The hot shoe rod assembly 12 includes a fixing rod 122 detachably mounted on the connecting portion 111. The hot shoe bar assembly 12 is detachably attached by the attachment portion 111 so that the hot shoe plate 11 can be fixed at various positions on the hot shoe bar assembly 12. The fixing rod 122 includes a top 1221 and a bottom 1222 opposite to each other, and the bottom 1222 is used for connecting the holder. The locking assembly 13 is used to secure the hot shoe bar assembly 12 to the hot shoe plate 11. The fixing member 15 is engaged with the sliding portion 112 and can connect a load to any position of the sliding portion 112.

Specifically, the load may be a camera, a mobile phone, a tablet, or a sensor, which is used to obtain external information and information. The holder can be a three-axis holder, a two-axis holder or a single-axis holder, etc. When the load is connected to the pan/tilt head, the pan/tilt head can stabilize the load and can change the orientation, angle, etc. of the load. The embodiment of the present invention is described by taking a load as a camera (including a single lens reflex camera, a video camera, a card camera, a surveillance camera, or other electronic devices with a shooting function) and a pan-tilt as a three-axis pan-tilt as an example.

In the process of mounting the fixing lever 122 at the connecting portion 111, the fixing lever 122 can be moved in a direction perpendicular to between the first end 11a and the second end 11b, that is, in the first direction, until the fixing lever 122 has a proper position with respect to the connecting portion 111, for example, the connecting portion 111 is located at a position of one-half, one-third or one-fourth of the length of the fixing lever 122, and then the hot shoe lever assembly 12 is fixed to the hot shoe plate 11 by the locking assembly 13.

During the process of connecting the load to the sliding portion 112, the fixing member 15 can slide together with the load in the direction between the first end 11a and the second end 11b, i.e., in the second direction, until the fixing member and the load have a proper position with respect to the sliding portion 112, for example, the fixing member 15 and the load are at a half position, a third position or a quarter position of the length of the sliding portion 112 in the extending direction, and then the load is fixed to the sliding portion 112 by the fixing member 15. Wherein the first direction is perpendicular to the second direction.

The fixing structure 10 of the embodiment of the invention is connected with the tripod head through the hot shoe rod assembly 12, and the fixing assembly 15 is matched with the sliding part 112 to connect the load, so that the load can be stably carried on the tripod head, and particularly when the load cannot be firmly carried on the tripod head, the auxiliary fixing of the load can be realized. In addition, since the fixing rod 122 can move in the first direction relative to the hot shoe plate 11, the load can move in the second direction relative to the hot shoe plate 11, and the cloud deck is connected to the bottom 1222 of the fixing rod 122, it is possible to move the load in the first direction relative to the cloud deck, or in the second direction, or in both the first direction and the second direction, so as to move the load to a position with a proper center of gravity, thereby realizing a stable mounting.

Referring to fig. 1 and 2 together, a fixing structure 10 according to an embodiment of the present invention includes a hot shoe plate 11, a hot shoe rod assembly 12, a locking assembly 13, a connecting assembly 14, and a fixing assembly 15.

Hot shoe 11 is generally rectangular and elongated. Hot shoe 11 includes first and second opposite ends 11a, 11b, i.e., the elongated shape has first and second ends 11a, 11b at opposite ends. The first end 11a is provided with a connecting portion 111, and the second end 11b is provided with a sliding portion 112. The connecting portion 111 may include a through hole 1111 or a blind hole, and the sliding portion 112 may include a sliding groove 1121.

Hot shoe 11 includes an upper surface 113, a lower surface 114, and sides 115. Upper surface 113 and lower surface 114 are located on opposite sides of hot shoe 11. When the connection portion 111 includes the through hole 1111, the through hole 1111 penetrates through the upper surface 113 and the lower surface 114; when the connection portion 111 includes a blind hole, the blind hole is a blind hole penetrating only the upper surface 113, or a blind hole penetrating only the lower surface 114. The central axis direction of the through-hole 1111 or the blind hole is the first direction and perpendicular to the upper surface 113 and the lower surface 114. The sliding slot 1121 penetrates the upper surface 113 and the lower surface 114. The extending direction of the sliding slot 1121 is a direction between the first end 11a and the second end 11b, that is, the extending direction of the sliding slot 1121 is a second direction. When the load is a camera, the extending direction of the sliding groove 1121 is perpendicular to the optical axis of the camera.

Upper surface 113 is formed with cold shoe grooves 116. The cold boot groove 116 is used for connecting other devices, such as a microphone, a fill light, and other devices with a cold boot male head.

When the number of cold shoe grooves 116 is one, one cold shoe groove 116 is located in the central area between the first end 11a and the second end 11 b; when the number of cold shoe grooves 116 is plural (e.g., two, three, or four), the plural cold shoe grooves 116 are equally spaced between the first end 11a and the second end 11 b. Because one cold shoe channel 116 is located in a central region between first end 11a and second end 11b, or multiple cold shoe channels 116 are equally spaced between first end 11a and second end 11b, it is advantageous to ensure that hot shoe plate 11 is evenly stressed when other devices are coupled to cold shoe channel 116. Cold shoe channel 116 includes upper portion 1161 and lower portion 1162 in communication, with the opening of upper portion 1161 being smaller than the opening of lower portion 1162. Cold shoe groove 116 may be a stepped groove formed by upper surface 113 being recessed in the direction of lower surface 114. In other embodiments, cold shoe channel 116 can also be a stepped recess formed by upper surface 113 protruding 1542 away from lower surface 114.

The upper surface 113 is provided with at least one connection port 117, for example, the upper surface 113 is provided with one, two, three or four connection ports 117. Connecting opening 117 of upper surface 113 is located between connecting portion 111 and cold shoe channel 116, and/or between cold shoe channel 116 and sliding portion 112. Bottom wall 15311 of cold shoe channel 116 may also be provided with at least one connection port 1163, for example, bottom wall 15311 of cold shoe channel 116 may be provided with one, two, three, or four connection ports 1163. Connection port 117 of upper surface 113 and connection port 1163 of bottom wall 15311 of cold shoe channel 116 are used to mechanically connect other devices. Since the upper surface 113 is provided with the cold shoe groove 116, the connection port 117, and the connection port 1163 is provided on the bottom wall 15311 of the cold shoe groove 116, the fixing structure 10 can provide a rich expansion interface to connect other devices required during the working process of the load, reduce the load of the interface of the load itself, and have a simple appearance structure. Hot shoe 11 may also include at least one retaining member 118, such as a retaining screw. The stop member 118 is threadably secured to the upper surface 113 and provides a stop for other equipment as needed.
