Abstract

A telescopic limiting structure includes a first retractable member, including a first inclined face and a second retractable member including a second inclined face bearing against the first inclined face. The first retractable member is configured to move along a first direction. The first inclined face and the second inclined face are configured to drive the second retractable member to move along a second direction in response to the first retractable member moving along the first direction. The second direction is different from the first direction.

the second supporting part comprises two limiting parts inwardly provided at two sides of the second supporting part, respectively, the two limiting parts sharing a common intermediate supporting part and each comprising an upper boss and a lower boss arranged oppositely, and the lower boss of each of the two limiting parts comprising a portion of the second inclined face,

the press key comprises a press key block and two snapping parts extending from the press key block and each comprising a portion of the first inclined face, and

the first elastic element is arranged between the press key block and the intermediate supporting part along the first direction.

7. The telescopic limiting structure of claim 6, further comprising:

a press key bracket comprising a body and two claws extending from the body, wherein;

each of the snapping parts comprises a protruding block facing away from the other of the snapping parts, the protruding block of each of the snapping parts comprising a snapping face facing towards the press key block, and

the claws snap with the snapping faces.

8. A camera body comprising:

a fixing frame comprising;

a lens assembling opening provided on an end wall of the fixing frame and for assembling a lens;

a first assembling hole provided on an outer side wall of the fixing frame; and

a second assembling hole provided on the end wall; and

a telescopic limiting structure comprising;

a first retractable member extending into the fixing frame through the first assembling hole, the first retractable member including a first inclined face and being configured to move along a first direction; and

a second retractable member extending into the fixing frame through the second assembling hole, the second retractable member including a second inclined face bearing against the first inclined face, the first inclined face and the second inclined face being configured to drive the second retractable member to move along a second direction in response to the first retractable member moving along the first direction, and the second direction being different from the first direction.

9. The camera body of claim 8, wherein the first direction is substantially perpendicular to the second direction.

10. The camera body of claim 8, wherein:

the first retractable member comprises a press key and a first elastic element,

the second retractable member comprises a limiting boss and a second elastic element,

the first elastic element is arranged between the press key and the limiting boss along the first direction, and

the second elastic element is arranged along the second direction and is connected to the limiting boss.

11. The camera body of claim 10, wherein the limiting boss comprises:

a bracket; and

a post and a shaft protruding from the bracket, the second elastic element being sheathed on the shaft.

12. The camera body of claim 11, wherein:

the bracket comprises a first supporting part and a second supporting part,

the post and the shall extend approximately perpendicularly from two opposite surfaces of the first supporting part, respectively, and are approximately parallel to the second supporting part, and

the first elastic element is arranged between the press key and the second supporting part along the first direction.

13. The camera body of claim 12, wherein:
