Preferably, the third connector 34 is also a bolt. Further, a cushion layer 35 is arranged between the second connector 32 and the lower assembly 1.

Further, the upper assembly 2 further includes a locking buckle 23 mounted on the upper assembly body 21, a second fixing member 27 mounted on the lower side of the upper assembly body 21, and a second locking member 26 disposed between the upper assembly body 21 and the second fixing member 27 for locking the locking buckle 23.

Returning to fig. 4, 7A and 7B, the locking buckle 23 is used to lock the quick-release plate 4 to the upper assembly 2. The locking buckle 23 includes a locking buckle body 231 movable with respect to the upper assembly body 21, a connection pin 233 to mount the locking buckle body 23 to the upper assembly body 21, an elastic member 232 mounted between the locking buckle body 231 and the connection pin 233, a receiving groove 235 provided at an upper end of the locking buckle body 231 for mounting the quick-mounting plate mounting portion 42 of the quick-mounting plate 4, and a protrusion 234 extending from one side of the locking buckle body 231. In this embodiment, the latch body 231 is configured as a snap fastener. The upper assembly body 21 of the upper assembly 2 is provided with a recessed mounting recess 211 at a side thereof remote from the upper assembly connecting portion 22, and the connecting pin 233 is disposed at the mounting recess 211. The elastic member 232 is sleeved on the connecting pin 233 and abuts against the inner side of the locking buckle body 231, so as to be used for automatically resetting the locking buckle body 231. In the present embodiment, the elastic member 232 is a torsion spring. More preferably, the elastic member 232 is a double torsion spring. The receiving slot 235 is parallel to the recess 28 of the upper assembly 2, both together forming a mounting slot for mounting the quick-mounting plate 4. The cross section of the protrusion 234 is trapezoidal with a wider upper part and a narrower lower part. The protrusion 234 is disposed between the upper assembly body 21 and the second fixing member 27 and is lockable and releasable by the second locking member 26, thereby locking and releasing the locking buckle body 231 to achieve the installation and removal of the quick-release plate 4. The protrusion 234 is spaced apart from the second fixing member 27 so as not to block the movement of the latch body 231 when the latch body 231 needs to be pressed.

In the present embodiment, the second fixing member 27 is mounted on the lower surface of the upper assembly body 21. The upper assembly body 21 is provided with a second receiving portion 212 recessed at a position corresponding to the second fixing member 27. A receiving space is formed between the second fixing member 27 and the second receiving portion 212 for receiving the second locking member 26. The second fixing member 27 includes a second fixing member body 271 and two second notches 272 formed by recessing on one side of the second fixing member body 271. Preferably, the second fixing body 271 has a plate shape. Alternatively, the outer circumferential profile of the second fixing body 271 may be set according to actual needs. The second notch 272 is U-shaped. Alternatively, the shape of the second notch 272 may be set according to actual needs. The latch body 231 of the latch 23 can be pushed out from the second notch 272. A receiving space for receiving the second locking member 26 is formed between the second fixing member body 271 and the second receiving portion 212. The second locking member 26 is rotatable in the receiving space with respect to the second fixing member 27 to lock and release the protrusion 234 of the locking buckle 23.

The second locking member 26 includes an eccentric portion 261, a second driving portion 262 driving the eccentric portion 261 to rotate, and a release port 263 provided at an end of the eccentric portion 261 remote from the second driving portion 262. A coupling hole is provided in the middle of the eccentric portion 261 for rotatably coupling between the second fixing member 27 and the lower side of the upper assembly body 21. In the present embodiment, the outer peripheral side of the eccentric portion 261 is provided as an inclined arc surface. Preferably, the circumference of the outer circumferential side of the eccentric portion 261 decreases from bottom to top. The eccentric portion 261 can abut against the protrusion 234 of the locking buckle 23 to lock the locking buckle 23, thereby preventing the locking buckle 23 from releasing the quick-release plate. The second driving part 262 protrudes from a receiving space formed between the second fixing body 271 and the second receiving part 212 so that a user can rotate the second locking member 26. In this embodiment, the second driving part 262 is configured as a handle. The release port 263 is used to release the lock of the protrusion 234 of the locking buckle 23. In this embodiment, the relief port 263 is generally L-shaped. Preferably, the release port 263 is perpendicular to the second fixture 27.

Referring to fig. 4, 9A and 9B together, in use, the user rotates the second driving portion 262 such that the eccentric portion 261 abuts the protrusion 234 of the locking buckle 23 to lock the locking buckle 23, thereby achieving installation of the quick-mounting plate 4; alternatively, the user rotates the second driving part 262 such that the eccentric part 261 is deviated from the protrusion 234 of the latch 23 and the release port 263 is rotated to the protrusion 234 to release the locking of the latch 23 and then presses the latch main body 231 of the latch 23, thereby allowing the quick-release plate 4 to be detached from the upper assembly 2. The arrangement makes the installation and the disassembly of the quick-acting plate simple, and the unlocking is easy, so that the quick-acting plate can be instantly loosened, and the unexpected loosening of the quick-acting plate can be prevented.

Returning to fig. 4, the upper assembly body 21 of the upper assembly 2 is also provided with a tool receiving portion 29 for receiving the wrench 5. In the present embodiment, the tool receiving portion 29 is recessed downward.

Fig. 10 shows a camera device 200 with a tilt head 100 according to the present invention, which may be, for example, a unipod with a tilt head, or other camera devices including a tilt head.

The photographic device and the turnover cradle head thereof provided by the invention have the advantages of simple and compact structure, simplicity and rapidness in installation and disassembly, convenience in locking, reliable locking effect and improvement of connection safety.
