[0024] In the above scheme: by rotating the concave seat 2, the horizontal rotation of the camera is adjusted, and then the outer ring seat 4 is rotated to adjust the longitudinal rotation of the camera, and then the inner ring seat 5 is rotated to adjust the left and right rotation of the camera, so as to realize three-axis adjustment and ensure the quality of shooting.

[0025] The second embodiment is different from the first embodiment in that: See also Figure 1 and Figure 2 In the embodiment of the present invention, the positioning mechanism 6 includes two gears 61 rotatably arranged on the end surface of one side of the inner ring seat 5, and the two gears 61 are meshed with each other. One end of one of the gears 61 is located in the hollow structure inside the inner ring seat 5 and is connected to a limiting shaft 62. The end of the limiting shaft 62 away from the gear 61 rotates through the hollow structure inside the inner ring seat 5 and is connected to a knob 63.

[0029] It should be added that: the limiting shafts 62 on the two sets of positioning mechanisms 6 are fixed on one of the gears 61 and the other on the other gear 61. In this way, under the transmission of the belt 93, the two positioning rollers 67 on the two positioning mechanisms 6 will open or merge at the same time to complete the positioning and clamping work.

[0030] For further information, see Figure 1 and Figure 2 In the embodiment of the present invention, a layer of rubber pad is bonded to the outside of the positioning roller 67, and the rubber pad is soft to prevent the lens housing from being damaged by clamping.

A limiting slot 8412 which is communicated with the interior of the hollow bar 847 is provided on the upper part of one end of the hollow bar 847 away from the limiting cylinder 841. A pressing plate 8413 is hinged on the inner wall of the limiting slot 8412. A connecting rod 8414 is hinged on the lower side of the pressing plate 8413. The other end of the connecting rod 8414 is hinged on the upper side of the moving shaft 8410. When the spring 8415 is in the reset state, the end of the pressing plate 8413 away from its hinge point is tilted upward, so that the moving shaft 8410 can be driven to slide toward the interior of the hollow bar 847 when the pressing plate 8413 is pressed.

[0033] In the above scheme: when shooting, the handle 83 is turned to drive the worm 82 to rotate, the worm 82 drives the worm wheel 81 meshing with it to rotate, the worm wheel 81 drives the connecting piece 84 to swing, and then drives the plate 85 to move, so that the plate 85 moves to one side of the camera lens, and then the other plate 85 is moved to the other side of the camera lens in the same way, and then the pressing plate 8413 is pressed. Under the elasticity of the second spring 8415, the pressing plate 8413 drives the connecting rod 8414 to drive the moving shaft 8410 to move toward the inner direction of the hollow bar 847, so that one end of the moving shaft 8410 leaves the positioning groove 852 on the inner side of the card slot 851 and enters the card slot 851. At this time, the plate 85 can be slid to move the moving shaft 8410. One end of 410 slides in the card slot 851 inside the plate body 85 to adjust the height of the plate body 85. After the adjustment, release the button 8413, and the spring 8415 resets the movable shaft 8410, so that one end of the movable shaft 8410 is inserted into the corresponding positioning slot 852.
