[0035] Working principle: When the stethoscope needs to be stored and organized, the operator first gradually winds the sound guide tube 4 on the outer sleeve 204. When the outer sleeve 204 is completely wrapped with the sound guide tube 4, the operator pulls the movable plate 207. The movable plate 207 moves to drive the telescopic rod 205 and the spring 206 to stretch, so that the inner sleeve 208 moves inside the outer sleeve 204. When the telescopic rod 205 is stretched to the maximum limit, the remaining unwound sound guide tube 4 can be wound on the inner sleeve 208, and the threaded rod 213 is rotated to make the threaded rod 213 The threaded rod 213 moves inside the internal threaded ring 214, and by driving the connecting block 212 and the limit block 217 to move, the ring 211 drives the clamping plate 210 to clamp and fix the sound guide tube 4 wrapped around the inner sleeve 208, preventing the sound guide tube 4 from escaping from the outside of the inner sleeve 208. Through the fixing device 2, the problem of a traditional foldable storage stethoscope is solved. Since the sound guide tube 4 at the head end of the stethoscope is relatively long, it is inconvenient to store and organize the stethoscope after use, and it is inconvenient to carry and will occupy most of the space in a medical box or other storage place.

[0036] Through the mobile device 3, when the staff needs to carry the stethoscope conveniently, the operator first installs the support block 31 on the stethoscope, and pulls the clamping plate 33 in the direction away from the support block 31. The clamping plate 33 drives the elastic sheet 32 ​​and the retractable rod 34 to stretch during the movement. When a certain distance is left between the support block 31 and the clamping plate 33, the clamping plate 33 is placed on the inner side of the purse pocket, and the pulled clamping plate 33 is released. The elastic sheet 32 ​​contracts and drives the clamping plate 33 to move toward the support block 31, so that the stethoscope is placed between the clamping plate 33 of the purse pocket and the support block 31. Through the mobile device 3, the problem of the traditional foldable storage stethoscope being inconvenient for the staff to carry the stethoscope due to the lack of an assembled clamping component is solved.
