The second protrusion 220 is provided with a card slot, and the card slot is located on the inner side. The card block of the photographic equipment can be inserted into the card slot. The second protrusion 220 is a step-shaped structure, and the card slot is located on one side of the hypotenuse of the second protrusion 220. The hypotenuse sides of the two second protrusions 220 are arranged opposite to each other.

[0035] It should be noted that, in other embodiments, the positioning portion 210 can be designed as two symmetrical rectangular blocks, the two rectangular blocks are arranged at a certain angle, the sides of the two rectangular blocks that are close to each other are the inner sides, and the sides that are far away from each other are the outer sides, the through hole 230 is arranged on the inner side, and the card block of the photographic equipment is arranged between the two rectangular blocks.

[0036] Reference Figure 1 and Figure 2The limiting mechanism 100 is provided with a push rod 110, a locking member 120 and an elastic member 130.
