[0029] See also Figures 1 to 12The embodiment of the utility model provides a one-button storage soft light cover chuck, including: a base 1, an upper shell 2, a fixed frame 3, a turntable 4, a banner shaft 5, a slider 6, a knob 7, a chuck 8 and a threaded spring fixing pin 9.

[0030] Specifically, the base 1 is a pedestal, and a plurality of rotating shaft U-shaped grooves 101 distributed in a circumference are arranged in the base 1. A sliding groove 102 extending in the direction of the rotating shaft U-shaped groove 101 is arranged inside the rotating shaft U-shaped groove 101. The banner rotating shaft 5 is rotatably connected in the rotating shaft U-shaped groove 101, and the banner rotating shaft 5 can freely rotate in the range of 0°-60° in the rotating shaft U-shaped groove 101. A positioning hole 501 is arranged on the outer wall of the banner rotating shaft 5 and is connected to a support rod 502. In this embodiment, 16 banner rotating shafts 5 and 16 sliders 6 are installed. The banner rotating shaft 5 corresponds to the slider 6 and the threaded spring locking pin 9 one by one.

[0031] The slider 6 is slidably disposed in the slide groove 102, and the slider 6 can slide freely within the travel range of 0mm-7.5mm in the slide groove 102. The threaded spring locking pin 9 is connected to the outer side of the slider 6 through an M5 thread, and the end of the threaded spring locking pin 9 is provided with a compressible bullet head structure 901 matching the positioning hole 501.

[0032] Specifically, the fixed frame 3 is annular, and a hollow groove 301 is provided on the fixed frame 3 at a position corresponding to the slider 6, and the extension line of the hollow groove 301 passes through the center of the fixed frame 3. A limit reinforcing rib 302 is provided at the bottom of the fixed frame 3 at a position corresponding to the slide groove 102; the fixed frame 3 is fixed to the base 1 by eight M4 first cross countersunk screws 11. The top rod 601 at the top of the slider 6 is inserted into the hollow groove 301, and the limit reinforcing rib 302 limits the slider 6 in the slide groove 102.

[0033] The turntable 4 is arranged above the fixed frame 3, and the top rod on the turntable 4 corresponding to the top of the slider 6 is provided with a slot 401 and a threaded hole 402 in a strip shape and arranged obliquely; the upper shell 2 is arranged above the turntable 4 and connected and fixed to the base 1, and the upper shell 2 is fixed to the base 1 by four M4 second cross countersunk screws 12. The knob 7 passes through the upper shell 2 and is connected and fastened with the threaded hole 402 on the turntable 4; the chuck 8 is fixed to the upper shell 2 by three cross slotted screws 10.

[0034] The working principle of the one-button storage diffuser chuck of the utility model is as follows:

[0035] When the slider 6 is located at the first position S1, the diffuser chuck is in a retracted state, i.e., in an unused state. Fig.10As shown; when the knob 7 is turned to the LOCK position, the knob 7 will drive the turntable 4 to rotate counterclockwise around the axis, and the slot 401 will push the slider 6 to move linearly along the slot 102, and the turntable 4 will push the slider 6 to slide from the first position S1 to the second position S2. When the slider 6 is pushed to the second position S2, the threaded spring locking pin 9 will also move together, and its top bullet head structure 901 will be compressed and pressed against the side wall of the banner shaft 5. At this time, the banner shaft 5 will rotate 60° clockwise around the shaft U-shaped slot 101, and the positioning hole 501 on the banner shaft 5 will be rotated to the horizontal direction, and the compressed bullet head structure 901 will be pushed into the positioning hole 501 under the elastic force of the internal spring. At this time, the flexible banner shaft 5 has been locked and can no longer rotate, thereby realizing the open state of the soft light cover chuck; as shown Fig.11 shown.

[0036] When the knob 7 is turned from the LOCK position to the LOOS position, the knob 7 will drive the turntable 4 to rotate clockwise around the axis, and the slot 401 of the turntable 4 will push the slider 6 to move along the slide slot 102 in a straight line. The turntable 4 pushes the slider 6 to slide from the second position S2 to the first position S1. When the slider 6 is pushed to the first position S1, the compressed bullet head structure 901 on the threaded spring positioning pin 9 will exit the positioning hole 501 along with the slider 6, thereby releasing the locking state. The support rod 502 loses its supporting force and will automatically fall down and return to the retracted state under the action of gravity. Fig.10 shown.

[0037] As an optional implementation, Fig.12 As shown, an auxiliary pressing ring 13 can be designed. When the knob 7 is rotated to the LOCK position, the auxiliary pressing ring 13 can be used to press down in the opening direction of the support rod 502, thereby realizing the functional feature of opening and locking the soft light cloth with one button.

[0038] From the above embodiments, it can be seen that the one-button storage type diffuser chuck provided by the embodiment of the utility model realizes the one-button storage function by using a turntable to drive a slider, and the slider locks the banner shaft. When the diffuser needs to be replaced due to the shooting scene, there is no need to disassemble the entire chuck. You only need to turn the knob to the loose position to fold the support rod and quickly replace the diffuser, which greatly shortens the operation time, saves labor costs, and brings a better user experience.
