This embodiment realizes that mounting bracket 7 is connected with the rotation of second camera casing 5 through setting up connecting pin 8, only needs during the use to fix the cartridge portion 81 of connecting pin 8 on second camera casing 5 lateral wall through the elastic deformation joint and make its pivot portion 82 rotate with mounting bracket 7 and be connected and can realize that mounting bracket 7 is connected with the rotation of second camera casing 5. Compared with the prior art, the structure of this embodiment is simpler, and the assembly is convenient and fast more.

It can be understood that, in order to fix the connecting pin 8 on the side wall of the second camera housing 5 by elastically deforming and clamping, at least one of the second camera housing 5 and the connecting pin 8 is made of common elastic materials such as rubber. The connecting pin 8 of the present embodiment is made of common elastic materials such as rubber or plastic, and the material of the second camera housing 5 is not limited, and may be made of an elastic material or a non-elastic material. Of course, in other embodiments, the connecting pin 8 may not be made of an elastic material, but the second camera housing 5 is made of an elastic material, or both the connecting pin 8 and the second camera housing 5 are made of an elastic material.

Specifically, the second camera housing 5 is provided with an insertion hole 51, the insertion portion 81 is fixedly inserted into the insertion hole 51, the insertion portion 81 is provided with a clamping portion 811 and at least one rotation stopping plane 812, the inner side wall of the insertion hole 51 is provided with a clamping matching portion 511 matched with the clamping portion 811 and a rotation stopping matching plane 512 matched with the rotation stopping plane 812, the clamping portion 811 is matched with the clamping matching portion 511 to clamp the insertion portion 81 in the insertion hole 51, and the rotation stopping plane 812 is matched with the rotation stopping matching plane 512 to limit the rotation of the connecting pin 8.

In the inserting process, the rotation stopping plane 812 and the rotation stopping matching plane 512 are aligned, then the inserting portion 81 of the connecting pin 8 is inserted into the inserting hole 51, the inserting portion 81 is squeezed by the inner wall of the inserting hole 51 or the clamping matching portion 511 in the inserting process and is elastically deformed, and after the inserting portion 81 is inserted in place, the clamping portion 811 is finally clamped on the clamping matching portion 511 on the inner wall of the inserting hole 51, so that the connecting pin 8 is clamped on the side wall of the second camera shell 5 to prevent the connecting pin 8 from moving along the axial direction of the inserting hole 51.

When the connecting pin 8 is clamped to the side wall of the second camera housing 5, the rotation stop plane 812 and the rotation stop matching plane 512 are aligned with each other to be close to limit the connecting pin 8, so that the connecting pin 8 cannot rotate or can only slightly rotate to prevent the connecting pin 8 from rotating along with the mounting frame 7 when the mounting frame 7 rotates. If the connecting pin 8 rotates along with the mounting frame 7, the connecting pin can rub the inner wall of the insertion hole 51 to cause abrasion, the connecting pin 8 and the second camera shell 5 can be failed to be connected, the connecting pin 8 is rotated to be limited, the connecting pin 8 can be prevented from being abraded, and the connecting pin 8 is more durable. It is understood that the number of the rotation stop planes 812 and the rotation stop matching planes 512 is equal and can be set according to actual needs, and it can be one or more.
