Because the fixing piece 3 has various forms (see above), the application can realize the switching of the standard fixing piece 3 by utilizing the transition component 4, so that the fixing pieces 3 with different structural forms can be matched with the first cold shoe base 1 and the second cold shoe base 2 with the same structure to rotate, and the adaptability and the convenience of the product are greatly improved; at the same time, the fixing member 3 can also facilitate its rotation relative to the first cold shoe 1 and the second cold shoe 2 by means of the transition assembly 4. Moreover, the fixing member 3 may have two rotation modes: 1) the fixed part 3 and the transition component 4 are relatively fixed and can rotate relative to the first cold shoe base 1 and the second cold shoe base 2; 2) the fixture 3 is rotatable relative to the transition assembly 4, the first cold shoe 1 and the second cold shoe 2.

In some embodiments, the transition assembly 4 includes a cover plate 41 and a shaft seat 42, the shaft seat 42 is fixedly connected to the cover plate 41 and forms the second cavity 20 therebetween, the fixing member 3 and the shaft seat 42 are fixedly or rotatably disposed in the second cavity 20, and the cover plate 41 and the shaft seat 42 are received in the first cavity 10. For example, the fixture 3 in the rotating cold shoe shown in fig. 1 and 4 is rotatably disposed within the second cavity 20 such that the fixture 3 is rotatable relative to the transition assembly 4, the first cold shoe 1, and the second cold shoe 2; as another example, the fixing member 3 of the rotating cold shoe shown in fig. 5, 6 and 7 is fixed to the shaft seat 42, so that the fixing member 3 and the transition member 4 are fixed relative to each other and can rotate relative to the first cold shoe seat 1 and the second cold shoe seat 2. Through setting up transition subassembly 4 into components of a whole that can function independently package assembly, can conveniently be to the installation of mounting 3 or convenient and mounting 3's cooperation, when mounting 3 rotatably sets up in second cavity 20 moreover, can avoid mounting 3 and second cold shoe seat 2 to produce the contact to can further increase rotatory cold shoe's life.

In some embodiments, the second cold shoe base 2 is provided with a fixing portion 21, and the cover plate 41 and the shaft seat 42 are accommodated in the first cavity 10 by being engaged with the fixing portion 21. As can be seen from the above analysis, the transition component 4 can be fixed or rotated relative to the second cold shoe base 2, and when the transition component is the former, the fixing portion 21 can be an internal thread, and one of the cover plate 41 or the shaft seat 42 has an external thread to cooperate with the fixing portion 21, so as to be fixed inside the second cold shoe base 2; of course, the fixing portion 21 may be other structures capable of achieving the fixing with the transition component 4, such as a snap structure, an interference fit structure, and the like, and is not limited in detail herein. The fixing portion 21 may be a protrusion extending from the inner wall of the second cold shoe 2 into the first cavity 10 to support the cover plate 41 or the cover plate 41 and the shaft seat 42 when the transition component 4 rotates relative to the second cold shoe 2.

In some embodiments, the fixing portion 21 is a circular protrusion, the cover 41 is disposed on one side of the circular protrusion, and at least a portion of the axle seat 42 is disposed on the other side of the circular protrusion, so that the fixing portion 21 can be located between the cover 41 and the axle seat 42 by fixing the cover 41 to the axle seat 42. For example, when the pressure ratio generated between the cover plate 41, the axle seat 42 and the annular protrusion is large, it is also considered that the transition member 4 may be fixed with respect to the second cold shoe seat 2; conversely, if the pressure ratio created between the cover plate 41, the axle seat 42 and the annular protrusion is relatively low, then it is assumed that the transition member 4 is rotatable relative to the second cold shoe 2. So to speak, by arranging the cover plate 41 on one side of the annular protrusion and at least part of the axle seat 42 on the other side of the annular protrusion, it is achieved that the transition member 4 is rotatable relative to the second cold shoe 2.

In some implementations, the first gasket 51 may be made of a plastic material, such as nylon, PVC, PET, etc.

In some embodiments, the second bearing 422 is provided with a second spacer 52 along the direction in which the fixing member 3 protrudes out of the first cavity 10. When the rotary cold boot is mounted on the camera frame and the transition assembly 4 can rotate relative to the second cold boot base 2, the second shaft base 422 can be prevented from scratching the camera frame by arranging the second gasket 52 on the second shaft base 422 along the direction in which the fixing member 3 extends out of the first cavity 10. In some implementations, the second gasket 52 may be fixed on the second shaft seat 422 by gluing, and the second gasket 52 may be made of a silicone material.

In some embodiments, the top surface of the cover plate 41 does not extend beyond the top surface of the second cold shoe 2, so that interference between the cover plate 41 and the bottom surface of the first cold shoe 1 is avoided. The cover plate 41 is connected with the shaft seat 42 through the fastening piece 43, the cover plate 41 is provided with the tapered hole 411, the head of the fastening piece 43 is tapered, so that the thickness of the cover plate 41 can be thinner, the manufacturing cost is further reduced, and meanwhile, the fastening piece 43 with the tapered head can extrude the tapered hole 411, so that the cover plate 41 is tightly connected with the shaft seat 42. In some implementations, the fastener 43 may be a screw with a tapered head. The top surface of the fastening member 43 does not extend beyond the top surface of the cover plate 41, so that the fastening member 43 is prevented from interfering with the bottom surface of the first cold shoe 1.

In some embodiments, the cover plate 41 is further provided with a positioning hole 412, the shaft seat 42 is further provided with a positioning post 421a, and the positioning post 421a can be inserted into the positioning hole 412, so as to achieve the positioning and the positioning of the cover plate 41 and the shaft seat 42, so that the fastening member 43 can fasten the cover plate 41 and the shaft seat 42 correctly and quickly.

With reference to fig. 1 to fig. 3, the first cold shoe base 1 further has a first through hole 115, the cover plate 41 further has a second through hole 413, and the first through hole 115, the second through hole 413 and the second cavity 20 are communicated to expose the head of the fixing member 3, so as to facilitate fastening of the fixing member 3.

In some embodiments, the fixing member 3 may be directly fixed to the camera frame, or may be fixed to the camera frame through another adaptor, where the specific structure of the fixing member 3 may be adjusted according to actual conditions. In some embodiments, the fixing member 3 may include one screw 31 (see fig. 1), two screws 31 (see fig. 4), one screw 31 and two positioning pins 32 (see fig. 5), a chute locking member 33 (see fig. 6) or a cold boot locking member 34 (see fig. 7), and the specific structure of the fixing member 3 is not particularly limited in this application as long as the fixing member 3 can be fixedly connected with the camera bezel. In the case of the rotary cold boot shown in fig. 7, the fixing part 3 further includes an adjusting ring 35, and the gap between the cold boot locking member 34 and the external cold boot blade can be realized by screwing the adjusting ring 35, so as to tighten or loosen the cold boot locking member 34 and the external cold boot blade.
