[0037] Please refer to Figure 3 And Figure 5The locking piece B42 is movably sleeved on the support 15, and is located on the inner side of the stop plate 61, so that the locking piece B42 can make circumferential movement around the support 15. The side of the holder 1 is throughly provided with a strip-shaped hole 9 which is connected between the inside and the outside. The locking piece B42 is fixedly connected with a push rod 10. The operating end of the push rod 10 extends outward through the strip-shaped hole 9. The push rod 10 can be used to push the locking piece B42 to rotate and make circumferential movement horizontally.

[0038] Please refer to Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , the support 15 is outwardly protruded from the center of the cover plate 6 towards the locking piece B42, and a screw hole is formed through the center of the support 15. A clamping seat 22 for mounting a photographic equipment can be mounted above the cover plate 6 through screwing with the screw hole.

[0039] The locking piece B42 is movably sleeved on the support 15, and is located on the inner side of the stop plate 61, so that the locking piece B42 can make circumferential movement around the support 15.

[0047] The usage process of this utility model: The initial state of the locking component 4 is as follows Figure 6 As shown (the universal ball 3 is not locked, and the clamp 22 can be freely moved for angle adjustment), at this time, the distance between the locking member A41 and the locking member B42 is at its minimum. Move the lever 10 along the locking direction indicated on the sign 12. The lever 10 drives the locking member B42 to rotate. The rotation of the locking member B42 causes the two protrusions 5 between the locking members A41 to move along the slope direction on the inclined plane. The distance between the two locking members increases accordingly. The locking member A41 moves under the push of the locking member B42 and generates a force on the vertical plane to abut against the universal ball 3, thereby locking the universal ball 3 and fixing the angle of the clamp 22. When it is necessary to unlock the universal ball 3 and adjust the angle of the clamp 22, simply move the lever 10 in the opposite direction.
