A head mount includes a seat body on which a mounting cavity is provided; a conversion structure, and having two connection ends of different specifications; the conversion structure is reversibly disposed in the installation cavity, and the selected connection end protrudes out of the installation cavity by flipping the conversion structure, and is adapted to The photographing device is connected, and the seat body has a limiting structure for preventing the switching mechanism from being turned over after the photographing device is connected to the connecting end. By setting the conversion structure, when it is necessary to connect with the shooting device of different interfaces, the required connection end may be flipped outside the installation cavity to connect with the corresponding shooting device as required. The invention may realize the conversion of different connection ends by simply flipping the conversion structure, thereby realizing the connection with the different interface photographing devices, the operation is simple and quick, and the connection end is not required to be disassembled, and the connection end is not easily lost.
