The locking component is disposed on a rotational connection position of the clamping arm13and the connecting arm2. Locking an angle between the clamping arm13and the connecting arm2is achieved through the locking component3disposed between the clamping arm13and the connecting arm2. The locking component3limits relative rotation of the clamping arm13and the connecting aim2, thereby avoiding the mobile phone from still rotating after adjusted the shooting angle, which greatly improves user experience of the handheld gimbal.

As shown inFIG. 3, to be specific, the locking component includes a locking ring31and a ring seat32. The ring seat32is disposed on the clamping arm13. And the ring seat protrudes toward the connecting arm2. An external thread is disposed on the ring seat32. An internal thread is disposed on a locking ring31. And the internal thread matches with the external thread. The locking component is movably disposed on the ring seat32through matching of the internal thread and the external thread. To facilitate the rotation of the locking ring31, a knurl is disposed on a periphery surface of the locking ring31to increase friction. When the clamping arm13is required to rotate, the locking ring31is moved away from the connecting arm2by loosening the locking ring31. When the clamping arm13is required to fix, the locking ring31is pressed against the connecting arm2to prevent the rotation of the clamping arm13by tightening the locking ring31. Similarly, the ring seat32is disposed on the connecting arm2and the seat ring32protrudes toward the clamping arm13. The locking ring31is moved toward the clamping arm13by matching of the internal thread and the external thread when the locking ring rotating. And the locking ring is pressed against the clamping arm13to lock the clamping arm13and the connecting arm2.

As shown inFIGS. 2 and 4, in order to improve the user experience of the clamping mechanism, the clamping arm13can rotate manually or electrically. The clamping mechanism further includes a gimbal motor. The gimbal motor includes a ring magnet41, a winding coil42, and a rotating shaft43. A first end of the rotating shaft43is fixedly connected with the connecting arm2. The ring magnet41is fixedly disposed on the connecting arm2and is coaxial with the rotating shaft43.

The winding coil42is electrically connected to the PCB18and the battery is powered by a battery.

The manner of working of the clamping mechanism of the embodiment is: before the clamping mechanism works, the locking ring31is released. The locking ring31moved downward (the direction shown in the figure). Thereby, a gap is reserved between the locking ring31and the connecting arm2. After that, opening the power of the clamping mechanism, the gimbal motor drives the clamping arm13to rotate in a certain angle, and ensures the balance of the clamping arm13and the mobile phone is disposed on the clamping arm13. When the gimbal motor is powered off, after manually rotates the clamping arm13to the desired shooting angle, the locking ring31is moved upwardly and reached the connecting arm2by tightening the locking ring31. Thereby, locking the angle between the clamping arm13and the connecting arms2is realized.

Further, as shown inFIG. 7, the present disclosure provides a handheld gimbal, which includes a handle5, a telescopic rod (not shown in figure) and the above clamping mechanism.
