For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] Referring to Figure 1 and Figure 2 , the one-key locking holder device of the embodiment of the present application comprises: a seat body 100, a spherical cavity 101 with an opening is arranged in the seat body 100; a ball head 200 movably arranged in the spherical cavity 101 to rotate relative to the spherical cavity 101; a connecting rod 300 movably arranged in the ball head 200, one end of the connecting rod 300 can protrude from the surface of the ball head 200 to make the ball head 200 abut against the opening edge of the spherical cavity 101, the other end of the connecting rod 300 has a threaded column 310 protruding from the opening of the spherical cavity 101; a knob part 400 is threadedly connected to the threaded column 310 to be able to rotate relative to the threaded column 310, a torque transmission mechanism is arranged between the knob part 400 and the threaded column 310; when the knob part 400 rotates in a first clockwise direction, the threaded column 310 is driven to rotate together by the torque transmission mechanism to connect an external device, the knob part 400 continues to rotate in the first clockwise direction to drive one end of the connecting rod 300 to protrude from the surface of the ball head 200 to tightly abut the ball head 200 against the opening edge of the spherical cavity 101; when the knob part 400 rotates in a second clockwise direction, it can drive one end of the connecting rod 300 to retract to the inside of the ball head 200 and then drive the threaded column 310 to be detached from the external device.

[0026] When the above holder device is connected with the external device, the knob 400 is first rotated in the first clockwise direction and drives the threaded column 310 to be screwed on the external device through the torque transmission mechanism. When the knob 400 continues to rotate in the first clockwise direction, the locking force between the threaded column 310 and the external device is greater than the torque that can be transmitted by the torque transmission mechanism, or the torque transmission mechanism does not intervene in the work, so the knob 400 can rotate relative to the threaded column 310, thereby driving one end of the connecting rod 300 to extend from the ball head 200 to tightly press the ball head 200 against the spherical cavity 101, so as to connect the connecting rod 300 and the external device while locking the ball head 200, thereby realizing the one-key locking function and improving the convenience of use.

[0027] Referring to Figure 1 and Figure 2 In some embodiments of the present application, in order to better connect the external device, the end of the connecting rod 300 away from the ball head 200 is fixedly provided with a bearing plate 500, and the torque transmission mechanism includes a spring member 610 arranged between the bearing plate 500 and the knob 400, and the two ends of the spring member 610 are elastically abutted against the bearing plate 500 and the knob 400, respectively. It can be understood that the first clockwise direction is the clockwise direction in which the threaded column 310 is screwed on the external device. When the knob 400 rotates in the first clockwise direction, the spring member 610 transmits the torque to the bearing plate 500 through the friction force, thereby driving the knob 400 and the bearing plate 500 to rotate in the first clockwise direction together, and then the threaded column 310 is screwed on the external device. Thereafter, the knob 400 continues to rotate in the first clockwise direction, and the torque of the spring member 610 acting on the bearing plate 500 is less than the locking force between the threaded column 310 and the external device, so the knob 400 rotates relative to the connecting rod 300 on the bearing plate 500. Since the knob 400 is threadedly connected with the threaded column 310, the connecting rod 300 can extend out of the surface of the ball head 200 under the limiting structure of the ball head 200. At this time, part of the surface of the ball head 200 will be tightly pressed against the opening edge of the spherical cavity 101, thereby locking the ball head 200 and fixing the angular position of the external device. When the knob 400 rotates in the second clockwise direction, the knob 400 rotates relative to the connecting rod 300 on the bearing plate 500, and one end of the connecting rod 300 is retracted into the interior of the ball head 200. After the connecting rod 300 moves a certain stroke, it cannot continue to move. At this time, the knob 400 continues to rotate in the second clockwise direction, and the knob 400 and the connecting rod 300 can rotate relative to the external device as a whole, thereby dismounting the threaded column 310 from the external device. It should be noted that when the torque transmission mechanism adopts a rigid structure, the torque that can be transmitted by the torque transmission mechanism is greater than the locking force between the threaded column 310 and the external device, so the knob 400 can directly dismount the holder device from the external device by rotating in the second clockwise direction.

[0028] Referring to Figure 1 and Figure 2In some embodiments of the present application, the torque transmission mechanism further comprises a clutch 620 movably arranged on the knob 400 and a combination groove 501 arranged on the bearing plate 500 and matched with the clutch 620. It can be understood that when the knob 400 rotates in the first direction, the bearing plate 500 and the threaded column 310 are driven to rotate by the spring 610, in order to ensure the fastening force between the threaded column 310 and the external device, the clutch 620 is extended into the combination groove 501, and the knob 400 and the bearing plate 500 can rotate as a whole. When the knob 400 needs to rotate relative to the threaded column 310 on the bearing plate 500 to drive the connecting rod 300 to move relative to the ball head 200, the clutch 620 and the combination groove 501 are separated. In the embodiment, a plurality of combination grooves 501 are arranged at intervals around the outer peripheral wall of the bearing plate 500, and the clutch 620 is movably arranged on the knob 400 away from the combination groove 501 by using an elastic member. When in use, the clutch 620 only needs to be pressed.

[0029] Referring to Figure 1 In some embodiments of the present application, the upper end of the knob 400 is concave downward and provided with a recess 402, the bearing plate 500 is accommodated in the recess 402 and can move up and down relative to the bottom wall of the recess 402, and the two ends of the spring 610 abut against the bottom wall of the recess 402 and the bottom wall of the bearing plate 500, respectively. The bearing plate 500 is accommodated in the recess 402, which helps to improve the structural compactness of the gimbal device, and the knob 400 protects the bearing plate 500. Since the bearing plate 500 is not exposed, only the appearance quality of the knob 400 needs to be ensured, which is conducive to reducing the cost.

[0030] Referring to Figure 1 and Figure 2 In some embodiments of the present application, the ball head 200 is provided with a sleeve 700 extending out of the opening of the spherical cavity 101, the connecting rod 300 is arranged in the sleeve 700, the knob 400 is arranged outside the sleeve 700 and can rotate relative to the ball head 200, and the inside of the knob 400 is fixedly provided with a nut 800 matched with the threaded column 310. It can be understood that the sleeve 700 is used to connect the knob 400 so that the knob 400 can rotate the connecting rod 300 on the ball head 200, and when the knob 400 rotates, the threaded column 310 on the connecting rod 300 moves along the nut 800.

The knob 400 with the above structure does not need glue or other fastening structures to install the nut 800 and the sleeve 700, which is convenient for assembly and production.

It should be noted that the moving guide 920 is the above-mentioned limiting structure, when the knob 400 rotates relative to the screw rod, the polygonal part 320 moves along the moving guide 920, thereby extending out of the surface of the ball head 200 or retracting into the inside of the ball head 200, the structure is very simple and ingenious.
