting spring 317. This step allows the support frame 4 to adapt to the chest circumference of the patient, ensures the fit of the chest fixing structure, and avoids excessive or tight fixation. Then, according to the chest height or wound height of the patient, rotate the knob 327 of the longitudinal adjustment assembly 32 to drive the transmission gear 325 to rotate, thereby driving the clamping plate b321 to move in the receiving groove 323 to adjust the longitudinal height. After adjustment, rotate the push piece 3253 to tighten the catch b322 with the jack 3251 to achieve locking. This step allows the support frame 4 to accurately correspond to the wound position, improves the pertinence of the fixing effect, and ensures that the wound is stably covered. Then the support seat 1 is attached to the back of the patient, the support frame 4 is attached to the front of the chest of the patient, the strap 12 of the support frame 4 is threaded through the clasp 11 of the support seat 1 and then wound back and attached, and the tightness of the strap 12 is adjusted to the comfort of the patient and the stability of the device, so that the whole device is worn, and the precise action of the cough assisting part on the back lung area and the precise action of the fixing part on the chest wound are ensured; When the patient generates a cough intention or emits a cough sound, the sound sensor 2111 collects the signal through the sound transmission hole 2114 and transmits it to the control chip 2112, the control chip 2112 starts the motor a 215 and the electrode sheet 221, the motor a 215 drives the rotating shaft a 216, the percussion rod 217 and the percussion ball 218 to rotate, the percussion ball 218 periodically hits the transmission plate 214, the transmission plate 214 compresses the return spring 213 to push the percussion plate 212 to move backward to complete the percussion, and the return spring 213 rebounds to reset the percussion plate 212 to form continuous percussion, and at the same time, the electrode sheet 221 outputs mild electric stimulation to assist the contraction of the respiratory muscle, so that the double-effect cough assisting of mechanical percussion and electric stimulation is realized, that is, the sputum is loosened by physical percussion, and the sputum is moved to the large airway by electric stimulation to improve the sputum removal efficiency; After the cough assisting is completed, the control chip 2112 receives the signal of the sound sensor 2111 to close the motor a 215 and the electrode sheet 221, and the percussion plate 212 returns to the initial position under the action of the return spring 213, so that the device returns to the standby state, and the resource consumption or unnecessary stimulation of the patient caused by invalid work is avoided; During the rehabilitation of the patient, the medical staff can adjust the fixed size by repeatedly operating the horizontal and vertical adjustment assembly 32 according to the wound healing condition or the change of the patient's body shape, and can also adjust the frequency of cough assisting and the intensity of electric stimulation through the control chip 2112, so that the adaptability of the device in different rehabilitation stages of the patient is improved, and the fixing effect and the intensity of cough assisting are always matched with the needs of the patient.
