[0023] Example 1:

[0024] like Figure 1 As shown, in this embodiment, the present invention includes a knob 1, a first connecting member 2, and a second connecting member 3. The knob 1 is disposed on the first connecting member 2, and the knob 1 has a first chamber 5 for the first connecting member 2 to move up and down. The second connecting member 3 has a second chamber 6. The lower end of the first connecting member 2 is rotatably connected to the second chamber 6, and the upper end of the second connecting member 3 abuts against the lower end of the knob 1. When the knob 1 is rotated, the upper end of the first connecting member 2 rotates to connect with an external device. When the first connecting member 2 is connected with the external device, the lower end of the first connecting member 2 presses upward against the second connecting member 3 to lock the direction of the gimbal. The upper end of the first connecting member 2 can be connected to an external device, and the lower end of the second connecting member 3 can be connected to a bottom bracket.

[0025] It should be noted that by rotating the knob 1, the first connector 2 is driven to rotate simultaneously. At this time, the second connector 3 does not rotate, so that the first connector 2 can be connected to the external device. Meanwhile, during the process of connecting with the external device, the first connector 2 will move upward relative to the knob 1, so that the lower end of the first connector 2 presses the second connector 3 upward, and the upper end of the second connector 3 presses the lower end of the knob 1, thereby locking the direction of the gimbal.

[0026] In contrast to the shortcomings of existing technologies, in this invention, by rotating the knob 1, the first connecting piece 2 is simultaneously rotated to connect with an external device. Furthermore, the lower end of the first connecting piece 2 can be pressed upwards during the connection process to lock the direction of the gimbal. Therefore, this invention can lock the gimbal to the external device by rotating the knob 1, while simultaneously locking the direction of the gimbal, thus achieving one-click locking and simplifying the installation process. This makes this invention easy to operate.

[0027] In the embodiment, the first connecting piece 2 comprises a first screw head 7 and a second screw head 8, the lower end of the first screw head 7 is fixedly connected to the upper end of the second screw head 8, the lower end of the second screw head 8 is provided with a circular arc head 9, the circular arc head 9 is rotatably connected in the second connecting piece 3; the second connecting piece 3 comprises a circular arc cover body 10, the second cavity 6 is located in the circular arc cover body 10, the top of the second cavity 6 is provided with a first arc surface 11, the circular arc head 9 is rotatably connected in the second cavity 6 and abuts on the first arc surface 11, the lower end of the knob 1 is provided with an opening 12, the opening 12 is provided with a second arc surface 13, the outer side of the circular arc cover body 10 is provided with a third arc surface 15, the third arc surface 15 abuts on the second arc surface 13, the second arc surface 13 and the circular arc head 9 can be pressed on the third arc surface 15 and the first arc surface 11 respectively when the knob 1 rotates;

[0028] As can be seen from the above scheme, the knob 1 is rotated to drive the first screw head 7 and the second screw head 8 to rotate simultaneously, so that the upper end of the first screw head 7 can be connected with an external device; wherein the first screw head 7 moves upward relative to the knob 1 in the process of being connected with the external device, so that the circular arc head 9 located at the lower end of the second screw head 8 can move upward and abut on the first arc surface 11, and the second arc surface 13 located at the lower end of the knob 1 is pressed to the third arc surface 15 located on the outer side of the circular arc cover body 10, forming a cooperative force of the circular arc head 9 and the second arc surface 13 on the first arc surface 11 and the third arc surface 15 located on the inner and outer sides of the circular arc cover body 10 to realize clamping, so as to lock the direction of the gimbal while locking the external device, and the double spherical clamping form can improve the structural stability of the gimbal, can support a heavier external device, and improve the stability after the gimbal is installed, therefore, the gimbal of the utility model can simplify the installation process, and the double spherical clamping mode can improve the stability of the external device after installation.

[0029] In the embodiment, the first cavity 5 is a polygonal cavity, the first connecting piece 2 has a polygonal body 21, the polygonal body 21 is located in the first cavity 5, and the polygonal body 21 has a movable gap between the upper end of the first cavity 5 when the first connecting piece 2 is locked. Wherein, through the setting of the polygonal cavity and the polygonal body 21, the knob 1 can drive the first screw head 7 and the second screw head 8 to rotate simultaneously when rotating. Specifically, when the gimbal is connected between the external device and the bottom support, the gimbal is equivalent to a gasket, at this time the force of the external device acts on the circular arc head 9;

[0030] From the above, through the setting of the first chamber 5, when the first connecting piece 2 moves up and down, the polygonal body 21 of the first connecting piece 2 can be limited by the first chamber 5, and the polygonal body 21 has a moving gap between the upper end of the first chamber 5 when the first connecting piece 2 is locked, and the first screw head 7 does not reach the upper end of the first chamber 5, so that the polygonal body 21 has a moving gap when the first connecting piece 2 is locked and does not generate a force on the knob 1, and when the direction of the holder is adjusted, the force of the external device can be avoided to affect the rotation of the arc head 9, thereby facilitating the rotation of the arc head 9, so as to easily adjust the direction of the holder.

[0031] Embodiment two:

[0032] The difference between the embodiment two and the embodiment one is that the specific structures of the first connecting piece and the second connecting piece are different, and the specific structures are as follows:

[0033] As shown in Figure 2 , in the embodiment, the first connecting piece 2 includes a first screw head 7 and a second screw head 8, the lower end of the first screw head 7 is fixedly connected to the upper end of the second screw head 8, and the lower end of the second screw head 8 is rotatably connected in the second connecting piece 3; the second connecting piece 3 includes a connecting seat 16, the upper end surface of the connecting seat 16 abuts against the lower end surface of the knob 1, the upper end surface of the connecting seat 16 and the lower end surface of the knob 1 are in surface contact, the second chamber 6 is located in the connecting seat 16, the lower end of the second screw head 8 is rotatably connected in the second chamber 6, the lower end of the second screw head 8 abuts against the upper end of the second chamber 6, and the lower end of the second screw head 8 and the upper end of the second chamber 6 are in surface contact, and the lower end surface of the knob 1 and the lower end of the second screw head 8 can be pressed against the upper end surface of the connecting seat 16 and the upper end of the second chamber 6, respectively, when the knob 1 rotates.

[0034] From the above, the upper end of the first screw head 7 can be connected with the external device, and the lower end of the connecting seat 16 can be connected with the bottom support, specifically, when the knob 1 rotates, the first screw head 7 and the second screw head 8 rotate at the same time, and the connecting seat 16 does not rotate, so that the first screw head 7 can be connected with the external device; at the same time, when the first screw head 7 is connected with the external device, the first screw head 7 and the second screw head 8 can move upward relative to the knob 1 at the same time, so that the lower end surface of the knob 1 and the lower end of the second screw head 8 are pressed against the upper end surface of the connecting seat 16 and the upper end of the second chamber 6, respectively, to lock the direction of the holder, and therefore, the utility model can lock the direction of the holder at the same time when the holder is locked with the external device by rotating the knob 1, so as to realize one-key locking and simplify the installation process.

[0035] Embodiment three:

[0036] The difference between this embodiment three and embodiment two lies in the specific structure of the second connector, as detailed below:

[0037] like Figure 3 As shown, in this embodiment, the second connector 3 includes a connecting bracket 17 and a cylinder 18. The second chamber 6 is located in the connecting bracket 17, and the cylinder 18 is located in the second chamber 6. The top of the second chamber 6 is provided with a first arc surface 11, and the outer side of the cylinder 18 abuts against the first arc surface 11. A third chamber 19 is provided in the cylinder 18, and the lower end of the second screw head 8 is rotatably connected to the third chamber 19. The upper ends of the knob 1 and cylinder 11 are in surface contact. The lower end of the knob 1 has a fixing block 20, which is fixedly connected to the connecting bracket 17. The lower end of the fixing block 20 has an opening 12, on which a second arc surface 13 is provided. The outer side of the connecting bracket 17 has a third arc surface 15, which abuts against the second arc surface 13. The second arc surface 13 and the cylinder 18 can press against the third arc surface 15 and the first arc surface 11 respectively when the knob 1 is rotated. The direction of the gimbal is adjusted by rotating the cylinder 18 in the second chamber 6.

[0038] As can be seen from the above, specifically, when knob 1 is rotated, the first screw head 7 and the second screw head 8 rotate simultaneously, while the fixing block 20, the cylinder 18, and the connecting bracket 17 do not rotate, allowing the first screw head 7 to connect to the external device. At the same time, when the first screw head 7 is connected to the external device, it can move upward relative to knob 1 at the same time as the second screw head 8, so that the second arc surface 13 and the cylinder 18 are respectively pressed against the third arc surface 15 and the first arc surface 11 to lock the direction of the gimbal. Therefore, this utility model can lock the direction of the gimbal at the same time by simply rotating knob 1 to lock the gimbal to the external device, thereby achieving one-click locking and simplifying the installation process.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
