When an external force is applied again to rotate the first rotating part 1 relative to the second rotating part 2, the limiting protrusion 300 exits the limiting groove 311, the elastic member 302 is compressed, and the limiting protrusion 300 is compressed. The positioning protrusion 300 is limited in the positioning cavity 301 , and the first rotating part 1 can freely rotate relative to the second rotating part 2 .
[0030] In the embodiment shown in the figure, the limiting protrusion 300 is a spherical ball, and the positioning cavity 301 is a cylindrical blind hole, the diameter of which is slightly larger than the diameter of the ball.

The direction of the limit groove is precessed. The operating portion 402 is rotated by an external force and the threaded portion 401 moves toward the limiting groove 411. When the limiting protrusion 400 enters the positioning groove 411 driven by the threaded portion 401, it can move toward the limiting groove 411. The relative rotation between the first rotating part 1 and the second rotating part 2 is locked. When the operating portion 402 is reversely rotated, the threaded portion 401 moves away from the limiting groove 411 , thereby driving the limiting protrusion 400 to withdraw from the limiting groove 411 to unlock the first In the relative rotation between the rotating part 1 and the second rotating part 2, the first rotating part 1 and the second rotating part 2 can rotate with each other at this time.
[0036] It can be understood that, in other embodiments, the operating part 402 can also be replaced with other structures, for example, the rotation of the threaded part 401 relative to the second rotating part 2 is automatically controlled by means of screw driving.
[0037] The limiting protrusions 400 may be conical or cylindrical, and the shape of the limiting grooves 411 is adapted to the shape of the limiting protrusions 400 . It can be understood that, in other embodiments, the limiting protrusion 400 can also be any other suitable regular or irregular shape, and the shape of the limiting groove 411 is the same as the shape of the limiting protrusion 400 .

The following description will be given by taking a three-axis handheld pan/tilt as an example, wherein the three-axis handheld pan/tilt includes a rotation limiting structure 3 .
[0039] see Figure 3 to Figure 5 As shown, it is a schematic structural diagram of a handheld gimbal 100 provided by the present invention. The handheld gimbal 100 is a three-axis gimbal, including a first rotating shaft mechanism 5 , a second rotating shaft mechanism 6 and a third rotating shaft mechanism 7 . The third rotating shaft mechanism 7 is connected with a clamping mechanism 9, and the clamping mechanism 9 is used for clamping the photographing device. The first rotating shaft mechanism 5 , the second rotating shaft mechanism 6 and the third rotating shaft mechanism 7 can all be provided with the rotating shaft limiting structure 3 or 4 .

At this time, the rotor 60 cannot freely rotate relative to the stator 62 .
[0040] The hand-held pan/tilt also includes a controller (not shown), and a position sensor (not shown) disposed on the limit protrusion or the limit groove, the position sensor is connected with the position sensor. The controller is connected, and when the limiting protrusion is locked in the limiting groove, the controller controls the handheld pan/tilt to enter a standby state according to the position signal of the position sensor; when When the limiting protrusion is withdrawn from the limiting groove, the controller controls the handheld pan/tilt to enter a working state according to the position signal of the position sensor.
[0041] For the gimbal without the rotation restriction structure, the user needs to carry a storage bag (box) suitable for the gimbal in general use situations. When the user does not need to use the gimbal, place the gimbal in the storage bag (box). In order to ensure that the gimbal will not shake randomly during the user's carrying process; when the gimbal is used again, it is necessary to take the gimbal out of the storage bag (box) and restart the gimbal before it can be used. For the gimbal equipped with the rotation restricting structure of the present invention, after the rotation restricting structure in the gimbal cooperates, the rotor and stator of the rotating shaft mechanism of the handheld gimbal can no longer rotate freely, and the user does not need to worry about the gimbal when carrying the gimbal. Trouble with free rotation of components. At the same time, if the user forces the rotation limiting structure to reach the locked position during the normal operation of the gimbal, the gimbal will not malfunction and other abnormalities, and the gimbal will enter a standby state, which consumes very little energy. When the user uses the gimbal again, there is no need to restart the gimbal through the power control button of the gimbal again, just unlock the gimbal from the locked state of the rotation restriction structure, and the gimbal can resume normal operation. This makes it convenient for users to quickly use the gimbal anytime, anywhere.
[0042] In addition, for those of ordinary skill in the art, various other corresponding changes and deformations can be made according to the technical concept of the present invention, and all these changes and deformations should belong to the protection scope of the claims of the present invention.
