wherein the casing and the hood assembly are configured to compress the sealing member after the casing and the hood assembly are locked to each other. ### Claim 3 (depends on 1) The protective casing structure of claim 1, wherein the hood assembly further includes: a see-through member including a see-through unit facing the electronic device loaded in the sealed cavity; and a support configured to be fastened to the casing and including an inner cavity penetrating the support, a first end of the inner cavity being fixed to the see-through member, and a second end of the inner cavity forming the hood. ### Claim 4 (depends on 3) The protective casing structure of claim 3, wherein the support is configured as a cylindrical structure. ### Claim 5 (depends on 3) The protective casing structure of claim 3, wherein the second end of the support is provided with a groove surrounding the hood configured to, when the hood abuts against the opening, receive a portion of the casing with a groove wall of the groove attaching the portion of the casing. ### Claim 6 (depends on 5) The protective casing structure of claim 5, wherein one end of the casing towards the support is provided with a step structure surrounding the opening, a convex of the step structure configured to be inserted into the groove, and a concave of the step structure forms an avoidance groove for a groove edge of the groove. ### Claim 7 (depends on 5) The protective casing structure of claim 5, wherein an accommodation cavity is formed between the portion of the casing inserted in the groove and a bottom of the groove, and a sealing member is provided in the accommodation cavity. ### Claim 8 (depends on 1) The protective casing structure of claim 1, further comprising: a fastener configured to lock the casing to the hood assembly. ### Claim 9 (depends on 8) The protective casing structure of claim 8, wherein the fastener includes a locking ring, and two ends of the locking ring are connected to the casing and the hood assembly, respectively. ### Claim 10 (depends on 9) The protective casing structure of claim 9, wherein: in an axial direction of the locking ring, one end of an inner wall of the locking ring is provided with an inner thread, and another end of the inner wall of the locking ring is provided with an inner boss; an outer wall of one of the casing and the hood assembly is provided with an outer thread, and an outer wall of another one of the casing and the hood assembly is provided with an outer boss; and after the casing and the hood assembly are locked by the locking ring, a threaded connection is formed between the inner thread and the outer thread, and the inner boss and the outer boss are clamped with each other. ### Claim 11 (depends on 10) The protective casing structure of claim 10, wherein: a first connecter is provided adjacent to the outer boss at the outer wall of the another one of the casing and the hood assembly provided with the outer boss, and a second connecter is provided at the inner wall of the locking ring; and the first connecter is configured to cooperate with the second connecter to realize a connection of the locking ring with the casing or the hood assembly, and to provide guidance for a movement of the locking ring. ### Claim 12 (depends on 11) The protective casing structure of claim 11, wherein the second connecter is arranged at the inner boss. ### Claim 13 (depends on 1) The protective casing structure of claim 1, wherein one of the support and the casing is provided with a fastening member, and another one of the support and the casing is provided with a fastening fitting member configured to be connected with the fastening member. ### Claim 14 (depends on 1) The protective casing structure of claim 1, wherein the casing is further provided with a key mounting member, and a key assembly is mounted at the key mounting member. ### Claim 15 (depends on 14) The protective casing structure of claim 14, wherein: the key assembly includes a package, a pressing member, a resetting member, and a sealing assembly; the key mounting member includes a through hole passing through the casing; the pressing member is arranged passing through the resetting member, the sealing assembly, and the through hole in sequence; one end of the resetting member is configured to abut against the pressing member, and another end of the resetting member is configured to abut against the sealing assembly or the casing; and the package covers the pressing member, the reset member, and the sealing assembly, and is connected to the casing in a sealed manner. ### Claim 16 A handheld gimbal comprising: a protective casing structure including: a hood assembly including a hood; a casing configured to be locked to the hood assembly to form a sealed cavity, one end of the casing being provided with an opening adapted to a shape of and abutting against the hood; and a mounting member arranged in the sealed cavity; and a gimbal fixed at the mounting member and configured to mount an electronic device; wherein the sealed cavity provides a space for the electronic device to move in the space. ### Claim 17 (depends on 16) The handheld gimbal of claim 16, wherein: the gimbal is fixed at the mounting member through a loading assembly; the loading assembly includes a movable loading member and at least one fixed loading member connecting the movable loading member to the mounting member; and the movable loading member is provided with an open groove configured to clamp a gimbal arm of the gimbal. ### Claim 18 (depends on 17) The handheld gimbal of claim 17, wherein: the at least one fixed loading member is at least one first fixed loading member; and the loading assembly further includes at least one second fixed loading member configured to lock the gimbal arm. ### Claim 19 An imaging device comprising: a handheld gimbal including: a protective casing structure including: a hood assembly including a hood;
