  "abstract": "The present application relates to a panorama stitching camera, including: a base provided with a fixing plate; a main shaft passing vertically through the fixing plate; and a plurality of lenses disposed at one end of the main shaft, wherein, a limiting protrusion and a shaft end retaining ring that abut respectively against two opposite sides of the fixing plate are disposed at the other end of the main shaft. When the angle of view of the panorama stitching camera is being adjusted, the plurality of lenses can rotate around the axis of the main shaft simply by rotation of the main shaft. Thus, the adjustment of the angle of view of the lens along the circumferential direction of the main shaft is achieved, and the operation of adjusting the angle of view of the panorama stitching camera is greatly simplified. Thus, the problem that the angle of view of an existing panorama stitching camera cannot be adjusted readily during use is solved.",
  "claims": [
    "1. A panorama stitching camera, comprising: a base provided with a fixing plate; a main shaft passing vertically through the fixing plate, the main shaft being rotatable around an axis of the main shaft; and a plurality of lenses disposed at one end of the main shaft; wherein, a limiting protrusion and a shaft end retaining ring that abut respectively against two opposite sides of the fixing plate are disposed at the other end of the main shaft, wherein, the shaft end retaining ring comprises an elastic diaphragm that is connected to an end of the main shaft and parallel to the fixing plate, and a convex ring that protrudes toward the fixing plate from one side of the elastic diaphragm and abuts against the fixing plate.",
    "2. The panorama stitching camera of claim 1, wherein, the elastic diaphragm is ring-shaped, and the elastic diaphragm, the main shaft, and the convex ring have the same axis.",
    "3. The panorama stitching camera of claim 2, wherein, the shaft end retaining ring further comprises a sleeve that protrudes from another side of the elastic diaphragm in a direction away from the fixing plate and has the same axis and inner diameter as the convex ring.",
    "4. The panorama stitching camera of claim 3, further comprising a heater disposed at the end of the main shaft at which the lenses are disposed, wherein the heater is configured to heat the plurality of lenses simultaneously.",
    "5. The panorama stitching camera of claim 3, further comprising a fixing frame, a plurality of lens holders disposed on the fixing frame, and a ball core adjustment shaft fixed on the fixing frame, wherein, the ball core adjustment shaft is pivotally connected to the main shaft, and each of the plurality of lenses is mounted on one of the plurality of lens holders.",
    "6. The panorama stitching camera of claim 3, wherein, the elastic diaphragm is a corrugated diaphragm.",
    "7. The panorama stitching camera of claim 2, further comprising a heater disposed at the end of the main shaft at which the lenses are disposed, wherein the heater is configured to heat the plurality of lenses simultaneously.",
    "8. The panorama stitching camera of claim 2, further comprising a fixing frame, a plurality of lens holders disposed on the fixing frame, and a ball core adjustment shaft fixed on the fixing frame, wherein, the ball core adjustment shaft is pivotally connected to the main shaft, and each of the plurality of lenses is mounted on one of the plurality of lens holders.",
    "9. The panorama stitching camera of claim 2, wherein, the elastic diaphragm is a corrugated diaphragm.",
    "10. The panorama stitching camera of claim 1, further comprising a heater disposed at the end of the main shaft at which the lenses are disposed, wherein the heater is configured to heat the plurality of lenses simultaneously.",
    "11. The panorama stitching camera of claim 1, further comprising a fixing frame, a plurality of lens holders disposed on the fixing frame, and a ball core adjustment shaft fixed on the fixing frame, wherein, the ball core adjustment shaft is pivotally connected to the main shaft, and each of the plurality of lenses is mounted on one of the plurality of lens holders.",
    "12. The panorama stitching camera of claim 11, wherein, a pivot tube is disposed at an end of the main shaft facing away from the fixing plate; an inner wall of the pivot tube is provided with internal teeth; the ball core adjustment shaft is rotatably disposed in the pivot tube; and an outer peripheral face of the ball core adjustment shaft is provided with external teeth that engage with the internal teeth.",
    "13. The panorama stitching camera of claim 12, wherein, a gap greater than a height required for engaging the internal teeth with the external teeth is formed between the ball core adjustment shaft and the inner wall of the pivot tube; a part of the pivot tube on which the internal teeth are disposed is provided with a through-hole extending radially; a locking bar perpendicular to the axis of the pivot tube and protruding from the pivot tube is mounted in the through-hole; and the locking bar is detachably connected to the ball core adjustment shaft.",
    "14. The panorama stitching camera of claim 13, wherein, the locking bar comprises a threaded segment and a protruding segment, wherein the threaded segment passes through the through-hole and is screwed to the ball core adjustment shaft, and the minimum external diameter of the protruding segment is larger than the size of the through-hole in an axial direction of the pivot tube.",
    "15. The panorama stitching camera of claim 11, wherein, the fixing plate, the main shaft, the fixing frame, and the lens holders are all metallic members.",
    "16. The panorama stitching camera of claim 1, wherein, the elastic diaphragm is a corrugated diaphragm.",
    "17. The panorama stitching camera of claim 1, further comprising a heater disposed at the end of the main shaft at which the lenses are disposed, wherein the heater is configured to heat the plurality of lenses simultaneously.",
    "18. The panorama stitching camera of claim 1, further comprising a fixing frame, a plurality of lens holders disposed on the fixing frame, and a ball core adjustment shaft fixed on the fixing frame, wherein, the ball core adjustment shaft is pivotally connected to the main shaft, and each of the plurality of lenses is mounted on one of the plurality of lens holders."
